However, meeting these requirements comes with many challenges, namely increased design complexity, system size, its fabrication and cost effectiveness. Accordingly, paper aims to design a reconfigurable microstrip filter in terms of their geometrical structures and operational performances. A Reconfigured Compact Minkowski Fractal Microstrip Filter with inverted C shape and first iteration is proposed. The proposed work discuss about the design flow, parameters associated with it and simulation results of a compact Minkowski fractal microstrip band pass filter for different dielectric constant and thickness. Minkowski fractal Structured filter with substrate thickness of 0.8mm is operating at 5.1GHz with bandwidth of 1.6 GHz for 9.9 dielectric. And the same filter has a bandwidth of 2.4 GHz for 4.4 dielectric. A dual bandwidth is also achieved in the proposed filter with each of 0.8GHz bandwidth that can be used for different applications. A single filter can be used for more than one application. Minkowski Fractal Microstrip Filter is compact with good bandwidth and dedicated to C and X band applications. Keywords: Simulations, Filter, X and C band, geometrical structures, applications I. Introduction Most of the Microstrip filters are more popular and have more scope because of its miniature size, cost effectiveness, less weight and easy to fabricate. Hence these filters have found many applications in RF transceivers and wireless communications. Microstrip filters have less insertion loss, small size, wide band with high selectivity, these parameters are very much required and important in design of modern wireless communication systems [1, 2]. Microwave circuit designers will always meet the most challenging targets like, to produce miniaturized components with multiband operations. To achive these expectations, many fractal structures of different geometries are emerging and are becoming more attractive. Advantages of using these different geometries are compact size, part less electronic parts, and improved performance [3].The applications of different geometries of fractals are to produce miniature -sized filters and the use of fractals have many advantages [2, 3, 4]. Apart from, researchers had successively proposed many types of fractals to reshape the original microstrip lines and to obtain small size of bandpass filters for wireless communication applications.
