<p>A patch array microwave antenna for microwave and millimetre wavebands comprising spaced subarrays each consisting of a surface fed patch (1) and a pair of parasitic patches (3a, 3b) fed from the non radiative edges of the fed patch (1), all on a substrate. In one example, the parasitic patches (3a, 3b) are the same length as the fed patch (1), but only around 50 % of its width, and are widely spaced. Useful as a broadband receiver, e.g. for video distribution.</p> |
