Antenna feed point and the grounding parts are located at the same side of the radiant body, and the radiant body includes：Sawtooth spoke
Penetrate portion, the sawtooth Department of Radiation is sawtooth radiant section, the sawtooth radiant section is serrated projection；
First connecting portion, connects the grounding parts and second connecting portion, and parallel with sawtooth Department of Radiation；Second connects
Socket part, connects the first connecting portion and the sawtooth Department of Radiation；3rd connecting portion, connects the sawtooth
Department of Radiation and the antenna feed point.
It is further characterized by described grounding parts L-shaped, and antenna feed point is in same level.
It is further characterized by the grounding parts, between antenna feed point and radiant body, forms clearance zone.
It is further characterized by the same table that the grounding parts, antenna feed point and radiant body may be contained within substrate
Face.
It is middle narrow right-angled trapezium to be further characterized by the first connecting portion.
In being further characterized by the sawtooth Department of Radiation, the another side relative with sawtooth radiant section is dashed forward for rectangle
Rise.
The antenna feed point is further characterized by for rectangular shape.
It is further characterized by the antenna feed point and the L-shaped connection of the 3rd connecting portion.
It is further characterized by the grounding parts and the L-shaped connection of first connecting portion.
Beneficial effects of the present invention are：High gain, good directionality, and antenna performance will not be with outer collarettes
Border changes and deteriorates, and has advantage of lower cost, efficiency high.
