- High gain performance
- Ultra-thin form factor
- Ideal for ceiling-mounted deployments
- Compact RFID UHF 3×3 patch antenna
- Pencil beam radiation pattern (40°/40°)
Product Overview
The UHF RFID patch antenna is engineered for high-precision and focused tag detection, featuring a pencil beam radiation pattern (40°/40°) that enables accurate reading within a defined zone. With circular polarization (LHCP), it ensures reliable performance regardless of tag orientation, making it ideal for applications such as retail tracking, inventory control, and access monitoring. Its high gain performance (up to ~10.8 dBiC) enhances read accuracy and system efficiency, even in demanding environments.
Designed with an ultra-thin form factor, this antenna allows for discreet and seamless ceiling-mounted installations in space-constrained areas. It supports global UHF frequency bands (ETSI & FCC), ensuring flexible deployment across regions. With low VSWR, strong front-to-back ratio, and minimal interference, it delivers consistent and reliable performance in multi-zone environments, making it a strong choice for modern RFID solutions.
