Abstract
An antenna device configured for wireless positioning. The antenna device includes a ground plane having a polygonal shape comprising at least 4 side edges. A plurality of chip antenna elements tuned to a predetermined radio frequency are each singly provided at one of said side edges with a spacing between adjacent ones of said chip antenna elements corresponding to ½ of a wavelength of said predetermined radio frequency. A patch antenna element tuned to said predetermined radio frequency is provided at a center portion of a front side of the ground plane.

An antenna device configured for wireless positioning, comprising:
- a ground plane having a polygonal shape comprising at least 4 side edges;
- a plurality of chip antenna elements tuned to a predetermined radio frequency, wherein each chip antenna element is singly provided at one of said side edges with a spacing between adjacent ones of said chip antenna elements corresponding to ½ of a wavelength of said predetermined radio frequency;
- a patch antenna element tuned to said predetermined radio frequency, provided at a center portion of a front side of the ground plane;
- and
- a notch formed at each intersection of side edges of the ground plane to separate adjacent side edges of the ground plane, wherein each notch extends a distance corresponding to ¼ of said predetermined wavelength.
