Product Overview

The SP11 UHF RFID antenna is designed for short-range, high-accuracy tag detection in controlled and proximity-based environments. Featuring circular polarization, it ensures reliable reads regardless of tag orientation, while the wide beam radiation pattern (70°/70°) provides consistent coverage without precise alignment. This makes it ideal for applications such as embedded systems, asset tracking, and close-range identification.

Built with a compact and lightweight design, the SP11 allows for easy integration into surfaces and devices. With an IP67-rated enclosure, it is suitable for both indoor and outdoor use, offering protection against dust and water. Its stable performance, flexible mounting options, and durability make it a dependable solution for modern RFID deployments.
