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

摘要

ABSTRACT OF THE DISCLOSUREA compact multi-layer flat antenna structure incorporating alow noise block down-converter on the power divider network layerof 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 indirect broadcast satellite (DBS) applications for single or dualorthogonal polarizations. The connection between the antenna andreceiver may be implemented in stripline/ coplanar waveguide, orother known technologies such as microstrip, slotline, andfinline.- 12 -
