ABSTRACT:
An adjustable integrated circuit antenna structure includes a plurality of antenna elements, a coupling circuit, a ground plane, and a transmission line circuit. The coupling circuit is operable to couple at least one of the plurality of antenna elements into an antenna based on an antenna structure characteristic signal, wherein the antenna has at least one of an effective length, a bandwidth, an impedance, a quality factor, and a frequency band in accordance with the antenna characteristic signal. The ground plane is proximal to the plurality of antenna elements. The transmission line circuit is coupled to provide an outbound radio frequency (RF) signal to the antenna and receive an inbound RF signal from the antenna.
