Apparatus and method for matching antenna in wireless terminal

摘要

Disclosed are apparatus and method for matching an antenna in a wireless terminal, which are tailored for easy control of impedance matching. A controller is configured to generate state information corresponding to states of the wireless terminal, and providing the state information to a Field Programmable Gate Array (FPGA) unit. The FPGA unit outputs an optimal Tunable Matching Network (TMN) adjustment value corresponding to the state information of the wireless terminal. State information may include operating bands / protocols and modes discerning particular environmental conditions impacting electric fields, such as a hand-held condition.
