The invention discloses an unmanned aerial vehicle range extending antenna covering a WIFI frequency band. The unmanned aerial vehicle range extending antenna comprises a substrate, a signal line, a symmetrical oscillator, a stepped coplanar strip line, a director and a reflector, the stepped coplanar strip line extends along the center line direction of the substrate; one end of the signal line is provided with a feed port for loading working current, and the other end of the signal line is connected with the stepped coplanar strip line; the symmetrical dipoles are connected with the stepped coplanar strip line; the symmetrical dipoles are provided with two long symmetrical dipoles and two short symmetrical dipoles; the reflector is connected with the stepped coplanar strip line; a gap is formed between the director and the short symmetrical dipole, and the director and the reflector are respectively positioned at two ends of the symmetrical dipole; when the antenna works, the working current is divided into two parts of current, and electromagnetic waves are radiated outwards through the dipoles. When the antenna works in different frequency bands, the long symmetrical dipoles and the short symmetrical dipoles play different roles. The antenna provided by the invention can realize excellent performances of double frequency, wide frequency band, high gain and low reflection coefficient.
