Abstract

This thesis provides the reader with a detailed and comprehensive study of theory, design, fabrication, result and problem encountered in the designing bandpass RF microwave filter. The approaches used to achieve this project are through literature survey, dimensional calculation and computer software simulation. These approaches are used to analyze the characteristics and the required specification before fabricating the microstrip bandpass filter, computer simulation is the best technique to get the solution because it is fast and economical. The bandpass filter has several types and design. There are parallel-coupled microstrip bandpass filters, edges microstrip bandpass filter and hairpin microstrip bandpass filter. The filter design is concentrated on the parallel-coupled bandpass microstrip filter operating at 5.8GHz by using FR4 as a substrate. To achieve this purpose, computer software, Microwave Office 2004 is used to analyze the characteristics of the microstrip bandpass filter and to determine its suitable parameters. The Emsight Simulator is developed by using a technique called "Method of Moment (MoM)". Meanwhile, insertion loss measurement is one of the critical measurements that have been used to analyze performance quality. With this method, it can find out whether the parallel-coupled microstrip bandpass filter can be design in good condition or not.
