Design of a Quad section triangular quasi fractal bandpass filter

The Quad section triangular quasi fractal bandpass filter operating around 1.5 GHz frequency was designed in this thesis. It was very expensive to build a large size filter and difficult to carry, so there was a technique called "Filter design using fractals" which reduces the size of the filter and the cost. As there was a demand for miniaturization of RF and microwave filters, so the fractal resonators were completely analyzed and the outline for the miniaturized fractal filters was created. Fractal resonators were small compared to the conventional planar resonators. As the number of iterations increases, resonator size decreases and quality factor increases. Miniaturized fractal filter designs depends on the symmetrical or asymmetrical pseudo elliptic characteristics of an inline model and electromagnetic simulator was used by coupling factor simulations
