【Abstract】 In this paper,varactor tufted bandpass filters of microstrip ring- resonators are studied.The Resonance characteristics of ring-resona- tor and the coupling characteristics between two ring-resonators are obtained.We have made a varactor tuned bandpass filter and got a good agreement between the measured and theoretical results.更多还原
