| 摘 要： | 复合左右手传输线的提出在无线通讯领域将有很大的应用前景,也为微波传输线和微波元件的设计提供了一种新思路.根据复合左右手传输线的相位特性及频带展宽原理设计了一个90°移相器,该移相器理论上可以实现L波段从f_1到f_2的90°移相.相对带宽为31%,工作频带内的绝对误差在±3°以内.仿真结果表明,基于复合左右手传输线的90°移相器能够实现宽带内的移相,且效果比较明显.实际电路也比较吻合仿真电路,达到理想的要求.

| Abstract: | The compound left-right transmission line has a great application prospect in the domaine of radio communication,provides also a new thingking for microwave transmissien line and microwave components.The authors designed a 90° phase shifter according to the phase characteristics and band spread principle of left-righ transmission line.The phase shifter can realize 90° phase shift from f_1 to f_2 in L ban in theory,its relative bandwidth is 31%.absolute erros in operating frequency band is within ±3°.The simulated results indicate that the phase shifter can realize the phase shift within wideband,and the effect is obvious. |
