Abstract
An antenna system for use with very low frequency or low frequency RF tags include a plurality of ferrite core coils disposed at an angle with respect to each other. The antenna system further includes a secondary coil disposed around at least one of the primary coils. The antenna system can provide a multi-axis antenna including two, three, or more than three antenna elements. The antenna system can be disposed in a gang box for a less aesthetically intrusive installation.
