Abstract:
An embodiment of the present invention is an apparatus, comprising a tunable antenna including a variable reactance network connected to the antenna a closed loop control system adapted to sense the RF voltage across the variable reactance network and adjust the reactance of the network to maximize the RF voltage. The variable reactance network may comprise a parallel capacitance or a series capacitance. Further, the variable reactance networks may be connected to the antenna, which may be a patch antenna, a monopole antenna, or a slot antenna.
