摘要
应用FDTD分析对数周期天线的时域辐射特性和馈电端反射特性 ,通过FFT得到频域辐射方向图及馈电端输入驻波比 ,计算结果和测试结果相当吻合 ,证明方法的有效性。
The finite difference time domain method (FDTD) is used to analyze the log periodic antenna. The radiation patterns and input VSWR in frequency domain of LPA are obtained by using FFT. The numerical results are compared with experimental results, and the comparison shows excellent agreement over a wide angle range.
