Wireless communication is need of world. In this era life cannot imagine without it. In this paper, it has been designed a micro-strip low pass filter for L-band Application. Micro-strip Filter is designed from the methods of Step impedance low pass prototype filter, basic property of micro-strip filter like simulated design, return loss, amplitude frequency graph and smith chart discussed. Finally it is shown that -3dB return loss is shown at the frequency of 1.584GHz and this frequency come in the L-band so this filters showing a very sharp cutoff and used for different application of L-band (1-2GHz).
