ATU1031S
902-928 MHz | Compact Circular-Polarized Antenna
Compact UHF antenna for handheld readers and small RFID terminals
High-Gain UHF Reading
Designed for the 902-928 MHz UHF band with more than 1.5 dBic gain for stable tag coupling.
Low VSWR Design
VSWR <= 1.3:1 helps reduce reflected power and improves RF transmission efficiency.
Circular Polarization
Circularly polarized antenna design improves tag orientation tolerance in compact reading scenarios.
