Abstract :
A rigorous method for analysis of coupled dielectric quarter wavelength combline resonators is presented. The resonant frequencies and coupling coefficients of the resonators coupled by different coupling structures are investigated. A filter design technique based on the results of numerical analysis is described. A slot coupled filter and a monoblock elliptic function filter are designed. Excellent experimental results verify the theory
