Keywords:
Endfire radiation pattern, gain, QuasiYagi antenna, RFID readerAbstract
This paper describes a compact printed Quasi-Yagi antenna for ultra high frequency (UHF) radio frequency identification (RFID) reader that can be used in both Europe and US regions. The proposed antenna is a Yagi type structure with a microstrip-tocoplanar stripline transition, a meander dipole, a folded finite-size ground plane and a rectangle ground plane. The proposed antenna has compact size (0.18?×0.24?). The proposed antenna has an endfire radiation pattern within operation bandwidth, with peak gain values of more than 3 dBi and return loss is less than -10 dB in approximately 100 MHz band that can cover European and US RFID bands (860 MHz - 960 MHz). We described the antenna structure and presented the comparison of simulation results with experimental data. Good return loss and radiation pattern characteristic are obtained, measured results are presented to validate the usefulness of the proposed antenna structure for RFID reader.
