1 THE JOURNAL OF KOREAN INSTITUTE OF ELECTROMAGNETIC ENGINEERING AND SCIENCE Feb.; 29(2), ISSN (Print) ISSN X (Online) UHF-HF RFID UHF-HF Dual-Band RFID Tag Antenna Design for Boxes 남세현 강주원 정유정 Seahyeon Nam Juwon Kang Youchung Chung 요약 RFID(Radio Frequency Identification) 920 MHz UHF(Ultra High Frequency) MHz HF(High Frequency) NFC(Near Field Communication). HF NFC, UHF RFID. simulation, HF NFC NXP Ntag213 Loop. UHF Alien Higgs-3, HF HF,. Abstract This paper introduces the development of HF(NFC) and UHF band(13.56 MHz, 920 MHz) tag antennas, imbedded in a box. In dual band antennas, the HF band tag can be used to inspect the box using NFC, and the UHF band tag can be used for logistics. The dielectric constant of the box material is measured and used for simulation. The Ntag213 chip manufactured by NXP is used in HF loop antennas, since NFC is possible with Ntag213. For the UHF band, the Higgs-3 chip manufactured by Alien is used. The HF tag antenna is located at the center of the UHF tag antenna, and the location of the HF tag antenna is calculated while considering coupling effects. The designed tag can be used by both the bands for the purposes of logistics and authentication. Key words: Dual Band RFID Tag, UHF & HF Tag, Tag for Box, NFC and UHF Tag. 서론 RFID.,,,, /,,.
