摘要: The present invention provides an antenna coupling preventing system and method capable of minimizing coupling between a GPS antenna and a CDMA antenna. The system comprises first and second antennas for receiving first and second RF signals of first and second frequencies, respectively; a mobile switch for measuring performance characteristics of the second antenna; and a switch circuit connected between the second antenna and the mobile switch for controlling flow of the first RF signal to the second antenna.
