Filters play an important role in microwave applications.Microwave systems have an enormous impact on modern society. Applications are diverse, from entertainment via satellite television, to civil and military radar system. In particular, the recent trend of multi-frequency bands and multifunction operations in wireless communication systems along with the explosion in wireless portable devices are imposing more stringent requirements such as size reduction tunability or reconfigurability enhancement and multiband operations for microwave circuits. This paper describes about the design of stepped-impedance microwave low pass filter by using Microstrip layout which works at 3.7 GHz for permittivity 4.4 value with a substrate thickness 1.6 mm for order n=3. The stepped-impedance low pass filter have a pass band ripple 0.1 dB. The development of the Microstrip filters are simulated by using IE3D simulator software.
