提出了一种新型的单层4路功率分配器.它具有各端口理想的阻抗匹配和隔离特性及相邻输出端口间90°的相位差.它由3个环形电路组成,这些环形电路均由4段传输线段和1个电阻构成.通过经典的奇偶模分析技术,得到了该模型的闭式计算公式.为了验证该设计的有效性,将其在1 GHz工作频率上进行了两次建模仿真.仿真结果表明:提出的功率分配器可以有效地产生具有90°相位差的4路输出,具有很强的工程实用性和通用性.

A novel single-layer four-way power divider is proposed. It features perfect matching and isolation performance for every port and 90° phase difference between adjacent two outputs. It is constructed through the combination of three ring circuits which consist of four transmission lines sections and a resister. By the classical even-and odd-mode analysis technique,the closed-form design equations are derived. To demonstrate the validity of this design,two simulations are implemented at 1GHz. The results of simulation show that the proposed power divider can effectively produce four outputs with 90° phase differences and has a strong engineering practicality and generality.
