Keonn Advantenna-CP11 RFID-UHF-antenne met beperkt leesbereik, ETSI-frequentieband

Unlike conventional far-field RFID antennas that radiate broadly and create unintended reads, the KEONN Advantenna-CP11 focuses UHF energy into a tight, confined reading area. This circularly polarized antenna operates in the ETSI band (865–868 MHz) and delivers 8.5 dBiC gain with a 70° beamwidth, making it ideal for point-of-sale stations, kiosks, conveyor belts, and industrial workstations where precision and zone control are critical.

Highlights

• Confined reading area reduces stray reads and improves tag accuracy
• Circular polarization ensures reliable reads regardless of tag orientation
• High gain of 8.5 dBiC for extended read range within the defined zone
• Robust ABS housing with IP54 rating for indoor industrial environments
• RP-TNC female connector for secure, low-loss RF connections
• Wide operating temperature range from -20°C to +70°C

In daily use

The Advantenna-CP11 excels in applications where you must read only the items placed directly in front of the antenna. At a retail checkout, it prevents tags from neighboring lanes from being captured. On a production line, it limits reads to the immediate product, avoiding cross-talk from nearby stations. The circular polarization compensates for tag orientation, so items do not need to be perfectly aligned. With a VSWR below 1.3:1 and 50-ohm impedance, the antenna integrates seamlessly with standard UHF RFID readers. The front-to-back ratio greater than 20 dB further isolates the reading zone, minimizing interference from behind the antenna.
