Novel substrate integrated waveguide power divider/combiner

Abstract

The invention discloses a novel substrate integrated waveguide power divider / combiner and belongs to the field of microwave devices. The novel substrate integrated waveguide power divider / combiner comprises a single-layer substrate, a trapezoidal microstrip-substrate integrated waveguide transition structure arranged on the single-layer substrate, and an input / output port, wherein the single-layersubstrate is provided with a five-port narrow-walled short slit coupling unit and a lumped resistance loading matched load; two ends of the five-port narrow-walled short slit coupling unit are sequentially connected with the trapezoidal microstrip-substrate integrated waveguide transition structure and the input / output port; one end of the five-port narrow-walled short slit coupling unit is connected with the lumped resistance loading matched load; by increasing two isolated ports, perfect matching of five ports and high isolation of two branch ports can be realized, the lumped resistance loading matched load is connected to the isolated ports so as to realize broadband, the problem that the conventional traditional waveguide power divider and a substrate integrated waveguide power divider cannot simultaneously take the broadband and high isolation into account is solved, and the effect of broadening the bandwidth while ensuring the isolation is achieved.
