Description
Technical field
This utility model relates to field of antenna, is specifically related to a kind of multifrequency antenna.
Background technology
Mostly current all of antenna for mobile phone is 3G mobile antenna or the antenna of covering part LTE frequency range, and as a example by domestic China extremely joins, it is very poor that most type receiving efficiency 2600MHz when can become, and often only has about-88.
Summary of the invention
The purpose of this utility model is the defect for prior art and deficiency, a kind of multifrequency antenna is provided, the bandwidth making high frequency by the way of increasing passive antenna achieves all standing from 1710MHz until 2690MHz, and the efficiency of 2690MHz can reach the yield value of more than 1db.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of multifrequency antenna, including: the main feed point being connected by flexible PCB, first ground feed point, second ground feed point, the low frequency part of antenna, the first spoke side of antenna HFS, second spoke side of antenna HFS, passive antenna, the second spoke side of described antenna HFS is connected by coupling with described passive antenna, and described passive antenna is connected with described second ground feed point.
Further, it is provided with the capacitive slot area for controlling bandwidth between low frequency part and second spoke side of antenna HFS of described antenna.
Further, described antenna is mobile phone full range antenna.
Further, the frequency of the low frequency part of described antenna is 800-900MHz, the frequency of the first spoke side of described antenna HFS is 1710MHz-2170MHz, the frequency of the second spoke side of described antenna HFS is 2300MHz, and the frequency after the second spoke side of described antenna HFS couples with described passive antenna is 2600MHz.
After using said structure, this utility model has the beneficial effect that a kind of multifrequency antenna of the present utility model, the bandwidth making high frequency by the way of increasing passive antenna achieves all standing from 1710MHz until 2690MHz, and the efficiency of 2690MHz can reach the yield value of more than 1db.
