Abstract
A Potter horn and a compact orthomode transducer operating at 150 GHz are designed using full wave analysis. The Potter horn patterns have good symmetry within the main beam, the sidelobe level is less than 35 dB, and the cross-polarization level reaches 21 dB. The transmission test results of the orthomode transducer and feed horn show that the bandwidth(S11 <; -20 dB) is 16 GHz. The whole dimension is only (25 mm x 70 mm) , whereas the orthomode transducer dimension is (25 mm x 20 mm x 30 mm).
