Abstract :
A thermal and electromagnetic model of a tunable hybrid mode dielectric double resonator is introduced and analyzed by the mode-matching technique. The temperature sensitivity of the structure is shown as a function of the spacing between the double resonators as well as the other resonator parameters. A simple optimization procedure is described, that enables the design of the resonator to have both wide tunability range and good thermal stability of its resonant frequency. The choice of the optimum parameters is based on parametric analysis, which reveals depicts all the relevant sensitivities to the designer. Experimental verification of the analytical result has been verified experimentally.<>
