1. A programmable antenna comprising:
- an antenna that has an antenna current includes;
a fixed antenna element; and
a programmable antenna element, coupled to the fixed antenna element, that is tunable to one of a plurality of resonant frequencies in response to at least one antenna control signal; and
a programmable impedance matching network, coupled to the antenna, that includes a plurality of adjustable reactive network elements that are tunable in response in response to a corresponding plurality of matching network control signals, to provide a substantially constant load impedance; and
a control module, coupled to the programmable antenna element and the programmable impedance matching network, that generates the at least one antenna control signal and the plurality of matching network control signal, in response to a frequency selection signal.

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.
