Abstract

Some dual-band RFID (radio frequency identification) tag antennas were obtained from symmetric dipole type configurations by exploiting the harmonic frequencies. Based on this situation, new antenna configurations, easy to adjust, were proposed by breaking the symmetry of the original dipole antenna. Following this approach, we found novels dual-band RFID antenna operating at UHF and Microwaves.
