ANTENNA MATCHING DEVICE AND METHOD FOR MULTI-BAND MOBILE COMMUNICATION TERMINAL

摘要

An antenna matching device, and more particularly, an antenna matching device and method for a multi-band mobile communication terminal are provided. The antenna matching device uses in a combined manner a tunable matching element (e.g., an RF MEMS variable capacitor) that operates mechanically in accordance with a mobile communication service area and a communication system (operating mode) with an electrically operable tunable matching element. Accordingly, a lifetime of the mechanically operable tunable matching element can be lengthened as long as possible.
