Abstract
The invention relates to antennae, in particular to a low-frequency planar antenna within the frequency band range of 824 MHZ - 960 MHZ. The front-to-rear ratio of existing low-frequency planar antennae can not meet current requirements. The low-frequency planar antenna with wavy side edges comprises an antenna base plate (1) and the two side edges (2) and is characterized in that the ends, not in contact with the antenna base plate (1), of the two side edges (2) are wavy, and the front-to-rear ratio is over 25db when wave crest distance is 80 mm and distance difference between wave crest and wave trough is 5 mm. According to the low-frequency planar antenna with wavy side edges, the front-to-rear ratio far surpasses the national standard, the structure is simple, and machining is easy.
Description
Technical field
the present invention relates to antenna, be in particular the low frequency plate aerial of 824MHZ-960MHZ frequency range.
Background technology
for low frequency plate aerial, the front and back ratio of antenna for base station national standard is for being more than or equal to 16db, low frequency is 824MHZ-960MHZ frequency range, low frequency is usually used in 4G network and along with the development in epoch, now a lot of situations are the next improves network quality, before and after needing, be more than or equal to 20db than reaching, even also require to be more than or equal to 25db.The structure of general plate aerial is that base plate adds two sides.
Summary of the invention
1, technical problem to be solved:
Existing low 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, improve the front and back ratio of low-frequency antenna, the invention provides a kind of low frequency plate aerial of waveform side, comprise Antenna baseplate and two sides, two sides and the discontiguous one end of Antenna baseplate are waveform.
Described low frequency is 824MHZ-960MHZ.
Waveform in described two sides is symmetrical.
The peak-to-peak distance of described corrugated ripple is 70-90 millimeter.
The peak-to-peak distance of described corrugated ripple is 80 millimeters.
Described waveform crest and trough distance differ 4-6 millimeter.
Described waveform crest and trough distance differ 5 millimeters.
3, beneficial effect:
Low frequency plate aerial provided by the invention, simple in structure, handling ease, than reaching 25db, far above national standard, adapts to existing demand before and after optimum state substantially.
Brief description of the drawings
Fig. 1 is plate aerial vertical view.
Fig. 2 is side plate waveform schematic diagram of the present invention.
Embodiment
Describe the present invention below by embodiment.
Embodiment 1
Existing plate aerial, it is all the structure that Antenna baseplate adds dual-side, and for low frequency plate aerial, the particularly plate aerial of 824MHZ-960MHZ, the length of Antenna baseplate 1 is 1200 millimeters to 2800 millimeters, width is 300 millimeters-350 millimeters, and it is fixing that the height of side is 50 millimeters, and the thickness of aluminium sheet is 2 millimeters.
Contact one end and be processed as waveform at side 2 Antenna baseplate 1 of getting along well.Test shows, as long as the upper end of side 2 is waveform, front and back ratio has one and promotes relative national standard, at least reaches 18db.
More obvious in the time of the waveform symmetry of two sides, can reach 20db.
In research process, corrugated crest distance is studied, be between 70-90 millimeter time in crest distance, front and back are than breakthrough 20db, and last in 80 millimeters, front and back ratio reaches 23db.
To the range difference research experiment of corrugated crest and trough, be to be between 4-6 millimeter at range difference, front and back are than breaking through 20db, and time the best of 5 millimeters, front and back ratio reaches 23db.
In conjunction with the range difference of distance between crest and Wave crest and wave trough, be 80 millimeters in crest distance, when Wave crest and wave trough range difference is 5 millimeters, front and back ratio has exceeded 25db.
Can see by embodiment, the structure of low frequency plate aerial provided by the invention, compare considerably beyond national standard front and back, 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; can make various changes or retouch from working as, what therefore protection scope of the present invention should be defined with the application's claim protection range is as the criterion.
