Description

Technical Field

[0001] This utility model relates to antenna technology, and more particularly to a high-power omnidirectional antenna and communication equipment. Background Technology

[0002] Antennas are an indispensable basic component in wireless communication systems. They can convert electrical signals and electromagnetic wave signals to each other, enabling the reception and transmission of wireless signals. However, antennas have a limited operating bandwidth, meaning they can only provide good transmission and reception performance within a specific frequency range. Different frequency band antennas require a duplexer to combine their operating frequency bands, which can lead to communication blind spots when providing full-band coverage. To achieve a wider operating bandwidth, antennas need to be larger and heavier, and current antenna power capacity is insufficient. Utility Model Content

The connector assembly is connected to the power supply point between the first radiating component and the second radiating component to power the first radiating component and the second radiating component.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0017] Figure 1 and Figure 2 A schematic diagram of a high-power omnidirectional antenna provided for an embodiment of this utility model is shown below. Figure 1 and Figure 2 As shown, the high-power omnidirectional antenna provided in this embodiment includes: a first radiating component 11 and a second radiating component 12 located on a straight line. The first radiating component 11 and the second radiating component 12 have the same size, and the first radiating component 11 and the second radiating component 12 serve as two radiators of a dipole antenna.

[0018] The first radiating component 11 and the second radiating component 12 are surrounded by an insulating housing component 13. The lower end of the first radiating component 11 includes a connector component 14 as a power supply port. The connector component 14 is connected to a power supply point 15 between the first radiating component 11 and the second radiating component 12 to supply power to the first radiating component 11 and the second radiating component 12. The first radiating component 11 and the second radiating component 12 are surrounded by a sleeve component 16 that is coaxial with the first radiating component 11 and the second radiating component 12. The sleeve component 16 is made of metal and its diameter is larger than the diameter of the housing component 13 outside the first radiating component 11.

[0019] The first radiating element 11 and the second radiating element 12 form a basic dipole antenna structure. The first radiating element 11 and the second radiating element 12 serve as the two dipole radiators of the dipole antenna. The first radiating element 11 and the second radiating element 12 are of the same size and are located on the same straight line. Since the first radiating element 11 and the second radiating element 12 are made of metal, they are encased in an insulating outer shell assembly 13. The outer shell assembly 13 prevents the first radiating element 11 and the second radiating element 12 from being affected by external interference, thus protecting the overall radiation performance of the antenna. The lengths of the first radiating element 11 and the second radiating element 12 are designed based on a quarter-wavelength corresponding to the basic operating frequency band of a high-power omnidirectional antenna. The dipole antenna is a type of omnidirectional antenna.

[0020] A connector assembly 14 is provided at the lower end of the first radiating element 11. The connector assembly 14 serves as the feed port for the entire high-power omnidirectional antenna, handling both radio frequency (RF) signal input and output. The connector assembly 14 can be any type of connector, determined by the type of output port connector required by the RF component to be connected to the high-power omnidirectional antenna. Generally, the connector assembly 14 is a coaxial connector, meaning the high-power omnidirectional antenna is connected to the RF component via a coaxial cable. The feed point 15, connected to the connector assembly 14 between the first radiating element 11 and the second radiating element 12, supplies power to both components.

[0021] The first radiating element 11 and the second radiating element 12 are surrounded by a sleeve assembly 16 coaxial with the first radiating element 11 and the second radiating element 12. The sleeve assembly 16 is made of metal and its diameter is larger than the diameter of the outer shell assembly 13 outside the first radiating element 11. That is, a coaxial metal sleeve assembly with a larger diameter is fitted outside the first radiating element 11 and the second radiating element 12. Setting the sleeve assembly 16 outside the basic dipole antenna composed of the first radiating element 11 and the second radiating element 12 can effectively extend the antenna's operating frequency band. For example, the effective operating frequency band of the antenna can be extended to five times the basic frequency band.

[0022] The high-power omnidirectional antenna provided in this embodiment includes a first radiating component and a second radiating component located on a straight line, and a sleeve assembly located outside the first radiating component and the second radiating component and coaxial with it. The first radiating component and the second radiating component include an insulating outer shell assembly. The first radiating component and the second radiating component are connected to a feed point between the first radiating component and the second radiating component through a connector assembly for feeding, thus providing a sleeve dipole antenna and extending the effective bandwidth of the antenna.

[0023] Furthermore, in Figure 1 and Figure 2 Based on the high-power omnidirectional antenna of the embodiment shown, a choke component 17 can also be provided between the first radiating component 11 and the connector component 14. The choke component 17 can suppress the common-mode current transmitted to the antenna through the feed line via the connector component 14, thereby improving the radiation performance of the antenna.

[0024] exist Figure 1 and Figure 2 Based on the high-power omnidirectional antenna of the embodiment shown, the length of the sleeve assembly 16 can be the same as the length of the first radiating assembly 11 and the second radiating assembly 12, and the sleeve assembly 16 is symmetrically arranged at the center of the first radiating assembly 11 and the second radiating assembly 12. That is, the center of the sleeve assembly 16 is located at the center of symmetry of the first radiating assembly 11 and the second radiating assembly 12.

[0025] The sleeve assembly 16 is made of perforated metal. Since the sleeve assembly 16 is arranged around the first radiating assembly 11 and the second radiating assembly 12 and has a large diameter, the wind resistance is large. In order to reduce the wind resistance of the entire high-power omnidirectional antenna and avoid affecting the working performance of the antenna, the sleeve assembly 16 can be made of perforated metal. On the one hand, it can reduce wind resistance, and on the other hand, it can reduce the weight of the entire antenna.

[0026] Furthermore, Figure 3 This is a schematic diagram of the sleeve assembly structure of a high-power omnidirectional antenna provided in an embodiment of this application, as shown below. Figure 3 As shown, the sleeve assembly 16 can be connected to the outer shell assembly 13 outside the first radiating assembly 11 and the second radiating assembly 12 via the sleeve bracket 18. The sleeve bracket 18 is made of fiberglass. Fiberglass, as an insulating material, has advantages such as corrosion resistance, impact resistance, good wave transmission characteristics, and light weight. The sleeve assembly 16 can be made of multi-strand steel wire mesh made of 316 steel, thereby greatly reducing wind resistance on the horizontal plane of the antenna and improving antenna stability. The sleeve bracket 18 can be bolted to the outer shell assembly 13, and the sleeve assembly 16 is fixed to the sleeve bracket 18 with fixing screws.

[0027] Furthermore, Figure 1 and Figure 2 In the embodiment shown, the outer shell assembly 13 can be made of glass fiber. In order to improve the power capacity of the antenna, the current fed into the first radiator 11 and the second radiator 12 will be larger, and the first radiator 11 and the second radiator 12 will generate more heat. Therefore, glass fiber is used as the material of the outer shell assembly 13. Since the heat resistance temperature of the glass fiber tube is between 300℃ and 500℃, it can meet the temperature requirements of the antenna when it is working at high power.

[0028] Figure 4 A schematic diagram of another high-power omnidirectional antenna provided in this embodiment of the present invention is shown below. Figure 4 As shown, the high-power omnidirectional antenna provided in this embodiment... Figure 1 and Figure 2 Based on the high-power omnidirectional antenna shown, a matching component 21 is further included between the first radiating element 11 and the second radiating element 12. The matching component 21 is used to perform impedance matching on the dipole antenna composed of the first radiator 11 and the second radiator 12, and to act as a balun to unbalanced converter to improve the antenna's radiation performance. Figure 4 The power supply point 15 is not shown in the diagram. The power supply point 15 is located between the mating assembly 21 and the connector assembly 14.

[0029] Figure 5 This is a schematic diagram of the matching component structure of a high-power omnidirectional antenna provided in an embodiment of this application, as shown below. Figure 4As shown, the matching component 21 includes a dielectric substrate 22 and a copper sheet 23 on the dielectric substrate 22. The copper sheet 23 is connected to the dielectric substrate 22 by a hollow copper rivet 24. An inductor component (not shown in the figure) is welded in the hollow copper rivet 24. The power supply point 15 is located on the dielectric substrate 22.

[0030] Figure 5 The matching assembly shown includes multiple copper sheets 23 of different shapes, which can be disposed on both sides of the dielectric substrate 22. Each copper sheet 23 has multiple circular holes, and hollow copper rivets 24 are fixed to the dielectric substrate 22 through these holes. Inductors are welded into the hollow copper rivets 24, and these inductors serve as antenna matching elements to perform impedance matching between the first radiating assembly 11 and the second radiating assembly 12. Figure 5 As can be seen, the copper sheet 23 on the dielectric substrate 22 is relatively large. This is because copper has a high thermal conductivity and low electromagnetic signal transmission loss. Since the matching component 21 cannot achieve perfect matching, some signal reflection will generate heat. Therefore, using a copper sheet as part of the matching component 21 can meet the temperature requirements of the antenna during high-power operation. The dielectric substrate 22 can be made of polytetrafluoroethylene (PTFE), which has low loss and high temperature resistance, with a heat resistance temperature above 500℃. It can work with the copper sheet 23 to achieve impedance matching for the antenna.

[0031] The inductor component can be fixed in the copper rivet 24 by current welding. Current welding uses the principle of induction heating generated by high frequency current to heat the metal material to the melting point and realize the welding of the metal material. The melting point of copper is above 800℃, so the welding point meets the temperature requirements of the antenna when it is operating at high power.

[0032] Figures 6 to 8 This is a temperature simulation diagram of a high-power omnidirectional antenna provided in an embodiment of the present invention. Assuming the maximum VSWR of the high-power omnidirectional antenna shown in this embodiment is 2.5, and the maximum reflected signal power is 50W when the antenna operates at a maximum power of 400W, and all of it is converted into heat, the temperature simulation diagram under external thermal equilibrium of the antenna is shown below. Figure 6 As shown in the figure, the temperature simulation diagram during internal thermal equilibrium of the antenna is as follows: Figure 7 As shown, the heat flow diagram at antenna thermal equilibrium is as follows: Figure 8 As shown.

[0033] from Figures 6 to 8As can be seen, when the antenna is in thermal equilibrium, the temperature of the antenna's outer shell assembly is around 145℃, while the temperature of the internal matching assembly is below 200℃. The heat resistance temperature of the fiberglass tube is 300~500℃, therefore, the antenna's outer shell assembly meets the temperature requirements for high-power antenna operation. The internal matching assembly is made of copper and polytetrafluoroethylene, with a heat resistance temperature above 500℃, thus meeting the requirements. The inductor component is fixed to the matching assembly by current welding. Current welding utilizes the induction heating principle generated by high-frequency current to heat the metal material to its melting point, achieving the welding of the metal materials. Copper's melting point is above 800℃, therefore, the weld joint meets the temperature requirements for high-power antenna operation.

[0034] This utility model embodiment also provides a communication device, including a high-power omnidirectional antenna and a radio frequency transceiver component as shown in any of the above embodiments. The high-power omnidirectional antenna is connected to the radio frequency transceiver component through a feed port. The communication device provided by this utility model embodiment can be applied to scenarios requiring high-power broadband transmission.
