The radiating element includes the semicircle silver-plated polyester film of top half, is arranged at the rectangle plating of the latter half
Silver-colored polyester film group and the feeding portion being arranged at below the silver-plated polyester film group of rectangle；The silver-plated polyester film group of the rectangle
By the silver-plated polyester film A of the rectangle set gradually from top to bottom, the silver-plated polyester film B of rectangle, the silver-plated polyester film C of rectangle and square
The silver-plated polyester film D compositions of shape, and the height of four silver-plated polyester films of rectangle from top to bottom and width are gradually reduced, and make square
The silver-plated polyester film group of shape is stepped in quadravalence；It is silver-plated poly- that the length of the silver-plated polyester film A of rectangle is more than the semicircle
The diameter of ester film；
The earth plate is the silver-plated polyester film E of rectangle, its height is less than substrate height.
Further, the radiating element and the earth plate are made by silver-plated polyester film AgHT-8.
Further, the height of the earth plate is less than the half of substrate height.
Further, the substrate is pet substrate.
Further, the height of the substrate is 45mm, width 20mm, thickness 1mm；The silver-plated polyester of semicircle
The radius of film is 10.5mm；The height of the silver-plated polyester film A of rectangle is 10.5mm, width 23mm；The rectangle plating
The height of silver-colored polyester film B is 3.3mm, width 16mm；The height of the silver-plated polyester film C of rectangle is 2.3mm, and width is
12mm；The height of the silver-plated polyester film D of rectangle is 1mm, width 6mm；The height of the earth plate is 17mm, and width is
30mm；The width of the feeding portion is 2mm.
Beneficial effects of the present invention：Compared with prior art, the invention has the advantages that：
1）The volume that the size of the antenna of the present invention only has, can but realize the band of 2.36GHz-7.5GHz (5.14GHz)
It is wide.
2）The antenna top half of the present invention employs semicircular structure, and to improve antenna radiation performance, the latter half is adopted
With ladder technology, level Four ladder is make use of to obtain the ultrabroad-band spectrum more widened.
3）The antenna of the present invention uses silver-plated polyester film AgHT-8, and antenna is transparent, and more conventional antenna has
Stronger concealment.
