MICRO-STRIP PLANAR ARRAY ANTENNA FOR SATELLITE TELECOMMUNICATIONS, ADAPTED TO OPERATE AT DIFFERENT RECEPTION AND TRANSMISSION FREQUENCIES AND WITH CROSS-POLARIZATIONS

摘要

A micro-strip planar array antenna is disclosed, having a radiation surface (S) comprising first radiating elements (12T) arranged for operating in transmission and second radiating elements (12R) arranged for operating in reception, and a signal feeding network arranged on a plane parallel to the radiation surface (S), including micro-strip lines (120) ca- pacitively coupled to the aforementioned elements (12R, 12T). The first and second radiating elements (12R, 12T) are made on a same radiation surface (S) of the antenna according to an intercalated configuration, and are adapted to operate at different frequency ranges and perpendicular polarizations.
