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.

A wideband adjustable antenna assembly for use in a wireless communications device, said device having an input/output RF signal port and a ground plane, said antenna assembly comprising:
- 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;
- a bridge conductor conductively coupling the first and second resonating elements;
- and
- a capacitive tuning network operatively coupled to the first and second resonating elements, said capacitive tuning network capacitively coupling the first resonating element to the second resonating element.
