9dBi UHF RFID Antenna with Circular Polarization
UHF RFID Panel Antenna for 4-Port and 8-Port Readers
This 9dBi UHF RFID antenna is designed for fixed RFID systems that use external antennas, including compatible 4-port and 8-port UHF RFID readers.
It operates across 860–960 MHz and uses circular polarization to provide more tolerance when RFID tag orientation varies within the reading zone.
With 9dBi gain, 70° horizontal beamwidth and 60° vertical beamwidth, the antenna can be positioned to create a defined UHF RFID reading area for warehouse, gate, vehicle and access-control installations.
9dBi Circular Polarization for Defined RFID Coverage
The antenna uses circular polarization, which is useful where RFID tags may not always face the antenna in the same orientation.
Its 9dBi gain provides a directional RF pattern, while the 70° horizontal × 60° vertical beamwidth helps system designers plan antenna placement and reading-zone coverage.
Actual RFID reading distance is determined by the complete system, including reader output power, RF cable loss, tag sensitivity, tag orientation and the installation environment.

Compatible RFID Reader Setup
this external RFID antenna can be connected to compatible fixed UHF RFID readers with external antenna ports.
It is suitable for use with:
- 4-Port UHF RFID Reader
For systems requiring several antenna positions around doorways, gates, production points or smaller multi-zone installations. - 8-Port RFID Reader for Inventory Management
For warehouse or inventory systems requiring more antenna positions across receiving, storage, conveyor or shipping areas. - The final antenna quantity and placement depend on the required reading zones, RF cable length, reader configuration and site layout.
Typical Antenna Installations
- Warehouse & Logistics Checkpoints
The antenna can be mounted at receiving areas, shipping points or material-transfer locations where tagged cartons, pallets or assets pass through a defined reading zone. - RFID Gates & Doorways
The 70° × 60° beam pattern can be considered when positioning antennas around entry points, RFID gates or controlled passages. - Vehicle & Parking Lanes
The antenna can be installed separately from the RFID reader, allowing the antenna angle and mounting position to be adjusted according to the vehicle lane. - Access Control Points
Suitable for fixed UHF tag identification where the antenna needs to be positioned independently from the reader enclosure

Frequently Asked Question
The top questions about UHF RFID antenna
The antenna operates across 860–960 MHz, covering common UHF RFID frequency regions.
Yes, provided the reader frequency range, RF connector and system configuration are compatible with the antenna.
The antenna uses an N-female connector.
The specified beamwidth is 70° horizontal and 60° vertical.
The antenna has an IP67 protection rating, operates from -20°C to +60°C, and has a specified maximum wind resistance of 50 m/s.
Circular polarization provides more tolerance when tag orientation varies, which can be useful in applications where tags are not always aligned in the same direction.
The antenna itself does not determine a fixed reading distance. Actual RFID read range depends on the reader output power, RF cable loss, tag performance, antenna placement and installation environment.
