Based on the analysis approach of the two dimensional finite element, an analysis method of 4 port E plane branch waveguide couplers is presented in this paper. By means of the proposed method, a software is developed and successfully applied in the 'Integrated System for Microwave Module Design and Manufacturing(ISMMDM)'. Comparing the computed results of a 4 port 4.9dB E plane 5 branch waveguide coupler with the experimental results and the simulated results of HFSS(a high frequency structure simulator software based on 3D finite element method) shows that the analysis approach and the software realization are verified accurately and efficiently. This method can be widely used in the analysis of similar microwave devices.
