ABSTRACT:
A (radio frequency) RF reception system includes an RF receiver that demodulates an RF signal at a sequence of selected carrier frequencies. A frequency hop module, coupled to the RF receiver generates the sequence of selected carrier frequencies. A programmable antenna is tuned to each of the sequence of selected carrier frequencies to receive the RF signal via an antenna current.
