A near‐field UHF L‐shaped dipole antenna array with LC‐balun integration for item‐level tagging systems is proposed and investigated in this letter. The antenna consists of four dipole antennas and an impedance matching network with four LC‐baluns. Each dipole is fed by parallel stripline which connects to LC‐baluns for miniaturization. The proposed near‐field UHF dipole array can achieve not only the compact size (∼1/3λ0 at 920 MHz) but also the seamless sensing of 100% read accuracy within the operating distance (up to 10.5 cm).
