Abstract:
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 and having a geometric center, a second electrically conductive layer on another one of the two major surfaces and having another geometric center, and at least one electrical shunt connected off center to the first electrically conductive layer and connected off center to the second electrically conductive layer;a transmission medium connected to substantially the geometric center of the first electrically conductive layer and connected to substantially the geometric center of the second electrically conductive layer to carry communication signals to and from the first antenna;a second antenna having a second planar substrate of dielectric material with first and second major surfaces, the first major surface facing the first electrically conductive layer of the first antenna, and having a conductive pattern on the second major surface; anda secondary conductor extending through one of the at least one electrical shunt and connected to the conductive pattern.
