微带线不连续性补偿方法的HFSS仿真分析

摘要

微带电路元件都包含有不连续性,从等效电路上相当于引入了电抗元件,必然对电路产生影响.为了研究微带线转弯对其电性能的影响,采用Ansoft HFSS软件仿真的方法,定量地分析微带线不同类型不连续性补偿方法的优缺点.通过仿真发现,a＝1.6w削角弯头的回波损耗和插入损耗最优,可以用于小尺寸的转弯；R＝3w圆形扫掠弯头的回波损耗和插入损耗也比较良好,可以用于大尺寸的转弯.%The components of microstrip circuit are discontinuous, the reactance components introduced in the equivalent circuit have an effect on microstrip circuit. To research the electrical property of microstrip bend, making use of Ansoft HFSS software and analyzing the advantages and disadvantages of discontinuity compensation methods of different microstrip bend. From the simulation result, a conclusion show that return loss and insertion loss of mitered bend are the best when a= 1. 6ti> and it can be used for small size turning, the return loss and insertion loss of Swept bend are satisfactory for large size turning when R=3 w.
