| Description: |
A near-field antenna for ultra-high frequency radio frequency identification (RFID) reader with a multi-ring structure and uniform magnetic field was designed. The antenna was circular in shape and consisted of 8 fan-shaped radiating patches distributed in rotation. Through coupling between fan-shaped radiating patches and loading parasitic arc-shaped patches, the surface current of the antenna showed the same rotation direction, which could generate a relatively uniform magnetic field and a multi-polarized electric field in the identification area. The antenna had a diameter of 130 mm and was printed on a flame retardant 4 (FR-4) dielectric substrate with a thickness of 1.6 mm. The measured results show that the bandwidth of the reflection coefficient | S 11 | |
