The increasing demand for radiofrequency and microwave devices in the challenging fields of communication
engineering has paved way for integrating the devices and making it as tiny as possible. This demands the need for
microstrip devices which occupy less space and are of much reduced size as compared to the devices made of lumped
components. This paper describes the design and analysis of a micro strip Butterworth low-pass filter using insertion loss
technique in X-band range that has a cut-off frequency at 10GHz with a sharp rejection of more than 100dB. This cut-off
range makes it a very useful device in Radar applications. The design of this low-pass filter was simulated by using the
schematic and Electromagnetic Simulation in Agilent’s Advanced Design System (ADS) software tool
