[0002] With the rapid development of technology in the field of mobile communications, communication base stations have higher and higher requirements for antennas. In addition, the current situation of multi-standard operation of mobile communications and the difficulty in site selection of base stations has made multi-frequency electrically steered antennas the first choice for base stations. Especially in the 5G network era, one antenna is required to integrate all 4G network standard antennas, and multiple antenna arrays are set in the antenna. At the same time, the tower company requires the antenna to have a smaller windward area and lighter weight. Therefore, the miniaturization design of the antenna cross section has become a development trend. The cross-section miniaturization design makes the array layout compact between multiple frequency bands, especially the multi-frequency and multi-port antennas with high and low frequency arrays. Different array networks are stacked high and low, and the feed phase shifting network uses coaxial cable phase matching to achieve phase balance. Traditional antenna units usually include components such as radiating arms, baluns, reflectors and phase shifters. The components are generally welded to each other or assembled by screws. However, the transportation and assembly of each component can easily cause damage to the feed phase shifting network, and the wiring link of the whole machine assembly is complicated, which can easily cause assembly errors and low assembly efficiency, which brings great challenges to the mass production and promotion of multi-frequency and multi-port antennas that meet the needs of co-site sharing.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0030] See also Figures 1 to 3 , Figure 1 FIG. 4 is a schematic diagram showing the structure of an integrated antenna unit according to an embodiment of the present invention. Figure 2 A schematic diagram of the structure of an antenna device according to an embodiment of the present invention from one viewing angle is shown. Figure 3 Shows Figure 2 Another perspective structural schematic diagram of the antenna device shown. An embodiment of the present invention provides an integrated antenna unit, the integrated antenna unit comprising: a radiation unit 10 and a reflector 20. The radiation unit 10 comprises at least two baluns 11 and at least two radiation arms 12. The baluns 11 and the radiation arms 12 are arranged one by one, and the baluns 11 are connected to the corresponding radiation arms 12. The reflector 20 is respectively connected to all the baluns 11, and the reflector 20 and the radiation unit 10 are stamped integrally.
[0031] The above-mentioned integrated antenna unit, since the reflector 20 and the radiation unit 10 are integrally stamped and formed, that is, the reflector 20, the balun 11 and the radiation arm 12 are integrally stamped and formed, thereby realizing the integration of electromagnetic wave radiation and reflection, can simplify the structural composition of the integrated antenna unit, while reducing the complexity of the whole machine assembly process, making it easy to realize production automation, reducing production hours and improving the consistency and reliability of antenna assembly, greatly improving production efficiency and reducing production costs. In addition, the material composition of the antenna device can be minimized, and only the reflector 20 and the phase shifter 40 need to be assembled together to form an antenna device. The antenna device is simple and compact, maximizing the savings in material costs and assembly labor costs, and the antenna device is light in weight.
[0032] Please refer to Figure 1 In one embodiment, a stamping notch 21 is provided on the reflector 20, and the shape of the radiation unit 10 after flattening is adapted to the stamping notch 21. In this way, during manufacturing, the stamping notch 21 is formed on the reflector 20 by a stamping machine, and the material at the stamping notch 21 is punched out to form the radiation unit 10. In addition, in this embodiment, the reflector 20 is a metal plate. After the reflector 20 is stamped to form the radiation unit 10, the balun 11 and the radiation arm 12 are made of the same material as the reflector 20, which is also a metal plate.
[0033] Please refer to Figure 1 In one embodiment, the balun 11 and the radiating arm 12 of the radiating unit 10 are both four. The center line of one pair of diagonally arranged two radiating arms 12 is orthogonal to the center line of the other pair of diagonally arranged two radiating arms 12. In this way, one pair of diagonally arranged two radiating arms 12 is equivalent to forming a dipole, which is responsible for radiating and receiving electromagnetic signals in one polarization direction (for example, +45°); the other pair of diagonally arranged two radiating arms 12 is equivalent to forming a dipole, which is responsible for radiating and receiving electromagnetic signals in another polarization direction (for example, -45°), that is, the function of a dual-polarized antenna is realized.
[0034] See also Figures 4 to 6 , Figure 4 Shows Figure 2 The schematic diagram of the exploded structure of one of the radiation units 10 of the antenna device shown in FIG. Figure 5 Shows Figure 4 A schematic diagram of the enlarged structure at A. Figure 6 Shows Figure 4The schematic diagram of the exploded structure of the insulating fixing member 50 and the two feeding members 30 shown in the figure. In one embodiment, the integrated antenna unit also includes two feeding members 30 arranged corresponding to the radiation unit 10. One of the feeding members 30 is respectively connected to one pair of diagonally arranged two radiating arms 12 for feeding, and the other feeding member 30 is respectively connected to another pair of diagonally arranged two radiating arms 12 for feeding. The feeding member 30 is used to be connected to the network signal transmission end (not shown in the figure) of the phase shifter 40. In this way, one of the feeding members 30 can realize the transmission of the feeding signal of the phase shifter 40 to one pair of diagonally arranged two radiating arms 12, and can also realize the transmission of the received antenna signal to the phase shifter 40; similarly, the other feeding member 30 can realize the transmission of the feeding signal of the phase shifter 40 to another pair of diagonally arranged two radiating arms 12, and can also realize the transmission of the received antenna signal to the phase shifter 40.
[0035] See also Figures 4 to 6 In one embodiment, the integrated antenna unit further includes an insulating fixture 50 disposed corresponding to the radiation unit 10. The insulating fixture 50 is disposed on the radiation arm 12, and the two feeders 30 are disposed on the insulating fixture 50, so that the feeders 30 are coupled and fed with the radiation arm 12. In this way, the two feeders 30 are stably mounted on the radiation unit 10 through the insulating fixture 50, and the insulating fixture 50 can prevent the feeders 30 from directly contacting the radiation arm 12 and affecting the intermodulation index, and one of the feeders 30 is spaced apart from one pair of diagonally arranged two radiation arms 12, respectively, to achieve coupled feeding connection, and another feeder 30 is spaced apart from another pair of diagonally arranged two radiation arms 12, respectively, to achieve coupled feeding connection.
[0036] As an optional solution, it is not limited to the implementation method of setting the insulating fixing member 50, that is, the insulating fixing member 50 is omitted, and solder is set on the feeder 30 and the radiation arm 12, and the feeder 30 and the radiation arm 12 are directly fed and connected by welding.
[0037] See also Figures 4 to 6 In one embodiment, each feeder 30 includes a transverse section 31 and two vertical sections 32 connected to both ends of the transverse section 31. The two transverse sections 31 are arranged alternately up and down and are arranged above the radiation unit 10 at intervals. Specifically, the insulating fixing member 50 includes four insulating sleeves 51, and the four insulating sleeves 51 are respectively and correspondingly arranged through the four radiation arms 12, and the four vertical sections 32 are respectively and correspondingly inserted into the inside of the four insulating sleeves 51. In this way, the vertical section 32 of the feeder 30 can avoid contact with the radiation arm 12 under the isolation effect of the insulating sleeve 51, thereby realizing the corresponding coupling feeding of the two vertical sections 32 of each feeder 30 to the two radiation arms 12 arranged diagonally.
[0038] It should be noted that the two transverse sections 31 are arranged in an up-and-down staggered manner, which means that one transverse section 31 is arranged above the other transverse section 31 at intervals, and the projections of the two transverse sections 31 on the surface of the reflector 20 intersect. In addition, as an example, the intersection area of the projections of the two transverse sections 31 on the surface of the reflector 20 is specifically located on the central axis of the radiation unit 10.
[0039] It should also be noted that since one of the vertical sections 32 of each feeding element 30 needs to be connected to the network signal transmission end, that is, the lengths of the two vertical sections 32 of each feeding element 30 are different, they can be set according to actual needs and are not limited here.
[0040] See also Figures 4 to 6 In one embodiment, the insulating fixing member 50 further includes an insulating plate 52. The insulating plates 52 are respectively connected to the four insulating sleeves 51, and the insulating plates 52 are arranged on the surfaces of the four radiating arms 12 away from the reflector 20. In this way, the four insulating sleeves 51 are respectively inserted into the sockets of the four radiating arms 12, so that the insulating plates 52 are fitted and fixed on the surfaces of the four radiating arms 12 away from the reflector 20, so that the insulating fixing member 50 can be easily installed and fixed on the radiating unit 10, and the assembly efficiency is high.
[0041] See also Figures 4 to 6 In one embodiment, the insulating fixing member 50 further includes at least one first insulating buckle 53 for clamping the radiation arm 12, at least one second insulating buckle 54 for clamping one of the transverse sections 31, and at least one third insulating buckle 55 for clamping another transverse section 31. The first insulating buckle 53, the second insulating buckle 54, and the third insulating buckle 55 are all connected to the insulating plate 52. In this way, the first insulating buckle 53 is clamped with the radiation arm 12, so that the insulating fixing member 50 can be stably installed on the radiation arm 12. Specifically, each radiation arm 12 is correspondingly connected to one, two, three, or other number of first insulating buckles 53, that is, the insulating fixing member 50 is respectively clamped and connected with the four radiation arms 12 through the first insulating buckles 53, so that the stable fixing effect of the insulating fixing member 50 can be achieved. In addition, one of the transverse sections 31 includes but is not limited to using one, two, three or other number of second insulating clips 54 for clipping and fixing, so that the insulating fixing member 50 can stably fix one of the feeders 30; in addition, similarly, another transverse section 31 includes but is not limited to using one, two, three or other number of third insulating clips 55 for clipping and fixing, so that the insulating fixing member 50 can stably fix the other feeder 30.
[0042] It should be noted that the "first insulating buckle 53, the second insulating buckle 54, the third insulating buckle 55 and the insulating sleeve 51" can be "a part of the insulating plate 52", that is, the "first insulating buckle 53, the second insulating buckle 54, the third insulating buckle 55 and the insulating sleeve 51" can be integrally formed with the "other parts of the insulating plate 52"; or it can be an independent component that can be separated from the "other parts of the insulating plate 52", that is, the "first insulating buckle 53, the second insulating buckle 54, the third insulating buckle 55 and the insulating sleeve 51" can be independently manufactured and then combined with the "other parts of the insulating plate 52" into a whole. Figure 6 As shown, in one embodiment, the "first insulating buckle 53, the second insulating buckle 54, the third insulating buckle 55 and the insulating sleeve 51" are a part of the "insulating plate 52" that is integrally formed.
[0043] See also Figures 4 to 6 In one embodiment, the insulating sleeve 51 used to insert the two vertical sections 32 of one feeder 30 is a first insulating sleeve, and the insulating sleeve 51 used to insert the two vertical sections 32 of the other feeder 30 is a second insulating sleeve. The top of the first insulating sleeve and the top of the second insulating sleeve both extend above the insulating plate 52, the distance from the top end face of the first insulating sleeve to the plate surface of the insulating plate 52 is h1, and the distance from the top end face of the second insulating sleeve to the plate surface of the insulating plate 52 is h2, and h1>h2. In this way, after the two vertical sections 32 of one of the feeders 30 are respectively inserted into the two first insulating sleeves, the transverse section 31 of one of the feeders 30 abuts against the end surface of the first insulating sleeve, and similarly, the transverse section 31 of the other feeder 30 abuts against the end surface of the second insulating sleeve. Since h1>h2, the transverse section 31 of one of the feeders 30 is higher than the transverse section 31 of the other feeder 30, and is staggered with the transverse section 31 of the other feeder 30 at an interval up and down, which can avoid the two from contacting each other and being electrically connected.
[0044] Please refer to Figure 1 In one embodiment, a convex portion 121 is provided at one end of the radiating arm 12 away from the balun 11. In this way, the radiation performance and intermodulation index of the integrated antenna unit can be improved by providing the convex portion 121. Of course, as an optional solution, the convex portion 121 may not be provided at one end of the radiating arm 12 away from the balun 11, but a concave portion or a structure of other shapes may be provided, which is not limited here and can be provided according to actual needs.
[0045] It should be noted that the "convex portion 121" can be "a part of the radiation arm 12", that is, the "convex portion 121" is integrally formed with the "other parts of the radiation arm 12"; it can also be an independent component that can be separated from the "other parts of the radiation arm 12", that is, the "convex portion 121" can be manufactured independently and then combined with the "other parts of the radiation arm 12" into a whole. Figure 1 As shown, in one embodiment, the “convex portion 121 ” is a part of the “radiating arm 12 ” that is integrally formed.
[0046] In one embodiment, the radiating unit 10 has two baluns 11 and two radiating arms 12. Thus, the two baluns 11 and the two radiating arms 12 are arranged and connected in a one-to-one correspondence, thus realizing the function of a single-polarized antenna.
[0047] See also Figures 1 to 3 In one embodiment, an antenna device includes the integrated antenna unit of any of the above embodiments.
[0048] The above antenna device, because the reflector 20 and the radiation unit 10 are integrally stamped and formed, that is, the reflector 20, the balun 11 and the radiation arm 12 are integrally stamped and formed, thereby realizing the integration of electromagnetic wave radiation and reflection, can simplify the structural composition of the integrated antenna unit, while reducing the complexity of the whole machine assembly process, making it easy to realize production automation, reducing production hours and improving the consistency and reliability of antenna assembly, greatly improving production efficiency and reducing production costs. In addition, the material composition of the antenna device can be minimized, and only the reflector 20 and the phase shifter 40 need to be assembled together to form an antenna device. The antenna device is simple and compact, maximizing the savings in material costs and assembly labor costs, and the antenna device is light in weight.
[0049] See also Figure 2 , Figure 3 and Figure 5 In one embodiment, the antenna device further includes a phase shifter 40 and a feeder 30. The phase shifter 40 is provided with a chamber 41, and a feed network board 42 located inside the chamber 41. The feeder 30 is connected to the radiation arm 12 for feeding, and the feeder 30 is also connected to the network signal transmission end of the feed network board 42. Specifically, the radiation unit 10 is arranged on the front side of the reflection plate 20, and the phase shifter 40 is arranged on the back side of the reflection plate 20. The feeder 30 passes through the stamping notch 21, penetrates through the wall of the chamber 41, extends into the chamber 41, and is connected to the network signal transmission end. In addition, each radiation unit 10 has two feeders 30, and each phase shifter 40 has two chambers 41. Feed network boards 42 are provided in the two chambers 41, and the two feeders 30 are respectively connected to the network signal transmission ends of the feed network boards 42 in the two chambers 41.
[0050] See also Figure 2 , Figure 3 and Figure 5In one embodiment, the antenna device further includes an insulating spacer 70. The insulating spacer 70 is disposed between the reflector 20 and the phase shifter 40. The reflector 20, the insulating spacer 70 and the phase shifter 40 are in close contact and fixedly connected through the insulating mounting member. In this way, the reflector 20 and the phase shifter 40 can be coupled and connected to ensure the coupling grounding effect of the two, and at the same time, the third-order intermodulation index of the antenna can meet the requirements.
[0051] See also Figure 7 , Figure 7 The schematic diagram of the structure of the antenna device of another embodiment of the present invention is shown. In one embodiment, the radiation unit 10 is a high-frequency radiation unit. At least two high-frequency radiation units are arranged on the reflection plate 20 at intervals, and the at least two high-frequency radiation units form a high-frequency array on the reflection plate 20.
[0052] See also Figure 7 Furthermore, the antenna device also includes at least one low-frequency radiation unit 60 arranged on the reflector 20. The low-frequency radiation unit 60 is located between two adjacent high-frequency radiation units. In this way, the low-frequency radiation unit 60 and the high-frequency radiation unit can form a multi-frequency array antenna with a common aperture, so that one antenna can support two frequency bands at the same time, so that multiple systems with different frequency bands can exist at the same time, and be compatible with multiple communication standards. Without increasing the antenna site and sky resources, frequency reuse of adjacent cells can be achieved, thereby improving network capacity, saving site resources, and reducing the number of antennas. Specifically, the working frequency band of the multi-frequency array antenna can be selected and implemented according to demand, for example, the low frequency is 690MHz-960MHz / 617MHz-960MHz, and the high frequency is selected and implemented between 1695MHz-2690MHz / 1427MHz-2690MHz.
