12dBi RFID Antenna for Long Range UHF Reading
High-Gain UHF RFID Panel Antenna for Focused Reading Zones
This 12dBi RFID antenna is designed for fixed UHF RFID systems where RF coverage needs to be directed toward a defined reading area.
Operating at 902–928 MHz, the antenna combines 12dBi gain, circular polarization and a 40° × 40° beamwidth.
The narrower beam helps concentrate RF energy toward the intended reading zone rather than spreading coverage across a wider area.
The antenna can be connected to compatible fixed RFID readers with external antenna ports, including 4-port and 8-port UHF RFID readers used for warehouse checkpoints, gates, vehicle lanes and other fixed installations.
Focused 40° × 40° RFID Coverage
The combination of 12dBi gain and a 40° horizontal × 40° vertical beamwidth makes this antenna suitable for applications where a more directional RFID reading zone is required.
Circular polarization provides more tolerance when tag orientation varies, while the specified front-to-back ratio of ≥25 dB helps concentrate radiation toward the front of the antenna.
This makes the antenna useful for controlled RFID zones such as vehicle lanes, warehouse checkpoints and dock-door installations where unwanted coverage behind the antenna should be reduced.
Actual RFID read range depends on the complete system, including reader RF output, cable loss, tag sensitivity, tag orientation, antenna position and the surrounding environment.

Compatible RFID Reader Setup
This external RFID antenna is designed for fixed readers that support external UHF antenna connections.
It can be used with:
- 4-Port UHF RFID Reader
Suitable for systems using several antennas around gates, production points, vehicle lanes or warehouse checkpoints. - 8-Port RFID Reader for Inventory Management
Suitable for larger installations where multiple RFID antennas are distributed across receiving, storage, conveyor or shipping areas. - The antenna uses an N-female connector, so the appropriate RF cable and connector combination should be selected according to the reader interface and installation distance.
- When several RFID antennas are used with one reader, antenna placement and cable routing should be planned around the required reading zones rather than simply maximizing distance.
Typical Antenna Installations
- Vehicle & Parking Lanes
The focused beam can be directed toward a vehicle identification area while the antenna is mounted separately from the RFID reader. - Warehouse Checkpoints
Suitable for fixed reading points where tagged pallets, cartons or assets move through a defined RFID zone. - Dock Doors & Logistics Entrances
The narrower beam pattern can help concentrate coverage around loading, receiving or shipping points. - RFID Gates & Access Points
Can be positioned around entrances where UHF tags need to be detected within a controlled directional reading area.

Frequently Asked Question
The top questions about RFID antenna
An RFID antenna transmits and receives RF energy between an RFID reader and compatible tags. In a UHF RFID system, antenna gain, polarization and beamwidth help determine the shape and direction of the reading zone.
A 12dBi antenna provides higher directional gain than lower-gain antennas. Combined with this model’s 40° × 40° beamwidth, it is useful where RF coverage needs to be concentrated toward a specific area.
It is designed for long-range UHF RFID system applications through its 12dBi gain and focused beam pattern. However, the antenna alone does not determine reading distance. Reader power, RF cable loss, tag performance and installation conditions also affect the final range.
It describes the approximate horizontal and vertical width of the antenna’s main RF beam. A narrower beam concentrates RF coverage into a more defined direction than a wider-beam antenna.
Yes, provided the reader operates within the supported frequency range and the correct RF cable and connector configuration is used.
The antenna uses an N-female connector with a 50 Ω impedance.
The antenna has an IP64 protection rating, an operating temperature range of -20°C to +60°C, and a specified maximum wind resistance of 50 m/s. Final installation should still account for mounting position, cable sealing and local environmental conditions
