Abstract

This paper presents a novel folded microstrip patch antenna for passive RFID of objects containing metallic foils. The designed antenna can be integrated on or inside the package, and in the case of cigarette cartons approximately 1.0 m read range is achieved when the cigarettes are completely wrapped with aluminium foil. If the foils are removed or an empty carton is studied, read range almost doubles. When two tagged cartons are placed side by side, the read ranges drop due to coupling effects between the tags. The designed antenna has been proven to function well integrated to a package containing conductive foil and its performance is excellent also if the conductive material is not present
