摘要：
The finite-difference-time-domain (FDTD) method is applied to model some discontinuities that are present in C-band beam-forming networks. In particular a branch line coupler, a phase shifter, and a slope equalizer are modeled. A FDTD algorithm which makes use of nonuniform grids and a synthetic excitation, gives good results and saves computer resources. We achieve an efficient algorithm for analyzing BFN structures on a personal computer Numerical results ave given for the scattering parameters of three devices in 3.4-4.2-GHz band.
