Abstract

A novel single-cavity triple-mode combined-type rectangular patch resonator (CRPR) is proposed in this paper, which is realized by integrating the rectangular patch structure with the rectangular substrate integrated waveguide (RSIW) structure. By cleverly designing the length-to-width ratios of both the RSIW structure and the patch structure, as well as the size ratio between them, the three higher-order modes of the CRPR can be resonance. Then, a highly selective bandpass filter (BPF) is realized through a special feeding structure. To demonstrate the method, an instance of a BPF is designed, synthesized, fabricated, and measured. The consistency of all results validates the effectiveness of the proposed design method. The proposed filter offers advantages such as relatively compact size, easy integration, and high selectivity.
