Abstract

This thesis report discusses analysis, design, simulation, fabrication and testing of a band pass filter by using microstrip technology. Bandpass filters are used as frequency selective devices in many RF and microwave applications. There is several application of a bandpass 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. In this report, the choice of parallel coupled line filter topology is discussed. MA TLAB and Advanced Design System Software is use for calculation while Microwave office software is use for simulation. The project will be use to find the maximum bandwidth that be can achieve by the filter and beside that it also use to compare the performances of a different bandwidth for example bandwidth at 10%, 20% and at maximum bandwidth. The filter is designed at a center frequency of 2.4GHz with 12% bandwidth and using FR4 as a substrate. This filter can be good candidate for applications in the microwave communication.
