Modified Sierpinski gasket fractal antenna with defected ground structure / Muhammad Izzuddin Fahmi Ab Aziz

This work presented the design, simulation and analysis of Fractal Antenna With Defected Ground Structure. The antenna was fabricated on ROGERS 5780 substrate of dielectric constant, er = 2.33 with thickness, h of 0.5 mm while the center frequency was 5.8 GHz and using insert feed line. Designing and simulation of the antenna were undertaken by using the commercial electromagnetic simulator, Computer Simulation Technology (CST) Microwave Studio. The Vector Network Analyzer (VNA) was used for measurement and analysis the parameters of the antenna. The value of the parameters of the antenna was compared between simulation and measurement. The performance of the antenna was improved with the introduction of slot defected ground structure. It was observed that both the measured and simulated values of all the parameters were close with each other and compact size. The performance of the antenna was improved by using defected ground structure at frequency 5.8 GHz.
