[0047] Referring to Figure 1 , the ultra-wideband antenna of the embodiment of the present utility model includes a support rod 11, a mounting rod 12, a signal processing component 13 and a plurality of protection components 4. Among them, the support rod 11 and the mounting rod 12 are used to support other components and provide support. The mounting rod 12 is vertically connected to the top of the support rod 11, so that other antenna components can be arranged on the mounting rod 12. The signal processing component 13 includes a bandwidth expansion component 2 and multiple groups of radiation units 22, and is used to realize the transmission and processing of Internet of Things signals. The bandwidth expansion component 2 is installed on the mounting rod 12 and is used to increase the available bandwidth of the communication channel, thereby improving the data transmission capacity and efficiency. The bandwidth expansion component 2 includes at least one group of expansion units, and each expansion unit includes two expansion rods 21. According to the actual situation, two groups of bandwidth expansion units can be arranged on both sides of the support rod 11 along the mounting rod 12. Two of the expansion rods 21 are symmetrically connected to both sides of the mounting rod 12, so that the electromagnetic field around the antenna is more uniform and better performance is achieved. The extending direction of each group of expansion units is perpendicular to the extending direction of the mounting rod 12 to realize the expansion of the bandwidth. For ultra-wideband technology, the bandwidth expansion component 2 can make its signal cover a larger frequency band width to realize high-speed data transmission and improve the performance of the ultra-wideband antenna.

[0048] As Figure 1As shown, the radiation unit 22 is mainly used to realize the conversion between electromagnetic waves and electrical signals. It is an important part of the ultra-wideband antenna, used for radiating and receiving electromagnetic waves to improve the signal gain of the ultra-wideband antenna. Each group of radiation units 22 includes two radiation elements 3 connected at the ends. A plurality of radiation elements 3 are symmetrically installed on both sides of the mounting rod 12, and their length directions are perpendicular to the extension direction of the mounting rod 12 and are all located on one side of the bandwidth expansion component 2. According to the actual situation, a connecting structure such as a mounting block can be provided in the middle of each group of radiation units 22 to symmetrically install the radiation elements 3 on the mounting rod 12. The compact and symmetrical arrangement of the radiation elements 3 can effectively improve the gain of the ultra-wideband antenna, reduce interference, and increase the bandwidth to adapt to the use of ultra-wideband technology.

[0049] Referring to Figure 2 、 Figure 3 , the protection component 4 is used to protect the radiation element 3, covering most of the area of the radiation element 3, blocking dust and reducing the contact between rainwater and the radiation element 3. According to the actual situation, the length of the protection component 4 can be the same as that of the radiation element 3 or slightly shorter than the length of the radiation element 3. The number of protection components 4 is the same as the number of radiation elements 3, and a plurality of protection components 4 are respectively sleeved on the outer sides of a plurality of radiation elements 3. Each protection component 4 includes a plurality of connecting members 44 and a plurality of protection units 42. According to the actual situation, the number of connecting members 44 and protection units 42 can be two, three, four or other numbers. A plurality of connecting members 44 and a plurality of protection units 42 are alternately connected to form a series of connections. Among them, the last protection unit 42 in the series connection is connected to the first connecting member 44 in the series connection and forms a closed ring structure. That is to say, the number of protection units 42 is the same as that of connecting members 44. Each connecting member 44 includes a plurality of elastic units arranged along the length direction of the radiation element 3, and both ends of the plurality of elastic units are respectively connected to the protection unit 42. According to the actual situation, the elastic unit can be selected from elastic structures such as springs and telescopic rods. By connecting the protection unit 42 through the connecting member 44, the protection unit 42 can accommodate more sizes of the radiation element 3. Using the elasticity of the connecting member 44, the protection component 4 can adapt to more sizes and different diameters of the radiation element 3, increasing the practicability of the protection component 4.

[0050] When it is necessary to sleeve the protection component 4 on the radiation element 3, such as Figures 2 - 3As shown, the elastic protection component 4 is pulled apart by the elastic structure, increasing the distance between the protection units 42. At this time, the diameter of the annular structure formed by the multiple protection units 42 is greater than the diameter of the radiation element 3, and the operator can sleeved the protection component 4 outside the radiation element 3. After moving the protection component 4 to the appropriate position, release the protection component 4. At this time, the protection units 42 radially contract under the elastic force of the elastic structure, so that the protection units 42 are tightly sleeved outside the radiation element 3, completing the installation of the protection component 4. When it is necessary to disassemble the protection component 4, similarly pull apart the protection component 4 to separate the protection units 42 from the radiation element 3. At this time, the diameter of the annular structure formed by the multiple protection units 42 is greater than the diameter of the radiation element 3, and the operator can remove the protection component 4 from the radiation element 3. The setting of the connecting member 44 and the multiple protection units 42 makes the protection component 4 easy to pick up, facilitating the staff to regularly replace the protection component 4 and greatly reducing the maintenance workload of the staff. Moreover, the protection component 4 covers most parts of the radiation element 3, which can effectively protect the radiation element 3 and extend the service life of the ultra-wideband antenna.

[0051] In some embodiments, referring to Figure 3 , the protection unit 42 is a fan-shaped annular structure, and the annular structure formed by the multiple protection units 42 can better wrap the radiation element 3. According to the number of the protection units 42 and the shape of the radiation element 3, the protection unit 42 can also be composed of other structures, such as a structure with a broken-line cross-section. All the protection units 42 of each protection component 4 are arranged at equal intervals in the circumferential direction, that is, an annular structure is formed.

[0052] Referring to Figure 3 , in some embodiments, the protection unit 42 includes a protection shell 421 and a contact layer 422. The contact layer 422 is used to protect the radiation element 3 and achieve functions such as buffering. The protection shell 421 is arranged outside the contact layer 422 and is used to connect with the elastic structure, so that the protection unit 42 can be fixed on the radiation element 3 by the elastic force provided by the elastic structure. At the same time, the center of the contact layer 422 is coaxially arranged with the center of the protection shell 421. Since the protection units 42 are arranged at equal intervals and the elastic structure is connected to the fixed structure, making the two centers of the contact layer 422 and the protection shell 421 coaxial can ensure that when the protection unit 42 contracts under the elastic force of the elastic structure, the contraction directions of the contact layer 422 and the protection shell 421 are the same, that is, the radial direction.

[0053] Referring to Figure 5, the contact layer 422 includes a shock-absorbing pad 4221, a contact pad 4222, and a plurality of suction cup assemblies 4223. The outer surface of the shock-absorbing pad 4221 is connected to the protective housing 421, and is used to form a buffer between the radiation element 3 and the protective housing 421, so as to avoid the vibration brought by the outside world to the protective housing 421 from being directly transmitted to the radiation element 3 and affecting the radiation element 3. According to the actual situation, the material of the shock-absorbing pad 4221 can be selected from foam materials or other elastic and waterproof organic synthetic materials. The outer surface of the contact pad 4222 is connected to the shock-absorbing pad 4221, and a part of the inner surface is in contact with the radiation element 3, and is used to increase the friction force between the protection unit 42 and the radiation element 3, so as to avoid the protection unit 42 not being well fixed on the radiation element 3 due to sliding, or slipping off the radiation element 3 in case of bad weather outside and not achieving the protection effect well. The inner edge of the contact pad 4222 is wavy, which can achieve the effect of increasing the friction force and increase the contact area between the contact pad 4222 and the radiation element 3. The suction cup assemblies 4223 are used to further fix the protection unit 42 and the radiation element 3, and a plurality of suction cup assemblies 4223 are arranged along the length direction of the contact pad 4222 on the inner side of the contact pad 4222. According to the actual situation, multiple rows of suction cup assemblies 4223 can be set to achieve more stable adsorption. The material of the suction cup assemblies 4223 can be selected from rubber materials or other elastic and waterproof materials. When installing the protection component 4, the protection unit 42 drives the suction cup assemblies 4223 to radially contract, and the suction cup assemblies 4223 continue to be pressed after contacting the radiation element 3 and open outward on the surface of the radiation element 3. At this time, the internal and external pressures of the inner wall of the suction cup assemblies 4223 are different, so that the suction cup assemblies 4223 can adsorb on the outer surface of the radiation element 3, and the protection unit 42 can be fixed on the surface of the radiation element 3.

[0054] Refer to Figure 4, the protection component 4 further includes a movable housing structure 43. The movable housing structure 43 is inclined and disposed outside the protection unit 42 located on the top surface, which is used to block rainwater and dust, and rebound and divert the rainwater to prevent it from staying for a long time and affecting the radiation element 3 and the protection unit 42. The movable housing structure 43 includes a movable housing body 435, a first movable unit 431, and a second movable unit 432. Among them, the movable housing body 435 is inclined and disposed above the protection unit 42. At this time, the distance between one side of the movable housing body 435 and the protection unit 42 is greater than the distance between the other side of the movable housing body 435 and the protection unit 42. That is to say, a certain angle is formed between the movable housing body 435 and the protection unit 42, constituting a slope. For the movable housing bodies 435 disposed on both sides of the mounting rod 12, according to the actual situation, their inclination directions can be the same or opposite. When dust falls, large pieces of dust can roll down along the slope formed by the movable housing body 435 to avoid dust accumulation. When it rains, the raindrops fall along the movable housing body 435 by their own gravity or are directly rebounded. At the same time, the rain falling on the surface of the movable housing body 435 can also carry away the fine dust accumulated on the surface of the movable housing body 435, washing the movable housing body 435 clean, preventing dust and dirt from staying on the movable housing body 435 for a long time, and extending the service life of the ultra-wideband antenna. The movable housing body 435 can prevent most dust and rainwater from falling into the gap of the protection unit 42. For the dust and rainwater falling into the gap of the protection unit 42, since the protection unit 42 is made of waterproof material and only connected by an elastic structure between multiple protection units 42, the rainwater can carry the dust and move along the gap between the protection units 42 in the axial direction of the protection unit 42 and flow out of the protection unit 42 without staying for a long time, avoiding the corrosion of the protection unit 42 and the radiation element 3 by rainwater and dust, and extending the life of the ultra-wideband antenna.

[0055] The first movable unit 431 and the second movable unit 432 provide elastic force for the movement of the movable housing body 435 on the protection unit 42, buffer the impact brought by rainwater, and prevent the radiation element 3 from being affected, such as Figure 4As shown in the figure. Among them, the first movable unit 431 is arranged on the side with a larger distance between the movable housing main body 435 and the protective housing 421. Its two ends are respectively connected to the movable housing main body 435 and the protective housing 421. According to the actual situation, the first movable unit 431 can be a rod-shaped structure made of an elastic material, a spring or other elastic structures. The second movable unit 432 is arranged in the middle of the lower end face of the movable housing main body 435. The two ends of the second movable unit 432 are respectively connected to the movable housing main body 435 and the protective housing 421. When the movable housing main body 435 is subjected to an external impact, since the positions of the first movable unit 431 and the second movable unit 432 are biased towards the side with a larger distance between the movable housing main body 435 and the protective housing 421, therefore, the external impact will cause the movable housing main body 435 to move greatly on the side with a smaller distance from the protective housing 421, and make the movable housing main body 435 more inclined. Rainwater can slide down along the outer surface of the movable housing main body 435 faster, and the rainwater can better wash away the surface dust, avoiding leaving it on the movable housing main body 435, and prolonging the service life of the ultra-wideband antenna.

[0056] In some embodiments, referring to Figure 4 , the second movable unit 432 includes a movable base 4321 and at least one movable rod 4322. According to the actual situation and the structural dimensions, the second movable unit 432 can also be replaced with a structure made of a spring or an elastic material. One end of at least one movable rod 4322 extends into the movable base 4321 arranged outside the protective housing 421 and is movably connected to the movable base 4321. The other end of the movable rod 4322 is connected to the movable housing main body 435 and moves in the movable base 4321 under the influence of the movable housing main body 435. A cavity is formed inside the movable base 4321, and a liquid is injected into the cavity to buffer the movement of the movable rod 4322. According to the actual situation, the bottom of the movable base 4321 may be an open bottom. After being connected to the protective housing 421 of the protection unit 42, it jointly forms a cavity with the surface of the protective housing 421. At this time, the liquid inside the cavity contacts the protective housing 421. In some embodiments, the bottom of the movable base 4321 can also be a closed bottom. At this time, the liquid inside the cavity does not contact the protective housing 421. In some embodiments, the number of movable rods 4322 is two, and the two movable rods 4322 are strip-shaped movable rods 4322 and extend along the length direction of the protection unit 42. Since the vertical cross-sectional shape of the movable base 4321 is matched with the arrangement of the movable rods 4322, when the number of movable rods 4322 is two, the movable base 4321 is a U-shaped movable base 4321. At this time, the two movable rods 4322 are movably connected by extending from both sides of the movable base 4321 respectively.

[0057] Referring to Figure 6, the vertical cross-section of the movable rod 4322 is an inverted T shape, including a support rod 4323 and an elastic part 4324. The elastic part 4324 is arranged at the bottom end of the support rod 4323 and has elasticity. According to the actual situation, an elastic washer or a rubber sealing ring can be selected as the elastic part 4324, and the movable rod 4322 extends into the movable base 4321 through the elastic part 4324. When installing the second movable unit 432, first install the movable base 4321 to form a cavity together with the surface of the protective housing 421. Then, inject liquid into the cavity through the opening at the top end of the movable base 4321 for movably connecting with the movable rod 4322. According to the actual situation, water or oil can be selected as the injected liquid. After the liquid injection is completed, install two movable rods 4322 through the openings on the protrusions on both sides of the U-shaped structure of the movable base. To prevent the movable rod 4322 from sliding out of the movable base 4321, the size of the elastic part 4324 is larger than the opening at the top end of the movable base 4321. Therefore, the movable rod 4322 needs to be deformed through the elastic part 4324 so that it can extend into the movable base 4321. After the elastic part 4324 enters the movable base 4321, due to its own elastic recovery of shape, the movable rod 4322 will not slip out of the movable base 4321. At the same time, since the size of the elastic part 4324 is larger than the opening at the top end of the support part and its material is an elastic washer or a rubber sealing ring, which has a certain sealing effect, it can also prevent the liquid inside the cavity from overflowing when the protection component 4 moves.

[0058] The movable housing main body 435 is connected to the protection unit 42 through the first movable unit 431 and the second movable unit 432, as Figure 4 shown. When rain falls on the movable housing main body 435, the movable housing main body 435 is affected by the impact force of the rain, driving the two movable rods 4322 to move in the movable base 4321. The liquid in the movable base 4321 buffers the movement of the two movable rods 4322 to prevent damage to the movable housing structure 43. When the rainfall stops and the movable housing main body 435 is no longer affected by the rain impact, the liquid level in the cavity returns to a stable state. At the same time, the two movable rods 4322 return to their original positions to realize the reset of the movable housing structure 43.

[0059] Refer to Figure 1, in some embodiments, the ultra-wideband antenna further includes an oscillator 5, a reflection component 7, and a lightning rod 6. The oscillator 5 is used to direct and amplify electromagnetic wave signals, enabling the ultra-wideband antenna to transmit and receive stronger electromagnetic signals. The oscillator 5 is a loop oscillator and is installed on the mounting rod 12 through the mounting structure in the middle thereof. The mounting rod 12 passes through the middle of the oscillator 5 from the mounting structure, dividing the oscillator 5 into two parts that are symmetric about the mounting rod 12 left and right. The oscillator 5 is arranged on the same side of the support rod 11 as the plurality of radiation elements 3 and is located between two groups of bandwidth expansion units. The oscillator 5 can enhance the signals coming from the space and direct them to the radiation elements 3. At the same time, the signals emitted by the radiation elements 3 can also be enhanced and amplified through the oscillator 5 to obtain a better transmission effect.

[0060] The reflection component 7 is arranged between the radiation element 3 and the oscillator 5 and bends towards the oscillator 5 side, as Figure 1 shown. The reflection component 7 includes a main body rod 71 and a plurality of reflection rods 72. The plurality of reflection rods 72 are symmetrically distributed on both sides of the main body rod 71, and the extending directions of the plurality of reflection rods 72 are parallel to the extending direction of the radiation element 3. According to the actual situation, the main body rod 71 may be an arc rod or may adopt a broken-line rod-shaped structure. The mounting rod 12 passes through the middle of the main body rod 71, dividing the reflection component 7 into two parts that are symmetric about the mounting rod 12 up and down. The reflection component 7 can reflect the signals processed by the oscillator 5, enhance the signal intensity and radiation intensity, and improve the information transmission quality.
