Patent ID: 7831229

Claim:
FM receiver including an FM antenna that receives continuous wavelength signals, the FM receiver coupled to the FM antenna and operable to alter a center frequency of a gain profile of the FM antenna, the FM receiver comprises: a low noise amplifier module coupled to amplify the continuous wavelength signal to produce an amplified RF signal therefrom; a down conversion module coupled to mix the amplified RF signal with a local oscillation to produce an information signal; a filter module coupled to filter the information signal to produce a filtered information signal; a demodulation module coupled to capture audio information from the filtered information signal; a signal monitoring module coupled to monitor FM signal quality of a received continuous wavelength signal, the signal monitoring module producing a signal quality indication therefrom; and an antenna control module to produce a signal value based upon the signal quality indication, wherein the signal value operates to alter the center frequency of the gain profile of the FM antenna, the antenna control module includes: a plurality of lumped tuning elements; and a plurality of switches coupled to the plurality of lumped tuning elements, wherein positions of the plurality of switches based upon the signal value operates to affect an impedance of the plurality of lumped tuning elements to produce an impedance adjustment value that corresponds to the signal value to alter the center frequency of a gain profile of the FM antenna.
