Abstract

This report explains the design of Bandpass filter with Open Loop Dumbbell Shaped Defected Ground Structure (DGS). The developed of Bandpass filter started with constructed the circuit by using lumped element such as capacitors and inductors. This project has three main phases which are designing phase, fabricating phase and measuring phase. The Bandpass filter with Open Loop Dumbbell Shaped DGS is required to operate at 6GHz with 700 MHz of 3dB bandwidth for satellite broadcast and microwave relay application. The Bandpass filter is designed by using FR-4 printed circuit board. A comparison, the design of Open Loop Dumbbell Shaped DGS were analyzed to identify the better performance of the Bandpass filter. In this report there will be an overview on how to design, fabricate and measure the required filter that meet the given specification. The Advanced Design System (ADS) software 2011 which will be used in developing the filter will be overview. Lastly, the results of simulated and measured filter is analyzed and discussed. In the meantime, the future work and improvements to the performance of Bandpass filter will be further discussed.
