Abstract :
By replacing the inner conductor of the conventional combline resonator with a high /spl epsiv//sub r/ dielectric rod, higher unloaded Q of the resonator can be expected. Resonant frequency, unloaded Q and coupling coefficient of the resonator are obtained by rigorous mode matching method. An 8-pole elliptic function dielectric combline resonator filter is designed. Good frequency responses are obtained.
