Patent abstract
A multi-coil antenna array constructed with a tuned transformer to null mutual inductance. First and second antenna coil halves are displaced longitudinally on opposite sides of a pathway along which ID tags pass, for example, a chute assembly. The planar coils are displaced at a selected angular orientation and driven with inputs having a 90° phase differential to create an intermediate vertical field with a vertical axis of rotation. Identification data stored in tags attached to animate or inanimate objects passing through the field is interrogated, such as data identifying people, animals, inventory or any other parameters of interest.
