Abstract

This paper represents design of 3GHz hairpin filter with Defected Ground Structure (DGS) for Microwave Imaging application by using Advanced Design System (ADS) software and FR4 substrate. Hairpin filter is one of the most popular microwave filters because of its compactness. Thus, to enhance its performance detected ground structure is implemented to the filter. The filter is designed to operate at 3GHz frequency with fractional bandwidth of 6.67%. This project is designed and simulated by using Advenced Design Structure (ADS) and all the calculation is done on LineCALC the ADS tools. This project uses FR4 board as the substrate and it is fabricated by undergo etching process. Improvement is should be done to enhance the filter performance.
