In this paper near-field coupling in UHF-RFID systems is investigated. The wireless power transfer among reader and tag antennas is addressed through a numerical model involving different reader antennas and a short-range tag. System performance is investigated in terms of both mutual impedance and power transfer efficiency. Finally, a new near-field reader antenna based on coplanar waveguide technology will be described

Abstract

In this paper near-field coupling in UHF-RFID systems is investigated. The wireless power transfer among reader and tag antennas is addressed through a numerical model involving different reader antennas and a short-range tag. System performance is investigated in terms of both mutual impedance and power transfer efficiency. Finally, a new near-field reader antenna based on coplanar waveguide technology will be described
