ATI's Microwave Antenna Principles and Practice in Commercial and Government Sectors course

Share |


Technical Training Short On Site Course Quote

    Microwave antennas are indispensible for wireless and RADAR applications in commercial and government environments. This three - day course covers the theory and practice of microwave antenna design and test, providing a thorough grounding in their principles and technology. After considering the physical foundations of microwave antennas, we move to discussions of specifications for performance for various designs: primary elements (monopoles, dipoles, slots, helixes, and patches), reflector antenna systems (prime focus and folded optics, center-fed and offset-fed), and array antennas (planar arrays and phased arrays). Array antennas figure prominently in current and future applications and so are considered in detail later in the course. Installation of microwave antennas on vehicles, aircraft (manned and unmanned) and vessels is reviewed in detail as there are many timely applications in government and industry. Innovation in phased array antennas is covered based on case studies in space communications and terrestrial wireless. The integration of microwave principles and digital processing is described in the context of adaptive antennas, including MIMO and Smart Distributed Antenna Systems. Prediction of microwave antenna performance using software modelling tools is reviewed, including techniques for metallic structures and adaptive arrays. Measurement techniques are key to a successful antenna, so we consider the standard procedures for antenna measurement (anechoic near field ranges and far field ranges) as well as innovative approaches like the compact antenna range. Microwave antennas may pose a challenge when being installed on aircraft, ships and vehicles and so we review their integration under such constraints. The course wraps up with reviews of recent topics related to microwave antennas, including the NASA SCaN Test Bed on the International Space Station and a UAV case study.



    Bruce Elbert is a recognized SATCOM technology and network expert and has been involved in the satellite and telecommunications industries for over 35 years. He consults to major satellite organizations and government agencies in the technical and operations aspects of applying satellite technology. Prior to forming his consulting firm, he was Senior Vice President of Operations in the international satellite division of Hughes Electronics (now Boeing Satellite), where he introduced advanced broadband and mobile satellite technologies. He directed the design of several major satellite projects, including Palapa A, Indonesia's original satellite system; the Hughes Galaxy satellite system; and the development of the first GEO mobile satellite system capable of serving handheld user terminals. He has written seven books on telecommunications and IT, including Introduction to Satellite Communication, Third Edition (Artech House, 2008), The Satellite Communication Applications Handbook, Second Edition (Artech House, 2004); and The Satellite Communication Ground Segment and Earth Station Handbook (Artech House, 2001). Mr. Elbert holds the MSEE from the University of Maryland, College Park, the BEE from the City University of New York, and the MBA from Pepperdine University. He is adjunct professor in the College of Engineering at the University of Wisconsin - Madison, covering various aspects of data communications, and presents satellite communications short courses through UCLA Extension. He served as a captain in the US Army Signal Corps, including a tour with the 4th Infantry Division in South Vietnam and as an Instructor Team Chief at the Signal School, Ft. Gordon, GA.
