FDTD/GPOF법을 이용한 Microstrip Line 불연속부의 해석에 관한 연구

A Study on the Analysis of Discontinuity of Microstrip Line Using FDTD/GPOF Method

In this paper, discontinuity parts in microstrip line with $\lambda$/4 open stub and one in crank type have been anlayzed by using FDTD(Finite-Difference Time-Domain) analysis method. The noise components, in this case, are occred at the discontinuites of the given microstrip lines, the complex poles were extracted by the analysis using GPOF (Generalized Pencil-of Function) method from electric field of time domain. It has, then, been found that the noise level and the noise frequency components included in signal could be derived.
