摘要

本文利用时域有限差分(FDTD)方法，对微带到带过孔的cpw直角跃迁进行了全波分析。为了得到理想的回波损耗和插入损耗，进行了补偿。对时域结果进行傅里叶变换，得到了过渡的频率依赖特性。通过时域有限差分法得到了优化结构的数值结果，在30 ~ 100 GHz范围内，插入损耗优于−0.8 dB，回波损耗低于−12 dB。

Design and optimization of microstrip-to-CPW right-angled transition using finite difference time domain method

In this paper, we have presented full-wave analysis of the microstrip-to-CPW right-angled transition with via-hole by the finite difference time-domain (FDTD) method. Compensations have been done to get ideal return loss and insertion loss. Frequency dependent characteristics of the transition are obtained via Fourier transform of the time domain results. Numerical results of the optimized structure are obtained by FDTD, the insertion loss is better than −0.8 dB and return loss is lower than −12 dB from 30 to 100 GHz.
