Abstract
A dual frequency wideband antenna assembly for use in a wireless communication device. The antenna assembly includes a first radiating element having two substantially collateral arms with a dielectric member therebetween and a second radiating element having two substantially collateral arms also with a dielectric member therebetween. A conducting element operatively connects the first and second radiating elements to each other in an adjacent and substantially coplanar relation. The assembly is spaced a predetermined distance from the ground plane of a printed wiring board and is operatively connected thereto at several predetermined locations by several components. One component, a capacitor, operatively couples one of the arms of the first radiating element to a ground plane while other components, namely a feed element and a grounding element operatively connect one of the arms and a portion of the second radiating element, respectively, to the ground plane. Various componentry may be positioned within the open space(s) between the antenna assembly and the ground plane to facilitate compact construction.
