Radio frequency lens antenna
Abstract
Multiple beam antennas are modified and improved through the use of lenses coupled together by hybrid junctions. A dual lens structure avoids circulators while permitting the lenses to be used both for transmission and for reception. A six lens structure provided perfect phase focusing utilizing an R-2R geometry with a Mobuis topology, giving 360 degrees of independent antenna beams from a single circular or cylindrical antenna array.
