Abstract: Micro strip filters plays various roles in wireless and mobile communication systems to meet the emerging telecommunication challenges with respect to size, performance and cost. In this filter with changing every high or low impedance characteristics such as length or width desired characteristics can be obtained. In this paper different order stepped impedance micro strip line filter have been designed using Hyper lynx 3D EM software at 5GHz. In present work, various even pole (2, 4, 6 and 8) and odd pole (3, 5, 7 and 9) are designed and compared in micro-strip configuration.
