Abstract
A dual frequency wideband antenna assembly for use in a wireless communication device. The antenna assembly having a first resonator element disposed away from the ground plane element, said first resonator element being operatively coupled at a first location to the ground plane and being operatively coupled at a second location to the RF signal port; a second resonator element disposed away from the ground plane. The first and second resonator elements are coupled via a bridge conductor and a capacitive tuning network. The capacitive tuning network may include a discrete capacitor or an adjustable capacitor which varies in response to a signal.
