Novel periodically loaded multilayer resonators



In this paper novel 3D periodic multilayer structures are investigated in MIC technology, and a periodically loaded multilayer waveguide resonant structure is proposed. This is a very compact structure and still maintains simple fabrication process. The resonator is designed at 10 and 28 GHz. The simulated results of this resonator, which is obtained from commercial FEM software package HFSS, are confirmed by experimental results. The experiments are based on the same resonator structure, only at 10 GHz. By modifying the conventional waveguide resonator, with the proposed structure, a minimum 30% shorter resonator can be achieved, which is very important in filter applications. © 2002 Wiley Periodicals, Inc.
