Abstract:
1. An antenna assembly for a wireless communication device comprising: a dielectric substrate; a ground plane supported by the dielectric substrate; a first radiating element disposed on the substrate; a first port coupled to the first radiating element for applying a first signal that excites the first radiating element; a second radiating element disposed on the substrate and spaced apart from the first radiating element; a second port coupled to the second radiating element for applying a second signal that excites the second radiating element; a first meandering slot interposed on the ground plane between the first radiating element and the second radiating element wherein a start of the first meandering slot is at an edge of the ground plane and progresses inwardly from the edge in a region between the first radiating element and the second radiating element to provide isolation between the first radiating element and second radiating element; and a third port coupled to an end remote to the start of the first meandering slot for applying a third signal that excites the first meandering slot to operate as a third radiating element while providing said isolation between the first radiating element and second radiating element to reduce coupling between said first radiating element and second radiating element.
