Abstract: A compact waveguide filter is provided to improve performance by arranging a plurality of waveguide resonators on an input port layer, a share resonator layer, and an output port layer, and electrically coupling the resonators with slots. A compact waveguide filter includes an input waveguide, an output waveguide, more than one first resonator, more than three second resonators, and more than one third resonator. The first resonator is arranged at the same layer with the input waveguide. The second resonators are arranged on a share resonator layer different from the layer where the input waveguide is arranged to face the input waveguide and the first resonator. The third resonators are arranged on the same layer with the output waveguide, and faces the second resonators arranged on the share resonator layer. The resonators on the same layer are electrically coupled with the resonators arranged on the opposite same layer through a first slot. The first resonators are electrically coupled with the second resonators of the share resonator layer, arranged at an opposite position, through a second slot. The third resonators are electrically coupled with the second resonators of the share resonator layer, arranged at an opposite position through a third slot. The input waveguide and the output waveguide are electrically coupled with one resonator arranged at the share resonator layer.

Abstract: A filter having a circular type cavity resonator using a plurality of via walls is provided to implement a miniaturization by reducing the number of a physical resonators by exciting the resonator with a double mode and arranging a resonator of a laminated shape. A filter having a circular type cavity resonator using a plurality of via walls intersected and laminated by a plurality of dielectric substrates and conductor substrates includes a cylindrical resonator, input and output slots(231,232), and input and output terminals(251,252). The cylindrical resonator forms a cylindrical cavity using the via walls to mutually connect the upper and lower conductor substrates with a first dielectric substrate by circularly arranging a plurality of cylindrical via holes(221) having a random radius in the first dielectric substrate among the plurality of dielectric substrates. The input and output slots excite a resonance formed in the cylindrical cavity of the via holes mode into the upper conductor substrate of the first dielectric substrate. The input and output terminals pump a signal inputted from the outside into the dielectric substrate placed to the upper layer of the conductor substrate into the input slot and the output slot.
