Description

Technical Field

[0001] The present invention relates to the technical field of Luneburg lens fixing, and in particular to a Luneburg lens and an array antenna. Background Art

[0002] The Luneburg lens is a wide-angle omnidirectional reflector that can reflect various large-angle incident electromagnetic waves back in parallel. Compared with a triangular reflector, it can produce a larger radar cross-section and a wider secondary radiation directional coverage angle.

[0003] Luneburg lenses are widely used in array antennas, which are antenna systems composed of several identical antennas arranged according to a certain rule. If they are arranged in a straight line or a plane, they become a linear array or a plane array. The electromagnetic field radiated by the array antenna is the sum (vector sum) of the radiation fields of each unit of the antenna array. With the rapid development of science and technology, the development of Luneburg lens array antennas is also very rapid.

[0004] The existing Luneburg lens is usually fixed in the groove of the support plate and then fixed with glue, which has two disadvantages:

[0005] 1) When the feed source reflects the wave, part of it is reflected by the Luneburg lens ball support plate, so the Luneburg lens cannot completely absorb it, resulting in a decrease in the performance of the Luneburg lens;

[0006] 2) This fixing method is not reliable, and the Luneburg lens ball has the risk of shaking or even falling.

[0007] For example, the patent application number "CN200580009846.0" discloses an easy-to-install Luneburg sphere antenna device, which is formed by combining a hemispherical Luneburg sphere and a radio wave reflector; in this solution, the Luneburg sphere antenna device includes: an antenna fixing assembly frame, and a fixing device such as a bolt for detachably fixing the radio wave reflector of the above antenna device to the antenna fixing assembly frame. However, the assembly frame in this patent solution will block the feed source, thereby reducing the performance of the Luneburg sphere antenna. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the problem that the Luneburg lens is not firmly fixed.

[0009] The present invention solves the above technical problems through the following technical means:

[0010] A Luneburg lens, comprising:

[0011] A Luneburg lens assembly, wherein the Luneburg lens assembly is composed of a plurality of Luneburg lens monomers fixedly connected into an integral structure;

[0012] A plurality of fixing members, wherein the upper ends of the fixing members are fixedly connected to at least one Luneburg lens monomer as a whole, a threaded hole is provided at one end of the fixing member away from the Luneburg lens monomer, and the fixing member is fixed to an external connection component through the threaded hole to form an array antenna;

[0013] By assembling several Luneburg lens monomers into a whole, and then fixing them to one end of a fixing member, and fixing the other end of the fixing member to an external device through a threaded hole, this fixing method can fix multiple Luneburg lens monomers at one time, and the fixing method is stable and suitable for promotion and use;

[0014] Moreover, the upper end of the fixing part contacts with the Luneburg lens monomer and lifts the Luneburg lens monomer, which also reduces the contact area between the fixing part and the Luneburg lens monomer, better avoiding the fixing part reflecting a part of the reflected wave of the feed source, so that the Luneburg lens monomer can completely absorb the reflected wave of the feed source, thereby improving the working efficiency of the Luneburg lens monomer.

[0015] As a further solution of the present invention: the Luneburg lens assembly is composed of a Luneburg lens monomer, and the bottom of the Luneburg lens monomer is symmetrically fixedly connected to two fixing members.

[0016] As a further solution of the present invention: the Luneburg lens monomer is a Luneburg lens with a diameter of 80 mm.

[0017] As a further solution of the present invention: the Luneburg lens assembly is composed of two Luneburg lens monomers fixedly connected together, and the two Luneburg lens monomers are fixedly connected together to form a whole;

[0018] There are four fixing members, and the tops of every two fixing members are fixedly connected to the bottom of one of the Luneburg lens monomers as a whole;

[0019] Alternatively, the number of the fixing members is two, and the two fixing members are respectively fixedly connected to the bottoms of the two Luneburg lens monomers as a whole.

[0020] As a further solution of the present invention: the Luneburg lens assembly is composed of four Luneburg lens monomers, the four Luneburg lens monomers form a quadrilateral structure, and the diameter of the Luneburg lens monomer is 40 mm; two Luneburg lens monomers symmetrical along the diagonal of the quadrilateral structure are respectively fixedly connected to the upper end of the fixing piece.

[0021] As a further solution of the present invention: the bottom of the Luneburg lens monomer is fixedly connected to the fixing member as a whole, or the side of the Luneburg lens monomer is fixedly connected to the fixing member.

[0022] An array antenna based on the Luneburg lens, further comprising:

[0023] A connecting assembly, wherein the connecting assembly is provided with a first through hole, the first through hole matches with a threaded hole, and a threaded rod is inserted to fix the connecting assembly and the fixing member;

[0024] An angle adjustment track, wherein the angle adjustment track is slidably connected to the connection assembly;

[0025] A second support plate, wherein the top of the second support plate is fixedly connected to the bottom of the angle adjustment track by bolts;

[0026] The cover body is fixedly connected to the top of the second support plate by bolts or screws.

[0027] As a further solution of the present invention: the connecting assembly includes a first supporting plate, a first through hole, a fixing frame, an angle adjustment sliding assembly, and a feed source; the first supporting plate includes a transverse plate and a longitudinal plate fixedly connected into an integral shape, a plurality of first through holes matching the threaded holes are opened on the top of the transverse plate, the longitudinal plate is affixed to and fixed to the fixing frame, the fixing frame is slidably connected to the angle adjustment track through the angle adjustment sliding assembly, and the side of the longitudinal plate facing away from the fixing frame is affixed to and fixed to the feed source.

[0028] As a further solution of the present invention: the angle adjustment sliding assembly is fixedly connected to the fixed frame, and a steel column roller and a bearing are fixedly arranged on the side surface of the angle adjustment sliding assembly that are opposite to each other. The steel column roller is arranged at the bottom of the angle adjustment sliding assembly and is used to slide in cooperation with the angle adjustment track. A fastening screw is arranged inside the steel column roller, and the fastening screw is tightened.

[0029] As a further solution of the present invention: the angle adjustment track includes a first track and a second track, and the divergent surfaces of each two symmetrical angle adjustment tracks are also provided with a first track for accommodating the fastening screws passing through, and the track spacing of the first track is smaller than that of the second track.

[0030] By sliding the steel column roller on the second track, the pitch angle of multiple Luneburg lens units can be adjusted at the same time, and the adjustment efficiency is higher. The back-to-back surfaces of every two symmetrical angle adjustment tracks are also provided with a first track for accommodating the fastening screws to pass through and be exposed, and the track spacing of the first track is smaller than that of the second track, so that the fastening screws can be tightened conveniently, thereby preventing rolling, thereby effectively fixing the fixing frame.

[0031] The advantages of the present invention are:

[0032] 1. The present invention assembles a plurality of Luneburg lens monomers into a whole, which is then fixedly connected to one end of a fixing member, and the other end of the fixing member is fixedly connected to an external device through a threaded hole. This fixing method can fix a plurality of Luneburg lens monomers at one time, and the fixing method is stable and suitable for popularization and use.

[0033] 2. The present invention only requires the upper end portion of the fixing part to contact with the Luneburg lens monomer and lift the Luneburg lens monomer, which also reduces the contact area between the fixing part and the Luneburg lens monomer, and better avoids the fixing part reflecting a part of the reflected wave of the feed source, so that the Luneburg lens monomer can completely absorb the reflected wave of the feed source, thereby improving the working efficiency of the Luneburg lens monomer.

The back-to-back surfaces of every two symmetrical angle adjustment tracks are also provided with a first track for accommodating the fastening screws to pass through and be exposed, and the track spacing of the first track is smaller than that of the second track, so that the fastening screws can be tightened conveniently, thereby preventing rolling, and thus the fixing frame can be effectively fixed.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1

[0049] See also Figure 1 , Figure 1 The isometric diagram of a Luneburg lens composed of a Luneburg lens monomer provided in Example 1 of the present invention, a Luneburg lens, comprising:

[0050] A Luneburg lens assembly 1, wherein the Luneburg lens assembly 1 is composed of a plurality of Luneburg lens monomers 101 fixedly connected into an integral structure;

[0051] A plurality of fixing members 2, the upper ends of the fixing members 2 are fixedly connected to at least one Luneburg lens monomer 101 as a whole, a threaded hole is provided at one end of the fixing member 2 away from the Luneburg lens monomer 101, and the fixing member 2 is fixed to an external connection component through the threaded hole to form an array antenna.

[0052] The fixing member 2 may be a column, such as a rectangular parallelepiped structure or a cylindrical structure. Of course, it may also be other irregular shapes. However, considering practical application and aesthetics, the fixing member 2 is preferably a rectangular parallelepiped structure.

[0053] At the same time, in order to ensure the stability of the fixing member 2, a reinforcing rod may be fixedly connected between the two fixing members 2.

[0054] Preferably, in the solution disclosed in the embodiment of the present invention, refer to Figure 1 The Luneburg lens assembly 1 can be composed of a Luneburg lens monomer 101. At this time, the bottom of the Luneburg lens monomer 101 is symmetrically fixed to two fixing members 2 to form an integral structure, and then connected to external connecting components through threaded holes opened in the fixing members 2 to form an array antenna.

[0055] Furthermore, the Luneburg lens monomer 101 is a Luneburg lens with a diameter of 80 mm.

[0056] Preferably, see Figure 2 or Figure 3 , Figure 2 A first axonometric schematic diagram of a Luneburg lens composed of two Luneburg lens monomers provided in Example 1 of the present invention, Figure 3 The second axonometric schematic diagram of the Luneburg lens composed of two Luneburg lens monomers provided in Example 1 of the present invention, as a scheme disclosed in the embodiment of the present invention, the Luneburg lens assembly 1 can be composed of two Luneburg lens monomers 101, and the two Luneburg lens monomers 101 are fixedly connected together to form a whole. At the same time, in order to ensure that the Luneburg lens monomers 101 can be better stabilized, the number of the fixing parts 2 is preferably four, and the top of every two fixing parts 2 is fixedly connected to the bottom of one of the Luneburg lens monomers 101 as a whole.

[0057] In one embodiment of the present invention, Figure 2 and Figure 3 It is only for reference and Figure 2 and Figure 3 The difference is that a reinforcing rod is fixedly arranged between every two fixing members 2 or a reinforcing rod is not fixedly arranged.

[0058] It should be noted that, see Figure 4 , Figure 4 The third axonometric schematic diagram of the Luneburg lens composed of two Luneburg lens monomers provided in Example 1 of the present invention, when the Luneburg lens assembly 1 can be composed of two Luneburg lens monomers 101, the number of the fixing members 2 can also be two, and the two fixing members 2 are respectively fixedly connected to the bottom of the two Luneburg lens monomers 101 as a whole, which can also play a fixing role.

[0059] It should be emphasized that when the Luneburg lens assembly 1 can be composed of two Luneburg lens monomers 101, the number of the fixing member 2 can also be one, but the fixing effect will be worse in this case.

[0060] See also Figure 5 , Figure 5The isometric diagram of the Luneburg lens composed of four Luneburg lens monomers provided in Example 1 of the present invention, the Luneburg lens assembly 1 can also be composed of four Luneburg lens monomers 101, in which case the four Luneburg lens monomers 101 form a quadrilateral structure ( Figure 5 The diameter of the Luneburg lens monomer 101 is 40 mm; two Luneburg lens monomers 101 symmetrical along the diagonal of the quadrilateral structure are fixedly connected to the top of the fixing member 2 respectively.

[0061] In addition, although the fixing member 2 in this embodiment is not limited to being fixedly connected to the bottom of the Luneburg lens monomer 101 as a whole, for example, it can also be connected to the side of the Luneburg lens monomer 101 (in this case, it is necessary to ensure that there is a certain distance between the end of the fixing member 2 away from the Luneburg lens monomer 101 and the lowest end of the Luneburg lens monomer 101), in this case, the threaded hole can be a blind hole or a first through hole.

[0062] Working principle:

[0063] By assembling a plurality of Luneburg lens monomers into a whole, and then fixing and connecting them to one end of the fixing member 2, and fixing and connecting the other end of the fixing member 2 to an external device through a threaded hole, this fixing method can fix a plurality of Luneburg lens monomers at one time, and the fixing method is stable and suitable for promotion and use;

[0064] One end of the fixing member 2 is connected to the Luneburg lens monomer 101 as a whole, and the other end is connected to the external equipment through a threaded hole, so that the Luneburg lens monomer 101 can be effectively fixed, thereby overcoming the problem of unreliable fixation of the Luneburg lens. Only the upper end of the fixing member 2 needs to contact with the Luneburg lens monomer 101 and lift the Luneburg lens monomer 101, which also reduces the contact area between the fixing member 2 and the Luneburg lens monomer 101, and better avoids the fixing member 2 from reflecting a part of the reflected wave of the feed source, so that the Luneburg lens monomer 101 can completely absorb the reflected wave of the feed source, thereby improving the working efficiency of the Luneburg lens monomer 101.

[0065] Example 2

[0066] See also Figure 6 , Figure 7 and Figure 8 , Figure 6 A first isometric schematic diagram of an array antenna provided in Embodiment 2 of the present invention, Figure 7 A second isometric schematic diagram of the array antenna provided in Embodiment 2 of the present invention, Figure 8 A third axonometric schematic diagram of the array antenna provided in Embodiment 2 of the present invention, Fig. 9 Fig. 9 The isometric diagram of the first track of the angle adjustment sliding assembly in the array antenna provided in Example 2 of the present invention, an array antenna based on the Luneburg lens described in Example 1, further comprising:

[0067] A connecting component 3, wherein the connecting component 3 is provided with a first through hole, the first through hole matches with the threaded hole, and a threaded rod is inserted to fix the connecting component 3 and the fixing member 2;

[0068] An angle adjustment track 4, wherein the angle adjustment track 4 is slidably connected to the connection component 3;

[0069] A second support plate 5, the top of the second support plate 5 is fixedly connected to the bottom of the angle adjustment track 4 by bolts;

[0070] The cover body is fixedly connected to the top of the second support plate 5 by bolts or screws.

[0071] In the solution disclosed as an embodiment of the present invention, Figure 7 and Figure 8 In the embodiment, the connection component 3 includes a first support plate 301 , a first through hole 302 , a fixing frame 303 , an angle adjustment sliding component 304 , and a feed source 305 .

[0072] See also Figure 7 and Figure 8 The first support plate 301 includes a transverse plate and a longitudinal plate fixedly connected into an integral shape, and the angle between the transverse plate and the longitudinal plate is 120-145 degrees. A plurality of first through holes matching the threaded holes are opened on the top of the transverse plate. The longitudinal plate is in contact with the fixing frame 303 and fixed together by bolts or screws. The fixing frame 303 is slidably connected to the angle adjustment track 4 through an angle adjustment sliding assembly 304. The side of the longitudinal plate facing away from the fixing frame 303 is in contact with the feed source 305 and fixed together by bolts or screws. This ensures that the distance between the fixing frame 303 and the Luneburg lens monomer 101 is small.

[0073] As an embodiment of the present invention, the transverse plate is also evenly spaced apart with a plurality of second through holes and first through holes 302 located directly below the Luneburg lens monomer 101 . The spacing between the second through holes and the first through holes 302 is relatively large to prevent blocking the signal of the Luneburg lens monomer 101 .

[0074] Furthermore, a slot hole is formed between every two second through-hole fixing frames 303 on the transverse plate, and the slot hole is connected to the outside world at the side away from the longitudinal plate. Taking the figure as an example, the top view of the slot hole is a "concave" shape rotated 90 degrees to the left.

[0075] See also Figure 7 and Figure 8The angle adjustment sliding assembly 304 is fixedly connected to the fixing frame 303 by bolts. A steel column roller 3041 and a bearing 3042 are bolted on the side surface of the angle adjustment sliding assembly 304 that are away from each other. The steel column roller 3041 is arranged at the bottom of the angle adjustment sliding assembly 304 and is used to slide with the angle adjustment track 4. A fastening screw is arranged inside the steel column roller 3041. The fastening screw is tightened so that the steel column roller 3041 cannot slide relative to the angle adjustment track 4, so that the direction of the Luneburg lens monomer 101 can be adjusted.

[0076] See also Fig.10 and Fig.11 , Fig.10 This is an axonometric schematic diagram of a second track of an angle adjustment sliding assembly in an array antenna provided in Embodiment 2 of the present invention, Fig.11 The isometric diagram of the angle adjustment sliding assembly in the array antenna provided in Example 2 of the present invention, as a scheme disclosed in the embodiment of the present invention, the angle adjustment track 4 includes a first track 401 and a second track 402.

[0077] A base is provided at the bottom of the angle adjustment track 4, and is fixedly connected to the top bolts of the second support plate 5 through the base. The top of the angle adjustment track 4 is a concave arc structure, and degrees are engraved on the diverging surfaces of every two symmetrical angle adjustment tracks 4. A second track 402 is provided on the sides close to each other of every two symmetrical angle adjustment tracks 4. The second track 402 cooperates with the steel column roller 3041 to accommodate the sliding of the steel column roller 3041, so that the pitch angle of the Luneburg lens monomer 101 can be adjusted; and the pitch angle of the Luneburg lens monomer 101 can be read and adjusted through the degrees engraved on the diverging surface of the angle adjustment track 4.

[0078] The back surfaces of each two symmetrical angle adjustment rails 4 are also provided with a first rail 401 for accommodating the fastening screws to pass through and be exposed, and the track spacing of the first rail 401 is smaller than that of the second rail 402, so that the fastening screws can be tightened conveniently, thereby preventing 3041 from rolling, thereby effectively fixing the fixing frame 303.

[0079] It should be noted that a plurality of evenly distributed rollers with brake devices may be fixedly provided at the bottom of the second support plate 5 by bolts, so that the direction of the Luneburg lens monomer 101 can be adjusted by rotating the second support plate 5 .

[0080] Working principle: By sliding the steel column roller 3041 on the second track 402, the pitch angles of multiple Luneburg lens monomers 101 can be adjusted simultaneously, and the adjustment efficiency is higher. The reverse side of each two symmetrical angle adjustment tracks 4 is also provided with a first track 401 for accommodating the fastening screws passing through and exposed, and the track spacing of the first track 401 is smaller than that of the second track 402, so that the fastening screws can be tightened conveniently, thereby preventing 3041 from rolling, and thus the fixing frame 303 can be effectively fixed.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
