Abstract
A kind of plane sleeve antenna with lightning protection function of the utility model, comprising: sleeve; Substrate, substrate is arranged in sleeve; First antenna radiator is arranged on substrate, connect up along the length direction of substrate; Extension is routed on substrate, its side and sleeve connection, and side is connected with the first antenna radiator in addition; Second antenna radiator is arranged on substrate, connect up along the length direction of substrate; Second antenna radiator and the first antenna radiator interval are arranged; Be routed on substrate and sleeve connection antenna; Connecting portion is routed on substrate, through the gap the second antenna radiator and the first antenna radiator, and its one end is connected with extension, and the other end is connected with antenna ground, forms distributing point.Antenna of the present utility model is plane sleeve structure, and weld inductance at antenna with between aerial radiation portion, the coaxial line sky be connected with antenna like this affects little on antenna performance, and has the characteristic of logical direct current, so antenna has the function of lightning protection due to inductance.
Description
Technical field
The utility model relates to a kind of wireless radio frequency antenna, particularly a kind of plane sleeve antenna with lightning protection function.
Background technology
Mostly the antenna of current plane P CB form is dipole antenna or unipole antenna, and shortcoming is that the performance of antenna is very large by the impact of coaxial feeder and equipment, and different line lengths, connects different equipment, and antenna electric performance is all different.Extreme case even antenna does not work.And general sleeve antenna is nonplanar structure, realize with copper pipe, cannot lightning protection function.
Utility model content
The purpose of this utility model is to provide a kind of plane sleeve antenna with lightning protection function with the function of lightning protection.
For solving the problems of the technologies described above, a kind of plane sleeve antenna with lightning protection function of the utility model, comprising: sleeve; Substrate, described substrate is arranged in described sleeve; First antenna element, described first antenna comprises interconnective first antenna radiator and extension; Described first antenna radiator arranges on the substrate, connects up along the length direction of described substrate; Described extension connects up on the substrate, its side and described sleeve connection, and side is connected with described first antenna radiator in addition; Second antenna radiator, described second antenna radiator arranges on the substrate, connects up along the length direction of described substrate; Described second antenna radiator and described first antenna radiator interval are arranged; Antenna ground, the wiring of described antenna ground on the substrate, with described sleeve connection; Connecting portion, described connecting portion wiring on the substrate, through the gap described second antenna radiator and described first antenna radiator, its one end is connected with described extension, and the other end is connected with described antenna ground, forms distributing point.
Described connecting portion is inductance.Described substrate is pcb board.
A kind of antenna with the plane sleeve antenna of lightning protection function of the utility model is plane sleeve structure, and weld inductance at antenna with between aerial radiation portion, the coaxial line sky be connected with antenna like this affects little on antenna performance, and there is the characteristic of logical direct current, so antenna has the function of lightning protection due to inductance.
Accompanying drawing explanation
Fig. 1 is a kind of plane sleeve antenna shrapnel structure schematic diagram with lightning protection function of the utility model.
The utility model is a kind of has description of reference numerals in the plane sleeve antenna accompanying drawing of lightning protection function:
1-sleeve 2-substrate 3-first antenna radiator
4-extension 5-second antenna radiator 6-antenna ground
7-inductance 8-distributing point
Embodiment
Below in conjunction with accompanying drawing, a kind of plane sleeve antenna with lightning protection function of the utility model is described in further detail.
As shown in Figure 1, a kind of plane sleeve antenna with lightning protection function of the utility model, comprising: sleeve 1, PCB substrate 2 is arranged in sleeve 1.First antenna radiator 3 is arranged in PCB substrate 2, connect up along the length direction of PCB substrate 2, and extension 4 is routed in PCB substrate 2, and its side is connected with sleeve 1, and side is connected with the first antenna radiator 3 in addition.Second antenna radiator 5 is arranged in PCB substrate 2, connect up along the length direction of PCB substrate 2, and the second antenna radiator 5 and the first antenna radiator 3 interval are arranged.
Inductance 7 is connected with extension 4 as being welded in PCB substrate 2, through the gap the second antenna radiator 5 with the first antenna radiator 3, and the other end is connected with antenna ground 6, forms distributing point 8.Like this, feeder is little on antenna performance impact, makes it have lightning protection function.
A kind of antenna with the plane sleeve antenna of lightning protection function of the utility model is plane sleeve structure, and weld inductance at antenna with between aerial radiation portion, the coaxial line sky be connected with antenna like this affects little on antenna performance, and there is the characteristic of logical direct current, so antenna has the function of lightning protection due to inductance.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the scope of the application.
