Abstract
A tunable antenna module for a mobile device includes an antenna, a frequency-division circuit and one or more impedance-tuning circuits. The frequency-division circuit is coupled to a radiator of the antenna for forming one or more signal paths for one or more of component frequencies of a radio-frequency signal of the antenna. One or more the impedance-tuning circuits are coupled to the frequency-division circuit for tuning an impedance of the antenna at one or more of the component frequencies of the radio-frequency signal.
