无线局域网设备天线性能测试

摘要

由于无线局域网设备为同频时分设备,其上下行链路共用同一频率,因此传统的异频双工设备天线性能测试方法对其不适用。本文介绍了无线局域网设备天线性能的测试标准,给出了被测终端的设置要求,介绍了适用于无线局域网设备的天线性能测试方法。该方法符合标准要求,且测试精度高,不确定度低。%Because of-using the same frequency for uplink and downlink communication, traditional an- tenna performance evaluation method for different frequency duplex equipment is not applicable to device supporting wireless local area network. An- tenna performance test specification for WLAN de- vice and test configuration of equipment under test are introduced. Antenna performance test methods applying to WLAN device is introduced which comply with test specification and have high test accuracy and low measurement uncertainty.
