[0002] Antennas are devices that receive or transmit electromagnetic waves and are widely used in many fields such as communications, radar, television, broadcasting, navigation, remote sensing, and telemetry. As the application fields of antennas become more and more extensive, the applications of antennas are also becoming more and more diversified, requiring antenna products to have high efficiency, high radiation power, good resonance performance, and wide bandwidth. However, the bandwidth of an antenna is proportional to its size, so it is necessary to design antennas with compact structure and wide bandwidth.
[0003] Narrow-pitch broadband antennas are microstrip antenna structures with advantages such as simple structure, low process requirements, small size, low cost, and good performance. They have been widely used in modern wireless communication technology and microwave technology. Narrow-pitch broadband antennas use a multi-unit microstrip antenna structure and can achieve a wider bandwidth by using the mutual coupling between multiple unit antennas.

The four unit bodies 10 and the support plate 20 are an integrally formed structure.
[0037] The technical solution of this embodiment is applied, and the unit body 10 includes a plate body 11 and a vertical plate 12. The vertical plate 12 is connected to the edge of the plate body 11, and the vertical plate 12 is arranged perpendicular to the plate body 11. A first avoidance hole 111 is arranged at the edge of the plate body 11, and a second avoidance hole 121 is arranged on the vertical plate 12. The first avoidance hole 111 and the second avoidance hole 121 are connected, and the support plate 20 is arranged in the four second avoidance holes 121.

The four unit bodies 10 and the support plate 20 are an integrally formed structure. Through the above-mentioned setting, the integrally formed unit body 10 and the support plate 20 are adopted, combined with the distribution of the specific first metal layer 31 and the second metal layer 32 and the structural design of the first conductive structure 41 and the second conductive structure 42, the lightweight and high integration of the antenna vibrator are achieved, while the electrical performance of the antenna vibrator is guaranteed. This not only simplifies the manufacturing process of the antenna vibrator and reduces the cost, but also improves the mechanical strength and stability of the antenna vibrator. Therefore, the technical direction of this embodiment effectively solves the problem of high processing cost of the antenna vibrator in the related art.
[0038] This design makes the antenna vibrator structure more compact and can effectively reduce the overall volume of the antenna. Due to its compact design, this antenna vibrator can significantly reduce the antenna space occupied by the device, making the device thinner and lighter, while also facilitating the integration and installation of the antenna, and improving the flexibility and practicality of the device design.
[0039] Specifically, the first metal layer 31 and the second metal layer 32 of the present embodiment are both implemented by electroplating, which greatly reduces the number of solder joints and effectively improves the intermodulation index.
[0040] like Figures 1 to 6 As shown, in this embodiment, each unit body 10 and support plate 20 are made of plastic. The choice of plastic material not only reduces the weight of the antenna vibrator, but also reduces the manufacturing cost, making the antenna vibrator more economical in mass production. Using plastic antenna vibrators can not only reduce the load of the device, making it more stable during flight or movement, but also reduce the energy consumption of the device and extend the battery life, which is of great significance for remote monitoring of drones, long-term operation of unmanned vehicles, and widespread deployment of Internet of Things devices.
[0041] The unit body 10 and the support plate 20 are processed by injection molding. After cooling and molding, they are first demolded by upper and lower molds, and then by left and right molds.
[0042] like Figure 6 and Figure 7 As shown, in this embodiment, the second conductive structure 42 includes a first conductive segment 421, a second conductive segment 422, a third conductive segment 423, a fourth conductive segment 424 and a fifth conductive segment 425 connected in sequence, the first conductive segment 421 and the fifth conductive segment 425 are both located on the upper surface of the support plate 20 and on both sides of the first conductive structure 41, the second conductive segment 422 and the fourth conductive segment 424 are both penetrated on the support plate 20, and the third conductive segment 423 is located on the lower surface of the support plate 20. The above arrangement enables the third conductive segment 423 to be spaced apart from the first conductive structure 41. Specifically, the design of this complex second conductive structure 42 can effectively improve the bandwidth of the antenna and enhance the signal receiving capability. It is suitable for scenarios requiring high frequency stability and wide frequency band operation. Through the design of this second conductive structure 42, the antenna can achieve more stable signal transmission and wider frequency band coverage, which is important for high-speed data transmission and low-latency communication of 5G communications. At the same time, it can also meet the requirements of future communication technologies for frequency band flexibility and signal stability.

The design of the rectangular plate makes the layout of the antenna vibrator more regular, which is convenient for the integration of the antenna array. At the same time, the design of the first avoidance hole 111 at the corner can ensure the assembly of the support plate 20 and the electrical performance of the antenna, which is suitable for equipment that requires high-density integration, such as base stations, satellite communication equipment, etc. The design of the first avoidance hole 111 at the corner of the rectangular plate effectively avoids signal interference and short-circuit problems, so that the antenna vibrator can maintain good performance in high-density integrated equipment, which plays an important role in the signal coverage of the base station and the stability of satellite communications, and also provides the possibility for further miniaturization and integration of the antenna.
[0044] like Figures 1 to 5As shown, in this embodiment, four vertical plates 12 are arranged to form a first rectangular structure, the outer edges of the four plate bodies 11 form a second rectangular structure, and the angle bisector of the first rectangular structure is perpendicular to the angle bisector of the second rectangular structure. This structural design can optimize the radiation characteristics of the antenna and improve the radiation efficiency of the antenna. It is suitable for scenarios that require optimization of signal coverage and improvement of data transmission rate, such as indoor Wi-Fi, outdoor wireless network coverage, etc. And in this way, the radiation characteristics of the antenna vibrator can be optimized, which not only improves the efficiency of signal reception and transmission, but also can achieve a wider signal coverage range, which plays an important role in the seamless connection of indoor Wi-Fi and the wide coverage of outdoor wireless networks, and also provides support for the popularization and application of wireless communication technology.
[0045] Specifically, the second metal layer 32 is located on the inner surface of the first rectangular structure.
[0046] like Figure 2 and Figure 8 As shown, in this embodiment, the support plate 20 includes a plate body 21 and four protrusions 22 arranged at the edge of the plate body 21. The four protrusions 22 are arranged at intervals, and a protrusion 22 is arranged in each second avoidance hole 121. The provision of the protrusions 22 can increase the mechanical strength of the support plate 20 and prevent damage due to external forces during use. It is suitable for equipment that needs to work in harsh environments, such as industrial automation equipment, outdoor monitoring equipment, etc. Specifically, the provision of the protrusions 22 connects the four vertical plates 12 together, thereby improving the mechanical strength of the antenna vibrator, so that the antenna can maintain long-term stable operation in industrial automation equipment and outdoor monitoring equipment, reducing the maintenance cost of the equipment, and also providing reliable protection for the application of the antenna in harsh environments.

This design can further optimize the electrical performance of the antenna and improve the anti-interference ability of the antenna, and is suitable for scenes that need to work in complex electromagnetic environments, such as aviation communications. By adding the third conductive structure 43 and the fourth conductive structure 44, the electrical performance of the antenna is further optimized, and the anti-interference ability of the antenna is improved, which has an important impact on the stability of communication, and also provides technical guarantees for the application of the antenna in complex electromagnetic environments.

[0049] According to another aspect of the present application, a narrow spacing broadband antenna is provided, such as Figures 9 to 11 As shown, the narrow-spacing broadband antenna of this embodiment includes an antenna vibrator, and the antenna vibrator is the above-mentioned antenna vibrator.
