Nexmosphere XR-A50 UHF RFID Antenna - 3 dBi Circular Polarization, SMA Female, 865-928 MHz

UHF RFID antenna delivering reliable tag detection up to 30 cm with circular polarization for orientation-insensitive reading. The XR-A50 is a planar antenna tuned for the global 865-928 MHz band, offering a 3 dBi gain and an SMA female connector for seamless integration with Nexmosphere X-Series controllers. Its low-profile ABS housing and integrated mounting points allow flush installation in retail displays, interactive kiosks, and smart shelves.

Advantages

Circular polarization minimizes missed reads when tags are rotated or misaligned, ensuring consistent performance in dynamic environments. The 50 Ohm impedance and VSWR below 1.5:1 maintain signal integrity, while the passive design draws power directly from the connected reader, eliminating extra cabling. The antenna's compact form factor and indoor-rated construction make it ideal for space-constrained applications.

Suitable for

• Interactive retail displays and product recognition
• Inventory management and smart shelf systems
• Access control and asset tracking in indoor spaces
• Integration with Nexmosphere XN-100 or XN-1000 controllers
