Abstract
A method () and devices for enhancing the performance of one or more antennas () is provided. A control circuit () assesses performance of an antenna () in a plurality of bands, such as a receive band and a transmit band. The control circuit () can then adjust an adjustable impedance matching circuit () coupled to the antenna () to improve the efficiency of the antenna () in the selected band and can adjust a resonance of the antenna () to further improve an efficiency of the antenna () in the selected band. Operating parameters for the antenna () can be selected from one or more multi-dimensional lookup tables () where the parameters are indexed both to a first operating band () and a second operating band ().
