Waveguide synthesis network with ET structure

The invention is applicable to the technical field of communication, and provides a waveguide synthesis network of an ET structure. The network comprises a main waveguide, two branch waveguides and four tail end branch waveguides, wherein the two branch waveguides are symmetrically arranged at one end of the main waveguide, and two tail end branch waveguides are arranged at one end, far away fromthe main waveguide, of each branch waveguide; a first microstrip metal probe is arranged at one end, close to the two branch waveguides, of the main waveguide, and the other end of the first microstrip metal probe is connected with a load resistor; a second microstrip metal probe is arranged at one end, close to the tail end branch waveguide, of each branch waveguide, and the other end of each second microstrip metal probe is connected with a load resistor. According to the waveguide synthesis network with the ET structure provided by the embodiment of the invention, the microstrip metal probestructure is added to the
