Flexible Folded-Patch Antenna With Serrated Edges for Metal-Mountable UHF RFID Tag

A folded-patch tag antenna (30 mm x 30 mm x 3 mm or 0.0912λ x 0.0912λ x 0.009λ) is designed for mounting on metallic objects. It consists of a serrated patch radiator, ground patch, and loopshaped stub, which are made on a flexible inlay wrapping around soft foam. Digital serration is used for fine-...

Beschreibung
Zusammenfassung:A folded-patch tag antenna (30 mm x 30 mm x 3 mm or 0.0912λ x 0.0912λ x 0.009λ) is designed for mounting on metallic objects. It consists of a serrated patch radiator, ground patch, and loopshaped stub, which are made on a flexible inlay wrapping around soft foam. Digital serration is used for fine-tuning the resonant frequency. The proposed tag antenna is able to achieve a read range beyond 7 m on metal. It can also be read from at least 3.5 m when used on dielectrics with permittivity in the range from 1 to 12.
