Abstract

Characterization of a whispering gallery dielectric resonator coupled to two parallel microstrip lines F. Nigon, D. Cros, M. Aubourg, P. Guillon 123 Avenue A. Thomas, 87060 Limoges Cedex, France ABSTRACT This paper presents a general method to characterize a dielectric resonator coupled to two parallel microstrip lines. The scattering parameters of such a structure are calculated using the Finite Element Method calculation and the coupled transmission lines properties. This method is applied here in the case of a dielectric resonator excited on a Whispering Gallery mode. Thus, the structure is used as a two ways power combiner . In order to optimize the combiner efficiency, the optimum spacings between the resonator and each microstrip line are computed using an equivalent model. The results given by this method of characterization are in good agreement with the measurements. INTRODUCTION Since dielectric resonators (D.R.) coupled to microstri
