Description

Technical Field

[0001] This invention relates to the field of radio communication and navigation device technology, and specifically to a portable five-element array antenna mechanism. Background Technology

[0002] Portable five-element array antennas, as important electronic reconnaissance and communication equipment, typically cover a wide frequency range. To optimize performance and portability, they are often structurally divided into two frequency band units: G1 band antennas (1GHz-2GHz) and G2 band antennas (0.3GHz-1GHz). The two differ significantly in their physical structure: G1 antennas are compact, typically with a diameter not exceeding 300mm and a height not exceeding 100mm; while G2 antennas, due to their longer operating wavelength, have a much larger unfolded size than G1 antennas, reaching a diameter of 1500-2000mm and a height between 400-500mm. This larger size, while bringing performance advantages, also poses significant challenges to their transportation, storage, and rapid deployment in the field, making a foldable design an inevitable choice for this type of antenna structure.

[0003] However, existing portable antenna folding structures have the following shortcomings: First, there is a strong reliance on tools, the operation is cumbersome, and there is a risk of losing parts. Current technology mainly relies on conventional screws or non-detachable hand-tightening screws to lock and fix components. Using conventional screws requires special tools (such as screwdrivers), which are inconvenient to carry in the field. Moreover, after disassembly, the screws are easily lost, making it impossible to reassemble the equipment. Although hand-tightening screws avoid the need for tools, the operation of screwing them in and out is inefficient, and there are still problems with the management of small parts.

[0004] Secondly, there is a significant conflict between structural space and ease of operation. When using a hand-tightening screw solution, a large clearance area must be left around the screw to ensure sufficient operating space for the operator. This directly conflicts with the design goal of minimizing the structural size of antennas, especially small devices like the G1. For the G2 antenna's large folding mechanism, the inefficient threaded locking method also greatly prolongs the unfolding and folding time, failing to meet the requirements for rapid deployment.

[0005] Third, there is a lack of integrated, tool-free, quick-folding and locking solutions. Existing technologies fail to integrate the folding action with the locking or unlocking mechanism into a unified, interconnected design. The folding process is often separate from the locking process, requiring users to operate in steps, resulting in a complex process. More importantly, the locking force of existing locking structures is fixed, which cannot flexibly adapt to the varying locking force requirements of G2 band antennas due to different application scenarios, sizes, and weights, leading to poor versatility and compatibility. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a portable five-element array antenna mechanism with a simple and compact structure that can be quickly unfolded or folded without the need for tools and with the folding and locking process linked together.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A portable five-element array antenna mechanism includes a vibrator arm mounting base for mounting a G2 five-element array antenna and a five-element mounting base for mounting a G1 five-element array antenna. The top of the vibrator arm mounting base is connected to the five-element mounting base via a connecting part. The G2 five-element array antenna includes a plurality of first folding locking assemblies sequentially arranged around the vibrator arm mounting base. Each first folding locking assembly is hinged with a connecting rod, which is used to fold the connecting rod towards the five-element mounting base when stored, or to unfold and lock it outwards during operation. Each connecting rod has a second folding locking assembly at its outer end. Each second folding locking assembly is hinged with two vibrator arms, which are used to fold the two vibrator arms towards the connecting rod when stored, or to unfold and lock them outwards during operation.

[0008] As a further improvement to the above technical solution: The second folding locking assembly includes a wall box fixed to the end of the connecting rod, with a connecting seat at each of the upper and lower ends of the wall box; each connecting seat is rotatably connected to a rotating seat for fixing the vibrator arm via a rotating shaft; a limiting groove is provided on the connecting seat, and a protruding limiting piece is provided on the rotating seat for locking the limiting piece in the limiting groove when the arm is unfolded outward; a locking assembly is also provided on the connecting seat at the limiting groove for locking and limiting the limiting piece.

[0009] The limiting piece has a notch, and the edge of the notch has a limiting slope. The locking assembly includes a push rod that is movably inserted into the limiting groove. One end of the push rod extends into the connecting seat and abuts against the compression spring. The middle part of the push rod has an abutting slope that cooperates with the limiting slope, which is used to press the abutting slope against the limiting slope under the action of the compression spring to form a limiting lock.

[0010] The wall box is also provided with clamps at both ends to secure the folded vibrator arm; the wall box is also provided with a circuit board, which is electrically connected to two connectors through connectors.

[0011] Multiple conductive wear-resistant components are sleeved on the rotating shaft. These components are located between the rotating seat and the connecting seat to improve the rotational damping of the rotating seat and transmit the oscillator arm signal.

[0012] The first folding locking assembly includes a fixed base fixed to the periphery of the vibrator arm mounting base. A flip-up base for mounting a connecting rod is hinged to the fixed base via a movable shaft. The flip-up base has a limiting recess. The fixed base has a pressure plate, the middle of which is slidably mounted in the first slide groove of the fixed base via a sliding shaft. The tail of the pressure plate has a limiting shaft. The limiting shaft is slidably mounted in the second slide groove of the fixed base and extends outward to form a limiting fit with the limiting recess of the flip-up base. The limiting shaft is also connected to a tension spring plate in the fixed base via a tension spring, which, under the tension of the tension spring, causes the limiting shaft to press against the limiting recess to form a limiting lock.

[0013] An open retaining ring is fitted on the limiting shaft to prevent the limiting shaft from coming out of the second sliding groove.

[0014] Multiple wear-resistant plates are sleeved on the moving shaft, and the multiple wear-resistant plates are disposed between the fixed seat and the flip seat to improve the rotational damping of the flip seat.

[0015] The five-element mounting base is provided with multiple locking parts around its circumference to lock and fix the upward-folding connecting rod.

[0016] The five-element mounting base is provided with multiple snap-fit ​​mounting parts for snapping onto the G1 five-element array antenna.

[0017] Compared with the prior art, the advantages of the present invention are as follows: Firstly, the portable five-element array antenna mechanism disclosed in this invention enables the rapid folding or unfolding of multiple connecting rods and multiple vibrator arms of the G2 five-element array antenna by setting a first folding locking component and a second folding locking component, respectively. It no longer relies on conventional screws or non-loosening hand-tightening screws for locking and fixing components, greatly reducing the dependence on additional tools, making operation convenient and quick, and eliminating the risk of lost parts and difficult management of small parts.

[0018] Secondly, the portable five-element array antenna mechanism disclosed in this invention solves the prominent contradiction between structural space and ease of operation. The flip design of the first and second folding locking components eliminates the need for extra space for hand-tightening screws, effectively achieving the design goal of compact device size. Especially for the large folding mechanism of G antennas, it perfectly meets the requirements for rapid deployment, whether unfolding or folding for storage.

[0019] Thirdly, the portable five-element array antenna mechanism disclosed in this invention integrates the folding action with the locking or unlocking mechanism through the setting of a first folding locking component and a second folding locking component. The folding process and the locking process are no longer separated, so that the user does not need to operate in steps and the process is simple.

[0020] Fourth, the portable five-element array antenna mechanism disclosed in this invention uses a rotating seat to fix the vibrator arm and drive the vibrator arm to rotate around the connecting seat. When the limiting piece of the rotating seat is inserted into the limiting groove of the connecting seat, the vibrator arm is locked and limited during the deployment operation, avoiding signal transmission instability caused by the wobbling of the vibrator arm, which greatly improves the reliability and stability of the overall mechanism.

[0021] Fifth, this invention discloses a portable five-element array antenna mechanism. By setting a limiting slope, a separable dynamic locking structure is formed between the push rod and the connecting seat. Under the action of the spring, the push rod can tightly fit against the limiting slope, achieving self-locking of the rotating seat. When unlocking is needed, simply press the push rod manually to overcome the spring's force, causing the limiting slope to disengage, thus allowing the rotating seat to rotate. This self-locking structure is simple and reliable, achieving limiting locking without additional locking components, avoiding signal transmission instability caused by the swaying of the deployed vibrator arm, and greatly improving the overall reliability and stability of the mechanism. By selecting a suitable spring to change the locking force, it can flexibly adapt to different application scenarios, different sizes and weights of vibrator arms, greatly improving the device's versatility and compatibility.

[0022] Sixth, this invention discloses a portable five-element array antenna mechanism. By setting clamps at both ends of the wall box to securely fix the folded vibrator arm, the folded vibrator arm is locked in place, preventing its unfolding from affecting storage. A circuit board is placed inside the wall box to conduct the electrical signals of the vibrator arm, effectively isolating the external environment to prevent moisture damage to the circuit board, thus effectively improving the overall reliability and stability of the mechanism.

[0023] Seventh, this invention discloses a portable five-element array antenna mechanism. By incorporating conductive and wear-resistant components, it serves two purposes: firstly, to conduct electrical signals from the vibrating arm, and secondly, to provide damping for the rotating base. Furthermore, the conductive and wear-resistant components are interference-fitted with the rotating base, ensuring sufficient damping and preventing wobbling in any direction. Moreover, the conductive and wear-resistant components are made of brass, a material known for its high wear resistance, high lubricity, and excellent conductivity, making manual folding and rotation easier and facilitating signal transmission from the vibrating arm.

[0024] Eighthly, this invention discloses a portable five-element array antenna mechanism. By setting a flip-mounted fixed link and driving the link to rotate around the fixed mount, the sliding plate on the fixed mount engages with the limiting recess of the flip-mount, locking and limiting the link during deployment. This prevents signal transmission instability caused by link wobbling, greatly improving the overall reliability and stability of the mechanism. Furthermore, by setting a tension spring and a tension spring plate, the limiting shaft is tightened and fixed within the limiting recess of the flip-mount under the tension of the spring, achieving a limiting engagement with the flip-mount and realizing its self-locking function. This self-locking structure is simple and reliable, achieving limiting locking without additional locking components, greatly simplifying the installation process.

[0025] The ninth invention discloses a portable five-element array antenna mechanism, which prevents the limiting shaft from dislodging from the second slide groove by setting an open retaining ring, avoids the self-locking failure of the flip seat, and prevents the unfolded connecting rod from shaking and affecting signal transmission, thus greatly improving the stability and reliability of the overall mechanism.

[0026] The tenth invention discloses a portable five-element array antenna mechanism. By setting a wear-resistant plate and making the wear-resistant plate and the flip base interference fit to generate damping, the wear-resistant plate will not wobble in any direction, further strengthening the self-locking strength and avoiding self-locking failure.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] like Figures 1 to 17As shown, the portable five-element array antenna mechanism of this embodiment includes a vibrator arm mounting base 1 for mounting a G2 five-element array antenna and a five-element mounting base 2 for mounting a G1 five-element array antenna. The top of the vibrator arm mounting base 1 is connected to the five-element mounting base 2 through a connecting part 3. The G2 five-element array antenna includes a plurality of first folding locking components 4 arranged sequentially around the vibrator arm mounting base 1. Each first folding locking component 4 is hinged with a connecting rod 5, which is used to fold the connecting rod 5 toward the five-element mounting base 2 when stored, or to unfold and lock it outwards when in operation. Each connecting rod 5 has a second folding locking component 6 at its outer end. Each second folding locking component 6 is hinged with two vibrator arms 7, which are used to fold the two vibrator arms 7 toward the connecting rod 5 when stored, or to unfold and lock them outwards when in operation.

[0045] It should be noted that in this embodiment, there are two vibrating arms 7, which are symmetrically arranged vertically on the second folding locking assembly 6. The use of two vibrating arms 7 results in a wider signal radiation range. In other embodiments, only one vibrating arm 7 may be used, or multiple vibrating arms 7 may be used (similar to the frame of an umbrella). As long as the second folding locking assembly 6 is used to achieve the flipping and folding or unfolding and locking of the vibrating arms 7, such simple changes in quantity should fall within the scope of protection of this invention. Preferably, the connecting part 3 includes a vertically arranged connecting post and multiple reinforcing ribs surrounding the connecting post to enhance the connection strength between the vibrating arm mounting base 1 and the five-element mounting base 2.

[0046] The specific implementation principle is as follows: When storing and transporting the five-element array antenna mechanism, firstly, the second folding locking assembly 6 is unlocked, and force is applied to the two vibrating arms 7, causing the vibrating arms 7 to fold and move closer to the connecting rod 5, so that both vibrating arms 7, which were originally in the unfolded state, are in the retracted state; then, the first folding locking assembly 4 is unlocked, and force is applied to the connecting rod 5, causing the connecting rod 5 to drive the two retracted vibrating arms 7 on the connecting rod 5 to fold and move closer to the five-element mounting base 2, so that the connecting rod 5 and the two retracted vibrating arms 7 on the connecting rod 5 are in the retracted state. At this time, the five-element array antenna mechanism is... Figure 2 The folded state shown is compact, making it easy to carry and transport. During operation, the five-element array antenna mechanism needs to be unfolded. First, a pulling force is applied to the connecting rod 5, causing it to fold away from the five-element mounting base 2. After unfolding, the connecting rod 5 is locked by the first folding locking assembly 4, keeping it in the unfolded state. Then, force is applied to the two vibrating arms 7, causing them to fold away from the connecting rod 5. After unfolding, the vibrating arms 7 are locked by the second folding locking assembly 6, keeping them in the unfolded state. At this point, the five-element array antenna mechanism is... Figure 1 In the unfolded state shown, all the connecting rods 5 and the vibrator arm 7 are unfolded and locked in place, which makes the radiation range of the received and transmitted signals wider.

[0047] Through the aforementioned scientific and unique design, this portable five-element array antenna mechanism has the following advantages: Firstly, by setting up the first folding locking component 4 and the second folding locking component 6, the multiple connecting rods 5 and multiple vibrating arms 7 of the G2 five-element array antenna can be quickly folded or unfolded, eliminating the need to rely on conventional screws or non-loosening hand-tightening screws for locking and fixing the components. This greatly reduces the dependence on additional tools, making the operation convenient and quick, and eliminating the risk of lost parts and difficult management of small parts.

[0048] Secondly, it resolves the prominent contradiction between structural space and ease of operation. The flip-up design of the first folding locking assembly 4 and the second folding locking assembly 6 eliminates the need for extra space for hand-tightening screws, effectively achieving the design goal of compact equipment size. Especially for the large folding mechanism of the G2 antenna, it perfectly meets the requirements for rapid deployment, whether unfolding for operation or folding for storage.

[0049] Third, by setting the first folding locking component 4 and the second folding locking component 6, the folding action and the locking or unlocking mechanism are integrated and linked. The folding process and the locking process are no longer separated, so that users do not need to operate in steps and the process is simple.

[0050] like Figures 3 to 8 As shown, in this embodiment, the second folding locking assembly 6 includes a wall box 63 fixed to the end of the connecting rod 5. A connecting seat 61 is provided at each of the upper and lower ends of the wall box 63. Each connecting seat 61 is rotatably connected to a rotating seat 65 for fixing the vibrator arm 7 via a rotating shaft 64. A limiting groove 611 is provided on the connecting seat 61, and a protruding limiting piece 651 is provided on the rotating seat 65 for engaging in the limiting groove 611 during outward unfolding. A locking assembly is also provided on the connecting seat 61 at the limiting groove 611 to lock and limit the limiting piece 651. By setting the rotating seat 65 to fix the vibrator arm 7 and drive the vibrator arm 7 to rotate around the connecting seat 61, the limiting piece 651 of the rotating seat 65 engages in the limiting groove 611 of the connecting seat 61, locking and limiting the vibrator arm 7 during unfolding, preventing signal transmission instability caused by the wobbling of the vibrator arm 7, and greatly improving the reliability and stability of the overall mechanism.

[0051] like Figures 3 to 8 As shown, in this embodiment, a notch is provided on the limiting piece 651 (e.g., Figure 8As shown at point a), a limiting inclined surface 6511 is provided at the edge of the notch; the locking assembly includes a push rod 66 that is movably inserted into the limiting groove 611, and one end of the push rod 66 that extends into the connecting seat 61 abuts against the compression spring 67; the middle part of the push rod 66 is provided with an abutting inclined surface 661 that cooperates with the limiting inclined surface 6511, which is used to press the abutting inclined surface 661 against the limiting inclined surface 6511 under the pressing action of the compression spring 67 to form a limiting lock. By setting the limiting inclined surface 6511, the push rod 66 and the connecting seat 61 form a separable dynamic locking structure, so that the push rod 66 can be tightly fitted against the limiting inclined surface 6511 under the pushing force of the compression spring 67, realizing the self-locking of the rotating seat 65. When it is necessary to unlock, it is only necessary to manually press the push rod 66 to overcome the pushing force of the compression spring 67, so that the limiting inclined surface 6511 is disengaged, and the rotating seat 65 can rotate. This self-locking structure is simple and reliable, achieving limit locking without the need for additional locking components. It avoids signal transmission instability caused by the swaying of the deployed vibrator arm 7, greatly improving the overall reliability and stability of the mechanism. By selecting a suitable compression spring 67 to change the locking force, it can flexibly adapt to different application scenarios, different sizes and weights of the vibrator arm 7, greatly improving the versatility and compatibility of the device.

[0052] like Figures 3 to 8 As shown, in this embodiment, the wall box 63 is further provided with clamping parts 631 at both ends to securely fix the folded vibrator arm 7; the wall box 63 is also provided with a circuit board 632, which is electrically connected to two connecting seats 61 through connectors (such as screws, bolts, etc.). By providing clamping parts 631 at both ends of the wall box 63 to securely fix the folded vibrator arm 7, the folded vibrator arm 7 is locked, preventing the unfolded vibrator arm 7 from affecting storage. By providing a circuit board 632 inside the wall box 63 to conduct electrical signals from the vibrator arm 7, the external environment is effectively isolated to prevent the circuit board 632 from being damaged by moisture, effectively improving the reliability and stability of the overall mechanism.

[0053] like Figures 6 to 8 The diagram shows the force application process of the folding vibrator arm 7. First, a pushing force F1 is applied to the upper and lower push rods 66 simultaneously to unlock the limit lock formed by the compression spring 67. Then, a pushing force F2 is applied to the end of the vibrator arm 7 to make the vibrator arm 7 fold towards the five-element mounting base 2 until the vibrator arm 7 is inserted into the clamps 631 at both ends of the wall box 63 to achieve the limit lock after folding.

[0054] like Figure 5As shown, in this embodiment, a plurality of conductive wear-resistant components 62 are sleeved on the rotating shaft 64. These components 62 are positioned between the rotating seat 65 and the connecting seat 61 to improve the rotational damping of the rotating seat 65 and transmit the signal of the vibrator arm 7. By providing the conductive wear-resistant components 62, the electrical signal of the vibrator arm 7 is transmitted, and damping is provided for the rotating seat 65. Preferably, the conductive wear-resistant components 62 and the rotating seat 65 are interference-fitted, with a single-sided fit accuracy of 0.02-0.04 mm. This ensures that the rotating seat 65 has a certain damping, thereby preventing wobbling in any direction. Furthermore, the conductive wear-resistant components 62 are made of brass, which has high wear resistance, high lubricity, and excellent conductivity, making manual folding and rotation more convenient and facilitating the transmission of electrical signals by the vibrator arm 7.

[0055] like Figure 1 , 2 and Figures 9 to 17 As shown, in this embodiment, the first folding locking assembly 4 includes a fixed base 41 fixed to the periphery of the vibrator arm mounting base 1. A flip base 42 for mounting the connecting rod 5 is hinged to the fixed base 41 via a moving shaft 43. The flip base 42 is provided with a limiting recess 421. A pressing plate 413 is provided on the fixed base 41. The middle part of the pressing plate 413 is slidably mounted in the first sliding groove 411 of the fixed base 41 via a sliding shaft 4131. The pressing plate 413... The tail end is provided with a limiting shaft 4132; the limiting shaft 4132 is slidably installed in the second slide groove 412 of the fixed base 41, and the limiting shaft 4132 extends outward to form a limiting engagement with the limiting recess 421 of the flipping base 42; the limiting shaft 4132 is also connected to the tension spring plate 44 in the fixed base 41 through a tension spring 45, which is used to press the limiting shaft 4132 against the limiting recess 421 under the tension of the tension spring 45 to form a limiting lock. By setting the flipping base 42 to fix the connecting rod 5 and drive the connecting rod 5 to rotate around the fixed base 41, when the pressure plate 413 on the fixed base 41 is engaged with the limiting recess 421 of the flipping base 42, the connecting rod 5 is locked and limited during the unfolding operation, avoiding the unstable signal transmission caused by the shaking of the connecting rod 5, and greatly improving the reliability and stability of the overall mechanism. Furthermore, by setting a tension spring 45 and a tension spring plate 44, the limiting shaft 4132 is tightened and fixed in the limiting recess 421 of the flip seat 42 under the tension of the tension spring 45, thereby achieving a limiting engagement with the flip seat 42 and realizing the self-locking function of the flip seat 42. This self-locking structure is simple and reliable, and can achieve limiting and locking without additional locking parts, which greatly simplifies the installation process.

[0056] like Figures 9 to 17As shown, in this embodiment, an open retaining ring 46 is fitted on the limiting shaft 4132 to prevent the limiting shaft 4132 from dislodging from the second slide groove 412. By setting the open retaining ring 46 to prevent the limiting shaft 4132 from dislodging from the second slide groove 412, the self-locking failure of the flip seat 42 is avoided, which would cause the unfolded connecting rod 5 to shake and affect signal transmission, thus greatly improving the stability and reliability of the overall mechanism.

[0057] like Figures 9 to 17 As shown, in this embodiment, a plurality of wear-resistant plates 47 are sleeved on the moving shaft 43. The plurality of wear-resistant plates 47 are disposed between the fixed seat 41 and the flip seat 42 to improve the rotational damping of the flip seat 42. By setting the wear-resistant plates 47 and making the wear-resistant plates 47 and the flip seat 42 interference fit to generate damping, the wear-resistant plates 47 will not wobble in any direction, further strengthening the self-locking strength and avoiding self-locking failure.

[0058] like Figure 1 and Figure 2 As shown, in this embodiment, the five-element mounting base 2 is provided with multiple locking parts 21 around its circumference to lock and fix the upwardly folded connecting rod 5. By setting the locking parts 21 to lock the connecting rod 5 when it is stored, the extension of the connecting rod 5 is prevented from affecting storage.

[0059] like Figures 14 to 17 The diagram illustrates the force application process of the folding link 5. When the work is finished and the link 5 needs to be stored, a pushing force F3 is first applied to the pressing plate 413 to press the pressing plate 413, causing the pressing plate 413 to drive the sliding shaft 4131 to slide in the first sliding groove 411, and the limiting shaft 4132 to slide in the second sliding groove 412 to disengage from the limiting recess 421 of the flip seat 42 to release the lock on the flip seat 42. Then, a pushing force F4 is applied to the end of the link 5 to overcome the friction between the wear-resistant plate 47 and the fixed seat 41, and the link 5 rotates around the moving shaft 43 until it is engaged in the circumferential locking part 21 of the five-element mounting seat 2. At this time, the pushing force F3 applied to the pressing plate 413 is removed, and the sliding shaft 4131 and the limiting shaft 4132 will return to the initial position of the corresponding sliding groove of the fixed seat 41 under the action of the tension spring 45, completing the folding and storage of the link 5.

[0060] like Figure 1 and Figure 2 As shown in this embodiment, the five-element mounting base 2 is provided with multiple snap-fit ​​mounting parts 22 for snapping onto the G1 five-element array antenna. By providing multiple snap-fit ​​mounting parts 22, the G1 five-element array antenna can be detachably mounted on the five-element mounting base 2, which facilitates the assembly and disassembly of the G1 five-element array antenna and greatly improves the installation efficiency.

[0061] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
