Abstract
The invention relates to antennas, in particular to a high frequency planar antenna with a 2500MHZ-2700MHZ frequency band. The front-to-rear ratio of an existing high frequency planar antenna relatively falls behind the existing requirement. The high frequency planar antenna comprises an antenna bottom plate (1) and the two side edges (2) and is characterized in that one end, not in contact with the antenna bottom plate (1), of each of the two side edges (2) is in a sawtooth shape. According to the structure of the high frequency planar antenna, the front-to-rear ratio exceeds the national standard, and the high frequency planar antenna is simple in structure and easy to process.
Description
technical field
the present invention relates to antenna, be in particular the high frequency flat plate antenna of 2500MHZ-2700MHZ frequency range.
Background technology
for high frequency flat plate antenna, the front and back of antenna for base station national standard are than for being more than or equal to 16db, and high frequency is 2500MHZ-2700MHZ frequency range, the having wide range of applications of high frequency, 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.
Technical scheme:
In order to overcome the above problems, improve the front and back ratio of low-frequency antenna, the invention provides a kind of high frequency flat plate antenna of zigzag side, comprise Antenna baseplate and two sides, two sides and the discontiguous one end of Antenna baseplate are zigzag.
Described low frequency is 2500MHZ-2700MHZ.
Zigzag in described two sides is symmetrical.
Distance between described zigzag adjacent two sawtooth lowest parts is 25-35 millimeter.
Distance between described zigzag adjacent two sawtooth lowest parts is 30 millimeters.
The height of described zigzag sawtooth is 3-5 millimeter.
The height of described zigzag sawtooth is 3 millimeters.
2, beneficial effect:
High frequency flat plate antenna provided by the invention, simple in structure, handling ease, than reaching 23db, higher than national standard, adapts to existing demand before and after optimum state substantially.
Accompanying drawing explanation
Fig. 1 is plate aerial vertical view.
Fig. 2 is side plate zigzag schematic diagram of the present invention.
Embodiment
Below by embodiment, describe the present invention.
Embodiment 1
Existing plate aerial, it is all the structure that Antenna baseplate adds dual-side, and for high frequency flat plate antenna, the plate aerial of 824MHZ-960MHZ particularly, the length of Antenna baseplate 1 is 1200 millimeters to 2800 millimeters, width is 140 millimeters-160 millimeters, and it is fixing that the height of side is 25 millimeters, and the thickness of aluminium sheet is 2 millimeters.High frequency flat plate antenna under this conventional structure, front and back ratio is generally in 16 left and right.
In side 2 discord Antenna baseplate 1 contact one end, be processed as zigzag.Test shows, as long as the upper end of side 2 is zigzag, front and back ratio has one and promotes relative national standard, at least reaches 18db.
More obvious when the zigzag symmetry of two sides, can reach 20db.
When the distance between zigzag adjacent two sawtooth lowest parts is 25-35 millimeter, front and back are than breaking through 20db, and last in 30 millimeters, front and back ratio reaches 22db.
Zigzag sawtooth height is tested, found between 3-5 millimeter, be highly, front and back are than breaking through 20db, and time the best of 3 millimeters, front and back ratio reaches 22db.
In conjunction with the distance between adjacent two sawtooth lowest parts and zigzag sawtooth height, the distance between zigzag adjacent two sawtooth lowest parts is 30 millimeters, and when zigzag sawtooth height is 3 millimeters, front and back ratio has surpassed 23db.
By embodiment, can see, the structure of high frequency flat plate antenna provided by the invention, front and back ratio surpasses national standard, and simple in structure, as long as simply improve on existing architecture basics, but effect is huge again.
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.
