Abstract

In this paper, a novel tag antenna is proposed; it has a very simple structure that does not require a ground plane or shorting pins. The proposed tag antenna has significant advantages over other types of tag antennas for metallic objects, such as low cost, light weight, and ease of fabrication. The body of the antenna is printed as a single planar strip line on a thin PET substrate (polyethylene, epsi_r=3.9, tandelta=0.003) and it is mounted on foam substrate (epsi_r=1.0). The detail design parameters of the proposed antenna were optimized using the Pareto genetic algorithm (GA) in conjunction with the IE3D EM simulator and the resulting tag antenna has readable ranges of about 2.8 m when mounted in the air and 1.8 m when mounted on a metallic surface
