Claim Text:
1. A communication system comprising: an antenna; a matching network coupled to the antenna; a controller configured to control the matching network; and a look-up table coupled to the controller, the look-up table including characterization data according to frequency bands and conditions, wherein the controller is configured to refer to the look-up table to determine optimum impedance for a frequency band selected and under a condition detected during a time interval, and adjust the matching network to provide the optimum impedance, and wherein the controller and the look-up table are integrated on a chip; further characterized in that: the matching network comprises a plurality of switches, each switch coupled to one or more cells, wherein each cell comprises one or more capacitors, one or more inductors, or a combination of one or more capacitors and one or more inductors, and wherein the controller is configured to adjust the matching network by turning on one or more of the plurality of switches to provide the optimum impedance for the frequency band and the condition, based on a configuration of the cells coupled to the one or more of the plurality of switches that are turned on.
