Classification: CPC H | IPC H

Claim 0:
1. A single-frequency circular polarization positioning antenna, comprising:
an inverted F antenna, wherein the inverted F antenna is provided with a first long edge, a feed end and a first ground end; a distance from the feed end to a tail end of the first long edge is shorter or longer than a distance from the first ground end to the tail end of the first long edge; and
a parasitic antenna, wherein the parasitic antenna is coupled to the tail end of the first long edge; the parasitic antenna is arranged on one side of the tail end of the first long edge; the inverted F antenna and the parasitic antenna form an angle; wherein the angle ranges from 70° to 110°;
wherein when the inverted F antenna and the parasitic antenna resonate near a working frequency point, electrical signals on the inverted F antenna and the parasitic antenna are equal in amplitude, and a phase difference is 90°.
