Patent ID: 6850191

Claim:
An antenna assembly comprising: a first antenna having a first planar substrate of dielectric material with two major surfaces, a first electrically conductive layer on one of the two major surfaces, a second electrically conductive layer on another one of the two major surfaces, and at least one primary electrical shunt connected to the first electrically conductive layer and the second electrically conductive layer; a second antenna having a second planar substrate of dielectric material with a pair of major surfaces, one of the pair of major surfaces having a third electrically conductive layer thereon and another one of the pair of major surfaces facing the first antenna, the second antenna having at least one secondary electrical shunt connecting the third electrically conductive layer to the first electrically conductive layer of the first antenna; and a pair of electrical conductors each being connected to a different one of the second and third electrically conductive layers to carry communication signals to and from the antenna assembly.
