ABSTRACT:
A wireless communications antenna system (100) includes a main circuit element (102) having a feed device (104) with an active port (108) and a grounding port (110), where the grounding port is coupled to a grounding device (106) of the main circuit element, a generally planar antenna element (112) having a feeding portion (114) coupled to the active port of the feed device, where the antenna element is electrically ungrounded, and a generally planar secondary circuit element (116) having a grounding portion (118) coupled to the grounding device. The secondary circuit element is positioned in proximity to the antenna element and the antenna element and the secondary circuit element are generally parallel and separated by a gap (X). Further, at least a portion of the secondary circuit element at least partially overlaps the antenna element.
