Beschreibung
Zusammenfassung:	The utility model discloses a Bluetooth positioning antenna and a wireless positioning system with the Bluetooth positioning antenna, the Bluetooth positioning antenna comprises a dielectric substrate, a plurality of circular radiation units are annularly distributed around the center of the dielectric substrate to form an antenna array, and the circular radiation units are connected with a driving control unit through two feeding points; wherein the circular radiation units are orthogonal polarization radiation units, and the distance between the adjacent circular radiation units is not greater than half of the shortest wavelength for receiving or transmitting electromagnetic waves; in this way, the driving control unit receives electromagnetic waves through the antenna array, and therefore positioning of the generating end is completed; namely, the Bluetooth positioning antenna adopts the circular radiation unit, has smaller area and higher phase stability and channel isolation, and can effectively improve
