Description
Technical field
The utility model relates to antenna technical field, particularly relates to a kind of passive high-gain aerial.
Background technology
Received signal strength antenna generally can be divided into active antenna and the large class of passive antenna two, and low power electric appliance, such as mobile phone, router etc. generally use passive antenna.Passive antenna generally comprises a metal radiation body and a reflecting plate.Metal radiation body generally has specific shape with to the electromagnetic wave modulation be radiated on it, and the spacing of the shape of metal radiation body and metal radiation body and reflecting plate becomes the key factor affecting passive antenna gain.
Existing passive antenna, such as publication number is the Chinese patent " plate aerial " of CN203326107U, and the complex structure of its metal radiation body, gain is lower.
How to design that a kind of structure is simple and gain is high passive antenna becomes problem demanding prompt solution.
Summary of the invention
Technical problem to be solved in the utility model is, for the above-mentioned deficiency of prior art, proposes the simple and passive high-gain aerial that gain is high of a kind of structure.
The technical scheme that the utility model solves the employing of its technical problem is that propose a kind of passive high-gain aerial, it comprises metal radiation body, reflecting plate spaced with metal radiation body; Described metal radiation body offers the groove in " recessed " font, described groove comprises the first vertical groove, the second vertical groove and is communicated with the horizontal groove of the first vertical groove and the second vertical groove; Described first vertical groove and the second vertical groove length are 95-105 millimeter, and width is 20-30 millimeter; Described horizontal groove length is 125-135 millimeter, and width is 17-18 millimeter.
Further, the spacing of described metal radiation body and described reflecting plate is 32-38 millimeter.
Further, described reflecting plate both sides are inclined upwardly and extend to form flange, and described flange seals by cover plate, and cover plate, flange and reflecting plate form accommodation space, and metal radiation body is positioned at this accommodation space.
Further, also comprise rotary shaft rack, described rotary shaft rack comprises rotating shaft, is positioned at the column switching part at rotating shaft two ends, the support be connected with rotating shaft lateral wall; Described support comprises two symmetrically arranged sides, the base arcuate edge caved inward, by the base plate that dual-side and base basal surface connect; Described base plate is provided with many reinforcements, described reinforcement one end is connected to side, and the other end is connected to base.
Further, offer bar shaped slot in the middle part of described reflecting plate, two articulated parts are fixed on bar-shaped trough both sides, and described articulated part inner surface is formed with rotation groove, and described column switching part is plugged in and rotates in groove.
The utility model makes the passive antenna be made up of this metal radiation body and reflecting plate have higher gain by the shape of specific design metal radiation body and size.The utility model is also provided with carrying structure simultaneously, makes the utility model passive antenna be easy to carry and hang.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of the passive high-gain aerial of the utility model;
Fig. 2 is the front schematic view of metal radiant panel in the passive high-gain aerial of the utility model;
Fig. 3 is the perspective view of the utility model passive high-gain aerial shaft support.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Please refer to Fig. 1-Fig. 3, the passive high-gain aerial of the utility model it comprise metal radiation body 100, reflecting plate 200 spaced with metal radiation body; Metal radiation body 100 offers the groove in " recessed " font, groove comprises the first vertical groove 120 of vertical groove 110, second and is communicated with the horizontal groove 130 of the first vertical groove 110 and the second vertical groove 120.
First vertical groove 110 and the second vertical groove 120 length are 95-105 millimeter, and width is 20-30 millimeter; Horizontal groove 130 length is 125-135 millimeter, and width is 17-18 millimeter.
After the metal radiation body of above-mentioned shape and size makes electromagnetic wave modulated, there is higher gain.
Due to electromagnetic wave modulated by metal radiation body after also need through baffle reflection, the gap between reflecting plate and metal radiation body is also the important parameter affecting antenna gain.In the present embodiment, the spacing between metal radiation body and reflecting plate is 32-38 millimeter, makes the antenna in the present embodiment have better gain.
Preferably, please refer to Fig. 1, Fig. 3, for making the antenna of the application, there is better portability, the application is also inclined upwardly in reflecting plate 200 both sides and extends to form flange 210, described flange 210 seals by cover plate (not shown), cover plate, flange 210 and reflecting plate 200 form accommodation space, and metal radiation body 100 is positioned at this accommodation space.Sealing accommodation space can effectively be avoided when antenna is for outdoor, and what metal radiation body may be subject to exposes to wind and rain and affect antenna gain.
Further, when the antenna of the application is used for indoor, for ease of laying, be also provided with rotary shaft rack 300, described rotary shaft rack 300 comprises rotating shaft 310, is positioned at the column switching part 320 at rotating shaft two ends, the support 330 be connected with rotating shaft lateral wall; Described support 330 comprises two symmetrically arranged sides 331, the base arcuate edge 332 caved inward, by the base plate 333 that dual-side and base basal surface connect; Described base plate is provided with many reinforcements 334, described reinforcement 334 one end is connected to side 331, and the other end is connected to base 332.
For coordinating rotary shaft rack 300 to rotate, in the middle part of reflecting plate 200, also offer bar shaped slot 220.Two articulated parts 400 are fixed on bar-shaped trough 220 both sides.Articulated part 400 inner surface is formed and rotates groove 410, and column switching part 320 is plugged in and rotates in groove 410.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
