An antenna arrangement comprises a patch conductor (102) supported substantially parallel to a ground plane (104), a feed pin (106) connected to the patch conductor at a first point and a ground pin (108) connected between a second point on the patch conductor and the ground plane. The feed and ground pins are connected by a linking conductor (510) and have shunt capacitance means coupled across them. Suitable values of the capacitance means and the location and dimensions of the linking conductor enable a good match to the antenna to be achieved. The linking conductor may be directly connected to the patch conductor or there may be gaps between the feed and ground pins both above and is below the linking conductor. An impedance transformation may be provided by the feed and ground pins having different cross-sectional areas and/or by the provision of a slot in the patch conductor.
