摘　　要：在微波暗室远场条件下,设计了一种利用线极化天线测量圆极化天线的方法。基于圆极化波的分解理论,利用线极化天线进行两次正交测量,所得结果通过公式换算,得到圆极化天线的方向性图和增益。通过多次对圆极化天线进行实际测试,验证了此方法的有效性,满足了实际应用的需要。In the microwave darkroom, a new method for measuring the circular polarization antennas is designed in far field by using the linear polarization antennas. Based on the decomposition theory of the circular polarization microwave, two orthogonal measurements for the linear polarization antennas can be made. By the conversion, it is easy to obtain the pattern and the gain of the circular polarization antennas. By measuring circular polarization antennas, the method is proved to be effective, thus meeting practical needs in engineering application.
