Abstract

The invention discloses a double-passband balance filter adopting a double-layer circular patch, which comprises an upper dielectric substrate and a lower dielectric substrate, wherein a metal grounding plate is arranged between the upper dielectric substrate and the lower dielectric substrate, a top metal plate of the upper dielectric substrate is provided with a top circular patch, a first inputport feeder line, a second input port feeder line, a top first slot line and a top second slot line, a bottom metal plate of the lower layer dielectric substrate is provided with a bottom circular patch, a first output port feeder line, a second input port feeder line, a bottom first slot line and a bottom second slot line, and the metal grounding plate is provided with a grounding plate first slot line and a grounding plate second slot line. One end of the input port feeder extends to the side edge of the dielectric substrate, and the other end of the input port feeder is tangent to the circular patch.

Description

technical field [0001] The invention relates to the technical field of microwave passive devices, in particular to a dual-passband balanced filter using double-layer circular patches. Background technique [0002] Modern wireless communication systems require compact and high performance balanced bandpass filters. In recent years, multi-passband filters have attracted extensive research interest because of the diversity of operating frequencies in the same device, and because many RF devices are robust to electromagnetic interference and common-mode noise, they need The addition of the balance function, so the integration of dual passband, balance and bandpass filtering can greatly reduce the number of microwave components used in the same system. However, multi-passband balanced filters with promising applications have not been extensively studied. In order to realize the balance function, in literature 2 [W.Feng, W.Che, and Q.Xue, "New Balance—Applications for Dual-Mode ...
