Abstract
A microstrip ring resonator that uses quarter-wave coupled lines for input and output coupling is presented. The ring exhibits a double resonance due to an asymmetry in the topology of the structure. When the asymmetry is removed a single resonant peak is observed. The insertion loss of the ring is 6 dB and its quality factor is 64
