Fractal - Shaped Microstrip End Coupled-Line Bandpass Filter

This paper presents a new compact fractal shape low insertion microstrip bandpass filter.The development of the frequency bands in microwave filter, play an important role in many RF or microwave applications. Filters are an essential part of wireless communications, networking ,radar ,imaging, and positioning systems. There has been a particularly marked growth in the cellular communications industry in recent years. This has contributed to both very demanding performance specifications for filters and the commercial pressures for low cost, high volume and quick delivery. Through an investigation into and a subsequent implementation of filter theory, the RF filter design of End Half-wavelength Resonators Bandpass Filters is simulate in this paper .The proposed filter is designed at center frequency of 2.45 GHz for 4.4 permittivity and having insertion loss greater than 30db for the range between 2.5 GHz to 4 GHz. The design and simulation are performed using 3D full wave electromagnetic simulator IE3D
