Summary:
A novel inverted-Z tag antenna for circularly polarized operation in the UHF band RFID application is proposed. The structure of the proposed tag antenna comprises two inverted-Z strips, one printed on top side and the other on bottom side of the substrate, perpendicularly to each other. The measured 10-dB impedance bandwidth of the tag antenna is 33 MHz (897?930 MHz), and its 3-dB axial-ratio bandwidth is 32 MHz (899?931 MHz). The antenna gain and reading range of about 1.38 dBic and 14 m, respectively, were also demonstrated.
