摘要
首先应用FDTD对毫米波多波束波导裂缝馈源进行分析计算 ,讨论了馈电波导及辐射缝结构对馈源方向图的影响 ,然后用物理光学法由抛物面上电流计算抛物面天线方向图 ,方向图的计算结果和测试结果相当吻合 ,这证明方法的有效性。
The finite difference time domain method (FDTD) is used to analyze the slots feed of paraboloidal reflector antenna The effects of feed waveguide and shape of radiation slots on feed patterns are also discussed The paraboloidal reflector antenna patterns are presented by using physical optics, and the numerical results are compared with experimental results, and the comparison shows excellent agreement over a wide angle
