Abstract

The gain from Multiple-Input Multiple-Output (MIMO) techniques in wireless sensor networks equipped with miniaturized sensor nodes cannot be fully exploited due to the difficulty encountered when placing traditional multiple antennas with sub-wavelength physical separation. This paper presents a novel antenna array design using µ-negative metamaterial (MNG) structures that lead to low correlation between antennas when placed closely on a user’s body utilizing a telemedicine or a Body Area Network based system. The obtained correlation coefficient of 0.04 is low enough for realizing full diversity gain from using such antenna array on sensor nodes in a telemedicine WLAN environment. Furthermore, Bit Error Rate (BER) simulation result for a 2×2 Alamouti diversity scheme in an IEEE 802.11a system is also presented. Design and simulations are conducted using CST Microwave Studio which is based on the Finite Integration Technique. Results suggest that the proposed design would be a suitable candidate for telemedicine and BAN applications that are constrained by limited space.
