A universal ultrahigh-frequency (UHF) near-field radio-frequency identification (RFID) reader antenna with wide bandwidth and adjustable reading area is proposed in this letter.A broadband segmented loop antenna is presented for ultra high frequency (UHF) near-field radio frequency identification (RFID) applications. Using a segmented line, the current distribution along the loop is kept in phase even though the perimeter of the loop is more than two operating wavelengths so that the proposed antenna generates strong . In the design of ultra-high-frequency (UHF) radio frequency identification (RFID) near-field antennas, realising an antenna with electrically large size, wide frequency band, and far read range has always been a challenge.Abstract—In this letter, a radio frequency identification (RFID) reader antenna designed for near-field and far-field operation at the European ultrahigh frequency (UHF) band is presented.
An ultra-high frequency (UHF) travelling wave antenna based on complementary split ring resonator (CSRR) element is investigated in this study for pure near-field radio frequency identification (RFID) system.This paper presents two near field reader antennas for applications in the UHF radio frequency identification (RFID) system. Strong vertical and horizontal magnetic fields in near zones are respectively excited by those two reader antennas, so that the readable distance of the nearfield tags attached on objects can be enhanced significantly.
This article designs two UHF capacitively coupling RFID near-field reader antennas with uniform vertical electric field distribution. Both antennas have broadband characteristics.A novel broadband antenna for ultrahigh-frequency (UHF) near-field radio frequency identification (RFID) applications is presented. The antenna is composed of a grounded coplanar waveguide (GCPW), a coplanar stripline (CPS), a lumped balun, multiple resistors, and a .
This paper proposed a novel antenna for ultra-high frequency (UHF) radio frequency identification (RFID) near-field applications with uniform distribution of the electric field along the x-axis (Ex), and the y-axis (Ey). The proposed antenna adopted a spiral structure to achieve broadband and multi-polarization.discuss basic theory of near and far field antenna coupling in application to RFID and present some experimental measurements with emphasis on physical tag performance.
