New design antenna for RFID UHF tags

A novel printed antenna is proposed for radio frequency identification. The antenna has a much wider bandwidth than known printed antenna, mostly planar antennas. The antenna geometry is much smaller than a printed dipole antenna at the same frequency band. The method of design and realization with experimental results is shown. The introduction includes basic concepts of RFID systems. The second part addresses the main characteristics of the proposed RFID tag antenna. The third part introduces a comparison between measurements and simulations. Few advantages of the proposed RFID tag that meets the objectives of low-cost and size reduction are presented in part four.
