Guardwall Antenna

RFID HARDWARE – Antennas – MatchBox antenna

For item-level reading of packed goods, the Guardwall antenna provides a tightly controlled read zone and intense RF field, critical to penetrating deep into packed cases. When used as a pair, the Guardwall antenna absorbs energy from its opposing mate so that very little passes beyond the exterior face. This configuration maximizes stray read rejection by constraining the read zone to the area within the two antennas. It also increases read reliability by maximizing the intensity within the read zone.
