Abstract :
Two distinct but very close resonant peaks of a ring resonator side coupled to microstrip line are experimentally found to be due to odd- and even-mode coupling. Introducing proper breaks in the ring maintained the resonance characteristic of one mode while shifting the other peak away from the region of interest
