    Abstract

    A novel ultra-high-frequency (UHF) RFID reader antenna is proposed. The antenna has a unique property as being able to change its axial ratio (AR) without affecting its gain, beamwidth or impedance matching performance, enabling the isolated study of the effect of different axial ratios in RFID tag reading.This work was supported by EPSRC EP /S-19405/1 Channel Optimised Distributed Passive Sensor Networks
