One implementation enables tuning a multi-band antenna such that two or more of the bands are tuned independently of one another, whereby tuning one band is decoupled from tuning another band. Some implementations include a multi-band tuning arrangement having first and second tunable two-terminal circuits. The first tunable two-terminal circuit has a low transmission impedance associated with a first frequency band, and a high transmission impedance associated with a second frequency band, the first tunable two-terminal circuit including a first control element to selectively adjust a first resonant frequency associated with the first frequency band. The second tunable two-terminal circuit having a high transmission impedance associated with the first frequency band, and a low transmission impedance associated with the second frequency band, the second tunable circuit including a second control element provided to adjust a second resonant frequency associated with the second frequency band. |
