Dual-mode ring resonator filter is designed to have a relatively wide passband with a miniaturized circuit area. The miniaturization is achieved by folding the ring trace to a spiral configuration. The two degenerate modes are split up by an asymmetric inductive perturbation. As a result, the circuit area is only 29% of that of a conventional ring. The strong I/O coupling required by the wide passband...
A compact quadruple-mode ring resonator is proposed for synthesis of a quasi-elliptic bandpass filter. The resonator is composed of four half-wavelength rings connected to a single grounded via. For miniaturization, the ring areas are overlapped and the crossovers are implemented by short CPW sections in the ground plane. As a result, the resonator uses about 50% area of a conventional dual-mode ring...
This paper presents design of a bandpass filter using a novel dual-mode miniaturized octagonal patch resonator. Two slots in orthogonal position are cut on the patch to reduce the resonance frequency. Two circular holes connected by a slot are used to perturb the two degenerate modes of the patch. The proposed filter is 64% smaller compared to an octagonal patch without any slots.
A novel cross-coupled band-pass filter(BPF)based on the flute resonator is proposed in this paper. Due to the adoption of the same new configuration of coupling coefficient, the distance between the two loops is clearly shortened, which offers BPF an advantage of miniaturization. The configuration is characterized by a higher Q factor by introducing two transmission zeros in the transfer-function...
