摘要 文章通过FDTD算法对微带线直角拐角进行弧形切角研究,定量地得出弧形切角与反射特性S11之间的变化规律,并找到了最佳弧形切角;对不同宽高比W/h和不同相对介电常数rε的微带线进行FDTD模拟仿真,验证最佳切角的存在;将最佳切角与文献中传输性能最好的45°外斜切进行S11参数比较,前者S11平均优于后者约22 dB,这表明传输性能有很大的提高。 The arc-shaped cutting angle of the microstrip bend is investigated by the finite difference time domain（FDTD） method.The quantitative variation trend between the arc-shaped cutting angle and the reflection property S11 is given,and the optimal arc-shaped cutting angle is obtained.The simulations of the microstrip bends with different W/h ratio and relative dielectric constant εr are carried out to verify the optimal arc-shaped cutting angle.In view of the S11 parameter,the comparison is made between the obtained optimal arc-shaped cutting angle and the 45° external miter cutting which has the best transmission performance in related literature.The result shows that the S11 parameter of the former is better than that of the latter about 22 dB in average,which indicates the enhancement of the transmission performance.
