摘要：
A compact W-band cylindrical waveguide horn antenna with polarizer structure is designed which offers wideband left-hand circular polarization (LHCP) and symmetric radiation pattern. It has wideband impedance matching below S-11=-15 dB and axial ratio below 1.8 dB from 79.5 GHz to 87.5 GHz. This horn is used as a feed source for an offset parabolic reflector. The reflector antenna provides peak RHCP (right-hand circular polarization) directivity of 37.3 dBic at 86 GHz.
