In this paper, the design of a bandpass filter is discussed. There has been a rising trend in recent years towards the design and development of new microwave circuits based on metamaterials to best meet the advanced requirements of modern wireless communication systems. The implementation and use of metamaterial resonators is among the most widely used technical solutions to improve the electrical performance, and reduce the size of microwave devices and circuits such as antennas, couplers and filters. The proposed filter is based on the use of split-ring coupled square resonators; the realized circuit has been optimized in simulation using the electromagnetic solver HFSS. This filter is suitable for X-band applications with a bandwidth of 1200 MHz [10.5 GHz-13.4 GHz] with a total area of 24.54 x 4.84 mm2. The final circuit is mounted on a low cost FR4 substrate with a dielectric permittivity of 4.4 and a thickness of 1.6 mm. The originality of this filter is its selectivity in terms of bandwidth, having a wide band rejection and its easy integration with passive and active devices. Due to its straightforward construction, the suggested filter shows promising characteristics, for usage in wireless technologies for communications to offer an excellent performance.
