Impinj Guardwall Antenna
Impinj Guardwall Indoor Antenna is designed for item-level scanning and features a tightly controlled read zone and a powerful RF field, both of which are essential for penetrating deep inside densely packed cases. The Guardwall antenna absorbs energy from its opposing mate when employed in a pair, allowing very little to travel beyond the outside face. By limiting the read zone to the area between the two antennas, this arrangement maximizes stray read rejection. By boosting the intensity within the read zone, it also improves read reliability.
