Various Shapes of 3 D Resonators Pass-Band Filters

The integral equations technique based on a three dimensional finite element method is applied as a quick and accurate analysis tool for the design of microwave passband filters. A three resonator H-plane bandpass filters with the various shapes of cavities and the irises are analyzed with this method in a single step and for only one mode, take into account all the electromagnetic effects. Consequently, it consumes less memory and CPU time.
We propose also to study the same filters filled by homogeneous high dielectric material (ετ = 9.6) for Both resonator and coupling section.
All these numerical results have been validated through a comparison with the results available in the scientific literature.
