تاثير زاوية ورود الامواج في المرشح التجزيئي الميكروي

Fractal filters have been studied before, and the effect of fractal parameters on the design of filter has been discussed for normal incident. In this paper, we propose a study for the effect of the angle of incidence on fractal filters. We choose a Cantor bar as an example of fractals. Firstly, we investigate its reflection and transmission coefficients when an electromagnetic wave obliquely occurs. Secondly, we draw twist plots which can be help design selective fractal filters. Finally, we demonstrate that the little deviation of the wave incident angle gives very small changes in terms of resonant frequency and bandwidth of fractal filters.
