[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] See Figures 1 to 4 , Figure 1 and Figure 2 The diagram shows two different viewpoint structural schematics of a radiating element according to an embodiment of this application. Figure 3 It shows Figure 2 The diagram shows an enlarged view of the structure at point A. Figure 4 It shows Figure 1 The exploded structural diagram shown is provided. One embodiment of this application provides a radiating unit comprising: two first radiating arms (10a, 10b) of the same polarization and a feed balun 20. The feed balun 20 includes a first feed support column 21 and a first feed element 22. The top of the first feed support column 21 is connected to one of the first radiating arms 10a and is integrated into the structure; the top of the first feed element 22 is connected to the other first radiating arm 10b and is integrated into the structure; the first feed element 22 and the first feed support column 21 are provided with a first gap and are coupled to each other. Specifically, the radiating unit includes a first cable 30. The first cable 30 has a first inner conductor 31 and a first outer conductor 32 arranged circumferentially around the first inner conductor 31; the first inner conductor 31 is electrically connected to the bottom of the first feed element 22, and the first outer conductor 32 is electrically connected to the first feed support column 21.

[0033] The aforementioned radiating element integrates the top of the first feed support column 21 with one of the first radiating arms 10a, forming a single integrated structure, and the top of the first feed element 22 with the other first radiating arm 10b, also forming a single integrated structure. Furthermore, the first feed element 22 and the first feed support column 21 are provided with a first gap and coupled to each other. Thus, the feed balun 20 employs a parallel dual-line transmission structure to feed the two first radiating arms (10a, 10b) of the same polarization, where the first feed support column 21 serves as the first transmission line and the first feed element 22 serves as the second transmission line. Compared to radiating elements in related technologies, this design simplifies the structure, miniaturizes the product, reduces the weight of the radiating element, thereby reducing the antenna weight, and simultaneously improves isolation.

[0034] In some embodiments, the radiating element includes a low-frequency radiating element for radiating low-frequency signals and / or a high-frequency radiating element for radiating high-frequency signals. It can be an array of at least one low-frequency radiating element, an array of at least one high-frequency radiating element, an adjacent array of at least one low-frequency array and at least one high-frequency array, an array of high-frequency radiating elements between two adjacent low-frequency radiating elements, and preferably a high-frequency radiating element nested within a low-frequency radiating element. It can be any low-frequency radiating array interspersed among multiple different and / or identical high-frequency arrays, etc. The specific configuration can be determined by a technician according to system performance requirements, such as gain requirements.

[0035] In some embodiments, the radiating element can be either a single-polarized radiating element or a dual-polarized radiating element, which can be selected and set according to actual needs. This embodiment will specifically take a dual-polarized radiating element as an example, but it is not limited to this. Each polarization direction has two radiating arms, such as two first radiating arms (10a, 10b) of the same polarization. The four radiating arms are divided into two pairs, each pair of radiating arms operates in the same polarization direction and is supported on the feed balun 20. Specifically, the two pairs of radiating arms operate in two mutually orthogonal polarization directions, such as a +45° polarization direction and a -45° polarization direction, or perpendicular polarizations intersecting, etc.

[0036] Please see Figures 1 to 4In one embodiment, the radiating unit further includes two second radiating arms (40a, 40b) of the same polarization and a second cable 50. The feed balun 20 also includes a second feed support column 23, a second feed element 24, and a base 25. The top of the second feed support column 23 is connected to one of the second radiating arms 40a and is an integral structure. The top of the second feed element 24 is connected to the other second radiating arm 40b and is an integral structure. The second feed element 24 and the second feed support column 23 are provided with a second gap and are coupled to each other. The bottom of the first feed column and the bottom of the second feed column are both connected to the base 25. In addition, the second cable 50 has a second inner conductor 51 and a second outer conductor 52 arranged circumferentially around the second inner conductor 51. The second inner conductor 51 is electrically connected to the bottom of the second feed element 24, and the second outer conductor 52 is electrically connected to the second feed support column 23.

[0037] In this arrangement, two first radiating arms (10a, 10b) of the same polarization are arranged on one diagonal, and two second radiating arms (40a, 40b) of the same polarization are arranged on the other diagonal, resulting in a cross-shaped arrangement of the four radiating arms. Furthermore, the shapes of the two first radiating arms (10a, 10b) can be identical or different; they can be arranged symmetrically or asymmetrically about the centerline of the radiating element, depending on the specific requirements. Similarly, the shapes of the two second radiating arms (40a, 40b) can be identical or different; they can be arranged symmetrically or asymmetrically about the centerline of the radiating element, depending on the specific requirements.

[0038] In some embodiments, the first cable 30 and the second cable 50 are each independently configured, and both are, but are not limited to, coaxial cables. The coaxial cable has an inner conductor and an outer conductor that is coaxial with and insulated from the inner conductor. The outer conductor of the coaxial cable is grounded, and the inner conductor is used to output a feed signal to a feed element or receive an antenna signal input from the feed element.

[0039] Please see Figures 1 to 4 In one embodiment, the two first radiating arms (10a, 10b) are provided with a third gap and coupled to each other; and / or, the two second radiating arms (40a, 40b) are provided with a fourth gap and coupled to each other. In this way, the two radiating arms of the same dipole are coupled at the intersection, which can broaden the bandwidth and increase the number of resonant points.

[0040] In one embodiment, one of the first radiating arms 10a has a first connecting portion 10a1 connected to the top of the first feed support column 21. The first connecting portion 10a1 forms a first groove 10a11, and the other first radiating arm 10b is coupled to the groove wall of the first groove 10a11. Thus, the other first radiating arm 10b is coupled to the groove wall of the first groove 10a11, specifically by extending into the first groove 10a11 and forming a third gap with the groove wall, such that the groove wall of the first groove 10a11 partially surrounds the outside of the other first radiating arm 10b. Compared to plane-to-plane coupling, this provides a better coupling effect. Optionally, the groove wall of the first groove 10a11 may be, but is not limited to, an arc shape, a polygon, or other regular or irregular shapes. Arc shapes include, for example, semicircles or semi-ellipses, and polygons include, but are not limited to, triangles, quadrilaterals, and pentagons.

[0041] Similarly, one of the second radiating arms 40a has a second connecting portion 40a1 connected to the top of the second feed support column 23. The second connecting portion 40a1 is connected to the top of the second feed support column 23, and the second connecting portion 40a1 forms a second groove 40a11. The other second radiating arm 40b is coupled to the groove wall of the second groove 40a11. In this way, the other second radiating arm 40b is coupled to the groove wall of the second groove 40a11, specifically, for example, extending into the interior of the second groove 40a11 and forming a fourth gap with the groove wall of the second groove 40a11, so that the groove wall of the second groove 40a11 partially surrounds the exterior of the other second radiating arm 40b. Compared with the plane-to-plane coupling method, the coupling effect is better. Optionally, the groove wall of the second groove 40a11 may be, but is not limited to, an arc shape, a polygon shape, or other regular and irregular shapes.

[0042] In some embodiments, for a first radiating arm 10a with a first connecting portion 10a1, the width W of the first connecting portion 10a1 is greater than the width of the other parts of the first radiating arm 10a, thereby making the structural strength sufficiently large, and at the same time, there is a sufficiently large space on the first connecting portion 10a1 to form the first groove 10a11.

[0043] Similarly, for the second radiating arm 40a with the second connecting portion 40a1, the width of the second connecting portion 40a1 is greater than the width of the other parts of the second radiating arm 40a.

[0044] Please see Figure 3 and Figure 4In one embodiment, the top of the first power supply support column 21 has a first clearance hole 211 that communicates with the first groove 212, and another first radiating arm 10b passes through the first clearance hole 211. Furthermore, the top of the second power supply support column 23 has a second clearance hole 231 that communicates with the second groove 232, and another second radiating arm 40b passes through the second clearance hole 231.

[0045] It should be noted that the "first connecting part 10a1" can be "a part of the first radiating arm 10a", that is, the "first connecting part 10a1" and "other parts of the first radiating arm 10a" can be integrally formed; or it can be an independent component that can be separated from "other parts of the first radiating arm 10a", that is, the "first connecting part 10a1" can be manufactured independently and then combined with "other parts of the first radiating arm 10a" to form a whole.

[0046] It should be noted that the "second connecting part 40a1" can be "a part of the second radiating arm 40a", that is, the "second connecting part 40a1" and "other parts of the second radiating arm 40a" can be integrally formed; or it can be a separate component that can be separated from "other parts of the second radiating arm 40a", that is, the "second connecting part 40a1" can be manufactured independently and then combined with "other parts of the second radiating arm 40a" to form a whole.

[0047] The shapes of the first radiating arms (10a, 10b) and the second radiating arms (40a, 40b) are set according to actual needs. They can be set as regular shapes, such as long strips, rectangular plates, circular plates, or rods, or as irregular shapes. Furthermore, the shapes of the two first radiating arms (10a, 10b) can be the same or different. Similarly, the shapes of the two second radiating arms (40a, 40b) can be the same or different.

[0048] In one embodiment, one of the first radiating arms 10a is further provided with a first elongated arm segment 10a2 connected to the first connecting portion 10a1; the other second radiating arm 40b is further provided with a second elongated arm segment 40a2 connected to the second connecting portion 40a1. Thus, the two first radiating arms (10a, 10b) and the two second radiating arms (40a, 40b) combine to form a cross shape, which is small in size and occupies little space; in addition, the relatively small feed balun 20 is easy to nest in a multi-frequency array and has little impact on the high-frequency array.

[0049] Please refer to Figure 6 , Figure 6The radiation pattern of a radiating element according to an embodiment is shown. The low-frequency radiating element is designed according to the radiating element design of this application embodiment and is combined with the high-frequency radiating element to form a multi-frequency array. Simulation results show that the high-low frequency mutual coupling is small, resulting in excellent radiation performance. Furthermore, the multi-system, multi-standard antenna is lightweight.

[0050] Please see Figures 1 to 4 In one embodiment, the first feed support post 21 is integrally formed with one of the first radiating arms 10a; the first feed element 22 is integrally formed with the other first radiating arm 10b. Furthermore, the second feed support post 23 is integrally formed with one of the second radiating arms 40a; the second feed element 24 is integrally formed with the other second radiating arm 40b. This allows for mass production with high efficiency. In addition, the simple product structure enables miniaturization, reducing the weight of the radiating elements and thus the antenna weight, while also improving isolation.

[0051] It should be noted that the one-piece molding method in this embodiment includes, but is not limited to, die casting one-piece molding, sheet metal one-piece molding, milling one-piece molding, bending one-piece molding, forging one-piece molding, etc., and can be flexibly adjusted and set according to actual needs.

[0052] In some embodiments, the first feeder 22 includes, but is not limited to, various forms such as feeder plates, feeder boards, feeder columns, and feeder poles. Similarly, the second feeder 24 includes, but is not limited to, various forms such as feeder plates, feeder boards, feeder columns, and feeder poles.

[0053] In one embodiment, the first power supply component 22 includes a first vertical segment 221 and a first horizontal segment 222 connected to the first vertical segment 221. The first horizontal segment 222 is connected to another first radiating arm 10b. A first gap is formed between the first vertical segment 221 and the first power supply support column 21. Specifically, the first vertical segment 221, the first horizontal segment 222, and the other first radiating arm 10b are integrally formed. Furthermore, the shape and size of the first vertical segment 221, the first horizontal segment 222, and the other first radiating arm 10b can be flexibly adjusted and set according to actual needs. As an example, the axial cross-sectional dimensions and shapes of the first vertical segment 221, the first horizontal segment 222, and the other first radiating arm 10b can be kept consistent or flexibly adjusted and set according to actual needs, for example, by bending a thin sheet metal strip. The first horizontal segment 222 and the other first radiating arm 10b are set as an integral structure, i.e., there is no clear division of their respective lengths. In one embodiment, the first power supply element 22 may also include only the first vertical segment 221, that is, the first horizontal segment 222 is omitted. The horizontal arm segments connected above the first vertical segment 221 are all first radial arms 10b.

[0054] Furthermore, the second power supply component 24 includes a second vertical segment 241 and a second horizontal segment 242 connected to the second vertical segment 241. The second horizontal segment 242 is connected to another second radial arm 40b. A second gap is formed between the second vertical segment 241 and the second power supply support column 23. Specifically, the second vertical segment 241, the second horizontal segment 242, and the other second radial arm 40b are integrally formed. Moreover, the shapes and dimensions of the second vertical segment 241, the second horizontal segment 242, and the other second radial arm 40b can be flexibly adjusted and set according to actual needs. As an example, the axial cross-sectional dimensions and shapes of the second vertical segment 241, the second horizontal segment 242, and the other second radial arm 40b can be kept consistent or flexibly adjusted and set according to actual needs, for example, by bending a thin sheet metal strip. The second horizontal segment 242 and the other second radial arm 40b are set as an integrated structure, i.e., there is no clear division of their respective lengths. In one embodiment, the second power supply element 24 may also include only the second vertical segment 241, that is, the second horizontal segment 242 is omitted. The horizontal arm segments connected above the second vertical segment 241 are all second radial arms 40b.

[0055] In one embodiment, the radiating unit further includes a first insulating isolator (not shown) and a second insulating isolator (not shown). The first insulating isolator is disposed between the first feeder 22 and the first feed support post 21. The second insulating isolator is disposed between the second feeder 24 and the second feed support post 23. This not only ensures that the first feeder 22 is securely mounted on the first feed support post 21, but also ensures that the first gap between the first feeder 22 and the first feed support post 21 is stable and reliable; similarly, this not only ensures that the second feeder 24 is securely mounted on the second feed support post 23, but also ensures that the second gap between the second feeder 24 and the second feed support post 23 is stable and reliable.

[0056] In some embodiments, the first insulating isolator and the second insulating isolator are each provided independently, including but not limited to being configured as a medium snap-fit ​​or as a fastener made of other insulating materials as required.

[0057] Please see Figures 1 to 4 In one embodiment, a first mounting groove 212 is formed on the side of the first feed support post 21, and the first feed element 22 is disposed in the first mounting groove 212. Furthermore, a second mounting groove 232 is formed on the side of the second feed support post 23, and the second feed element 24 is disposed in the second mounting groove 232. Thus, the radiating element structure is compact, which is beneficial for product miniaturization, thereby improving the isolation of the array antenna.

[0058] Please see Figures 1 to 4In one embodiment, the first vertical segment 221 of the first power supply component 22 is arranged parallel to the first power supply support column 21. Furthermore, the second vertical segment 241 of the second power supply component 24 is arranged parallel to the second power supply support column 23. Thus, the first gap between the first vertical segment 221 and the first power supply support column 21 at all positions from top to bottom remains consistent, which facilitates precise control of the size of the first gap; similarly, the second gap between the second vertical segment 241 and the second power supply support column 23 at all positions from top to bottom remains consistent, which facilitates precise control of the size of the second gap.

[0059] In one embodiment, the radiating unit further includes a reflector (not shown in the figure). The bottom of the first feed support column 21 and the bottom of the second feed support column 23 are mounted on the reflector.

[0060] Please see Figures 1 to 4 In one embodiment, the first feed element 22 is disposed on the first feed support post 21 on the side opposite to the second feed support post 23. Furthermore, the second feed element 24 is disposed on the second feed support post 23 on the side opposite to the first feed support post 21. Thus, the first feed element 22 and the second feed element 24 are isolated from each other by the first feed support post 21 and the second feed support post 23, thereby improving the isolation between polarizations.

[0061] Specifically, please refer to Figure 5 , Figure 5 This paper shows a measured diagram of the polarization isolation of a radiating element according to an embodiment of this application. Figure 5 It can be seen that the isolation between the two polarizations is below -30dB.

[0062] In some embodiments, by adjusting the size of the first gap and the size of the second gap, as well as adjusting the width of the first feed element 22 and the width of the second feed element 24, the matching bandwidth of the radiating element can be tuned accordingly to achieve optimal impedance matching.

[0063] In some embodiments, the height of the first feed support column 21 is, for example, set to one-quarter wavelength of the center frequency of the radiating element's operating frequency band. Furthermore, the height of the second feed support column 23 is the same as or substantially the same as the height of the first feed support column 21.

[0064] Please see Figures 1 to 4 In some embodiments, an antenna includes a radiating element from any of the above embodiments.

[0065] The aforementioned antenna integrates the top of the first feed support post 21 with one of the first radiating arms 10a, forming a single integrated structure, and the top of the first feed element 22 with the other first radiating arm 10b, also forming a single integrated structure. Furthermore, the first feed element 22 and the first feed support post 21 are provided with a first gap and coupled to each other. Thus, the feed balun 20 employs a parallel dual-line transmission structure to feed the two first radiating arms (10a, 10b) of the same polarization, where the first feed support post 21 serves as the first transmission line and the first feed element 22 serves as the second transmission line. Compared to radiating elements in related technologies, this design simplifies the structure, miniaturizes the product, reduces the weight of the radiating element, thereby reducing the antenna weight and improving isolation.
