near field rfid reader With a low profile and a small form factor, a near-field antenna is perfect for short read range applications. Unlike far-field antennas which send out a propagating electromagnetic field, near-field antennas generate a local magnetic field. 7. Some GSM operators are using "NFC SIM" term to refer to a SIM card with .

Near-field UHF RFID reading: this expert guide explains how to avoid dead spots and optimize near-field UHF RFID tag reading.
With a low profile and a small form factor, a near-field antenna is perfect for short read range applications. Unlike far-field antennas which send out a propagating electromagnetic field, near-field antennas generate a local magnetic field.Near-field UHF RFID reading: this expert guide explains how to avoid dead spots and optimize near-field UHF RFID tag reading.In a passive RFID system, the reader transmits a modulated RF signal to the tag consisting of an antenna and an integrated circuit chip. The chip receives power from the antenna and responds by varying its input impedance and thus modulating the backscattered signal.

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.
NXP offers a complete portfolio of reader ICs supporting all contact and contactless smart cards, tags and NFC -near field communication devices. Near-field RFID reader antenna requires strong magnetic field, wide band and low gain characteristics, while the resulting magnetic field should be evenly distributed to avoid leakage read phenomenon. 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. 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 .
In this paper, a novel configurable loop array antenna based on resonator-loaded microstrip lines (RLML) is proposed to enlarge the interrogation zone of the reader antenna for near-field ultrahigh-frequency (UHF) radio frequency identification (RFID) system.
