Abstract
An aperture-coupled antenna, comprising at least one antenna element including a number of substantially planar, mutually parallel radiating patches (1-3) being fed with microwave power from a feed network (6) via an aperture (5a, 5b) in a ground plane layer (4). The feed network (6) feeds microwave power in at least two separate frequency bands, including a first, relatively low frequency band and a second, relatively high frequency band. A first patch (2) radiates microwave power in the first frequency band and is provided with an aperture (9a, 9b) so as to couple microwave power in the second frequency band to a second patch (1), the microwave power in the second frequency band being fed from the feed network (6) via the apertures (5a, 5b; 9a, 9b) in the ground plane layer (4) and the first patch (2) to the second patch (1).
