A Simple Uhf Rfid Circularly-Polarized Reader Antenna Design
In this paper, the simple antenna is proposed for ultra high- frequency (UHF) radio frequency identification (RFID) application. It is designed to achieve circular polarization with unidirectional beam. The antenna is composed of the truncated radiation patch and ground plane. The simulation results show that the antenna achieves the return loss of -31.92 dB, gain of 8 dBic, axial ratio (AR) of...

Robust RFID Tags Track Firearms - mwrf.com
This block diagram identifies the components of an RFID system.
The RFID tags are powered from the RF field generated by the external electronic devices (the interrogator/reader) generating the RF field and designed to communicate with (read) the tag. Tags designed to this standard are "vicinity devices" and have a limited read range of approximately 1 m depending on their size and the size and...

Trolley Scan - Can RFID tags replace barcodes cost ...
The RFID tag to replace barcodes is about to arrive from a number of different suppliers who are all working towards this goal. At the end of the day, all the tags offered will comprise of a small integrated circuit and an antenna in some form. With the departure from the 125KHz frequency range by manufacturers targeting this market, the need for expensive 1000 turn coils is gone drastically...
