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
