Abstract
Recent challenges, imposed on the wearable textiles antennas, have made the designers seeking for antenna structures that are multiband and with a compact size. In this paper, a compact dual-band printed dipole antenna has been presented as a candidate for use in wearable radio frequency identification RFID applications. The structure of the proposed dipole antenna takes the shape of the second order Wunderlich fractal topology. This fractal topology provides suitable and attractive shape; for security applications, the resulting antenna can be hidden in the cloth. The CST Microwave Studio is used to model, simulate, and evaluate the performance of the proposed antenna. The resulting antenna offers a compact size and dual narrow band resonant behaviour. The proposed antenna is designed to operate at center frequencies of 0.952 GHz and 2.66 GHz; covering dual bands of 0.973{1.013 GHz and 2.68{2.70 GHz respectively. These bands make the antenna suitable for dual-band RFID applications. Apart from the compact size and the dual-band response, results also show that the antenna presents acceptable radiation characteristics with reasonable peak gains throughout the two bands.
