Patent ID: 8446318

Claim:
A method of controlling an antenna-pattern of a beamforming antenna in a wireless device, comprising: calculating the input impedance of the beamforming antenna using an adaptive matching network, wherein said beamforming antenna includes a primary radiating element and one or more reconfigurable parasitic elements to shape and direct the antenna-pattern, and said primary radiating element and said reconfigurable parasitic elements cooperatively receive, transmit, or both a radio frequency signal; determining that the input impedance of the beamforming antenna is outside a tolerance; recognizing an environment of the wireless device; selecting a portion of said reconfigurable parasitic elements using the input impedance of the beamforming antenna, an input impedance observation table, said recognized environment, or any combination thereof; and updating the beamforming antenna by electrically connecting, electrically coupling, or both said selected portion of said reconfigurable parasitic elements to said primary radiating element to adaptively steer the antenna-pattern in a preferred direction.
