Description

Technical Field

[0001] The utility model relates to the technical field of communication antennas, and more specifically, to a high-gain 5G smart antenna. Background Art

[0002] With the continuous development and application of 5G communication technology, antenna design has become increasingly important. Compared with previous communication technologies such as 4G and 3G, 5G communication pays more attention to characteristics such as high speed and low latency, which puts higher requirements on the performance of antennas.

[0003] Due to the more stringent requirements for signal strength, bandwidth, etc. in 5G communication, more efficient antennas are needed. When designing antennas, it is necessary to consider the gain and efficiency of the antennas to improve the quality of signal reception and transmission. The antennas in 5G communication need to have strong broadband performance and coverage in different directions.

[0004] Moreover, the frequency bands of 5G communication are more subdivided, with more frequency bands and more antennas, and the interference between frequency bands is more serious. Therefore, when designing 5G antennas, it is necessary to ensure the balanced operation of the antennas in different frequency bands to avoid interference.

[0005] There are usually the following two types of such 5G communication antenna products on the existing market:

[0006] (1) 1.5G high-frequency high-gain directional antenna;

[0007] (2) 2.5G full-frequency omnidirectional antenna.

[0008] However, the existing 1.5G high-frequency high-gain directional antenna can only receive signals in a specified direction, and the signal coverage range is small; the antenna gain of the existing 2.5G full-frequency omnidirectional antenna has a small increase, the signal coverage distance is limited, and it is vulnerable to multipath interference and clutter interference. In addition, due to the uniform distribution of the radiation direction of the omnidirectional antenna, some antenna resources will be wasted. Content of the Utility Model

[0009] In view of this, the purpose of the utility model is to design a high-gain 5G smart antenna to replace the traditional single-configured directional antenna and omnidirectional antenna. The antenna with a low frequency band is designed as an omnidirectional antenna to increase the transmission distance, and the high-frequency antenna is designed as a directional antenna to increase the antenna gain, so as to solve the problems of limited coverage of the existing directional antenna and low gain of the omnidirectional antenna; and optimize the isolation performance to avoid interference between antennas in different frequency bands.

[0010] The present utility model provides a high-gain 5G smart antenna, comprising: a 5G module, a plurality of omnidirectional antennas, and a plurality of directional antennas; the plurality of omnidirectional antennas and the plurality of directional antennas are arranged in a row; the structures of the plurality of omnidirectional antennas are completely the same, and the structures of the plurality of directional antennas are completely the same;

[0011] The input end of the omnidirectional antenna is signal-connected to the output end of the 5G module; each directional antenna comprises two groups of directional sub-antennas, wherein one group of directional sub-antennas faces the front of the omnidirectional antenna, and the other group of directional sub-antennas faces the back of the omnidirectional antenna;

[0012] Preferably, the omnidirectional antenna is arranged at a position far from the directional antenna to optimize the isolation performance of the high-gain 5G smart antenna;

[0013] A smart switch is connected between the input ends of the two groups of directional sub-antennas corresponding to each directional antenna and the output end of the 5G module. The number of smart switches is the same as the number of directional antennas. The smart switch performs an alternative switch between the two groups of directional sub-antennas corresponding to each directional antenna. The operation switch between the two groups of directional sub-antennas of each directional antenna is realized through the smart switch.

[0014] Exemplarily, the omnidirectional antenna and the smart switch are always working. After the 5G terminal (5G CPE) is powered on, the 5G module detects and compares the signal intensities of the two groups of directional sub-antennas, and switches through the smart switch to the directional sub-antenna on the side with better signal to work, so that the 5G CPE has both the high gain of the directional antenna and the advantage of wide coverage of the omnidirectional antenna.

[0015] Further, the omnidirectional antenna comprises four groups of omnidirectional antennas, namely ANT0, ANT2, ANT4, and ANT5, and the directional antenna comprises two groups of directional antennas, namely ANT1 and ANT3;

[0016] The four groups of omnidirectional antennas, ANT0, ANT2, ANT4, and ANT5, are low-frequency antennas, and the two groups of directional antennas, ANT1 and ANT3, are high-frequency antennas.

[0017] If a low-frequency antenna is made into a directional antenna, it requires several times the volume of the present utility model. Then, in a limited space, there is not enough space to make a directional antenna. Therefore, in the present utility model, the antenna with low frequency is made into an omnidirectional antenna, and the low-frequency signal has a long transmission distance, which is beneficial to improving the signal transmission distance.

[0018] The transmission distance of high-frequency signals is relatively short. In the present utility model, two groups of high-frequency antennas are made into directional antennas. Directional antennas have high gain, and increasing the gain can improve the transmission distance of high-frequency signals. The existing high-frequency antennas generally have a gain of 3 dBi, while the high-frequency antennas made into directional antennas in the present utility model can achieve a gain of 10 dBi.

[0019] Further, the directional antenna ANT1 includes two groups of directional sub-antennas ANT1-1 and ANT1-2, and the input ends of the directional sub-antennas ANT1-1 and ANT1-2 are connected to one of the intelligent switches;

[0020] The directional antenna ANT3 includes two groups of directional sub-antennas ANT3-1 and ANT3-2, and the input ends of the directional sub-antennas ANT3-1 and ANT3-2 are connected to the other intelligent switch.

[0021] Further, the directional antenna includes: a symmetric dipole PCB antenna and a metal reflector, and the metal reflector is arranged behind the emission direction of the symmetric dipole PCB antenna.

[0022] The metal reflector is placed behind the symmetric dipole PCB antenna, and the beam direction, shape, and signal strength of the symmetric dipole PCB antenna can be adjusted by reflection. By placing the metal reflector behind the symmetric dipole PCB antenna, most of the electromagnetic waves can be reflected back to the original signal radiation direction of the symmetric dipole PCB antenna. The metal reflector has high signal reflection ability, can effectively reflect the radiation energy of the symmetric dipole PCB antenna, thereby improving the beam pointing performance of the directional antenna. The manufacturing process of the metal reflector is simple, the cost is low, and the installation is convenient. It does not require complex debugging and positioning and can be quickly put into use. The symmetric dipole PCB antenna not only has the characteristics of a wide frequency band but also has the advantages of simple structure and light weight. The directional antenna type of the symmetric dipole PCB antenna + metal reflector has excellent directional radiation performance, improves the antenna emission energy, enhances the signal quality; increases the communication distance, expands the communication range; reduces signal leakage, reduces power consumption, and reduces the impact of electromagnetic radiation on the ecological environment.

[0023] Further, the omnidirectional antenna includes: a dipole PCB antenna and a Cable feeder. Among them, the dipole PCB antenna includes: a dipole radiation unit (a symmetric oscillator composed of dipoles), and the dipole radiation unit is electrically connected and mechanically detachably connected to the Cable feeder.

[0024] Further, a shielding layer is arranged outside the Cable feeder. The shielding layer of the Cable feeder shields the interference effect of the feeder on the dipole radiation unit, so that the omnidirectional antenna achieves omnidirectional radiation in the radiation direction.

[0025] Furthermore, the form of the mechanical detachable connection between the dipole radiation unit and the Cable feeder includes any one of screw connection, plug-in connection, snap connection and buckle connection.

[0026] Screw connection can achieve quick screwing installation, plug-in connection can quickly insert and position, and both snap connection and buckle connection can achieve quick snap connection through buckles, making the assembly simple and convenient.

[0027] Furthermore, the shape of the reflecting surface of the metal reflector is any one of a parabolic surface and a super-elliptical surface.

[0028] The shape and size of the metal reflector have an impact on signal reception and transmission. The parabolic surface and the super-elliptical surface have high reflection gain, can make up for the signal loss during transmission, and achieve the purpose of long-distance transmission. Moreover, the parabolic surface and the super-elliptical surface have a wide reflection coverage range, strong anti-interference ability, and stable signal transmission quality.

[0029] Furthermore, a General-Purpose Input / Output (GPIO) interface is provided at the output end of the 5G module, and the intelligent switch is signal-connected to the General-Purpose Input / Output (GPIO) interface, and the switching of the intelligent switch is realized through the GPIO interface.

[0030] Furthermore, the high-gain 5G smart antenna further includes: a WIFI module and a WIFI antenna. The WIFI antenna is electrically connected to the WIFI module, and the WIFI antenna is arranged above the omnidirectional antenna and the directional antenna.

[0031] The WIFI antenna has a wide coverage range and strong wall penetration ability. It is designed at the top position of the high-gain 5G smart antenna to avoid the radiation area of the WIFI antenna being blocked by other antennas (omnidirectional antenna and directional antenna).

[0032] Furthermore, cross-polarized multi-element cascading is adopted between the multiple directional antennas, and the polarization directions of two adjacent directional antennas are cross-polarized.

[0033] Cross-polarization is arranged in an orthogonal polarization manner to achieve the maximum polarization diversity effect. At the same time, it can make the antenna size as small as possible. The area is reduced by half, while the gain is doubled, thus achieving the high gain of the antenna.

[0034] Compared with the prior art, the beneficial effects of the present utility model are:

[0035] The high-gain 5G smart antenna provided by the present utility model has a simple and reasonable structure and strong integrity. The low-frequency antenna is made into an omnidirectional antenna, which improves the transmission distance of low-frequency signals. The high-frequency antenna is made into a directional antenna, which improves the gain and further enhances the transmission distance of high-frequency signals. The isolation performance is optimized to avoid interference between antennas of different frequency bands. By switching to the directional sub-antenna with better signal through the intelligent switch, the 5G terminal antenna not only has the high gain of the directional antenna but also has the wide coverage of the omnidirectional antenna. It can not only better improve the coverage range, but also achieve a high gain in a small-size space, save antenna resources, and improve antenna efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Preferably, the omnidirectional antenna 1 is arranged at a position far from the directional antenna 2 to optimize the isolation performance of the high-gain 5G smart antenna; a smart switch 3 is connected between the input ends of the two sets of directional sub-antennas 4 corresponding to each directional antenna 2 and the output end of the 5G module 5, and the smart switch 3 performs an alternative switch between the two sets of directional sub-antennas 4 corresponding to each directional antenna 2.

The directional antenna ANT1 includes two groups of directional sub-antennas ANT1-1 and ANT1-2, and the input ends of the directional sub-antennas ANT1-1 and ANT1-2 are connected to an intelligent switch; the directional antenna ANT3 includes two groups of directional sub-antennas ANT3-1 and ANT3-2, and the input ends of the directional sub-antennas ANT3-1 and ANT3-2 are connected to another said intelligent switch. In this embodiment, the antenna with low frequency is made into an omnidirectional antenna, and the transmission distance of the low-frequency signal is far, which improves the transmission distance. In the present utility model, the two groups of high-frequency antennas are made into directional antennas. The gain of the directional antenna is high, and increasing the gain can improve the transmission distance. The high-frequency antenna made into a directional antenna in this embodiment can achieve a gain of 10 dBi.

[0049] The directional antenna 2 includes: a symmetric dipole PCB antenna and a metal reflector, and the metal reflector is arranged behind the symmetric dipole PCB antenna in the emission direction.
