Design of modified folded dipole antenna for UHF RFID tag

Design of a Wideband Inductively Coupled Loop Feed Patch Antenna for UHF RFID Tag

"Although numerous works have been done in designing tag antenna, there are still many open issues that require further studies and research in order to truly exploit its potential. One of the issues is performance degradation of commonly used label typed dipole tag antenna [4][5][6] when placed on metal surface due to cancellation of tangential electric current at the boundary between the antenna and the metal surface [7], [8]. One of the many attempts to mitigate the problem is to separate the antenna and the metal surface by using a foam spacer to...

NFC Near Field Communications

RFID antennas form a particularly important element of any overall RFID system. There are two main types, namely the RFID tag antenna and the RFID reader antenna (this RFID antenna may also be part of an RFID transceiver or RFID printer, etc).

When designing an RFID antenna system, items that are determined by the system need to be considered. For example the...

1. Introduction

Inductive coupled RFID systems are being used in a huge number of applications such as payment (credit cards), ticketing (public transport and events), access control (company card) and identity verification (ePass, eID). Inductive coupled RFID systems operated in the 13.56 MHz band and are primarily covered by the ISO/IEC standards 14443, 15693, 18000-3 and 18092. The...

13.56MHz RFID Systems and Antennas Design Guide

13.56MHz RFID Systems and Antennas Design Guide:

1 Abstract:

This is aimed at providing 13.56 MHz RFID systems designers with a practical cookbook on how to optimize RFID systems and antennas. A thorough analysis of the most important RFID system parameters is presented. The emphasis is placed on physical concepts, rather than on lengthy theoretical calculations.
