Abstract:
An electronic article surveillance antenna, comprising a first coil defined by a first plurality of windings of a first wire, said first coil having a first end and a second end, wherein a cross-section of said first coil varies from said first end to said second end, the cross-section defined by the number of windings of the first wire per a layer of said first coil and the number of said layers per end;a second coil defined by a second plurality of windings of a second wire, said second coil having a first end and a second end, wherein a cross-section of said second coil varies from said first end to said second end, the cross-section of said second coil defined by the number of windings of the second wire per a layer of said second coil and the number of said layers per end, wherein said first ends of said first and said second coils being thinner than said second ends of said first and said second coils, said first and said second coils disposed in overlapping orientation with each other near said first ends, wherein said antenna is relatively uniform in thickness.
