Waveguide synthesis network with ET structure

The invention is applicable to the technical field of communication, and provides a waveguide synthetic network with an ET structure, which comprises a main waveguide, two branch waveguides and four tail end branch waveguides, the two branch waveguides are symmetrically arranged at one end of the main waveguide, and the end, far away from the main waveguide, of each branch waveguide is provided with two tail end branch waveguides; 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 synthetic network of the ET structure provided by the embodiment of the invention, the microstrip metal probe structure isadded on the ET branch s
