Abstract :
A multilayer dual-port dual-circularly-polarized (CP) antenna was designed for Ku-band operation. The design is based on a truncated corner square-ring slot configuration with planar multilayer circuit board technology. High isolation is achieved between orthogonal ports while maintaining axial ratio lower than 3 dB for both senses of circular polarization. Highly efficient dual-CP operation makes this design attractive as a building block for passive and active array feeds for reflector antennas used in satellite communication applications.
