| Description | This research aims to design a microwave filter by studying and simulating the discontinuity in the waveguide. We suggest a filter consists of three waveguides connected to each other and different dimensions. Changing the dimensions of the waveguide will change the conditions of propagation of microwaves and in our suggested filter we have two discontinuity regions affecting on the modes of frequencies propagated through the waveguide. We apply Galerkin method for studying the discontinuity region in the waveguide. We have modelled all the calculations and results by Matlab program so we could simulate the filter and study and the effect of changing the dimensions on the propagated modes, calculate [Z] matrix and scattering matrix [S] for the designed filter and find the relation between transmission coefficient (T), reflection coefficient (R) and the frequency (f) to determine the properties of the designed filter. |
