The beneficial effects of the utility model are as follows: the 4G full-band antenna widens the low frequency band to 700-960MHz, and has small area and small size.
Description
Technical Field
The utility model relates to the technical field of antennas, in particular to a 4G full-band antenna.
Background
Under the prior art, the antenna area can only reach 800-960MHz under the same condition, and the requirement of a user can not be met.
Disclosure of Invention
In order to solve the problem that the low-frequency bandwidth of an antenna in the prior art is not wide enough, the utility model provides a 4G full-band antenna, which comprises a PCB (printed circuit board), and a feeder line and a ground feeder line which are arranged on the PCB, wherein the ground feeder line surrounds the feeder line.
As a further development of the utility model, the ground feed line is provided with a notch, the ground feed line being semi-enclosed in the feed line.
As a further improvement of the utility model, the PCB is a single-sided PCB.
As a further development of the utility model, the feed line is provided with a first feed point region.
As a further development of the utility model, the ground feed line is provided with a second feed point region.
As a further improvement of the utility model, the ground feed line has a gap with the feed line.
The beneficial effects of the utility model are as follows: the 4G full-band antenna widens the low frequency band to 700-960MHz, and has small area and small size.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
As shown in fig. 1, the utility model discloses a 4G full-band antenna, which comprises a PCB board 1, and a feeder line 2 and a ground feeder line 3 arranged on the PCB board 1, wherein the ground feeder line 3 surrounds the feeder line 2.
The ground feed line 3 is used to couple low frequencies and adjust the thickness and length of the feed line 2 to control high frequencies. The ground feed 3 surrounds the feed 2 and the low frequency is adjusted by adjusting the distance and length so that the bandwidth of the coupled low frequency is much wider than in the prior art.
As a preferred embodiment of the present utility model, the ground feeder 3 is provided with a notch 4, and the ground feeder 3 is semi-enclosed in the feeder 2; the PCB 1 is a single-sided PCB.
The feeder line 2 is provided with a first feed point region 21 and the ground feeder line 3 is provided with a second feed point region 31.
A gap is formed between the ground feeder 3 and the feeder 2, and the ground feeder 3 and the feeder 2 are not in contact with each other.
In summary, the utility model is coupled by the ground feed line 3 and the feed line 2, the low frequency bandwidth of the antenna is much wider than the prior art, and the requirements of users are met.
The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
