Refer to shown in Fig. 2, the supporting body 1 is working of plastics, is extended along longitudinally, rectangular setting.The carrying
Body 1 is used to support the antenna body 2 with the separator 4.
The antenna body 2 includes the grounding parts 20 being extended along longitudinally, the company being extended from grounding parts 20
Socket part 21 and the Department of Radiation 22 being further extended from connecting portion 21.The connecting portion 21 is included from one end of grounding parts 20
Bent with along institute in 90 degree along the extended vertical section of the vertical direction perpendicular to the longitudinally and with vertical section
State the extended lengthwise section of longitudinally.The lengthwise section forms a slit with the grounding parts 20.The Department of Radiation 22 is wrapped
The first paragraph and first paragraph that further extend along longitudinally from the lengthwise section of the connecting portion 21 are included in 90 degree of bendings with edge
Second segment that the vertical direction extends and from second segment end in 90 degree of back bending with extend along the longitudinally the
Three sections.Three sections of the Department of Radiation 22 are generally U-shaped with the lengthwise section of connecting portion 21.The U-shaped opening is towards the lengthwise
Direction.The antenna body 2 is in the size on longitudinally more than it in the size on vertical direction.
The heart yearn 31 of the feeder line 3 is connected to the junction of the connecting portion 21 and the Department of Radiation 22, to form signal
Load point.The braiding layer 32 of the feeder line 3 is connected with the grounding parts 20 of antenna body 2, to form earth point.
The separator 4 is roughly the same with the shape of the antenna body 2, and the separator 4 includes prolonging along longitudinally
The separator grounding parts 40 of setting, the joint portion 41 that the one end of self-isolation part grounding parts 40 extends and the end of self-bonding portion 41 is stretched to prolong
Stretch the arm 42 of setting.The arm 42 is U-shaped, with two-end-point, one towards the longitudinally is formed between the two-end-point
