Patent ID: 8860614

Claim:
A portable electronic device comprising: an earpiece speaker for generating audio signals from received electrical signals and for providing the audio signals as audible output; an antenna system having: a ground plane; a first element with a driven unbalanced antenna element resonating within a first predetermined frequency band for transmitting and receiving radio frequency (RF) signals modulated at one or more frequencies within the first predetermined frequency band; and a second element, located within an antenna volume of the first element, having: a driven antenna element, resonating within a second predetermined frequency band that does not overlap the first predetermined frequency band, for transmitting and receiving RF signals modulated at one or more frequencies within the second predetermined frequency band, wherein the second element creates a partial loop response within the antenna volume when connected to the ground plane while reducing electromagnetic fields of RF signals transmitted by the first element at locations proximate to the earpiece speaker, wherein the second element is non-resonating within the first predetermined frequency band; transceiver circuitry, coupled to the antenna system, having: transmitter circuitry for modulating signals for transmission from the antenna system as RF signals; and receiver circuitry for demodulating RF signals received by the antenna system to generate demodulated signals; and a controller, coupled to the transceiver circuitry and the earpiece speaker, for providing the received electrical signals to the earpiece speaker based on the demodulated signals.
