<p>Methods, devices, and systems for controlling a beamforming antenna (341) with reconfigurable parasitic elements are provided. In one embodiment, a method of controlling a beamforming antenna in a wireless device comprises calculating the input impedance of the beamforming antenna using an adaptive matching network (342), wherein said beamforming antenna includes a primary radiating element and one or more reconfigurable parasitic elements, and said primary radiating element and said reconfigurable parasitic elements cooperatively receive, transmit, or both a radio frequency signal; determining the input impedance of the beamforming antenna (341) is outside a tolerance; recognizing the environment of the wireless device; selecting a portion of said reconfigurable parasitic elements using the input impedance of the beamforming antenna, a predetermined input impedance observation table, said recognized environment, or any combination thereof; and updating the beamforming antenna (341) by electrically connecting, electrically coupling, or both said selected portion of said reconfigurable parasitic elements to said primary radiating element.</p> |
