ABSTRACT:
An antenna system includes an antenna, a transmission line, an inductor module, a tunable capacitor module, and control logic. The transmission line is coupled to the antenna and to the inductor module. The tunable capacitor module is coupled to the transmission line in accordance with a capacitance control signal to provide a desired capacitance such that inductance of the inductor module and the desired capacitance tunes the antenna system. The control logic is coupled to generate the capacitance control signal based on the operational parameters.
