Reconfigurable Linear/Circular Polarization Rectangular Waveguide Filtenna

open access: yesIEEE Transactions on Antennas and Propagation, 2018
We introduce a new reconfigurable linear polarization and circular polarization (CP) antenna, based on a rectangular waveguide (RWG) and a novel reconfigurable polarizer. The polarizer consists of two orthogonal apertures. The apertures transform the linear polarization of the dominant mode of the RWG antenna to CP. Each of these apertures is loaded by
