From the 4th of November through the 9th, the Antenna Measurement Techniques Association (AMTA) held its 29th annual symposium in St. Louis, MO. AMTA is a non-profit, professional organization that promotes advances in electromagnetic technologies applicable to antenna and radar cross-section measurements. The organization was created in the late 1970s by a small group of engineers and even today the conference maintains the feeling of a close, tight knit and highly focused community. For engineers and organizations in antenna development, measurements or antenna integration, this is a conference well worth attending. Over the years, the conference organizers have done an excellent job of arranging the program to allow attendees and exhibitors to get the maximum amount of peer-to-peer interaction, something hard to do at much larger shows. The show organizers and hosts do an excellent job in arranging a program that allows attendees to attend all tracks and still meet with equipment vendors to discuss the latest technology. This event drew more than 500 AMTA global members from industry, government and educational institutions to discuss the state-of-the-art in measurement theory and applications. The conference recognized the contributions of several members, presenting the AMTA Distinguished Service Achievement Award given to Ms. Janet O’Neil and Dr. Inder Gupta, as well as the formation of the Dr. Edmond S. Gillespie Engineering Fellowship, which was awarded to 20 distinguished AMTA members.

St. Louis, MO is an ideal setting for the 2007 AMTA conference. The city is home to corporate headquarters of many hi-tech companies such as Monsanto, Boeing's Integrated Defense and Phantom Works sectors, ESCO Technologies, and Anheuser-Busch (after all, conferences shouldn’t be all work). Missouri features an esteemed educational foundation of 26 local institutions of higher learning. Washington University in St. Louis, University of Missouri Rolla, and St. Louis University are just a few of the internationally recognized private research universities.

Technical Program

Sunday

The short courses held on Sunday were focused on the Fundamentals of Antenna Measurements starting with the beginning concepts for measurement technique and building to advanced topics by the end of the lecture. The one-hour courses presented by Dr. Ed Joy covered fundamentals, near and far-field measurement techniques, anechoic chamber techniques, compact measurements and applications of antenna measurements. Dr. Joy is an IEEE Life Fellow holding BSEE, MSEE and PhD degrees in electrical engineering from the Georgia Institute of Technology and is currently Professor Emeritus of Electrical and Computer Engineering at his alma mater. An international lecturer, consultant and author, he has devoted 35 years to conducting research, teaching and consulting on antenna development and measurement techniques, and has presented 300+ seminars and published 200+ technical papers/research reports. Dr. Joy has also developed patents, including the flower petal reflector antenna, and has designed 20+ major antenna measurement facilities.

Monday

The advanced technical program got underway on Monday with a Keynote speech “AMTA and Boeing: Partners in Advancing Aerospace” by Don C. Winters, Vice President of Engineering and Information Technology at the Boeing Co. Phantom Works. Mr. Winter is a St. Louis native and has been employed at Boeing for 30 years with BS and MS degrees in Physics from the University of Missouri and an MBA from Washington University. Don currently leads the Engineering and Information Technology organization at the Boeing Phantom Works, a team of 1,100 engineers and scientists performing leading edge research spanning domains ranging from avionics and vehicle management systems to C4ISR to commercial aircraft.

Session one and two filled the first morning with presentations on near-field range issues and range design and evaluation. Speakers from both industry and academia focused on improving measurement accuracy (Near Field Measurement Errors Due To Neglecting Probe Cross-Polarization; Three-Dimensional Near Field/Far Field Correction; Extracting The Polarization From Bi-Polar Phase-less Near-Field Measurements; Mission to MARS - In Search of Antenna Pattern Craters, and various antenna measurement applications: “Conical Near-Field Antenna Measurement System;” “A Practical Application of an R-Card Fence; A Compact But Highly Flexible 5-Axis Positioner;” “A Method To Correct Measurement Errors In Far-Field Antenna Ranges;” and “A Comparison Of Measurements on a Dual-Receiver Antenna Range and Unique Application Of Chebyshev Absorbers.”

Tuesday was also Student Day Activities, where local college students were invited to the AMTA symposium to sit in on one or two technical paper sessions, fly Boeing’s F/A-18 flight simulator and visit with exhibitors. Various factors have kept many US students from pursuing careers in science and engineering, leading to a growing shortage of technical professionals. To address the growing opportunities for technical graduates now, AMTA organizers presented a panel discussion featuring government, academic and industrial professionals in the “Electromagnetics Research and Development” field. These professionals led a roundtable discussion of misperceptions and issues of the engineering field as well as career opportunities for graduates.
