Fabrication and test band a pass filter for the S-band ( 2.7 - 3.1 GHZ) radar

Abstract

The thesis discusses analysis, design, simulation and fabrication of a band-pass filter by using microstrip line technology. Filters are used as frequency selective devices in many RF and microwave applications. There is several application of a filter. For example it is used at the output of the oscillator to take out the required frequency or at the input of the receiver and the amplifier to pass the required frequency. The Advanced Design System Software is used for designing and simulation of band-pass filter. The filter is designed at a center frequency of 2.9 GHz with bandwidth of 400 MHz and using FR4 as a substrate. The final product will be integrated with the other RF front ends to create a receiver front end for Radar applications.
