摘要： A core antenna system for use in electronic article surveillance (EAS) and radio frequency identification (RFID) systems. The core antenna system may include a core antenna. The core antenna may include a core, a first resonant winding disposed around at least a portion of the core, the first resonant winding having a first number of winding turns N1, and a second non-resonant winding disposed around at least a portion of the core, the second non-resonant winding having a second number of winding turns N2, the second number of turns greater than or equal to the first number of turns. The core antenna may be mounted on a shield plate and tuned to an operating frequency on the shield plate such that when the shielded core antenna is further mounted on a mounting surface, e.g., of a checkstand, no significant de-tuning of the antenna takes place.

摘要： An electronic article surveillance antenna system with wide interrogation zones has a number of core transceiver antennas with each connectable to a transmitter. The core transceiver antennas are adapted to be installed adjacent a ceiling of the wide interrogation zone and generate an interrogation signal into the wide interrogation zone. The core transceiver antennas each are connectable to a receiver to receive and detect a response signal from an electronic surveillance marker disposed in the wide interrogation zone. The system also has transceiver antenna coils with each connectable to the transmitter and adapted to be installed adjacent a floor of the wide interrogation zone. The transceiver antenna coils generate the interrogation signal into the wide interrogation zone and each is also connectable to the receiver to receive and detect the response signal from the electronic surveillance marker disposed in the wide interrogation zone.

摘要： A security tag includes an EAS component having a defined surface area, and an RFID component having a defined surface area. The EAS component surface area is configured to at least partially overlap the RFID component surface area. The RFID component includes an antenna which at least partially overlaps the first surface. A substantially planar spacer having a thickness is at least partially disposed between the defined surface areas of the EAS and RFID components. The thickness of the spacer is configured to effect a read range between an RFID reader and the RFID component. The RFID reader is capable of activating the RFID component when the RFID component is within the read range. The antenna has a complex impedance, and the EAS component forms a part of an impedance matching network of the antenna.

摘要： A near field meanderline like antenna assembly is disclosed which is configured to read an RFID label. The antenna is configured as a single and continuous conductor and is configured to extend from one end of a substrate forming a feed point to another end of a substrate forming a termination point. The termination point is connected to a ground through a resistor and the conductor is configured to direct current in two dimensions along the conductor. A localized E field directs a current distribution along an effective length of the antenna corresponding to a half-wave to a full-wave structure.
