Abstract
The utility model relates to antenna, is in particular the high frequency flat plate antenna of 2500MHz-2700MHz frequency range.Than relative to existing, the front and back of existing high frequency flat plate antenna require that some falls behind, the utility model provides a kind of high frequency flat plate antenna of zigzag side, comprise Antenna baseplate (1) and two sides (2), it is characterized in that: two sides (2) and Antenna baseplate (1) discontiguous one end are zigzag.The structure of the high frequency flat plate antenna that the utility model provides, front and back ratio exceedes national standard, and structure is simple, handling ease.
Description
technical field
the utility model relates to antenna, is 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 ratio of antenna for base station national standard is for being more than or equal to 16db, and high frequency is 2500MHZ-2700MHZ frequency range, having wide range of applications of high frequency, the existing front and back that need under many circumstances are more than or equal to 20db than reaching.The structure of general plate aerial is that base plate adds two sides.
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, improve the front and back ratio of low-frequency antenna, the utility model provides a kind of high frequency flat plate antenna of zigzag side, comprises Antenna baseplate and two sides, and 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:
The high frequency flat plate antenna that the utility model provides, structure is simple, handling ease, than reaching 23db before and after optimum state, the existing demand of basic adaptation.
Accompanying drawing explanation
Fig. 1 is plate aerial vertical view.
Fig. 2 is the utility model side plate zigzag schematic diagram.
Embodiment
Below by embodiment, the utility model is described in detail.
Embodiment 1
Existing plate aerial, it is all the structure that Antenna baseplate adds dual-side, and for high frequency flat plate antenna, the particularly plate aerial of 824MHZ-960MHZ, the length of Antenna baseplate 1 is 1200 millimeters to 2800 millimeters, width is 140 millimeters-160 millimeters, and the height of side is 25 millimeters is fixing, and the thickness of aluminium sheet is 2 millimeters.High frequency flat plate antenna under this conventional structure, front and back ratio is general about 16.
Contact one end be processed as zigzag at side 2 Antenna baseplate 1 of getting along well.Test shows, as long as the upper end of side 2 is zigzag, at least reaches 18db.
More obvious when the zigzag of two sides is symmetrical, can 20db be reached.
When 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 being tested, finding it is being highly that front and back are than breaking through 20db, and time the best of 3 millimeters, front and back ratio reaches 22db between 3-5 millimeter.
In conjunction with the zigzag sawtooth height of Distance geometry between adjacent two sawtooth lowest parts, 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 exceeded 23db.
Can be seen by embodiment, the structure of the high frequency flat plate antenna that the utility model provides, and structure is simple, as long as more existing architecture basics simply improves.
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.
