| Abstract: | This paper presents a novel technique to improve the cross- polarization and the beam e±ciency of an o®set parabolic re°ector antenna used for space borne radiometric applications. A special multi-mode primary feed (tri-mode conjugate matched feed) is used to illuminate the o®set parabolic re°ector antenna. The simulated data on the radiation characteristics of the o®set parabolic re°ector antenna with a matched feed has been compared with that of a conventional Potter horn. It is observed that the tri-mode feed suppress the unwanted high cross-polarization of an o®set re°ector antenna and improves the beam efficiency. |
