Abstract:
In this paper, we present a new type of horn-reflector antenna The design employs an offset parabolic reflector fed by a Pickett-Potter horn. The horn is essentially a smooth-wall conical horn with a single step at its throat. This arrangement is a simplified version of the conventional Potter horn and is much easier to manufacture than the corrugated horn. We designed a Pickett-Potter horn-reflector antenna for a 700 GHz SIS mixer. We also developed and tested a 15 GHz scale model. We found that the Pickett-Potter horn and hom-reflector antenna has good beam circularity and a return loss value better than —25 dB over a bandwidth of about 15%.
