In radio frequency identification (RFID), differences in spectrum policies and tag misreading
in different countries are the two main issues that limit its application. To solve these …

The near-field ultrahigh-frequency (UHF) quadruple-loop antenna (QLA) with uniform field
distribution for item-level tagging is proposed. The proposed antenna consists of quadruple …

This work proposes an improved electrically large antenna based on segmented loops for
near-field radio frequency identification readers. The paper applies dispersion analysis of an …

Two novel multisegment loops coupled ultrahigh-frequency (UHF) radio frequency
identification near-field (NF) antenna with a uniform and strong magnetic field distribution …

Radio-frequency identification (RFID) antennas are critical components in wireless
communication networks for the Internet of things (IoT). The RFID systems make it possible …

The near-field loop antenna with magnetic field enhancement using artificial transmission
line (ATL) is proposed in this work. At first, the working principle is revealed with the unit cell …
