Patent ID: 8064495

Claim:
A (radio frequency) RF reception system comprising: a frequency hop module that generates a sequence of selected carrier frequencies; a programmable antenna, coupled to the frequency hop module, that is tuned to each of the sequence of selected carrier frequencies and that receives an RF signal having the sequence of selected carrier frequencies via an antenna current, wherein the programmable antenna includes: a fixed antenna element; a programmable antenna element, coupled to the fixed antenna element, that is tunable to each of the sequence of selected carrier frequencies in response to at least one antenna control signal; a control module, coupled to the programmable antenna element, that generates the at least one antenna control signal and generates a plurality of matching network control signals in response to the sequence of selected carrier frequencies; and a programmable impedance matching network, coupled to the programmable antenna element and the control module, that includes a plurality of adjustable reactive network elements that are tunable in response in response to the corresponding plurality of matching network control signals, to provide a substantially constant load impedance; an RF receiver, coupled to the frequency hop module and the programmable antenna, that demodulates the RF signal.
