Utility model content
1, technical problem to be solved:
Existing intermediate frequency plate aerial is lower than national standard due to front and back, can not meet existing demand.
Technical scheme:
In order to overcome the above problems, the utility model provides the intermediate frequency plate aerial with high front and back ratio, comprise Antenna baseplate 1 and side 2, side 2 is positioned at Antenna baseplate (1) both sides, be fixedly connected with Antenna baseplate 1, the side 2 of the every side of Antenna baseplate 1 is two, the height of two sides 2 is not identical, the height of two sides 2 of the every side of Antenna baseplate 1 is not identical, the aspect ratio inboard side edge 4 of outboard side edge 3 is high, and wherein every side of Antenna baseplate has at least the top of 1 side to be continuous triangle shape.
Described intermediate frequency is 1710MHZ-2500MHZ.
Continuous triangle shape in the side 2 of the both sides of described Antenna baseplate 1 is symmetrical.
Described triangle is right-angled triangle.
The length at two ends at a right angle is respectively 38-42 millimeter, 3-5 millimeter, and that long one end and side 2 upper end lines overlap.
The length at two ends at a right angle is respectively: 40 millimeters, 4 millimeters.

Beneficial effect:
The intermediate frequency plate aerial that the utility model provides, structure is simple, handling ease, than reaching 30db before and after optimum state, far away higher than national standard, the existing demand of basic adaptation.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model.
Fig. 2 is front view of the present utility model
Fig. 3 is the utility model continuous triangle shape schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Existing plate aerial, it is all the structure that Antenna baseplate adds dual-side, and for intermediate frequency plate aerial, the particularly plate aerial of 1710MHZ-2500MHZ, the length of Antenna baseplate 1 is 1200 millimeters to 2800 millimeters, width is 200 millimeters of-240 millimeters of rice, and the height of side is 30 millimeters is fixing, and the thickness of aluminium sheet is 2 millimeters.Intermediate frequency plate aerial under this conventional structure, front and back are than generally between 16-18db.
The intermediate frequency plate aerial that the utility model provides, there are two sides every side of Antenna baseplate, outboard side edge 3 and inboard side edge 4, and the height of two sides is unequal, and outboard side edge 3 is higher than inboard side edge 4.Such structure, same to overtesting, the front and back tested out ratio reaches more than 22db.
Different in the spacing of outboard side edge 3 and inboard side edge 4, front and back are more different than also, can arrive 22-23db in the scope of 3-5 millimeter, than the highest before and after in 3 millimeters, are 24db.
Between outboard side edge 3 and inboard side edge 4, difference in height is the same, and front and back are more different than also, can arrive 22-23db in the scope of 24-26 millimeter, than the highest before and after in 25 millimeters, is 24db.
Be 25 millimeters at outboard side edge 3 and inboard side edge 4 difference in height, when the distance of outboard side edge 3 and inboard side edge 4 is 3 millimeters, front and back ratio reaches more than 26db.
Contact one end be processed as continuous triangle shape at side 2 Antenna baseplate 1 of getting along well.Test shows, as long as the upper end of side 2 is continuous triangle shape, front and back ratio has one and promotes relative national standard.
It is more obvious when the continuous triangle shape of two sides is symmetrical.
Are right-angled triangle at described triangle, and in both sides at a right angle, upper end lines that are long and side overlap, but two right-angle sides are respectively at 38-42 millimeter, during 3-5 millimeter, in test at least before and after than reaching 25db.
When two right-angle sides are respectively 40 millimeters, 4 millimeters, than at least reaching 26db in test
Indices all selects preferably, is 3 millimeters in the spacing at outboard side edge 3 and inboard side edge 4, and outboard side edge 3 is higher than inboard side edge 4 25 millimeters, side top is continuous triangle shape, and triangle is right-angled triangle, when two right-angle sides are respectively 40 millimeters, 4 millimeters, front and back ratio reaches 30db.
Can be found out by above data, the structure of the intermediate frequency plate aerial that the utility model provides, front and back ratio exceedes national standard, and structure is simple, as long as more existing architecture basics simply improves, but successful.
Although the utility model with preferred embodiment openly as above; but they are not of the present utility model for limiting; anyly have the knack of this those skilled in the art; not departing from the spirit and scope of the utility model; can make various changes or retouch from working as, what therefore protection range of the present utility model should define with the claims of the application is as the criterion.
