Abstract
A communication system is provided, including 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 includes characterization data according to frequency bands and conditions. The controller is configured to refer to the look-up table to determine optimum impedance for a frequency band selected under a condition detected during a time interval, and adjust the matching network to provide the optimum impedance.
Claims24
A communication system comprising:
- an antenna;
- a matching network coupled to the antenna;
- a controller configured to control the matching network;
- a look-up table, 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 the controller further configured to adjust the matching network to provide the optimum impedance;
- further characterized in that the communication system further comprises:
- one or more sensors configured to detect the condition during the time interval, wherein
- the controller receives information on the condition from the one or more sensors and uses the information upon referring to the look-up table.
(canceled)
A method for impedance matching of a communication system including an antenna and a matching network, comprising:
- obtaining data associated with antenna characteristics for frequency bands and conditions;
- storing the data in a look-up table according to the frequency bands and the conditions;
- adjusting the matching network with reference to the data in the look-up table to provide optimum impedance for a frequency band selected and under a condition detected during a time interval;
- and
- detecting the condition during the time interval by using one or more sensors.
