LOW NOISE BLOCK DOWN-CONVERTER FOR DIRECT BROADCAST SATELLITE RECEIVER INTEGRATED WITH A FLAT PLATE ANTENNA

摘要

A compact multi-layer flat antenna structure incorporating a low noise block down-converter on the power divider network layer of the antenna. RF circuit losses are reduced, and the antenna/receiver combination is made more compact, for flush mounting. The antenna/receiver combination finds particular utility in direct broadcast satellite (DBS) applications for single or dual orthogonal polarizations. The connection between the antenna and receiver may be implemented in stripline/ coplanar waveguide, or other known technologies such as microstrip, slotline, and finline.
