Abstract
Wireless wide area network (WWAN) antenna with integrated sensor and methods of using the same. In one embodiment, an antenna subsystem and proximity sensing subsystem share a grounded antenna component/parasitic element. The parasitic element can be used to broaden the operating band of the antenna feeding component and provide an input (via a capacitance change) to a proximity sensor. The parasitic element is, in one embodiment, coupled in parallel to the proximity sensor allowing for a reduction in noise due to increased isolation between the antenna subsystem and the sensing subsystem.
