[0037] Various embodiments of this application will be described more fully below. This application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this application to the specific embodiments disclosed herein, but rather this application should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this application.
[0038] In the following, the terms “comprising” or “may include” as used in the various embodiments of this application indicate the presence of the disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. Furthermore, as used in the various embodiments of this application, the terms “comprising,” “having,” and their cognates are intended only to indicate a particular feature, number, step, operation, element, component, or combination of the foregoing, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing, or the possibility of adding one or more combinations of features, numbers, steps, operations, elements, components, or combinations of the foregoing.
[0039] In various embodiments of this application, the expression "or" or "at least one of A and / or B" includes any combination or all combinations of the words listed simultaneously. For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.
[0040] The terms used in the various embodiments of this application (such as "first," "second," etc.) may modify various constituent elements in the various embodiments, but do not limit the corresponding constituent elements. For example, the above terms do not limit the order and / or importance of the elements. The above terms are only used for the purpose of distinguishing one element from other elements. For example, a first user device and a second user device refer to different user devices, although both are user devices. For example, without departing from the scope of the various embodiments of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.
[0041] like Figure 1-3 As shown, this application provides a command and control antenna, including: a base 1; an antenna module 2 disposed on the base 1 for receiving and transmitting signals; a cover 3 connected to the base 1 to jointly define a cavity 6 for accommodating the antenna module 2; the surface of the cover 3 includes a curved surface, and the projected area of the side of the cover 3 away from the base 1 on the base 1 is smaller than the projected area of the side of the cover 3 close to the base 1 on the base 1; an input / output interface 4 disposed on the base 1, one end of the input / output interface 4 being electrically connected to the antenna module 2, and the other end of the input / output interface 4 being used for connecting to external devices; wherein, the side of the base 1 away from the cover 3 has a mounting part 11 for mounting the command and control antenna to an external component, and the mounting direction of the mounting part 11 is different from the orientation of the input / output interface 4. This application achieves a more compact overall structure for the command and control antenna through the structural design of the base 1, antenna module 2, radome 3, and input / output interface 4. This allows for a more rational layout of internal components within a limited space. Furthermore, the curved radome 3, which is narrower at the top and wider at the bottom, enhances the overall strength and durability of the radome 3. By aligning the mounting direction of the mounting part 11 of the base 1 with the orientation of the input / output interface 4, interference or damage to the input / output interface 4 during installation is avoided, further improving the stability and reliability of the equipment.
[0042] like Figure 1-6 As shown, the mounting part 11 includes a flange with multiple circumferentially arranged first mounting holes 111. The through direction of the first mounting holes 111 is the mounting direction of the mounting part 11. This application uses a flange as the mounting part 11 and installs the command antenna through multiple circumferentially arranged first mounting holes 111, thereby enhancing the connection strength between the flange and external components. This ensures that the antenna remains stable under various operating conditions, effectively resists interference from external factors such as wind and vibration, reduces the impact of shaking or displacement on antenna performance, and guarantees the stability and reliability of communication.
[0043] The first mounting hole 111 includes threaded holes, smooth holes, tapered holes, elliptical holes, or oblong holes. This application utilizes the first mounting hole 111 to encompass various types, such as threaded holes, smooth holes, tapered holes, elliptical holes, or oblong holes, enabling the command antenna to adapt to diverse installation environments and external components. For example, when external components are pre-threaded, threaded holes can be used directly for installation, simplifying the operation and ensuring a secure connection; if external components are fastened using bolts and nuts, smooth holes provide a perfect fit. The use of multiple types of first mounting holes 111 significantly expands the application range of the command antenna and reduces installation difficulties caused by mismatched mounting holes.
[0044] In this embodiment, the first mounting hole 111 includes a light hole.
[0045] like Figure 1-3 As shown, the enclosure 3 includes a dome 31 and a base frame 32, which are connected together. The base frame 32 is connected to the base 1. The height h1 of the dome 31 is greater than the height h2 of the base frame 32. This application, by designing the dome 31 to be higher than the base frame 32, provides the antenna module 2 with more installation space and allows the electromagnetic waves radiated by the antenna to obtain a more ideal propagation path in space, reducing signal reflection and scattering during propagation. This enhances the signal transmission strength and reception sensitivity, effectively expanding the communication range and improving the signal transmission quality and stability of the command antenna in complex environments.
[0046] Specifically, the ratio of the height h1 of the dome 31 to the height h2 of the base frame 32 is between 5 and 8. When the ratio of the height h1 of the dome 31 to the height h2 of the base frame 32 is between 5 and 8, the enclosure not only provides the antenna module 2 with a larger installation space, but also enables the electromagnetic waves radiated by the antenna to obtain a more ideal propagation path in space.
[0047] In this design, the thickness d1 of the dome 31 is less than the thickness d2 of the base frame 32. This design reduces the blocking effect of the dome 31 on electromagnetic waves by making the dome 31 thinner than the base frame 32. The thinner dome 31 reduces energy loss during electromagnetic wave propagation, allowing signals to be transmitted and received more smoothly through the enclosure 3, thereby improving the signal transmission efficiency of the command antenna, making communication faster and more stable, reducing signal delay and attenuation, and ensuring good communication quality even at long distances or in complex electromagnetic environments. Furthermore, the higher portion of the dome 31 can withstand greater external pressure and impact, distributing the force to the base frame 32, which then evenly transmits it to the base 1. The thicker base frame 32 provides sufficient support, preventing deformation or damage to the enclosure 3 under external forces, thus greatly improving the stability of the equipment.
[0048] In this embodiment, the thickness of the dome 31 is the thickness of the dome sidewall.
[0049] like Figure 1-6 As shown, the sidewall surface of the dome 31 includes an inwardly recessed curved surface 311. In terms of signal performance, this application, through the design of the recessed curved surface 311 on the sidewall surface of the dome 31, allows for more precise control of the electromagnetic wave propagation path, guiding the electromagnetic wave to propagate in a predetermined direction and pattern. Simultaneously, by rationally designing the shape and size of the recessed curved surface 311, the antenna's radiation pattern can be optimized, resulting in higher signal gain in specific directions, thereby expanding the communication coverage and improving the antenna's performance in complex electromagnetic environments. In terms of structural strength, the recessed curved surface 311 design alters the stress distribution of the enclosure 3 to a certain extent. When the enclosure 3 is subjected to external pressure or impact, the recessed curved surface 311 can disperse stress, avoiding localized stress concentration, thereby improving the structural strength and deformation resistance of the dome 31.
[0050] like Figure 5 , 6 As shown, one of the base frame 32 and the base 1 is provided with a limiting ring 33, and the other is provided with a limiting groove 12. The limiting groove 12 is adapted to the limiting ring 33 to limit the positioning of the base frame 32 and the base 1. This application provides precise positioning guidance for the installation of the base frame 32 and the base 1 through the matching design of the limiting ring 33 and the limiting groove 12. During the installation process, simply align the limiting ring 33 with the limiting groove 12 and insert it to quickly and accurately complete the initial positioning of the base frame 32 and the base 1. This avoids the installation deviation and repeated adjustments caused by the difficulty of manual alignment in traditional installation methods, greatly shortens the installation time, and improves the installation efficiency. It is especially suitable for large-scale production or scenarios requiring rapid deployment.
[0051] In this embodiment, the bottom frame 32 is provided with a limiting ring 33, and the base 1 is provided with a limiting groove 12. The limiting groove 12 is adapted to the limiting ring 33 to realize the limiting of the bottom frame 32 and the base 1.
[0052] like Figure 5 , 6As shown, the bottom frame 32 has multiple circumferentially arranged second mounting holes 321, and the base 1 has multiple circumferentially arranged third mounting holes 12. The multiple second mounting holes 321 and the multiple third mounting holes 12 correspond one-to-one. Each corresponding second mounting hole 321 and third mounting hole 12 is equipped with a fastener 8 for achieving a detachable connection between the bottom frame 32 and the base 1. This application achieves the connection between the bottom frame 32 and the base 1 through a one-to-one correspondence between multiple circumferentially arranged second mounting holes 321 and third mounting holes 12, and by means of fasteners 8. This multi-point connection method greatly enhances the connection strength between the two. The detachable connection achieved through the cooperation of fasteners 8, second mounting holes 321, and third mounting holes 12 makes the installation and removal of the bottom frame 32 and the base 1 simple and quick. When it is necessary to maintain, repair, or replace internal components of the antenna, simply loosening the fasteners 8 allows for easy separation of the bottom frame 32 and the base 1, without the need for complicated tools or procedures. After maintenance, the two can be quickly and accurately reconnected, greatly shortening maintenance time, improving maintenance efficiency, and reducing maintenance costs.
[0053] like Figure 3 As shown, the cavity 6 includes the inner cavity of the base 1 and the inner cavity of the housing 3. The antenna module 2 includes a radio frequency module 21 and a control module 22. The control module 22 is electrically connected to the radio frequency module 21 and is used to drive the radio frequency module 21 to receive and transmit signals. The radio frequency module 21 is located in the inner cavity of the housing 3, and the control module 22 is located in the inner cavity of the base 1. By placing the radio frequency module 21 and the control module 22 in the inner cavities of the housing 3 and the base 1, respectively, this application achieves modular division of functions and makes full use of the internal space of the base 1 and the housing 3, making the overall structure of the command antenna more compact.
[0054] During maintenance of the command antenna of this application, only the corresponding modules need to be repaired or replaced, without the need for large-scale disassembly of the entire antenna module 2, which greatly shortens the maintenance time and reduces the maintenance cost. Furthermore, the radio frequency module 21 is placed in the inner cavity of the cover 3, and the cover 3 can provide a certain electromagnetic shielding and protection for the radio frequency module 21, thereby improving the stability and reliability of the signal transmission quality of the command antenna.
[0055] The radio frequency module 21 includes various types of antennas. In this embodiment, the radio frequency module 21 includes a first type of antenna and a second type of antenna. The first type of antenna includes multiple patch antennas stacked in sequence. The second type of antenna includes a feed port and a cross-shaped element. The cross-shaped element is connected to the feed port. The feed port includes an outer conductor of a slot balun and an inner conductor of a slot balun. The outer conductor of the slot balun is disposed outside the inner conductor of the slot balun. The outer conductor of the slot balun and the inner conductor of the slot balun extend along the height direction of the enclosure.
[0056] The control module 22 includes a microcontroller and a power module. The microcontroller is used to control the switching of the RF module and adjust the signal processing parameters; the power module is used to provide power to the RF module.
[0057] The mounting section 11 is equipped with a shock-absorbing pad (not shown in the figure) for absorbing vibration. The shock-absorbing pad reduces the transmission of vibration to the antenna module 2, avoiding problems such as loose components and poor contact caused by vibration, thereby ensuring the stability of signal reception and transmission and ensuring that the communication quality is not affected by vibration.
