Abstract
We present a circularly polarized antenna for wearable passive UHF RFID tag. The antenna consists of two layers without a physical connection. The upper layer is for achieving circular polarization by two orthogonal meandering dipoles connected to a split ring. The lower layer is a split ring resonator structure to achieve complex conjugate impedance matching with the RFID IC. The antenna has the maximum dimension of π × 222 × 3 mm3 and it provided a 3-dB axial-ratio bandwidth of 23 MHz (905-928 MHz) in the simulation. The estimated maximum attainable read range of the tag exceeds two metres.
