COMMUNICATION TERMINAL HAVING A PLURALITY OF MATCHING CIRCUIT AND METHOD OF CHOOSING THE MATCHING CIRCUIT OF THE TERMINAL

摘要

The present invention is a communication terminal including a matching circuit for performing impedance matching between the antenna and an optimized internal circuit and as more particularly relates to a matching circuit selection process is carried out in the communication terminal analyzes the frequency band of a communication signal having a plurality of matching circuits, and the communication terminal receiving the communication terminal, corresponding to the frequency band selecting a matching circuit, and the result will be varying with respect to the internal circuit to communicate signals to a system and method for providing the antenna with the best performing impedance matching. Communication terminal according to the present invention is to use a matching circuit for optimum efficiency in accordance with the communication signal transmitting and receiving antenna, seeking to improve the communication quality and life time of the battery is long jimyeo, also, the best antenna for a dual band may provide the antenna efficiency.
