The 3dBi UHF RFID PCB Antenna is a compact antenna designed for UHF RFID systems operating in the 902–928 MHz frequency range. With 3 dBi gain, circular polarization, and a wide beamwidth, it provides flexible RF coverage for a variety of RFID identification and tracking applications.
Its thin 100 × 90 × 1 mm design makes the antenna suitable for applications where installation space is limited. The antenna supports RFID logistics tracking, warehouse management, access control systems, and production line management.
Product Applications：
RFID Logistics Tracking
The antenna can support RFID identification and tracking of packages, goods, and tagged assets during logistics operations. It can be installed at designated RFID reading points to help improve item visibility.
Warehouse Management
In warehouse environments, the antenna can be used for RFID inventory tracking, item identification, stock movement monitoring, and receiving or dispatch operations.
Access Control Systems
The antenna can be integrated into RFID access control systems to support tag identification at designated access points and help manage the movement of tagged items or personnel.
Production Line Management
In manufacturing environments, the antenna can support RFID-based tracking of raw materials, work-in-process items, and finished products throughout different production stages.
