碩士 === 國立彰化師範大學 === 工業科技教育研究所 === 82 === The objective of this research is to apply an electric field integral equation (EFIE) method for the analysis of microstrip resonators of arbitrary shape. The EFIE method is based on a field equivalence principle. The microstrip patch is replaced with the induced equivalent current source, the integral equation then expresses the electric field in terms of this current source integrated into a Green's function for the layered microstrip structure. Effects of boundary conditions on the behavior of the fields are incorporated in their full generality in the Green's function. For numerical computation of the resonant frequency and other qiantities, we follow Galerkin's method of moments, and current functions obtained from cavity model are used for expansion and testing. Results in the form of resonant frequency and current distributions are obtained, and are compared to those available in the literature. Results from this research can be used as useful reference for the design work. Also, the approach addressed in this thesis can be used for analyses of other novel microstrip devices.
