Abstract
A thin film resonator which combines a microstrip resonator structure and a coplanar resonator structure to form an integrated resonator structure. The resonant frequency of this resonator structure is independent of the substrate thickness within a certain thickness range. This resonator structure also has a very economical size, as compared to other existing resonator designs. Different coupling configurations between the resonators are shown with the resulting coupling coefficients. Also a two-pole, four-pole and an eight-pole filter are designed using the thin film resonator and the insertion loss and return loss characteristics for various filters are shown.
