Low-noise-block downconverter for use with flat antenna receiving dual polarized electromagnetic waves.

摘要

A low-noise-block downconverter (LNB) for use with flat antennas receiving dual polarized electromagnetic waves includes a body case (11) mounted to rear side surface of the planar antenna, the body case having two wave guide input parts (14) corresponding to wave guide apertures of the antenna and enclosing a selective device alternatively allowing either one of two outputs corresponding to two different type polarized electromagnetic waves received. The LNB can be thereby made compact and minimized in thickness and weight. <IMAGE>
