Abstract

An antenna for transmission/reception of dual polarised radio signals comprises four patch assemblies (1, 2, 3, 4) and an elongated panel (5). The panel (5) and the patch assemblies (1, 2, 3, 4) are mounted on an elongated supporting base panel (6) of aluminium. Each patch assembly is formed by a stack of two circular panels, the lower of which (11) has on its lower surface a parasitic radiating element (12) formed by a copper track. The upper surface of the lower panel (11) is coated with copper in a circular shape except for two arc-shaped slots (13, 14) which separate two copper areas (15, 16) from the radiating patch (17). The element (12) is disposed wholly within the volume defined between the patch (17) and the panel (6), and the element (12) acts to reduce unwanted cross-couplings created by radiation from within the corresponding patch assembly. <IMAGE> <IMAGE>
