    摘要: An EAS antenna having uniform antenna thickness along the antenna height is provided. The antenna is contains at least two overlapping coils where the individual coil cross-sections are variable with respect to the circumference. If the individual coil thickness is halved at the overlap, the antenna will have uniform thickness along the antenna height. This is accomplished by reducing the number of wire turns per layer along one or more sections of the coil, and simultaneously increasing the number of wire layers on the same sections.

    摘要: Systems and methods for operating a security tag (132, 300). The methods comprise: wirelessly receiving at the security tag a signal sent from a remote device (104, 190); and preventing alarm issuance when first and second Magnetic Attracting (“MA”) halves (302, 312, 702, 704) of the security tag are pulled apart by deactivating alarm circuitry (264, 340) internal to the security tag in response to the security tag's reception of the signal.
