High-isolation, common-focus, transmit-receive antenna set

摘要

A common focus antenna (1) including three slot antennas sets (100, 200 and 300) formed in a metallic layer (70). The metallic layer (70) is supported by a substrate (75). Two slot antenna sets (100, 200) are arranged parallel to each other and perpendicular to a third antenna set (300) which is positioned between the two parallel slot antenna (100, 200) in the general shape of the letter "H". A lens (111) is provided on the substrate (75), opposite the metallic layer (70). <IMAGE> <IMAGE>
