Abstract

The present invention discloses a dual-passband power dividing filter adopting single-layer circular patch. The filter comprises a dielectric substrate, a metal grounding plate is arranged on the lower surface of the dielectric substrate, and an input port feeder line, a first output port feeder line, a second output port feeder line and the circular patch are arranged on the upper surface of the dielectric substrate. The circular patch is located at the middle position of the upper surface of the dielectric substrate, the input port feeder line is tangentially connected with the semicircle of the circular patch, and the first output port feeder line and the second output port feeder line are tangentially connected with the other semicircle of the circular patch respectively; and the circular patch is provided with a magnetic field perturbation component, an electric field perturbation component, an isolation component and a fifth metal through hole, and the fifth metal through hole is located at the circle center of the circular patch. The dual-passband power dividing filter is compact in structure, small in insertion loss, good in isolation degree and suitable for a modern wireless communication system.

Description

technical field [0001] The invention relates to the technical field of microwave passive devices, in particular to a double-passband power division filter using a single-layer circular patch. Background technique [0002] Modern wireless communication systems require compact and high performance power division bandpass filters. With the development of multi-band and multi-standard modern wireless communication systems, the demand for multi-band microwave components is increasing. Among them, dual-band filter power dividers (DB-FPDs) have been receiving much attention. In the past few years, researchers in related research directions have made many efforts to develop them. In order to realize the functions that people need, in literature 1 [P.Wen, Z.W.Ma, H.W.Liu, S.S.Zhu, B.P.Ren, Y.Song, X.L.Wang, M.Ohira, "Dual-band filtering power divider using dual-resonance resonators with ultrawide stopband and good isolation.”IEEEMicrow.Wireless Compon.Lett.,vol.29,no.2,pp.101-103,...
