Abstract :
The purpose of this paper is to investigate a novel class of high-Q combline resonators for application at RF and microwave frequencies. The novel combline resonator with its inner rod of periodic structure not only achieves high-Q-factor but also retains all the merits of the conventional combline resonator. In this paper, the performances of a conventional combline resonator are compared with those of the novel combline resonator. The numerical results with respect to the Q-factor were accurately determined. A quarter-cut dielectric resonator is measured and compared for optimising resonator structures
