DESIGN OF STEPPED IMPEDANCE LOW PASS FILTER AT 2.4GHz

In this era, life can't be envisioned without wireless communication. The microwave filter is a component which gives frequency selectivity in mobile, radar, satellite communication systems working at microwave frequency. Microwave low pass filter attenuates the unwanted signal above cut off frequency. For stepped impedance filter design high and low impedance lines are used. This paper describe s designing of Chebyshev approximated stepped impedance low pass filter at 2.4 GHz with the permittivity of value 4.2 and the height/thickness of the substrate is 1.6mm for the order n=3. Designed filter is simulated using Computer Simulation Technology.
