Classification: CPC H | IPC H

Claim 10:
11. 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 provided with a second long edge; a tail end of the second long edge is spaced apart from and coupled with 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 electrical signals respectively loaded to the inverted F antenna and the parasitic antenna satisfy that the amplitudes are equal and a phase difference is 90°, circular polarization radiation is generated.
