Abstract: A plug-and-play antenna may be used with many different types of wireless communication devices. An antenna may be coupled to an impedance tuning component and a waveform generator. A calibration control module receives radio status information, controls the waveform generator to vary a response of the antenna, and tunes the impedance tuning component to match impedances between a radio and the antenna.
