摘　　要：物联网设备天线有源性能测试项目主要包括总全向辐射功率(TIRP)和总全向辐射灵敏度(TIRS)测试。传统的天线有源测试方法需要测试大量角度的EIS和EIRP,测试效率低下。为了缩短天线有源测试时间、提升测试效率,介绍了一种基于天线互易性原理的天线性能有源测试方法,并选取一款LTE-Cat1物联网终端实际验证了所述测试方法的实际效果,结果表明,该方法可以避免现有方法存在的弊端,缩短测试时间,提升测试效率,具有工程实用价值。The antenna active performance test items of IoT devices mainly include total omnidirectional radiated power(TIRP)test and total omnidirectional radiated sensitivity(TIRS)test.Traditional antenna active testing methods need to test a large number of angles of EIS and EIRP,which is inefficient.In order to shorten the antenna active test time and improve the test efficiency,an antenna performance active test method based on the principle of antenna reciprocity is introduced,and an LTE-Cat1 IoT terminal is selected to verify the actual effect of the test method.The results show that the method can avoid the drawbacks of the existing methods,shorten the test time and increase the test efficiency,which has engineering application value.
