Detailed Description
The invention will now be further described with reference to the accompanying description and examples:
according to the attached drawings 1 to 5, the 5G multichannel-based large-field-angle spotlight antenna is provided with an antenna reflector plate 1, n dual-polarized oscillators 11 are arranged on the antenna reflector plate 1, the n dual-polarized oscillators 11 are averagely divided into m dual-polarized oscillator groups 12, the dual-polarized oscillator groups are arranged on the antenna reflector plate 1 in an array mode, and at least one high-frequency power divider 13 is arranged between the dual-polarized oscillators 11 in the dual-polarized oscillator groups 12. The high-frequency power divider 13 is designed corresponding to the ultrahigh-frequency level frequency band of the dual-polarized oscillator 11.
The antenna reflection plate 1 can improve the receiving sensitivity of antenna signals, the strength of the antenna is enhanced, the antenna reflection plate 1 also plays a role in blocking and shielding interference of other electromagnetic waves from the rear to the spotlight antenna signals, and the stability of the spotlight antenna signals is improved.
According to the illustration of fig. 5, the frequency band of the dual-polarized oscillator 11 is 2555-2690 MHz. The frequency band is ultrahigh frequency, is more suitable for radiation of 5G signals, and enhances the intensity of the 5G signals.
As shown in fig. 1, the distance between the dual-polarized vibrators 11 arranged in the dual-polarized vibrator group 12 is 70-120 mm. The range is the optimal range of the spacing of the dual-polarized oscillators capable of realizing the strongest signal and the most stable signal when the spotlight antenna covers 5G signals.
As shown in fig. 5, the spacing between the dual sets of vibrators 12 is 60-80 mm. The range is the optimal range for realizing the separation between the dual-polarized vibrator groups with the strongest signals and the most stable signals when the spotlight antenna covers 5G signals.
As shown in fig. 5, the dual-polarized vibrator groups 12 are staggered by the pitch of one dual-polarized vibrator 11. The distance of one dual-polarized oscillator 11 is staggered, so that the dual-polarized oscillator groups on the reflecting plate are all located at the position with the strongest radiation superposition, and the signal coverage capability of the antenna can be enhanced.
Referring to fig. 5, baffles 14 are disposed between the dual-polarized vibrator groups 12, and baffles 14 are disposed at the head and tail portions of the dual-polarized vibrator groups 12. The baffle 14 can improve the front-to-back ratio of the antenna and the convergence of the wave beam, and optimize the directivity.
As shown in fig. 6 to 7, the dual-polarized vibrator sets 12 are arranged in a horizontal array on the antenna reflection plate 1. The design of horizontal array arrangement can form half-power beam width in the vertical direction to be far larger than half-power beam width in the horizontal direction, and plays a role in strengthening the guidance of antenna radiation and amplifying electromagnetic waves.
As shown in fig. 8 to 9, the dual-polarized vibrator sets 12 are arranged in a vertical array on the antenna reflection plate 1. The vertical array arrangement design can form half-power beam width in the horizontal direction far larger than that in the vertical direction, and plays roles in strengthening antenna radiation guiding and amplifying electromagnetic waves.
As shown in fig. 7 or fig. 9, 12 dual-polarized oscillators 11 are arranged on the antenna reflection plate 1, and the 12 dual-polarized oscillators 11 are averagely divided into 4 dual-polarized oscillator groups 12, each of which is 3 dual-polarized oscillators 11.
According to the attached fig. 1, an antenna circuit board 15 is further disposed on the back of the antenna reflector to provide a connection circuit for the whole spotlight antenna.
In the field of communications, a half-power beam width means that there are usually two lobes or multiple lobes in an antenna radiation direction, wherein the largest lobe is called a main lobe, the remaining lobes are called side lobes, and an angle between two half-power points of the main lobe is defined as a lobe width of an antenna pattern, i.e., a half-power beam width. The horizontal half-power beam width is an included angle of two directions, wherein the radiation power is reduced by 3dB on the 2 side of the maximum radiation direction in the horizontal direction; the vertical half-power beam width is an included angle of 2 directions in which the radiation power is reduced by 3dB on the 2 side of the maximum radiation direction in the vertical direction.
An antenna is an energy concentrating device, with an increase in radiation in one direction meaning a decrease in radiation in the other direction; therefore, the radiation intensity in a certain direction can be enhanced by reducing the horizontal half-power beam width to increase the antenna gain. Under the condition of a certain antenna gain, the horizontal half-power beam width of the antenna is inversely proportional to the vertical half-power beam width, and the relationship can be expressed as follows: ga 10 x lg [32400/(a b) ]; wherein Ga is antenna gain, and the unit is dBi; a is the horizontal half-power beamwidth and b is the vertical half-power beamwidth in degrees.
The polarization of the antenna refers to the direction of the electric field intensity formed when the antenna radiates, and is generally divided into two modes, vertical polarization, horizontal polarization and ± 45 ° polarization.
The array of the dual-polarized oscillator is reasonable in design overall layout, optimizes the prior art, has the function of network calibration, can change the size and the direction of a beam through different weights in use to achieve the size change and the direction change of the beam, is more optimized in operation, enables the whole spotlight antenna to meet the requirements of achieving the enhanced coverage and stability of 5G signals in high-floor and high-density areas, and reduces interference.
As shown in fig. 1, the reflector antenna further includes a reflector antenna protective housing 2 and a bottom plate 3, and the reflector antenna protective housing is provided with an installation frame 21. The spot lamp antenna is generally arranged in an outdoor environment, so that the arrangement of the antenna protection shell 2 can prevent the internal components of the spot lamp antenna from being damaged due to the influence of weather factors such as wind, sunshine, rain and the like. Spotlight antenna protective housing 2 and bottom plate 3 pass through bolted connection and form inclosed space, and spotlight antenna protective housing 2 sets up in inclosed protection space, can reduce other frequency interferences in the external world. The mounting frame 21 is used for positioning a fixed position in an actual use place and adjusting the elevation angle of the spotlight antenna according to actual needs, so that the direction change of the antenna radiation is adjusted.
