Abstract
A reconfigurable antenna system is described which combines active and passive components used to impedance match, alter the frequency response, and change the radiation pattern of an antenna. Re-use of components such as switches and tunable capacitors make the circuit topologies more space and cost effective, while reducing complexity of the control signaling required. Antenna structures with single and multiple feed and/or ground connections are described and active circuit topologies are shown for these configurations. A processor and algorithm can reside with the antenna circuitry, or the algorithm to control antenna optimization can be implemented in a processor in the host device.

An antenna system, comprising:
- a first dielectric block having a first surface and a second surface opposing the first surface;
- an antenna disposed on a first surface of the first dielectric block;
- a parasitic element disposed on the second surface of the first dielectric block such that at least a portion of the first dielectric block is disposed between the antenna and the parasitic element, wherein the parasitic element is configured to alter a frequency response of the antenna.
An antenna system, comprising:
- a first dielectric block having a first surface and a second surface, the second surface opposing the first surface;

- an antenna disposed on the first surface of the first dielectric block;
- a first parasitic element disposed on the second surface of the first dielectric block;
- a second parasitic element disposed on the second dielectric block.
