About Annual Symposium of the Antenna Measurement Techniques Association, AMTA

Annual Symposium of the Antenna Measurement Techniques Association, AMTA — Conference Proceedings Profile

An honest label comes first. The title catalogued on this record, the Annual Symposium of the Antenna Measurement Techniques Association, shortened everywhere in its field to AMTA, is not a journal. It is the published proceedings of the annual symposium of the Antenna Measurement Techniques Association, the professional community of the engineers and metrologists who measure antennas, radomes and radar cross-section for a living. Each autumn the association meets for about a week, roughly one hundred peer-reviewed technical papers are presented, and those papers are gathered into a citable proceedings record that bibliographic databases track as a continuing serial — which is why the series carries ISSNs and appears in a journal directory at all. The two identifiers stored on this JournalsWorld record are 2474-2740 and 2380-1840. Readers who arrive here looking for a journal with monthly issues, a standing editor-in-chief and a rolling submission window will not find one, and this profile does not pretend otherwise. What they will find is one of the oldest specialist meetings in electromagnetic measurement, running since 1979, whose proceedings form a unique archive of how antenna measurement actually developed.

Identity and history

AMTA began, as many durable professional communities begin, as a users' group that outgrew its original purpose. According to the association's own history, Joseph Pape of Scientific-Atlanta held organising meetings across the United States in 1978 with the intention of forming a user group for a Scientific-Atlanta antenna pattern measurement system. The response to his questionnaire showed a wider hunger: practitioners wanted a forum covering antenna, radome and radar cross-section measurement as a whole, not one vendor's equipment. An organisational meeting followed in March 1979, and the first Annual Business Meeting and Symposium was hosted by Scientific-Atlanta at the Presidential Hotel in Atlanta on 18 October 1979. About eighty founding members attended, nineteen technical papers were presented, and the annual membership fee, included with registration, was ten dollars. The meeting closed with two decisions that still define the series: the symposium would be held every year, and its location would alternate between the East and West coasts of the United States.

The association was incorporated in the state of Georgia on 10 March 1989 as a non-profit professional organisation open to individuals with an interest in antenna measurements. Membership, in AMTA's own account, grew from about thirty in 1979 to about five hundred today, drawn from industry, government and educational institutions in many countries. The symposium grew with it: recent editions run for a full week in October or November, attract around five hundred attendees, and present approximately one hundred technical papers, alongside an exhibition in which manufacturers demonstrate measurement hardware, systems and services, short courses and boot camps on measurement practice, student activities, and tours of local measurement facilities, traditionally arranged for the last day. The numbering tells the same story of continuity — the 2025 edition, held in Tucson, was billed as the 47th annual symposium, and the 2024 edition met from 27 October to 1 November 2024 in the greater Cincinnati area, at the Northern Kentucky Convention Center.

The proceedings are the written residue of that meeting, and AMTA treats them as an archive rather than a by-product. The association notes that its archive of symposium papers now amounts to well in excess of three thousand individual contributions spanning almost every conceivable aspect of antenna, radar reflectivity and associated measurements, and that within it the development of several significant innovations can be traced from first inception to mature implementation. Papers from the symposium are available on disc and online in the association's archival database, and individual recent papers carry digital object identifiers in the pattern 10.23919/AMTAP followed by the year and a paper number, as visible in citations of the 2019 edition's papers in the wider measurement literature.

What the symposium covers

AMTA's own statement of its areas of interest is a compact map of the measurement craft:

• Measurement facilities — the design, evaluation and comparison of the ranges and chambers in which antennas are measured.
• Unique or innovative measurement techniques, including near-field techniques and their applications.
• Test instrumentation and systems, and the interfacing problems that arise when equipment from different makers must work together.
• Radar cross-section (RCS) measurements — how objects scatter, and how that scattering is measured honestly.
• Compact range design and evaluation.
• Practical aspects of measurement problems and their solutions — the session-level knowledge of what goes wrong in a real range and how experienced practitioners fix it.

The call for the 2025 symposium shows how that territory has widened with the technology. Its hot topics included 5G wireless technology, antennas and radar in automotive applications, Internet of Things and machine-to-machine applications, massive MIMO advances, medical applications, robotics in antenna measurements, satellite and space applications, and compressive sensing in antenna measurements. Its additional topics ran from hardware-in-the-loop testing and millimetre-wave, terahertz and quasi-optical measurement, through measurement standards and laboratory comparisons, near-field, far-field, compact and RCS range techniques, new test instrumentation, data acquisition and processing, diagnostic methods for antenna acceptance testing, phased array applications and measurements, chamber design for electromagnetic interference and compatibility work, and in-situ testing and channel sounding. A paper belongs at AMTA when its contribution is, at heart, about measuring something electromagnetic well — a new range, a calibration method, an uncertainty budget, a comparison between facilities — rather than about a new antenna design alone, however elegant that design may be.

How the proceedings work, and how to take part

Because AMTA is a conference, participation follows the conference rhythm rather than the journal rhythm. An author prepares a paper for a specific edition, under that edition's call for papers and deadlines, submits it months ahead of the autumn meeting, and — if it passes the edition's review — presents it at the symposium, after which it enters that year's proceedings. The association supports the next generation of the field deliberately: the 2025 call announced at least three Best Student Paper Awards, each carrying a cash award of 500 United States dollars, a complimentary registration at the following year's symposium and a year of AMTA membership, together with a named student travel scholarship, with award recipients required to present their papers in person. Student Day activities at earlier editions brought local college students into technical sessions and in front of exhibitors, part of a long-running effort by the organisers to address the shortage of technical professionals entering electromagnetics.

Membership and attendance are the other two routes into the record. AMTA is open to individuals with an interest in antenna measurements, and its members come from industry, government laboratories and universities worldwide. Beyond the annual symposium, the association hosts smaller regional events through the year in the United States on particular aspects of antenna measurement, and its community overlaps with the measurement committees of the wider IEEE antennas community — a connection visible in joint workshops at European antenna conferences, where AMTA workshops on topics such as multi-beam antenna measurement techniques have been run for the broader profession. For a researcher deciding where a measurement paper will be read by the people most likely to use it, that concentrated audience — facility managers, calibration specialists, range designers and the instrument makers who equip them — is the symposium's real offering.

Metrics and indexing — read with care

Proceedings series attract journal-style numbers, and those numbers mislead when they are read as journal numbers. This record's stored data carry an h-index of 2 and a Q4 label, figures that come from the Scopus-derived data behind the original catalogue entry, whose coverage line began only in 2024. That coverage window alone should warn readers: it describes one recent snapshot of the series in one database, not the standing of a meeting whose archive runs back to 1979. The independent checks made for this profile underline the point. A Directory of Open Access Journals search for each of the two ISSNs returned no record, which is expected for a conference proceedings series and says nothing about quality. Resolving the ISSNs through OpenAlex likewise produced no usable citation picture: one ISSN returned no source record at all, and the other resolved to a source record holding zero works. OpenAlex's coverage of this proceedings series is therefore effectively absent, and this profile reports no OpenAlex works, citation or h-index figures for AMTA, because there are none worth reporting. The honest summary is that AMTA should be judged the way its own community judges it — by the longevity of the meeting, the quality and practical utility of its papers, the size and expertise of its audience, and the place of its archive in the measurement literature — rather than by a quartile borrowed from a partial database window. Authors whose institution counts Scopus-indexed conference papers should confirm the current status of the series in the Scopus source list for the edition year they care about, because proceedings coverage is decided edition by edition and database by database.

Is this venue right for your work?

AMTA is a strong fit for engineers, metrologists and researchers whose paper reports a measurement: a range or chamber design or evaluation, a near-field or compact-range technique, a calibration or uncertainty study, an RCS measurement method, a facility comparison, or hard-won practical solutions to measurement problems in areas from automotive radar to satellite antennas and over-the-air testing for wireless systems. It is a weaker fit for work whose contribution is a device or antenna design with measurement used only as routine validation, for pure theory with no measurement consequence, and for authors who need a journal article — with a journal's citation pattern and issue structure — for a promotion or funding rule. Its attractions are the attractions of a mature specialist community: nearly five decades of continuity, an audience of about five hundred specialists who attend specifically to argue about measurement, an exhibition floor of the instrument trade, and a permanent archive of more than three thousand papers in which a good measurement technique can be found, cited and built on for decades.

Reading and using the archive

For working engineers, the archive is the symposium's most durable product, and it rewards being read as a historical record rather than as a pile of isolated papers. Because the same community has met every year since 1979, a reader can follow a measurement problem across decades: early papers on the first automated antenna pattern systems and near-field scanning sit in the same series as recent work on robotic measurement arms, over-the-air testing for millimetre-wave devices and measurement imaging. The association's own archive spotlight series was created for exactly this kind of reading: authored by a leading practitioner, each spotlight article takes an important line of innovation documented in the symposium papers, explains the historical context in which it first appeared, and brings the story up to date with more recent developments. Newcomers to a measurement topic can use those narratives as a guided entry point, then follow the citations back into the underlying papers.

Citing the proceedings correctly matters, because the series is catalogued differently in different systems. A citation should name the specific paper, its authors, the symposium edition and year, and the paper's digital object identifier where one exists — recent papers carry DOIs in the 10.23919/AMTAP pattern — rather than citing the series as though it were a journal volume. Librarians catalogue the continuing series under its ISSNs, 2474-2740 and 2380-1840 as stored on this record, while treating each edition's volume as its own publication. Authors checking whether a particular year's proceedings were indexed should verify that edition specifically, since indexing services handle conference series edition by edition, and coverage of one year is not proof of coverage of the next. The stored record behind this profile, with its short recent coverage window, is itself an illustration of that patchwork: the catalogue snapshot and the forty-seven-edition reality are both true, and they describe different things.

Similar and related venues

Authors comparing measurement-focused venues should also look at the IEEE Conference on Antenna Measurements and Applications (CAMA), a younger IEEE Antennas and Propagation Society conference devoted specifically to antenna measurement and its applications, whose proceedings carry different ISSNs and a different, more application-facing programme. The ARFTG Microwave Measurement Conference serves the neighbouring community of radio-frequency and microwave measurement — calibration, on-wafer probing and nonlinear measurement — and its proceedings form a separate numbered series. For antenna work more broadly, the IEEE Antennas and Propagation Society's own annual symposium digest and the Mediterranean Microwave Symposium are larger, wider meetings whose proceedings appear in the same databases. None of these is AMTA: the comparison should start from the paper, and a paper about the measurement itself, judged by the people who run the world's antenna ranges, is the paper AMTA exists for.

Frequently Asked Questions

What are the ISSNs of the AMTA symposium proceedings?
The ISSNs stored on this record are 2474-2740 and 2380-1840. They identify the continuing proceedings series of the annual AMTA symposium.

Is AMTA a journal?
No. AMTA is the Antenna Measurement Techniques Association, a non-profit professional organisation formed in 1979. Its annual symposium is a conference, and this record documents the symposium's published proceedings — a serial record of conference papers, not a periodical journal.

Who organises the symposium?
The Antenna Measurement Techniques Association itself. AMTA was incorporated in Georgia, United States, on 10 March 1989, and its members — about five hundred today — come from industry, government and educational institutions worldwide.

When and where is the symposium held?
Annually, for about a week, usually in October or November, at a United States venue that traditionally alternates between coasts. The 2024 edition met in the greater Cincinnati area and the 2025 edition, the 47th, met in Tucson.

How many papers does an edition present?
Approximately one hundred technical papers, to an audience of around five hundred attendees, per the association's own description. Across its history the symposium archive holds well in excess of three thousand papers.

How do I publish in the AMTA proceedings?
By submitting a paper to a specific edition under that year's call for papers, presenting it at the symposium if it is accepted, and appearing in that edition's proceedings. There is no rolling journal submission window.

What metrics does the series have?
The stored catalogue data carry an h-index of 2 and a Q4 label from a recent Scopus-derived coverage window. OpenAlex returned no usable source metrics for either ISSN in the checks for this profile, and DOAJ holds no record, as expected for proceedings. Judge the venue by conference standards — longevity, audience and archive — rather than by those partial figures.

What does AMTA stand for?
Antenna Measurement Techniques Association. The name states the association's territory exactly: the techniques by which antennas — and radomes and radar cross-section — are measured, and the facilities, instruments and standards those techniques depend on.

Does AMTA support students?
Yes. Recent calls have offered Best Student Paper Awards with a cash prize, a complimentary following-year registration and a year of membership, plus a named student travel scholarship, alongside Student Day activities at the symposium.
