Apparatus and method for diagnosing antennas using switches

摘要

An apparatus and method for diagnosing antennas using switches, wherein a system is configured in such a manner that a plurality of switches determine a data flow of a signal for test. Therefore, the antenna diagnosing apparatus can be so simplified in circuitry construction that it can be easy to manufacture at low cost. Further, the antenna diagnosing apparatus can accurately measure standing wave ratios of the antennas without being subject to any error, so as to accurately diagnose the performance of the antennas.
