Patent ID: 8085202

Claim:
An antenna assembly for a wireless communication device comprising: a ground plane formed by a layer of electrically conductive material on a substrate of non-conductive material, wherein the layer of electrically conductive material has a thickness; a first slot antenna formed by a first radiation slot in the layer of electrically conductive material; a second slot antenna formed by a second radiation slot in the layer of electrically conductive material and spaced from the first slot antenna by at least one-tenth wavelength of a resonant frequency of the second slot antenna; a first isolation slot formed in the layer of electrically conductive material and located between the first slot antenna and the second slot antenna, wherein the first isolation slot comprises a slot having a meandered pattern that starts at an edge of the layer of electrically conductive material; a first signal port coupled to the first slot antenna; and a second signal port coupled to the second slot antenna, wherein the first radiation slot, the second radiation slot and the first isolation slot all pass through the thickness of the layer of electrically conductive material.
