Patent ID: 8736454

Claim:
A security system, comprising: a security tag comprising a transmitter and a first receiver; a phased multiple quadrature antenna in communication with said first receiver; a second receiver in communication with said transmitter; a hub in communication with said second receiver; and one or more computers in communication with said second receiver and said hub, wherein said phased multiple quadrature antenna further comprises at least two phased antenna elements in a spatially oriented configuration in an antenna plane, and at least two independently phased excitation sources coupled to each of said at least two phased antenna elements; wherein said at least two phases antenna elements are arranged orthogonally; wherein said spatial orientation includes a resultant magnetic vector within a defined tag activation zone; and wherein a resultant activation field is a uniform strength received signal at said security tag throughout a full 360 degree rotation within a single tag plane defined generally parallel to said antenna plane.
