摘要
介绍了一种新型后馈式宽带脊波导到同轴转换接头的分析设计方法,该方法采用模式转换和阻抗匹配的思想,通过切比雪夫型阶梯阻抗匹配枝节实现高低阻抗之间的过渡,并在脊波导和同轴线之间添加模式变换段改进接头的性能。详细分析了设计原理,给出了设计步骤,并用全波仿真软件进行了仿真验证。按照该方法设计并制作的650双脊波导到同轴宽带转换器,经测试在6.5～18 GHz的频率范围内性能良好,其技术性能指标优于已知的同类产品。
A new method to design wideband transition from double-ridge waveguide to coaxial line is introduced in this investigation. The proposed design of the transition is based on the theory of mode conversion and impedance matching. The Chebyshev type of impedance matching network is employed, a new mode converter structure between the coaxial line and the ridge waveguide has been used for design. The characteristics of the transition in microwave frequencies are analyzed and simulated by full-wave analysis software. According to this ideal, a couple of transitions have been finished. The predicted superduper performance has been confirmed experimentally in the range of 6.5- 18 GHz.
