[0002] With the development of wireless transmission technology, wireless antenna boxes have been widely used. Existing antenna boxes mostly use a single wireless transmission technology such as 5G or WiFi (wireless network), and are applicable to a single scenario. In order to improve the wireless transmission signal, multiple single-type antennas are set in the box. The multiple antennas interfere with each other, affecting the wireless transmission effect. Therefore, a multifunctional antenna box with less mutual interference is needed to solve the above problems. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a combined antenna box.

[0004] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0005] A combination antenna box includes an antenna box body, the box body including: a shell and an antenna bracket, the shell covering the outer surface of the antenna bracket, the inner cavity of the antenna bracket being provided with a grounding copper foil; a dipole antenna and a MIMO (multiple-in multiple out) antenna are respectively provided at both ends of the first surface of the antenna bracket; a 5G antenna is provided on the side surface of the antenna bracket; the MIMO antenna and the 5G antenna are respectively electrically connected to the grounding copper foil; a connector panel is provided on the second surface of the antenna bracket, the connector panel being provided with a WIFI antenna connector, a MIMO antenna connector and a 5G antenna connector; the WIFI antenna connector is electrically connected to the dipole antenna, the MIMO antenna connector is electrically connected to the MIMO antenna, and the 5G antenna connector is electrically connected to the 5G antenna.

[0006] This demonstrates that by combining the dipole antenna, MIMO antenna, and 5G antenna within the same antenna box, the antenna box can be used in a wider range of scenarios. The MIMO antenna is used to increase the system data rate, reduce the bit error rate, and improve wireless signal transmission quality without increasing system bandwidth or transmit power. The grounding copper foil serves as an extended ground for the MIMO and 5G antennas, enhancing their radiation efficiency.

[0007] According to the above scheme, further, the grounding copper foil includes a MIMO antenna grounding copper foil; the MIMO antenna includes a MIMO antenna substrate, on which a MIMO antenna feeder, a MIMO antenna radiator and a MIMO antenna C-shaped branch are provided; one end of the MIMO antenna feeder is connected to the MIMO antenna radiator, and the other end of the MIMO antenna feeder is connected to the MIMO antenna C-shaped branch; the MIMO antenna C-shaped branch is connected to the MIMO antenna grounding copper foil.

[0008] According to the above scheme, the Dipole antenna includes a Dipole antenna feeder and a Dipole antenna substrate, a ∏-shaped branch is provided on the Dipole antenna substrate, the ∏-shaped branch includes a first side and a second side, one end of the Dipole antenna feeder is connected to the first side of the ∏-shaped branch, and the other end of the Dipole antenna feeder is connected to the second side of the ∏-shaped branch.

[0009] According to the above scheme, the 5G antenna includes a 5G antenna substrate, and the 5G antenna substrate is provided with a 5G antenna feeder, a 5G antenna radiator and a 5G antenna C-shaped branch; one end of the 5G antenna feeder is connected to the 5G antenna radiator, and the other end of the 5G antenna feeder is connected to the 5G antenna C-shaped branch.

[0010] According to the above solution, there are two Dipole antennas, two MIMO antennas and two 5G antennas respectively, and there are two WIFI antenna connectors, two MIMO antenna connectors and two 5G antenna connectors respectively.

[0011] This shows that the dual antenna setup has a better signal.

[0012] According to the above solution, further, the straight lines on which the axes of the two Dipole antennas lie are perpendicular to each other.

[0013] This shows that when two dipole antennas form a 90-degree vertical relationship, one uses vertical polarization and the other uses horizontal polarization, resulting in a polarization mismatch between the two. This makes it difficult for one dipole antenna to receive the signal when the other dipole antenna transmits, thereby achieving the goal of improving the isolation between the two dipole antennas.

[0014] According to the above solution, the two 5G antennas are further arranged on the first side and the second side on both sides of the first surface of the antenna bracket.

[0015] It can be seen that setting them separately on both sides will cause less interference.

[0016] According to the above scheme, further, a 5G antenna grounding copper foil is provided on the bottom surface of the antenna bracket, and a U-shaped choke groove is opened on the surface of the 5G antenna grounding copper foil. The 5G antenna grounding copper foil includes a first 5G antenna connection end and a second 5G antenna connection end, and the first 5G antenna connection end and the second 5G antenna connection end are respectively located on both sides of the U-shaped choke groove; the two 5G antennas are respectively arranged on the first side surface and the second side surface on both sides of the first surface of the antenna bracket, and the first 5G antenna connection end and the second 5G antenna connection end are each connected to one of the 5G antennas.

[0017] According to the above solution, a reserved antenna connector is further provided on the connector panel.

[0018] This shows that when an interface is damaged, it can be replaced in time.

[0019] According to the above solution, further, the shell is a cube with an opening at one end, the joint panel has the same shape as the opening, and the joint panel covers the opening.

[0020] This shows that disassembly is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] One end of the 5G antenna feed line is connected with the 5G antenna radiator 902, and the other end of the 5G antenna feed line is connected with the 5G antenna C-shaped branch 901.

[0036] The first dipole antenna 5 and the second dipole antenna 6 are arranged perpendicular to each other on the end of the upper surface of the antenna bracket 2 away from the opening of the shell 1, and the straight line on the upper surface of the antenna bracket 2 along the direction of the antenna bracket 2 inserted into the shell 1 divides the angle between the first dipole antenna 5 and the second dipole antenna 6 into equal parts.

[0037] The first MIMO antenna 7 and the second MIMO antenna 8 are arranged parallel to a straight line along the upper surface of the antenna bracket 2 and the direction in which the antenna bracket 2 is inserted into the housing 1 , with a certain distance between the first MIMO antenna 7 and the second MIMO antenna 8 .

[0038] Two 5G antennas 9 are arranged on two side surfaces of the antenna bracket 2 that are perpendicular to the plane where the opening of the shell 1 is located.

[0039] The grounding copper foil is arranged on the inner wall of the antenna support 2 .

[0040] The shape of the connector panel 4 is the same as the shape of the opening of the shell 1. The connector panel 2 is connected to the end of the antenna bracket 2 close to the opening of the shell 1. The interface panel is provided with a first 5G antenna connector 3, a reserved antenna connector 10, a first WIFI antenna connector 11, a second WIFI antenna connector 12, a first MIMO antenna connector 13, a second MIMO antenna connector 14 and a second 5G antenna connector 15.

[0045] Because the microstrip antenna surface wave suppression method reduces the influence of the electromagnetic wave propagation of the transmitting antenna on the receiving antenna on the medium surface. The choke groove is a structure that can prevent the transmission of microwave current of a specific frequency, and the structure form is that an air groove with a depth of about 1 / 4 wavelength of the center frequency and a moderate width is opened on the metal surface. When the surface wave current flows through the choke groove, the current is prevented from passing through, thereby improving the isolation between the transmitting antenna and the receiving antenna. The metal choke groove can suppress the surface wave by reasonably designing the size to generate a high-resistance surface effect on the top surface of the groove. Moreover, the choke groove belongs to a planar structure, and has small volume and light weight. Therefore, the choke groove is often used to improve the isolation between antennas. Therefore, the depth of the choke groove is selected to be 1 / 3-1 / 5 wavelength of the center frequency of the Dipole antenna or the MIMO antenna or the 5G antenna, and preferably the depth of the choke groove is 1 / 4 wavelength of the center frequency of the Dipole antenna or the MIMO antenna or the 5G antenna.

Moreover, the antenna box interface of the application is rich in adaptation to various equipment, and a reserved interface is left for convenient and fast maintenance.
