摘要

微波通信电路中会广泛应用共面波导（CPW）-共面波导以及共面波导-微带（MS）过渡结构。实际应用时，为了布线的方便，通过过孔连接的2段传输线并非始终处于直线上，而可能是任意夹角。仿真分析了经由过孔连接的2段传输线在不同夹角情况下的传播特性。仿真结果表明过渡结构的散射参数受两线夹角影响显著，总体而言，2种过渡结构的

|随夹角增大而增大，而|S

|则随夹角增大而减小。散射参数的变化趋势在夹角大于和小于90°时存在差异，在夹角为180°时更明显。此外，还比较并分析了CPW-CPW和CPW-MS结构传播特性的区别。

Abstract

Transmission lines connected to the two ends of via in coplanar waveguide (CPW) to CPW transition and/or CPW to microstrip (MS) transition are not always in line

but in arbitrary angle.The propagation characteristics of these structures are simulated and analyzed.The simulation results indicate that scatter parameters of the transition structures are affected by the angle of two transmission lines.In general

as angle increases

| of both transitions increases

while|S

| decreases.The change tendency of S-parameters is different when angle is more than or less than 90°

especially when angle is 180°.In addition

propagation characteristics of CPW-CPW and CPW-MS transitions are different

and the explanation is given.
