无线产品OTA空间射频性能测试方法改进
Improved Test Method for RF Products Over the Air Performance
摘要 介绍了无线产品OTA空间射频的取点方法,TRP、TIS测试方法的准确性和效率很大程度上取决于测试点的选取。均匀取点测试方法在测试误差、测试点数及路径规划等方面比等角度取点方法更有优势。最后用仿真和试验测试验证了均匀取点测试方法的准确性。

Abstract The usual selection method of measuring point in OTA test is introduced. The
accuracy and time of OTA test is mainly determined by the number and the distribution
of the measurement points on the sphere of the DUT.We propose an evenly distributed
sampling method, which is more accurate and efficient to evaluate TRP and TIS than
the evenly angle sampling methods.And also give the test result to support the evenly
distributed sampling method.
Keywords OTA (over the air) test;TRP (total radiated power); TIS (total isotropic
sensitivity)
