Circular microstrip resonators on gyrotropic substrates
Abstract
Circular resonators using an isotropic substrate, such as Al2O3 ceramics or plastics, can be employed as simple filter elements. Circular resonators with anisotropic premagnetized ferrite substrate form the basis of 3-gate junction circulators. Accurate information regarding the electromagnetic behavior of the circular resonator is needed for the exact dimensioning of a circulator. Precise data regarding the resonance frequencies and the field distribution can only be obtained if all relevant effects are considered in the analysis. A suitable analysis method is discussed, taking into account the anisotropy of the material as well as the radiation modes.
