Zusammenfassung:A single turn loop electronic article surveillance (EAS) gate. The gate includes a closed magnetic core, a multi-turn primary winding wound around the core, and a secondary loop passing through the core once. The secondary loop is a self-supporting single turn loop, and the secondary loop is a transmit loop that generates a magnetic drive field for the article detection gate system.
