A prototype modified Sierpinski gasket fractal antenna with ring-shape defected ground structure (DGS) at center frequency of 5.8 GHz was designed and simulated using Computer Simulation Technology (CST) software and fabricated. RT Duroid/RO5880 substrate with dielectric constant, r of 2.2 with thickness of 0.381 mm was used. The Vector Network Analyzer (VNA) was used to measure the parameters of the antenna such as return loss, VSWR and input impedance. A ring-shape defected ground structure was proposed to improve the overall performance of the antenna. The simulated and measured results were close with each other and achieved the required specification for this work at 5.80 GHz with the return loss of -25.307 dB and unidirectional radiation pattern was realized. There was a significance reduction in size of the prototype antenna and this suits well with the current requirements for mobile wireless devices.

The property of self-similarity, recursive irregularity, and space filling capability of fractal antennas makes it useful for various applications in wireless communication, including multiband miniaturized antenna designs. In this paper, an effort has been made to use the metamaterial structures in conjunction with the fractal patch antenna, which resonates at six different frequencies covering both C and X band. Two different types of square SRR are loaded on the fractal antenna for this purpose. Particle swarm optimization (PSO) is used for optimization of these metamaterial structures. The optimized metamaterial structures, after loading upon, show significant increase in performance parameters such as bandwidth, gain, and directivity.
