NFC stands for Near Field Communications, a short-range wireless technology operating at 13.56 MHz that enables communication between devices at a distance less than 10 cm and a transmission rate of up to 424 .
several approaches to implementing near field UHF RFID systems using existing reader . In this paper, an overview of near field UHF RFID is presented. This technology .several approaches to implementing near field UHF RFID systems using existing reader modules and tag ICs. 1. First, and most obvious, approach is to use an existing UHF RFID system with full reader output power and standard (far-field) reader antennas and tags. It can be expected that in most cases the UHF RFID tag which In this paper, an overview of near field UHF RFID is presented. This technology recently received attention because of its possible use for item-level tagging where LF/HF RFID has traditionally been used. We review the relevant literature, discuss basic theory of near and far field antenna coupling in application to RFID, and present some .
Near-field UHF RFID reading: this expert guide explains how to avoid dead spots and optimize near-field UHF RFID tag reading. The purpose of this paper is to apply fragment-type wires to design UHF RFID reader antenna to cover an electrically-large near-field zone at the 915 MHz RFID band.
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. In this paper, an overview of near field UHF RFID is presented. This technology recently received attention because of its possible use for item-level tagging where LF/HF RFID has. This paper presents a switchable near-field (NF) and far-field (FF) antenna designed for ultra-high frequency (UHF) radio frequency identification (RFID) applications. The antenna consists of a four-dipole array and a feeding network. Currently, ultra-high frequency (UHF) near-field RFID technology are fast developed in item-level identifications such as sensitive products tracking, biological products and medical products (blood, medicines, vaccines), biosensing applications and so on [8–12].
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 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).several approaches to implementing near field UHF RFID systems using existing reader modules and tag ICs. 1.
