| 摘 要： | 基于尺寸原因定向耦合器在微波电路中的应用受到限制,采用接终端开路短截线的方法使四分之一波长的微带线变成T型结构,并进一步对短截线等效成为十字型微带线的方法,设计出小型化的定向耦合器。通过使用ADS软件进行仿真,设计的定向耦合器各项性能指标符合要求,面积为常规微带分支线定向耦合器的36%。

| Abstract: | Directional coupler in microwave technology is widely used but the size limits its scope of application. In the article change a quarter wavelength microstrip line into a T-structure by connecting Open-end stub and then the stub is equivalent to a cross-shaped microstrip line. So we get the miniaturized microstrip branch-line coupler. Simulating the microstrip branch-line coupler by software ADS, performance indicators meet the requirements. The size of miniaturized microstrip branch-line coupler is 36% of that traditional microstrip branch-line coupler. |
