| 摘 要： | 基于微波奇偶模理论、叠加原理和阻抗匹配理论分析设计了3-dB功率分配器的结构参数，使用高频电磁场仿真软件HFSS进行结构仿真和参数优化，得到了最优结果：输入端口1的反射损耗RL=-41.42dB；1和4端口的隔离度Iso=-44.86dB；输出端口2、3的功分度为-3.02 dB和-3.01 dB；输入驻波比VSWR=1.017。

| Abstract: | The even-odd mode theory, wave superposition and impedance matching are used to design the 3-dB power splitter, then the structure and the parameters of the power splitter are simulated by HFSS cord. Finally the optimistic results are acquired: reflection loss in input port 1 is -41.42dB; isolation between the port1 and 4 is -44.86dB; power splitting in output port 2, 3 are -3.02 dB, -3.01 dB；input VSWR is 1.017. |
