Patent ID: 8170498

Claim:
An antenna assembly of an integrated circuit comprises: an antenna having an antenna radiation section and an antenna ground plane formed on a second layer of the integrated circuit; a transmission line having a first line and a second line formed on the second layer of the integrated circuit, wherein the first and second lines are coupled to the antenna radiation section; a first conductor formed on a first layer of the integrated circuit and electromagnetically coupled to the first line to form a first transformer; a second conductor formed on the first layer of the integrated circuit and electromagnetically coupled to the second line to form a second transformer; a third conductor formed on a third layer of the integrated circuit and electromagnetically coupled to the first line to form a third transformer; and a fourth conductor formed on the third layer of the integrated circuit and electromagnetically coupled to the second line to form a fourth transformer, wherein the first and second transformers support an inbound signal and the third and fourth transformers support an outbound signal.
