Wearable textile systems are nowadays a fast growing field. Besides lower prices, wearable tags antenna have to resist laundry cycles which means high pressure, high temperature and humidity. This paper introduces a novel RFID textile tag antenna, made of two distinct antennas coupled together to protect UHF RFID system from environment stress : a circular(More)
This paper presents the design and prototyping of a low profile circularly polarized antenna for UHF RFID readers. This antenna has a very low profile, a low cost structure and is composed of two dipoles with 90° phase shift. In addition, to reduce the back beam radiation an artificial magnetic conductor surface (AMC) witch introduce a 0° of(More)
This paper presents the design and fabrication of a flexible tag for UHF RFID application in harsh environments. The proposed flexible tag has good performances when it is attached to non-metallic objects. Besides, after dipping in the water and in the chemical agents many times, the tag performances remain unmodified. Moreover, thanks to the protective(More)
This paper presents the design of a UHF RFID reader antenna for metallic environments. The design is based on the constructive wave phenomenon and on the use of a dipole antenna which provides a linear polarization parallel to its ground plane. In addition, the proposed antenna can be placed on metallic surfaces without impedance mismatch. The overall(More)
