Method and system for optimizing impedance match in a mobile communication device

摘要

A mobile communication device has a number of selectable states, an antenna, and a communication circuit for transmitting and receiving communication signals. The mobile device also includes an impedance matching circuit having impedance matching networks. Each impedance matching network is associated with at least one of the selectable states of the mobile communication device and is configured to optimize the impedance match between the communication circuit and the antenna based on the selectable state of the mobile communication device with which the impedance matching network is associated. A switching network is included for coupling the antenna to the communication circuit together using one of the impedance matching networks based on a selected state of the mobile communication device.
