Claim 9:
10. A UAV, having a substrate disposed therein, the substrate having an antenna disposed thereon, the antenna comprising:
a first antenna unit; and
a second antenna unit, the first antenna unit and the second antenna unit being disposed on the same surface of a substrate; wherein
the first antenna unit comprises a first primary radiation unit and a first secondary radiation unit, and the second antenna unit comprises a second primary radiation unit and a second secondary radiation unit, a gap existing between the first primary radiation unit and the second primary radiation unit; and
the first secondary radiation unit is connected to one end of the first primary radiation unit that is away from the second primary radiation unit, the second secondary radiation unit is connected to one end of the second primary radiation unit that is away from the first primary radiation unit, and the first secondary radiation unit and the second secondary radiation unit are located on the same side of the substrate;
the first primary radiation unit is an inverted trapezoidal structure, the second primary radiation unit is a trapezoidal structure, the first secondary radiation unit is formed by extending horizontally one of top corners of the inverted trapezoidal structure, and the second secondary radiation unit is formed by extending obliquely upward one of bottom corners of the trapezoidal structure.
