In this paper, the finite‐difference time‐domain method is used to analyze resonance processes in microstrip ring resonators, which are either edge or side coupled to the feedlines, in both the time and frequency domains. Standing waves established in resonant structures are visualized by simulating the spatial distribution of electromagnetic fields at resonant frequencies. The wave processes, which determine the resonance formation in edge‐ and side‐coupled resonators, are found to be significantly different in these two structures. © 2001 John Wiley & Sons, Inc.
