Abstract: An electronic article surveillance (EAS) antenna system including at least one transmit antenna and at least one amorphous core receiver antenna adapted for installation on the floor, in the grout region of the floor, or under the flooring of a passageway. An EAS system including at least one perimeter loop antenna adapted to extend around the entire perimeter of a passageway is also provided. The system may further include at least one floor antenna adapted for installation within a region of a floor of a passageway and at least one ceiling antenna adapted for installation adjacent a ceiling of the passageway.

Abstract: An EAS transmitter for generating an EAS transmission with a preselected guardband, comprises an oscillator for generating a fundamental frequency pulsed waveform and circuitry for effecting spectral window shaping of the fundamental frequency waveform on a time basis corresponding with the guardband for reducing sidelobe energy in the guardband. The transmitter may further include circuitry operative on the spectral window-shaped fundamental frequency waveform for further reducing sidelobe energy of the spectral window-shaped fundamental frequency waveform in frequency correspondence with the guardband. Another EAS transmitter comprises a storage unit having stored therein the sidelobe energy-reduced spectral window-shaped fundamental frequency waveform and obtaining EAS transmissions by use of the stored contents of the storage unit.

Abstract: An apparatus for synchronized operation of a plurality of EAS systems. The system includes two or more EAS systems. Each EAS system has a receiver for receiving the same RF synchronization signal sent from a remote source, a transmitter for transmitting a marker exciter pulse and an exciter pulse receiver. The transmitter and exciter pulse receiver of each of the EAS systems are selectively enabled a predetermined time after receiving the RF synchronization signal so that all EAS systems in a localized area can be synchronized with one another.
