Far Field directivity

The Identix 85DL4090 is a "Far Field” type UHF RFID antenna specifically designed for security applications (anti-theft) and loss prevention in retail - EAS Electronic Article Surveillance.

 

The 85DL4090 antennas has a unique radiation lobe, ideal for applications where a confined reading zone is required such as storefronts and corridors.
 
The radiating lobe has an opening angle of 40 ° horizontally and 90 ° vertically, and an electric tilt of 15 ° in the horizontal direction.

Identix 85DL4090 implements a high-gain, dual-linear orthogonal polarization radiating element which ensures maximum reading efficiency regardless of tags orientation.

It has a compact, modern and lightweight design that allows easy of installation and aesthetic integration into different types of environments.

 

Applications

  • RFID portals for loss prevention - LP and EAS

  • General use UHF RFID portals

  • Personnel and Vehicle access control
