This paper presents our investigation into a novel ultrahigh-frequency (UHF) radio frequency identification (RFID) multipolarized reader antenna based on a pair of symmetrical meandering open-ended microstrip lines for near-field applications.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 paper proposes a three-dimensional uniform ultra-high frequency (UHF) near-field radio frequency identification (RFID) reader antenna. The antenna achieves a uniform electric field in the x and y directions by placing a single branch microstrip line along the x -axis and y -axis directions, respectively.

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).In this paper, two UHF reader antennas based respectively on inductive and capacitive couplings for near-field RFID applications are presented. To identify item-level tags with inductive coupling, a loop-type antenna is developed to have strong magnetic fields in near zone. This article designs two UHF capacitively coupling RFID near-field reader antennas with uniform vertical electric field distribution. Both antennas have broadband characteristics. 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.
Abstract— An overview of the state-of-the-art of the antennas for ultra high frequency (UHF) near-field (NF) radio frequency identification (RFID) readers is presented. The specific requirements, design considerations, and design guidelines are addressed. A segmented loop antenna with capacitive couplers is proposed for ultra-high frequency (UHF) near-field radio frequency identification (RFID) applications, which is capable of generating a strong and uniform magnetic field in a near-field zone even though the perimeter of the loop is comparable to the operating wavelength.
