Abstract: In this paper a simple approach of designing the microstrip low pass and bandstop filter is presented. The microstrip stub based low pass filter with 2.4 GHz and attenuation of more than 60 dB at 4 GHz frequency is designed. The bandstop filter is also designed with notch characteristics at 2.4 GHz frequency. The fractional bandwidth of designed filter is estimated to be 30% with 117 dB of attenuation is recorded at notch frequency of 2.4 GHz in SIR based bandstop filter topology. The bandstop filter is implemented using coupled line structure as well as step impedance resonator techniques. The filters are designed on Roger RC40003C substrate. The design and analysis of filter with its layout and EM simulation is accomplished using Agilent ADS software. These filters can be used in front end transceiver systems, antennas, and modern wireless communication systems.
