Split-ring resonator is a popular research topic in literature. As known, it may be used in thedesign of electromagnetic metamaterials. Additionally, these structures can be preferred inmicrowave filter devices. In this study, a band-stop filter was designed for GSM-900 and 2.4GHz ISM band by using split-ring resonators. Two split-ring arrays (sizes of one of these arrayswere larger than the other) were loaded on the transmission line and each array consisted of fouridentical rings. Thus, a dual-band pass filter was obtained and this filter covered the frequency of0.91 (GSM) and 2.43 (ISM) GHz. Then, this proposed design was fabricated and measured.According to the measurement results, the fabricated structure operated at 0.93 GHz and 2.47.The experimental results were consistent with the simulation results. As a result, thanks to theproposed structure, two frequencies can be stopped at the same time. There is no need to design adifferent filter structure for each frequency.
