Abstract文章提出一种简单可行的高频电大尺寸天线辐射测量新方法。该方法基于天线形面光学精密测量,将形面分为多个区域,每个区域带入实际光学测试采样点数据,采用电磁场数值计算得到天线的辐射方向图.光学测试系统提供了足够高的测试精度可以满足微波、毫米波甚至太赫兹等频段天线的测试要求.该方法还可以解决超大型可展开天线测试以及模拟星载环境实验条件下天线辐射测试难题。
Other AbstractA simple but feasible method for the large and high frequency antenna patterns measurement is proposed in this paper. The computational electromagnetics method physical optics (PO) analysis based on targets data obtained by optical tests and finite element methods (FEM) is used to simulate the far field patterns and gains of the antenna. Because the optical testing systems have the accuracy well above the need for the microwave and terahertz (THz). Therefore the measurement data outline the real surface instead of ideal curve of the antenna. The PO simulations of currents integration of the real surface fitted by the sample spots represent the actual antenna radiation pattern. This method can also be used to evaluate the antenna radiation under special condition such as high and low temperature vacuum chamber test, THz antenna radiation test, deployable and inflatable antenna test (that are easily affected by gravity, wind and other environment etc.). The good agreement of the antenna patterns between direct test and simulations verifies the effectiveness and accuracy of this method.
