ABSTRACT:
A programmable antenna includes a fixed antenna element and a programmable antenna element that is tunable to one of a plurality of resonant frequencies in response to at least one antenna control signal. A programmable impedance matching network is tunable in response to at least one matching network control signal, to provide a substantially constant load impedance. A control module generates the antenna control signals and the matching network control signals, in response to a frequency selection signal.
