|
摘要
文章介绍了一种基于波导-鳍线-微带线过渡的4路功率合成器结构,并通过Ansoft HFSS电磁仿真软件对其进行了仿真分析和优化设计。在整个X波段(8GHz～12GHz)内,功率合成器的插入损耗小于0.25d B,回波损耗大于-15d B,且通过加载微带扇形结构使同一平面上端口的隔离度大于8.5d B。结果表明,此结构在实现微波功率合成方面具有一定的应用前景。
A four-way power combiner based on waveguide-finline-microstrip transition is proposed and it was made a simulated analysis and optimized by Ansoft HFSS electromagnetic simulation software. The isolation loss of the power combiner is less than0.25 dB in the entire X-band(8 GHz～12 GHz), the return loss is greater than-15 dB, and the isolation of ports on the same plane is greater than 8.5 dB by loading a microstrip sector structure. The simulation results show that this structure has a certain application prospect in microwave power combiner.
