Abstract
T Traditional circularly polarized (CP) horn antennas use a septum (or a partition) based feed, which is difficult to fabricate beyond 60 GHz. As an alternative, here we propose hexagonal waveguide based CP antenna design that is fabrication friendly and low-cost. Design, fabrication and characterization is shown for an F-band prototype. The prototype exhibits 18 dBi mid-band gain with three dB axial-ratio (AR) bandwidth beyond thirty percent.
