The 6dBi PCB antenna is a compact UHF RFID antenna designed for reliable tag reading and identification in logistics, warehouse, access control, and production line environments. Operating across the 902–928 MHz frequency range, it features circular polarization and a 6dBi gain to provide consistent RFID communication coverage.
With a compact 210 × 170 × 1.5 mm design, the antenna can be integrated into a variety of RFID equipment and installation environments. Its 50Ω impedance and SMA connector make it suitable for standard UHF RFID reader systems.
Product Applications：
The antenna can be used in a range of UHF RFID applications where stable tag identification and directional coverage are required.
RFID Logistics Tracking
In logistics operations, the antenna can support RFID tag identification for packages, pallets, containers, and other items. It can help improve visibility during receiving, sorting, transfer, and shipment processes.
Warehouse Management
The 6dBi antenna can be integrated into warehouse RFID systems for inventory identification and item tracking. Its directional coverage can help create defined reading areas around storage or handling points.
Access Control Systems
The antenna can be used in RFID-based access control applications to identify authorized tags and support automated entry management.
Production Line Management
On manufacturing lines, the antenna can help identify tagged products, components, work-in-process items, and containers at designated production stations.

6dBi Gain for Reliable RFID Coverage
With a 6dBi gain, the antenna provides practical RF coverage for UHF RFID applications in logistics, warehouse, access control, and production environments.
902–928MHz UHF RFID Operation
The antenna operates across the 902–928MHz frequency range, making it suitable for UHF RFID systems using this frequency band.
Circular Polarization for Flexible Tag Orientation
Circular polarization helps maintain RFID communication when tags are not consistently aligned with the antenna, making it useful for item tracking and identification applications.
Wide Beam Coverage
The antenna provides a 100° horizontal beamwidth and 75° vertical beamwidth, creating a practical reading area for designated RFID checkpoints and work zones.
Compact PCB Design
Measuring only 210 × 170 × 1.5mm, the slim PCB construction makes the antenna suitable for integration into RFID equipment and installations where space is limited.
SMA Connector and 50Ω Impedance
The SMA female connector and 50Ω impedance allow the antenna to be connected to compatible UHF RFID readers and RF equipment.
