宽带脊波导魔T的设计
|
摘要
介绍了一种宽带脊波导魔T,该模型通过两根金属棒将魔T的H臂的上脊与E臂的双脊相连,采用阻抗变换的思想,通过切比雪夫阶梯阻抗枝节变换实现高低阻抗之间的过渡,并在ET接头和HT接头的交界处添加金属匹配块来改进接头的过渡匹配。文中分析了宽带脊波导魔T的设计原理,采用WRD650脊波导设计,利用全三维仿真软件进行了仿真验证,在10 GHz～18 GHz的频率范围内得到较好的性能指标。
A wideband double-ridge waveguide magic Tee is introduced. The proposed model employing two rods for connecting the upper ridge of the H-arm of magic Tee to both ridge of the E-arm of magic Tee. The use of a impedance matching network and a matching metal block to achieve the match of E-T junction and H-T junction has realized super performance in the range of 10 GHz ～ 18 GHz. The characters of the model are analyzed and simulated by full-wave analysis software.
