Abstract

A dual polarisation antenna has a feed network comprising two feed channels 15, 16 which divide into feed lines 15a, 15b, 16a, 16b respectively coupled to four slots 13a, 13b, 14a, 14b. The four slots are in registration with and couple to four patches 10a, 10b, 12a, 12b which are in turn coupled to a radiating coating 5. <IMAGE> <IMAGE>
