Key Highlights
- Ultra-low profile ground mounting
- Circular polarization
- Designed for asset & people tracking
- High ~9.5 dBiC gain
- Rugged in-floor ability
Product Overview
The A5531C UHF RFID antenna is designed for high-performance ground-level tracking applications, delivering reliable and consistent tag reads in dynamic environments. With right-hand circular polarization (RHCP), it ensures accurate detection of tags regardless of their orientation, making it ideal for access control, conveyor systems, and people tracking. Its high gain of ~9.5 dBiC enables strong read performance even when items or individuals are moving quickly across the read zone.
Built with a rugged, fire-retardant ABS housing and an IP53 rating, the A5531C is suitable for demanding industrial environments. The ultra-slim profile allows seamless ground or floor-level installation without disrupting operations, while the standard SMA connector ensures easy integration with existing RFID systems. This combination of durability, performance, and installation flexibility makes it an excellent choice for modern RFID deployments.
