4dBi Ultra-Slim UHF RFID Antenna – 400x34x5mm

An 865–868 MHz antenna is designed for UHF RFID and low-power wireless applications operating in the European ETSI SRD band. Typical uses include UHF RFID readers (EPC Gen2 / ISO 18000-6C), asset tracking, warehouse management, access control, smart retail, race timing, and IoT/M2M systems deployed in Europe and other regions following ETSI regulations.
Airplux offers this band across multiple product families: the ETSI 865–868 MHz RFID antenna line (3–15 dBi PCB, panel and mat antennas), near-field RFID antennas, narrow-beam antennas, and ETSI UHF integrated reader antennas. For example, the 3 dBi circular-polarized PCB antenna APRIA8003CM-137 suits compact desktop readers, while high-gain panel models support long-range portal and gate applications.

ETSI 865–868 MHz antennas are tuned for the European UHF RFID band (ETSI EN 302 208), while FCC 902–928 MHz antennas cover the North American band (FCC Part 15). The two bands do not overlap, so an antenna optimized for one will have degraded VSWR, gain and read range on the other. Choose the version that matches your reader’s regional profile.
Airplux manufactures both variants with matching mechanical designs — e.g., the ETSI 865–868 MHz panel series and the FCC 902–928 MHz series are available at the same gain levels (3–15 dBi). For global or multi-region deployments that need one SKU for both markets, the wideband UHF 860–960 MHz antenna line covers both bands in a single antenna, ideal for asset tracking and smart retail projects shipped worldwide.

It is not recommended. A 915 MHz antenna is resonant around 902–928 MHz; at 865–868 MHz its impedance match detunes, VSWR rises, and radiated efficiency drops — typically reducing RFID read range by 20–40% or more, and in some regions pushing the system out of regulatory compliance. Always match the antenna to the device’s operating band.
If your hardware must serve both Europe (865–868 MHz) and North America (902–928 MHz), use a genuinely wideband model instead of compromising with a single-band antenna. Airplux’s UHF 860–960 MHz RFID antenna series maintains consistent gain and low VSWR across the entire 860–960 MHz range, so one antenna design can be certified and deployed in both regions.

A 175° horizontal beamwidth and 55° vertical beamwidth describe a radiation pattern that is much wider horizontally than vertically. The Airplux APRIA8004LX provides broad horizontal coverage with a more limited vertical spread. This pattern can be useful in installations where tagged items are distributed across a horizontal area but vertical coverage needs to remain more controlled. Actual reading performance depends on antenna placement, tag orientation, reader settings, and nearby materials.

A 400 mm ultra-slim antenna can be considered for cabinets and fixtures that have a narrow, elongated mounting area. The Airplux APRIA8004LX measures 400 × 34 × 5 mm and weighs approximately 0.2 kg, making it suitable for evaluating space-constrained installations. Before mounting, check the available dimensions, cable routing, tag positions, and nearby metal surfaces, as metal can affect RFID performance. Test the installed antenna with the actual tags and cabinet contents to verify coverage.

Choose based on the available mounting length and the size of the intended reading area. The Airplux APRIA8004LX measures 400 × 34 × 5 mm, while the APRIA8005LX-670 measures 670 × 34 × 5 mm. The shorter model may fit more easily into compact cabinets or equipment, whereas the longer model provides a longer antenna structure. Their gain and beamwidth specifications also differ, so compare the complete radiation patterns rather than selecting by length alone.
