Design of a miniaturized dipole RFID tag antenna

This study introduces a new design strategy for an RFID Tag.Methodology/Findings: A low-profile meander line dipole antenna has been fabricated as a proof of concept due to its electrically small size and simple structure. Good agreement is achieved between the results obtained by this method and those calculated by simulations using CST. The antenna is designed to operate at a frequency of 915 MHz, allocated for UHF RFID. In order to ensure that the design has good performance, all of the antenna parameters are optimized. The results of antenna parameters such as radiation pattern,bandwidth, gain and return loss are also considered. This made it possible to achieve a reduction in size of the order of 40%. Applications: Meander line dipole antennas are useful as radio frequency identification (RFID) tag antennas because of their relatively high radiation efficiency and small size.
