Topic: Evolution of Reflector Antennas in Diverse Applications: From Archimedes’ Burning Mirror to Innovative CubeSat Antennas

Abstract: Reflector antennas are perhaps the most recognized type of antennas with vast applications in satellite communications, radars, wireless communications, remote sensing, planetary missions, radio astronomy and others.  This is an antenna topology that is never gets old with ample modern applications. Typical frequency ranges of operations have been as low as the P-band, microwave, millimeter wave, and as high as Terra Hertz and optical. Reflector antenna designs have evolved from simple single parabolic dish with a solid surface to sophisticated mesh reflector antennas with multiple surfaces. The basic role of a reflector antenna is to confine most of the electromagnetic energy captured over their apertures into a focal plane or redirect the radiated field of the feed into the far field. This invited keynote talk focuses on a concise history of reflector antenna evolution over an extended historical time span, dating back to Archimedes, and links it to the recent and challenging developments of innovative reflector antennas for CubeSats, etc.  The author particularly confines his presentation material to the areas that have influenced his research activities including novel designs and optimizations, simulations and measurements of reflector antennas. The material presented in this overview talk is the summarized version of many journal and conference papers and book chapters co-authored by the author and his contributions to the original designs of many currently functioning communications, remote sensing, radio astronomy and radar antenna systems.
