“Design of Electrically Small Antennas” by Steven Best, sponsored by the IEEE Antennas and Propagation Society As today’s ubiquitous wireless devices decrease in size, there is an increasing demand for physically smaller antennas, yet the performance requirements are rarely relaxed. Optimizing the performance properties of electrically small antennas represents a significant design challenge for the antenna engineer. This course provides a discussion on the fundamental theory, challenges and performance trade-offs associated with the design of electrically small antennas. The course begins with a brief overview of the basic theory and concepts associated with electrically small antennas. This segment of the presentation provides an understanding of antenna performance limitations in terms of impedance, radiation patterns, bandwidth, efficiency, and quality factor. Techniques used to design self-resonant electrically small antennas are described and compared. These include dielectric loading, linear loading (increasing wire length), top-loading, and “folded” configurations. The relationship between the antenna’s performance characteristics and its physical properties is discussed. Issues such as the significance of antenna geometry are considered. The performance of the small antenna on small finite ground planes is considered with a particular emphasis on how the antenna’s location on the ground plane affects impedance, pattern and polarization properties. The course concludes with a discussion on recent advances made in the design of low profile, conformal and integrated device antennas. After completing you should be able to develop an understanding of:
Steven R. Best received the B.Sc.Eng and the Ph.D. degrees in Electrical Engineering from the University of New Brunswick, Canada in 1983 and 1988, respectively. He has over 20 years of experience in business management and antenna design engineering in both military and commercial markets. He is currently a Principal Sensor Systems Engineer with the MITRE Corporation in Bedford, MA where he is involved in supporting a number of government programs. Dr. Best is an Adjunct Professor at Northeastern University, Tuft’s University and UMass-Lowell. He is the author or co-author of over 100 papers in various journal, conference and industry publications. He was the 2004 and 2005 recipient of the AFRL Sensors Directorate Chief Scientist Award. He was formerly a Distinguished Lecturer for the IEEE Antennas and Propagation Society and an Associate Editor for the IEEE Antennas and Wireless Propagation Letters. Dr. Best is a frequent reviewer for several IEE and IEEE journals. He is an Associate Editor of the IEEE Transactions on Antennas and Propagation, a member of the IEEE APS AdCom and Junior Past Chair of the IEEE Boston Section.
