Description

Technical Field

[0001] This invention relates generally to the field of wireless communication, and more specifically to a base station antenna, particularly a small base station, and an endplate assembly for the base station antenna and a method for manufacturing the same. Background Technology

[0002] Mobile communication networks comprise numerous base stations, each of which may include one or more base station antennas for receiving and transmitting radio frequency signals. A single base station antenna may include many radiating components, also known as antenna elements or radiating elements. Mobile phone operators currently require base station antennas operating in two, three, or more frequency bands, while maintaining strict limitations on the size of these antennas. Therefore, base station antenna design presents an increasing challenge, requiring operators to meet both functional and size requirements.

[0003] Small cells, or small cell antennas, are typically cylindrical in shape to provide omnidirectional coverage in the azimuth plane. These small cells usually have a cylindrical radome with an open bottom end, and the small cell, or antenna, or other parts of the antenna assembly are mounted on a metal endplate. The radome covers the antenna assembly, and the metal endplate closes the open bottom end of the radome. Mounting brackets can be attached to the outer surface of the endplate and can be used to secure the small cell to a foundation such as a utility pole, antenna tower, building, or the like. Because the endplate structurally supports the antenna assembly, it is made of metal to provide a high level of strength and rigidity. However, especially in the 5G era, antenna elements can be very sensitive. Large metal endplates can negatively impact the performance of base station antennas, for example, in terms of passive intermodulation (PIM), return loss, and insulation performance.

[0004] PCT application WO2017 / 165512A1 describes a base station antenna including an end cap made of glass fiber reinforced plastic that connects to an radome. In this case, the base station antenna is mounted on a base via its radome, and the end cap does not provide structural support. Furthermore, the molded end cap has a through-hole arrangement for electrical connectors (e.g., RF ports) predetermined during molding, making it uneconomical as such an end cap is only suitable for a specific type of base station antenna. Summary of the Invention

[0005] The purpose of this invention is to provide an endplate assembly for a base station antenna, a method for manufacturing the same, and a base station antenna including such an endplate assembly, wherein the endplate assembly can be flexibly used in different base station antennas and can achieve improvements in base station antenna performance, particularly in passive intermodulation, return loss, and insulation performance.

[0059] Figures 6A to 6C They are respectively by Figure 1 Enlarged view of multiple individual components of a base station antenna;

[0060] Figure 7A and 7B This is a schematic top view of an endplate assembly according to another embodiment;

[0061] Figure 8 This is a schematic diagram of the arrangement of radiating elements on a reflector. Detailed Implementation

[0062] Figure 1 This is a schematic diagram of a base station antenna 100 according to one embodiment. The base station antenna 100 can be a small base station or a small base station antenna. The base station antenna includes an radome 101 having an end opening at the bottom. The radome 101 can be constructed in a cylindrical, cuboid, or other shape. The base station antenna can have a weight of several kilograms to tens of kilograms, preferably less than 10 kg.

[0063] The base station antenna 100 includes an end plate assembly 102 that closes an end opening at the bottom of the radome 101. The end plate can be fixed in the end opening at the bottom of the radome 101. The base station antenna 100 can be mounted on a foundation, such as a utility pole, using mounting brackets. The longitudinal axis of the base station antenna 100 can be oriented in the direction of gravity or at an angle to the direction of gravity. The base station antenna 100 can be cantilevered on the foundation using mounting brackets. The base station antenna 100 can also be additionally supported at other locations. The antenna assembly mounted within the radome 101 can include various components, such as reflectors, radiating elements, electronic components, cables, etc.

[0064] Figure 2 Is according to Figure 1 A partial perspective view of the base station antenna 100, and Figure 3 and Figure 4 Is according to Figure 1A partial perspective view of the end plate assembly 102 of the base station antenna 100. Figure 5A and 5B These are top and bottom perspective views of the end plate 1 of the end plate assembly 102.

[0065] like Figure 5A and Figure 5B As shown, the end plate 1 has an outer first side 11 (lower side) and an inner second side 12 (upper side) opposite to the first side. The end plate 1 includes a bottom 14 and a peripheral wall 15, in which a plurality of notches 16 are provided. When the end plate 1 closes the end opening at the bottom of the radome 101, a seal can be formed between the outer peripheral surface of the peripheral wall 15 and the inner peripheral surface of the radome 101. The profile shape of the end plate 1 corresponds to the shape of the inner peripheral surface of the radome 101. For example, the end plate 1 may have a circular profile, a rectangular profile, or a regular hexagonal profile.

[0066] End plate 1 can be a molded part made of a dielectric material, such as glass fiber reinforced plastic. End plate 1 can be formed by molding an end plate blank in a mold and then machining the end plate blank into end plate 1. Machining can include, but is not limited to, punching, drilling, cutting and other machining methods.

[0067] The end plate 1 may have multiple machined first through holes 13. The mounting bracket 2 is fixed to the first side 11 (lower side) of the end plate 1 by a first connecting element 4. Here, the mounting bracket 2 has three legs, each leg having a through hole for receiving the corresponding first connecting element 4. Correspondingly, the number of first through holes 13 in the end plate 1 is three. The through holes in the legs of the mounting bracket 2 can also be replaced by blind holes, but this design may impose strict requirements on the length of the first connecting element 4. If each leg of the mounting bracket 2 has two through holes for receiving the first connecting element 4, the number of first through holes 13 in the end plate 1 can be increased to six. Other numbers of first through holes 13 are possible. In some embodiments, the through holes in each leg of the mounting bracket 2 may have internal threads, thus eliminating the need for a separate nut for screwing onto the external threads of the first connecting element 4. The mounting bracket 2 may be made of metal, such as aluminum or aluminum alloy; or it may be made of plastic, such as glass fiber reinforced plastic.

[0068] In this application, all connecting elements may be screws, rivets, expansion plugs, or other connecting elements.

[0069] As in Figure 3 and Figure 4As shown, a plurality of first fittings 3 are provided, which may be made of metal such as aluminum or aluminum alloy. Alternatively, the first fittings 3 may be made of plastic, such as glass fiber reinforced plastic. Here, each first fitting 3 is configured as an L-shape, having a planar section 21 and a connecting section 22. The planar section 21 rests planarly against the second side surface 12 (upper side) of the end plate 1 and has a through hole, while the connecting section 22 is disposed in a notch 16 of the end plate 1. A first connecting element 4 passes through the through hole of the planar section 21 of the first fitting 3, the first through hole 13 of the end plate 1, and the through hole in the leg of the mounting bracket 2, in order to fix the mounting bracket 2 to the first side surface 11 of the end plate 1. Figure 3 and Figure 4 As shown, a pin hole 5 may be provided next to the through hole of each planar section 21. A locating pin is inserted into each pin hole 5 and can be pressed into or extended into a recess in the second side surface 12 of the end plate 1 to further prevent the first fitting 3 from rotating around the corresponding first connecting element 4. The recess may be machined or may be pressed out by the locating pin when it is installed into the corresponding pin hole 5. Each connecting section 22 may have at least one through hole with internal threads for receiving a screw screwed into the through hole from the outer peripheral surface of the radome 101 to secure the end plate assembly 102 to the end opening of the radome 101. The through hole with internal threads in the connecting section 22 may be provided, for example, by a press-fit nut pressed into the through hole of the connecting section 22, as in an exemplary embodiment, such as in Figure 4 As shown, two press-fit nuts may be provided in each connection section 22.

[0070] Here, the first accessory 3 not only functions to connect the radome 101 to the end plate assembly 102, but also functions to work in conjunction with the first connecting element 4. However, it is also possible that, as an alternative, these two functions can be achieved by two separate components. For example, the connecting section 22 can be an integral part of the end plate 1, and the planar section 21 can be a separate component.

[0071] exist Figure 6A The partial perspective view further illustrates the connection structure between one leg of the mounting bracket 2 and one of the first fittings 3 via a first connecting element 4 and a locating pin. Figure 6A The end plate area sandwiched between the planar section 21 and the legs of the mounting bracket 2 is omitted to more clearly illustrate the positioning pin inserted into the pin hole 5. Here, the planar section 21 can distribute the force of the first connecting element 4 to the end plate 1, and the planar section 21 can reinforce the end plate 1. Therefore, the end plate assembly 102 can not only support the entire base station antenna 100, but also achieve better performance compared to the case of a metal end plate, especially in terms of passive intermodulation, return loss, and insulation performance.

[0072] The end plate 1 may have multiple machined second through holes 17 and multiple machined third through holes 18 around each of the second through holes 17. An electrical connector 6 is accommodated in each of the second through holes 17. A second connecting element 7 for securing the electrical connector 6 to the end plate 1 is accommodated in each of the third through holes 18. The size, number, and layout of the second through holes 17 and the third through holes 18 can be flexibly achieved through machining in the end plate blank according to actual needs.

[0073] exist Figure 6C The partial detailed drawing illustrates the mounting of a single electrical connector 6 on an end plate 1 in some embodiments. This electrical connector 6 may be, for example, a 4.3-10 connector. In addition to the 4.3-10 connector, an AISG connector may also be mounted on the end plate 1. The electrical connector 6 may include a body and a flange 23, the body being received in a second through-hole 17 in the end plate 1. The flange 23 has a threaded through-hole at each of its four corners, these through-holes in the flange 23 being aligned with corresponding third through-holes 18 around the second through-hole 17. A second connecting element, for example configured as a screw, is received in each through-hole of the flange 23 and in the third through-hole 18 below it.

[0074] This connection structure is particularly advantageous. Each connection point can have only one unique metal-to-metal contact, namely the metal-to-metal contact between the second metal connecting element 7 and the metal flange 23. Fewer metal-to-metal contacts generally mean better performance. Furthermore, when the base station antenna requires maintenance, repair, or rework, the individual first connecting elements can be loosened first, and then the end plate 1 can be removed from the base station antenna 100 without disassembling the electrical connector 6 and associated cables.

[0075] The end plate 1 may have a plurality of machined fourth through holes 19, each of which accommodates a third connecting element 8 for fixing the reflector 103 to the second side 12 (upper side) of the end plate 1. In some embodiments, such as in Figure 3 As schematically depicted, the base station antenna 100 may have exactly one reflector 103. For this reflector 103, a plurality of fourth through holes 19 are provided in the end plate 1. Additionally, a plurality of second fittings 9 are provided. These second fittings 9 may be metal components, such as stamped aluminum or cast aluminum components; or they may be plastic components, such as those made of glass fiber reinforced plastic.

[0076] Here, the second fitting 9 can be configured in an L-shape, having a planar section 24 and a connecting section 25. The planar section 24 rests planarly against the second side surface 12 of the end plate 1 and can have one or more through holes with internal threads (which can be achieved, for example, by press-fit nuts pressed into each through hole). The third connecting element 8 passes through each of the fourth through holes 19 in the end plate 1 and the through holes of the planar section 24 to secure each second fitting 9 to the second side surface 12 of the end plate 1. The connecting section 25 of each second fitting 9 can be connected to the reflector 103 via the connecting element.

[0077] exist Figure 6B The image depicts a perspective view of one of the second fittings 9 together with the third connecting element 8. Two third connecting elements 8 configured as screws and two press-fit nuts disposed in the planar section 24 are visible. The number of connection points is exemplary; it goes without saying that more connection points may be provided as needed.

[0078] Figure 7A and 7B This is a schematic top view of the endplate assembly 102 according to another embodiment. Figure 7A The antenna assembly includes four reflectors 103, and therefore four second fittings 9, each mating with one of the reflectors 103. Radiation elements of the same or different frequency bands can be disposed on each reflector 103. Figure 7B There are a total of eight second accessories 9, each of which is matched with a corresponding reflector 103 of the base station antenna 100. Therefore, Figure 7B The base station antenna has a total of eight reflectors 103. Radiation elements of the same or different frequency bands can be set on each reflector. In other aspects of the base station antenna 100, [the following is not specified]. Figure 7A and Figure 7B The following is a detailed description, and you can refer to the previous implementation methods for details.

[0079] In some undescribed embodiments, instead of the second fitting 9, the reflector 103 may have a curved end region or an L-shaped end region that rests planarly against the second side surface 12 of the end plate 1 and is fixed to the second side surface 12 by means of a third connecting element 8.

[0080] Figure 8 This is an exemplary schematic diagram of the arrangement of radiating elements 104 on reflector 103. An array of identical or different radiating elements 104, or oscillators, can be provided on reflector 103. As a supplement, an array of parasitic elements 105 for adjusting the performance of base station antennas can also be provided.

[0081] The endplate assembly 102 according to the present invention is interchangeable with existing metal endplates, that is, other components of the base station antenna can remain unchanged, or only require slight adaptive changes to other components of the base station antenna.

[0082] Finally, it should be noted that the above embodiments are merely for understanding the present invention and do not constitute a limitation on the scope of protection of the present invention. Those skilled in the art can make modifications based on the above embodiments, and these modifications do not depart from the scope of protection of the present invention.
