Abstract
The invention relates to antennas, in particular to an intermediate-frequency planar antenna at the frequency band ranging from 1710 MHZ to 2500 MHZ. The current requirements can not be met due to the fact that the front-to-rear ratio of an existing intermediate-frequency planar antenna is lower than the national standard. The two-side-edge intermediate-frequency planar antenna comprises an antenna bottom board (1) and side edges (2). The side edges (2) are located on the two sides of the antenna bottom board (1) and fixedly connected with the antenna bottom board (1). The two-side-edge intermediate-frequency planar antenna is characterized in that each side of the antenna bottom board (1) is provided with two side edges (2) of different heights, and the height of outer side edges (3) is larger than that of inner side edges (4). According to the two-side-edge intermediate-frequency planar antenna of the structure, the front-to-rear ratio exceeds the national standard, the structure is simple, only simple improvement needs to be conducted on the basis of an existing structure, and the effect is remarkable.
Description
Technical field
The present invention relates to antenna, be in particular the intermediate frequency plate aerial of 1710MHZ-2500MHZ frequency range.
Background technology
For intermediate frequency plate aerial, the front and back of antenna for base station national standard ratio is for being more than or equal to 16db, and intermediate frequency is 1710MHZ-2500MHZ frequency range, and the range of application of intermediate frequency is light very, and the existing front and back that need are under many circumstances more than or equal to 20db than reaching.The structure of general plate aerial is that base plate adds two sides.
Summary of the invention
1, technical problem to be solved:
Existing intermediate frequency plate aerial, because front and back are lower than national standard, can not meet existing demand.
2, technical scheme:
In order to overcome the above problems, the invention provides a kind of double side intermediate frequency plate aerial, comprise Antenna baseplate 1 and side 2, side 2 is positioned at Antenna baseplate 1 both sides, be fixedly connected with Antenna baseplate 1, it is characterized in that: the side 2 of Antenna baseplate 1 every side is two, and the height of two sides 2 is not identical, the height of two sides 2 of Antenna baseplate 1 every side is not identical, side 4 height inside the aspect ratio of outside side 3.
Described intermediate frequency is 1710MHZ-2500MHZ.
Described outside side 3 and the distance between inner side side 4 are 3-5 millimeter, are preferably 3 millimeters.
Described outside side 3 and the difference in height between inner side side 4 are 24-26 millimeter, preferably 25 millimeters.
3, beneficial effect:
Intermediate frequency plate aerial provided by the invention, simple in structure, handling ease, than reaching 25db, adapts to existing demand before and after optimum state substantially.
Accompanying drawing explanation
Fig. 1 is the vertical view of intermediate frequency plate aerial of the present invention.
Fig. 2 is the front view of intermediate frequency plate aerial of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention 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 plate aerial of 1710MHZ-2500MHZ particularly, the length of Antenna baseplate 1 is 1200 millimeters to 2800 millimeters, width is 200 millimeters-240 millimeters, and it is fixing that the height of side is 30 millimeters, 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.
As shown in Figure 1 and Figure 2, intermediate frequency plate aerial provided by the invention, every side of Antenna baseplate has two sides, outside side 3 and inner side side 4, and also the height of two sides is unequal, and outside side 3 is than inner side side 4 height.Such structure, same overtesting, more than the front and back that test out ratio reaches 20db.
Between outside side 3 and inner side side 4, distance is different, and front and back are more different than also, in the scope of 3-5 millimeter, can arrive 22-23db, and in 3 millimeters, front and back, than the highest, are 23db.
Between outside side 3 and inner side side 4, difference in height is the same, and front and back are more different than also, in the scope of 24-26 millimeter, can arrive 22-23db, and in 25 millimeters, front and back, than the highest, are 23db.
At outside side 3 and inner side side 4 differences in height, it is 25 millimeters, when the distance of outside side 3 and inner side side 4 is 3 millimeters, more than front and back ratio reaches 25db.
By above data, can find out, the structure of intermediate frequency plate aerial provided by the invention, front and back ratio surpasses national standard, and simple in structure, as long as simply improve on existing architecture basics again, but successful.
Although the present invention with preferred embodiment openly as above; but they are not of the present invention for limiting; anyly have the knack of this skill person; without departing from the spirit and scope of the invention; from when can make various changes or retouch, so being as the criterion of should being defined with the application's claim protection range of protection scope of the present invention.
