WIDE EXIT ELECTRONIC ARTICLE SURVEILLANCE ANTENNA SYSTEM |
摘要 |
An electronic article surveillance antenna system for wide exit interrogation zones is provided. In a first aspect, a first and a second transmit antenna, each adapted for installation on opposite sides of a wide interrogation zone. A third transmit antenna is adapted for installation adjacent the ceiling of the wide interrogation zone. The first, second, and third transmit antennas are connectable to a transmitter for generation of an interrogation signal for transmission into the wide interrogation zone. A plurality of amorphous core receiver antennas are adapted for installation in the grout region of a floor of the wide interrogation zone. The output of each of the plurality of amorphous core receiver antennas are connectable to a receiver for detection of a response signal from an electronic article surveillance tag disposed in the wide interrogation zone. The response signal is responsive to the interrogation signal
