The proposed .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. This paper proposed a novel antenna, with uniform horizontal electric field distribution and multi-polarization, for UHF RFID near-field applications. The proposed antenna has a wide frequency band and low gain.
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.A rule of thumb is that near-field UHF RFID is sufficient up to a distance of about one wavelength, which in UHF frequencies equals about 30 cm or 12 inches. If the reading distance exceeds that, the tag is required to have an antenna structure that is .

This article designs two UHF capacitively coupling RFID near-field reader antennas with uniform vertical electric field distribution. Both antennas have broadband characteristics.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. 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 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.
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 . 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.

Add support for background tag reading to your app by turning on Associated Domains under the project’s Capabilities tab. This step adds the Associated Domains Entitlement to your project’s entitlement file and to the app ID. Next, .The tag reader is a simple to build/use NFC tag reader, specially created for Home Assistant. It is using a D1 mini ESP 8266 and the PN532 NFC module. The firmware is built using ESPhome.
