Zusammenfassung:The invention discloses a hybrid electromagnetic coupling duplexer based on a half-mode substrate integrated waveguide (HMSIW). The diplexer comprises a dielectric substrate, a metal grounding layer on the lower surface of the dielectric substrate, and an upper metal layer on the upper surface of the dielectric substrate. The upper metal layer comprises first to third ports which are an input port, a low-frequency band branch filter output port, and a high-frequency band branch filter output port respectively. The upper metal layer of the dielectric substrate is provided with a low-pass filter and a high-pass filter which are connected in parallel to form the hybrid electromagnetic coupling duplexer. Each branch filter is formed by a half-mode structure connected with a pair of symmetrical open-circuit branch wire. The end of each pair of open-circuit branch wire is provided with parallel open-circuit coupling lines. A column of metalized through holes are arranged between the low-pass filter and the high-pas
