Abstract
An antenna set comprising at least one antenna element and a ground plane, is complemented by a conductive element coupled to the ground plane, so as to modify the frequency performance of the antenna set, adding an operating band to the antenna set, and/or increasing the bandwidth of one operating band of the antenna set, and/or enhancing voltage standing wave ration, efficiency and/or gain of the antenna set. Thus, the conductive element can be used to tune the antenna set in accordance with specific requirements concerning, for example, compatibility with different wireless services.
