本文提出了一种利用多普勒测频技术测量天线相位特性的新方法。利用这种方法，被测天线绕通过其几何中心的轴以f/sub sp/的速率旋转，并且天线的相位特性从从天线发射的无线电波的多普勒频率的时间变化期间的f/sub sp/的谐波分量计算。利用这一点，我们得到了三维相位特性的贴片天线的均方根误差约为0.5/spl度/，并通过实验结果证实了其功效。
This paper reports on a new method of measuring the phase characteristics of an antenna using the Doppler frequency measurement technique. With this method, the antenna being tested is rotated at a rate of f/sub sp/ around an axis through its geometrical center, and the phase characteristics of the antenna are calculated from the harmonic components of f/sub sp/ during time variations in the Doppler frequency of radio waves emitted from the antenna. Using this, we obtained three-dimensional phase characteristics of a patch antenna with a root-mean-square error of about 0.5/spl deg/, and confirmed its efficacy through experimental results.
