In this Paper, stepped impedance low pass filter is described. A high performance, low cost, small size, third order multilayered stepped impedance low pass filter is designed and it is fabricated in the middle layer. A periodic pattern of spiral hexagon split ring resonators are etched on the top layer of metamaterial structure. This paper describes the designing of stepped impedance low pass filter at cut off frequency 2.43GHz, with microstrip line implementation. Computer simulates technique (CST) software is used to simulate the filter, which is commonly used in microwave applications. The proposed filter has better results as compared to conventional stepped impedance low pass filter.
