摘要
带状线功分器结构中包含直角拐角和T型接头不连续性部分,会引入相应的不连续性传输损耗,传统的分析方法并没有考虑这部分损耗,导致分析结果不够准确.针对这个问题,提出了一种新颖的带状线功分器等效电路分析方法.在已获得的微带开路线不连续性等效电路模型及理论的基础上,提出了带状线功分器参考面T′区域的等效电路模型,并推导出了带状线功分器散射参数的计算公式.经实例验证发现,该等效电路分析法所得结果与仿真软件HFSS仿真结果吻合良好,带状线功分器散射参数的平均误差小于2%,这充分表明了该等效电路模型的正确性和有效性.
The striplines power divider structure contains right angles and T-junctions, which introduces the corresponding discontinuous transmission loss. The traditional analytical method is not accurate enough without considering this part of the loss. Aiming at this problem, this paper proposes a novel equivalent circuit analytical method of striplines power divider. We propose the equivalent circuit model of reference surface T′ region for striplines power divider based on our obtained equivalent circuit model and theory of micro-strip opening discontinuity, and we derive the formulas for calculating scattering parameters of striplines power divider. Through the practical example, we have found that the results of our equivalent circuit method are in good agreement with simulation software HFSS results, and the average error of scattering parameters for striplines power divider is less than 2%, showing that the equivalent circuit model presented in this article is valid and effective.
