The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, the present invention provides a kind of plane bipyramid ultra-wideband antenna with peripheral minor matters and additional minor matters, packet
The periphery of the plane double-cone antenna ontology 8 for including substrate 1 and being fixed on substrate, the plane double-cone antenna ontology 8 is equipped with
Peripheral minor matters, the periphery minor matters include 4 minor matters units, and the minor matters unit is symmetrically distributed in the two of the antenna body 8
Side, is equipped with additional minor matters between the minor matters unit and the antenna body 8, the additional minor matters include 2 minor matters one and 2
Minor matters two, 2 minor matters one are distributed on 2 diagonal minor matters units, and 2 minor matters two are distributed in remaining 2 branch
It saves on unit；The minor matters unit includes one section 2 and two section 3, the height of one section of 2 cone perpendicular to antenna body 8, and institute
