Abstract

A 3D finite difference time domain (FDTD) simulation software was developed. The visual electric field distribution and the voltage signals in time domain of the microstrip bends with different miters are obtained based on the electromagnetic field information provided by FDTD simulation. The relation of the reflection parameter versus miter size and frequency by curve fitting reveals that the optimal cut size has the decreasing trend to 0.5 with the frequencies increasing. The optimal miter scheme is practical when the operation frequency has to be taken into account.
