Abstract

The paper presents the design and analysis of a corona-shaped fractal antenna with a defected ground structure (DGS) for wireless applications. The fractal concept with an inverse patch medium DGS (IPM-DGS) technique is proposed and applied to achieve multi-band frequencies with a high efficiency. The same structure on the top face of the antenna is used as the ground face in an inverse medium. Resulting in the same corona-fractal structure as the DGS. The overall dimension of the antenna is 55mm x 55mm (0.48λ × 0.48λ at the lowest resonant frequency) and is designed on a felt substrate to operate at 2.62 GHz, 3.02 GHz, 3.35 GHz, 3.5 GHz, and 3.62 GHz. The maximum gains of 4.06 dBi and 5.13 dBi with efficiencies of 82% and 80 % are observed at 2.62 GHz and 3.02 GHz, respectively, making the proposed antenna potentially suitable for wearable WBAN/WLAN applications.
