We present a novel microstrip ring resonator (MRR) excited by a transmission line. The MRR is capable of controlling signal propagation along the peripheral of the resonator such that it is able to prohibit signal propagation within the vicinity of the narrow band closed to the target resonant, so long the magnetic component of the electromagnetic (EM) field is polarized with respect to the ring axis. The magnetic fields invariably induced current at the MRR loops via the distributed capacitance between the rings at target frequency, to ensure the frequency-selective characteristics. The selectivity behaviour is dependent on the degree of the induced current in the ring loop at the frequency under consideration can be explained by the induced current loops in the rings at resonance. We therefore investigate the electrodynamics propagation mechanism of this novel MRR to leverage on its frequency-selective behaviour to evolve miniaturized passive resonators.
