Triple-band Printed Dipole Tag Antenna for RFID Application

In this paper, a triple-band printed dipole tag antenna is proposed for RFID application. The tri-band printed dipole antenna is designed at 0.92 GHz, 2.45 GHz and 5.8 GHz using Computer Simulation Technology (CST). In order to achieve triple-band operation, the proposed antenna contains two branch elements, which acts as an additional resonator. The designed antenna was fabricated using Taconic RF-35 substrate with a dielectric constant of 3.5 and thickness of 0.508 mm. The antenna’s parameters for triple-band operation are investigated and discussed. Then, this fabricated antenna is integrated with the UHF (902-928 MHz) to become a passive UHF tag. This tag is tested by measuring the reading distance and it is found that the proposed tag can be used for RFID application.
