REFLECTOR ANTENNA WITH COINCIDENT TRANSMIT-RECEIVE BEAMS PLUS CONICAL SCANNED RECEIVE BEAM |
摘要 |
An antenna system includes a feedhorn, main reflector, sub-reflector, and frequency selective member. The sub-reflector includes an axially symmetrical reflecting surface. The frequency selective member includes an axially non-symmetrical reflecting surface. The frequency selective member transmits signals having a first frequency from the feedhorn to the sub-reflector. These signals are symmetrically reflected by the sub-reflector to the main reflector. The frequency selective member reflects signals having a second frequency from the main reflector to the feedhorn. These signals are reflected at a small conical angle by the frequency selective member to the feedhorn. In this way, the present transmit/receive system provides coincident transmit and receive signals with only conically scanned receive signals. |
