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...

RFID frequency ranges

1. The RFID frequency spectrum

RFID is considered as a non specific short range device. It can use frequency bands without a license. Nevertheless, RFID has to be compliant with local regulations (ETSI, FCC etc.)

oLF : 125 kHz - 134,2 kHz : low frequencies,

oHF : 13.56 MHz : high frequencies,

oUHF : 860 MHz - 960 MHz : ultra high frequencies,

oSHF : 2.45 GHz : super high...

Antenna Design for UHF RFID Tags-Review and a Practical ...

an overview of antenna design for passive radio frequency identification (RFID) tags is presented. We discuss various requirements of such designs, outline a generic design process including range measurement techniques and concentrate on one practical application: RFID tag for box tracking in warehouses. A loaded meander antenna design for this application is described and its various practical...

Many concerns have been expressed over the security and  privacy of RFID systems. Traditional applications, like largeasset tracking, were typically closed systems where tags did not contain sensitive information. However, as more consumer applications are developed, security, and especially  privacy, will become important issues. Much work has...

Abstract--Temperature monitoring is important in a num-

ber of fields, particularly cold supply chain applications. Most

commercial wireless temperature sensors consist of transceivers,

memory and batteries to maintain a temperature time history but

this is expensive and allows for limited sensor deployment. In this

paper, we propose a low cost...

Phased array - Wikipedia

Types[ edit ]

A passive phased array or passive electronically scanned array (PESA) is a phased array in which the antenna elements are connected to a single transmitter and/or receiver , as shown in the animation at top. PESAs are the most common type of phased array.

An active phased array or active electronically scanned array (AESA) is a phased array in which each antenna element has its own...
