Title:
DOUBLE-LAYER PLANAR DUPLEXER FOR HIGHLY-INTEGRATED DUAL-MODE RECTANGULAR RESONATOR
Document Type and Number:
WIPO Patent Application WO/2019/184271
Kind Code:
A1
Abstract:
Disclosed is a double-layer planar duplexer for a highly-integrated dual-mode rectangular resonator, comprising a first dielectric plate and a second dielectric plate. The first dielectric plate and the second dielectric plate are arranged in a vertical direction, and a grounding plate is disposed between the first dielectric plate and the second dielectric plate. The grounding plate is provided with a slit, and a cylindrical member is provided at the slit. The first dielectric plate is provided with two rectangular microstrip structures and two input/output microstrip lines, the two rectangular microstrip structures are arranged in a left/right configuration and are connected, and the two input/output microstrip lines are respectively connected to one of the rectangular microstrip structures. The second dielectric plate is provided with a rectangular microstrip structure and an input/output microstrip line, and the input/output microstrip line is connected to the rectangular microstrip structure. One of the rectangular microstrip structures of the first dielectric plate is connected to the rectangular microstrip structure of the second dielectric plate via the cylindrical member. The present invention realizes a third-order planar microstrip duplexer. The third-order planar microstrip duplexer has the advantages of small volume, a simple structure, and easy processing, and has a wide application range.
