They have been designed to be operated at 25 GHz which involve coplanar stripline input and output ports. The resonators have been simulated and analyzed using Ansoft HFSS. The research has been focused on the Quality factor of the coplanar stripline resonator. The conductor Q, box Q, and radiation Q of the resonators have been analyzed and calculated according to the substrate thickness & conductor width of the resonators. From these parameters, the loss factors of the coplanar stripline resonator have been investigated. The conducting Q of the coplanar stripline resonator has no relation with the thickness of dielectric substrate and increases as the conductor width increases. The box Q has no much relation with the thickness of substrate and the conductor width, which is above 2000. The radiation loss increases as the thickness of substrate and the conductor width increase. To decrease the raditation loss of the coplanar stripline resonator, a conductor backed coplanar stripline resonator has been proposed which has the unloaded Q of 170. 한국전기전자재료학회 마이크로파 가변 소자용 K-band Coplanar Stripline 공진기 설계 K-band Coplanar Stripline Resonator for Microwave Tunable Devices Article 2 전기전자재료학회논문지, v.18, no.6, pp.532 - 537 전기전자재료학회논문지 18 6 532 537 kci ART001089748 Coplanar stripline resonator Microwave Tunable Ferroelectric Quality factor.
