    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 device detaches a combination electronic article surveillance (EAS) and radio frequency identification (RFID) tag (EAS/RFID tag), and includes a detacher (magnet) to selectively disengage a clutch release disposed in a first portion of the combination EAS/RFID tag, a near field antenna configured to electronically read information stored in a second portion of the combination EAS/RFID tag. The antenna encircles the detacher and reads information from the second portion of the combination EAS/RFID tag at a position relative to the detacher when the second portion of the tag is disposed at any angle relative to the detacher and only when the detacher is positioned to disengage the clutch release. As long as the portion of the EAS/RFID tag containing the clutch end mechanism is located over the detaching magnet, the RFID label is in a valid detection zone regardless of its orientation relative to the antenna.

    摘要： A near field linear element microstrip antenna is disclosed which is configured to read an RFID label such that a localized electric E field emitted by the antenna at an operating wavelength resides substantially within a zone defined by the near field. The localized E field directs a current distribution along an effective length of the antenna corresponding to a half-wave to a full-wave structure.
