Antenna 85DL4090
High-performance wide-beam RFID antenna
With two radiating elements
The Identix 85DL4090 is a far-field UHF RFID antenna specifically designed for transition zones, reading of difficult-to-detect items, and retail loss prevention applications, such as Electronic Article Surveillance (EAS) systems.
Its fan-shaped radiation pattern is ideal for creating controlled reading zones, making it suitable for locations such as store entrances, corridors, checkout areas, and loading docks.
The antenna features a radiation lobe with a 40° aperture in the horizontal plane and a 90° aperture in the vertical plane, along with a 15° horizontal inclination, optimizing coverage in specific areas and reducing unwanted readings outside the target zone.
Featuring linear polarization, high gain, and two radiating elements, the Identix 85DL4090 ensures reliable tag reading performance, even when tags are unfavorably oriented.
Its modern, compact, and lightweight design facilitates easy installation and allows for aesthetic and discreet integration into various environments, including retail, logistics, industry, and asset security.
