摘要
本文从实际工程应用出发,结合电磁场理论,系统的阐述了平面近场中极化偏差的修正方法。并基于椭圆极化波的分解理论,提出了利用椭圆极化长轴倾角修正因测试探头和待测天线的极化偏差造成的测试误差。实验结果验证了该方法的有效性。
Starting from practical engineering application, a method of correcting polarization deviation in planar near filed is addressed by combining with the electromagnetic theory. Based on elliptical polarization wave decomposition theory, the test error caused by deviation of polarization of the test probe and antenna under test is corrected by using tilt angle of long axis of elliptical polarization. The experiment results validate effectiveness of the proposed method.
