Abstract
A tunable dual band antenna system is disclosed. The system includes a transceiver, a matching network and an antenna. The matching network is operable to tune the antenna to the transceiver at both a first and second frequency. Accordingly, the matching network has a variable capacitor, an inductor and a second capacitor. The value of the variable capacitor is chosen to tune the antenna at the first frequency and the second frequency such that the system can be used to transmit and receive electromagnetic energy over two bandwidths. The values of the variable capacitor, the inductor, and the second capacitor are chosen to minimize the standing wave ratio of the system at both the first frequency and the second frequency.
