Highly Selective Circularly Polarized Filtering Slot Antenna Based on Stub-Loaded Resonators [PDF]
This letter presents a novel approach to designing a highly selective circularly polarized (CP) filtering antenna. It is based on rectangular waveguide cavity resonators that are directly coupled to each other. Capacitive stubs are loaded onto the cavity
