Abstract :
The slotted cylindrical ring (SCR) resonator has been recognised as a promising resonator for developing compact microwave filters. Using a new quasi-magneto-static finite-difference (QMSFD) method, the effects of geometrical parameters (i.e.: the resonator length, inner radius, gap width and wall thickness) on the unloaded Q-factor of this resonator, are investigated. Experimental and theoretical results of the Q-factor are compared. In addition, comparison is carried out against the published data.
