摘要:

根据带状线理论,设计了一种新型的带状线定向耦合器。通过将耦合带状线分段处理,根据每段带状线的耦合度,合理地设计每段耦合带状线的物理参数,拓宽了耦合器的工作频带。同时通过优化仿真,以补偿耦合器奇模与偶模之间相速度的差异,并抵消不连续性所带来的寄生参数的影响,从而提高定向耦合器的方向性。在设计过程中,借助Ansoft Designer软件进行初步优化仿真,最终电路版图以AutoCad格式导入到HFSS中进行进一步验证。

Abstract:

A new stripline directional coupler is designed by putting a coupled stripline segmentation processing with physical parameters for each section of the stripline reasonably designed to broaden the working band of coupler.Simulation optimization is performed to compensate for the coupler phase velocity difference between odd and even dies and to offset the influence of the parasitic parameters of the discontinuity for better directivity of the directional coupler.The software Ansoft Designer is employed for initial simulation optimization,and the resulting circuit layout is input in AutoCad format into the HFSS for further verification.

Key words: stripline;coupler;ultra wideband
