There is an increasing demand for microwave systems to meet emerging telecommunication challenges with regard to cost, size and performance. In this paper a new multilayered fifth order microstrip low pass filter is designed retaining all above factors. The new microstrip low pass filter with cut off frequency 3.4GHz based on metamaterial structure is proposed and simulated. The filter is fabricated in the middle layer and a periodic pattern of complimentary split ring resonators (CSRR) are etched on the top layer of metamaterial structure. Computer simulated technique (CST) is used to simulate the filter design. Main objective of this Paper is to offer a unique RF/microwave microstrip filter based on the complementary square ring resonator structures. A comparison between a traditional microstrip low pass filter with a new modified design of multilayered microstrip low pass filter based on complimentary split ring resonator structure has been done. The return loss and insertion loss has improved significantly both in pass band and stop band.
