LUNEBERG LENS ANTENNA WITH ELECTRICALLY ADJUSTABLE POSITION FEEDER AND LUNEBERG LENS ANTENNA GROUP TECHNICAL FIELD This disclosure relates to the technical field of communication devices and, in particular, to a Luneberg lens antenna with an electrically adjustable position feeder and a group of Luneberg lens antennas. BACKGROUND In a traditional Luneberg lens antenna, when it is necessary to change the radiation angle of a feed by adjusting its tilt angle, tower operators must climb a tower to adjust the pitch angle of a clamp on-site to achieve the optimal effect, which is time-consuming and laborious. In adverse weather conditions such as wind or snow, this method of adjustment increases operational difficulty, and manual adjustment is prone to error. To reduce the operational difficulty for operators and prevent them from having to climb a tower to adjust an antenna each time, some commercially available Luneberg lens antennas allow for the electrical adjustment of a feed position. These are described in technical schematics in Chinese patent application no. 202020408992.2, applied for by the applicant and titled Electrically Adjustable Luneberg Lens Antenna, this type of Luneberg lens antenna includes: a feeder, a Luneberg lens, a mounting frame, and a position adjustment mechanism. A spherical surface is formed on the Luneberg lens, and the Luneberg lens is fixed relative to the mounting frame. The position adjustment mechanism includes a tilting frame, a drive rod, a drive base, and a transmission device. The drive rod is rotatably mounted on the mounting frame. The transmission device is also mounted on the mounting frame and configured to rotate the drive rod. The drive base is connected to the drive rod and can move in a straight line along the drive rod by rotating the drive rod.The tilting frame is between the mounting frame and the Luneberg lens; a tilting frame is connected to the tilting frame, and a rotating end that can rotate in relation to the Luneberg lens is formed in the tilting rod, so that the frame... The tilting frame of the LR / Rnn / eznz / e / Yi antenna can oscillate around the center of the spherical surface of the Luneberg lens. The feeder is mounted on the tilting frame, and a connecting rod is articulated between the tilting frame and the drive base. This structure, which adjusts the feeder position by tilting the frame, is not stable, and the tilting rod must be mounted using hinges, which is inconvenient to assemble. Given the limitations of the existing Luneberg lens antenna, it is urgent to improve its design. COMPENDIUM The present disclosure aims to provide a Luneberg lens antenna with an electrically adjustable position feeder, which has the advantages of simple structure, reasonable design, good stability in adjusting a feeder position, convenient assembly and low production cost. A technical solution for the Luneberg lens antenna with an electrically adjustable feeder is implemented as follows. The Luneberg lens antenna with the electrically adjustable feeder may include a reflector plate, a feeder, a Luneberg lens, and a position adjustment mechanism. The position adjustment mechanism includes a mounting plate, a motor, a guide rail, a sliding block, a connecting base, a screw, and a movable base. One position of the mounting plate is relatively fixed to position A of the Luneberg lens, and a surface of the mounting plate, facing the Luneberg lens, is a mounting surface. The guide rail is mounted on the mounting plate and between the mounting surface and the Luneberg lens.Both ends of the screw are rotatably mounted on the mounting plate, and the orthographic projections of one screw shaft and one guide rail shaft onto the mounting surface are parallel to each other. The motor is fixed to the mounting plate and configured to rotate the screw. The movable base has a threaded hole, and this threaded hole is connected to the screw via a threaded connection. The reflective plate is positioned between the Luneberg lens and the guide rail. The sliding block is mounted on the reflective plate and connected by a sliding fit to the guide rail. One end of the connecting base is connected to the movable base, and the other end is connected to the reflective plate. The feeder is mounted on a surface of the reflective plate facing the Luneberg lens.

The motor and the screw are located between the left and right guide rails. The sliding block includes a left sliding block and a right sliding block. Both the left and right sliding blocks have a sliding portion. The sliding portion of the left sliding block engages with the left guide rail groove, and the sliding portion of the right sliding block engages with the right guide rail groove. Furthermore, the guide rail grooves on the left and right guide rails have a linear structure, as do the sliding parts on the left and right sliding blocks. One end of the connecting base is fixedly connected to the movable base, and the other end is fixedly connected to the reflective plate. Furthermore, the cross-sections of the guide rail slots in the left guide rail and the right guide rail have an inverted T-shaped structure, and the cross-sections of the sliding parts in the left sliding block and the right sliding block also have an inverted T-shaped structure.

The reflector plate of the Luneberg lens antenna with an electrically adjustable feeder can slide along the guide rail via the sliding block, allowing the feeder's position on the reflector plate to be adjusted relative to the Luneberg lens. When the feeder's position is adjusted, the motor drives the screw to rotate, causing the screw's movable base to move in a straight line along the screw's axis. This, in turn, drives the reflector plate to move along the guide rail.In this way, the reflective plate can move in a direction determined by the shape of the guide rail, instead of being connected by a rotating shaft to adjust the position relative to the Luneberg lens, which has good operational stability and convenient assembly; therefore, the Luneberg lens antenna with the electrically adjustable position feeder has the advantages of.

DETAILED DESCRIPTION OF THE ACHIEVEMENTS Implementation 1 As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a Luneberg lens antenna with an electrically adjustable position feeder of this embodiment includes: a plate 1 LR / Rnn / eznz / e / Yi reflective, a feeder 2, a Luneberg lens 3, and a position adjustment mechanism 4. The position adjustment mechanism 4 includes a mounting plate 41, a motor 42, a guide rail 43, a sliding block 44, a connecting base 45, a screw 46, and a movable base 47. A position of the mounting plate 41 is relatively fixed to a position of the Luneberg lens 3; a surface of the mounting plate 41, facing the Luneberg lens 3, is a mounting surface 411. The Luneberg lens 3 is a spheroid Luneberg lens, and the mounting surface 411 is a plane. The guide rail 43 is mounted on the mounting plate 41 and between the mounting surface 411 and the Luneberg lens 3. Both ends of screw 46 are rotatably mounted on mounting plate 41, and the orthographic projections, on mounting surface 411, of a shaft of screw 46 and a shaft of guide rail 43 are parallel to each other.The motor 42 is fixed to the mounting plate 41 and configured to rotate the screw 46. The movable base 47 has a threaded hole 472, and this threaded hole is connected to the screw 46. The reflective plate 1 is positioned between the Luneberg lens 3 and the guide rail 43. The sliding block 44 is mounted on the reflective plate 1 and is connected by a sliding fit to the guide rail 43. One end of the connecting base 45 is connected to the movable base 47, and the other end is connected to the reflective plate 1. The feeder 2 is mounted on a surface of the reflective plate 1 that faces the Luneberg lens 3, and this surface is reflective.The reflective plate 1 of the Luneberg lens antenna, with its electrically adjustable position feeder, can slide along the guide rail 43 via the sliding block 44. This allows the position of the feeder 2 on the reflective plate 1 to be adjusted relative to the Luneberg lens 3. When the position of the feeder 2 is adjusted, the motor 42 drives the screw 46 to rotate, causing the movable base 47 of the screw 46 to move in a straight line along the screw 46's axis. The connecting base 45 on the movable base 47 then drives the reflective plate 1 to move along the guide rail 43. In this way, the reflective plate 1 can move in a direction determined by the shape of the guide rail 43, rather than being connected by a rotating shaft to adjust its position relative to the Luneberg lens 3. This provides good operational stability and convenient assembly.Therefore, the Luneberg lens antenna with electrically adjustable position feeder has the advantages of simple structure, reasonable design, good stability in feeder position adjustment, convenient assembly, and low production cost.

To allow the Luneberg lens antenna feeder 2 with an electrically adjustable position feeder to move in a straight line to adjust the position, as shown in Figure 2 and Figure 3, the guide rail slots 433 in the left guide rail 431 and the right guide rail 432 have a linear structure, and the sliding parts 443 in the left sliding block 441 and the right sliding block 442 also have a linear structure; one end of the connecting base 45 is fixedly connected to the movable base 47, and the other end of the connecting base 45 is fixedly connected to the reflective plate 1. To make a more reasonable assembly structure for the left guide rail 431 and the right guide rail 432 in correspondence with the left sliding block 441 and the right sliding block 442, as shown in Figure 2 and Figure 3, the cross-sections of the guide rail slots 433 in the left guide rail 431 and the right guide rail 432 have an inverted T-shaped structure, and the cross-sections of the sliding parts 443 in the left sliding block 441 and the right sliding block 442 also have a T-shaped structure. LR / Rnn / eznz / e / Yi Inverted T. The sliding fit between the sliding part 443 of the inverted T-shaped structure and the guide rail slot 433 of the inverted T-shaped structure is good, and there is no risk of derailment when the Luneberg lens antenna with an electrically adjustable position feeder is mounted obliquely. To make the Luneberg lens mounting structure more practical, as shown in Figure 1, Figure 2, and Figure 4, the Luneberg lens antenna with the electrically adjustable position feeder further includes a cover housing 5 and a bracket 6. The cover housing 5 comprises an upper housing half 51 and a lower housing half 52. The upper housing half 51 is formed by an upper fixing ring 511 along one edge of its housing opening, the lower housing half 52 is formed by a lower fixing ring 521 along one edge of its housing opening, and the upper housing half 51 is assembled with the lower housing half 52 to form a mounting chamber. The Luneberg lens 3 is mounted in the mounting chamber.There are two fixing lugs 61 arranged on the bracket 6, and both the upper fixing ring 511 of the upper half housing 51 and the lower fixing ring 521 of the lower half housing 52 are fixedly connected to the two fixing lugs 61 on the bracket 6. The mounting plate 41 is fixed to the bracket 6. To prevent dust and moisture and prolong the service life of the Luneberg lens antenna with electrically adjustable position feeder, as shown in Figure 1, the Luneberg lens antenna with electrically adjustable position feeder also includes an outer housing 7. The outer housing 7 is fixed to the support 6. The position adjustment mechanism 4, the reflector plate 1, and the feeder 2 are all located within the outer housing 7; and an edge of a housing opening in the outer housing 7 is fixed to an outer surface of the lower housing 52. Implementation 2 The difference between this embodiment and embodiment 1 is that, as shown in Figures 5 and 6, both the left guide rail 8 and the right guide rail 9 have an arc-shaped strip structure, and the center of the left guide rail 8, the center of the right guide rail 9, and the spherical center of the Luneberg lens are collinear. The sliding parts 30 of the left sliding block 10 and the right sliding block 20 also have an arc-shaped strip structure. One end of the connecting base 40 is fixedly connected to the movable base 50, and the other end of the connecting base 40 is formed with a long thrust hole 401, the length of which is perpendicular to the axis of screw 8. LR / Rnn / eznz / e / Yi 60. A movable hole 701 is formed in the reflective plate 70 for one end, formed by the long push hole 401 of the connecting base 40. A push rod 702 is also fixed to the reflective plate 70. The push rod 702 passes through the long push hole 401 of the connecting base 40, and the projections of the axis of the push rod 702 and the axis of the screw 60 on the mounting surface of the mounting plate are vertical to each other. In this embodiment, with this structural design, the feeder can be moved along the left guide rail 8 and the right guide rail 9 of the arc-shaped part to adjust its position, so that no matter where the feeder is adjusted, it can always point to the spherical center of the Luneberg lens, and thus the feeder receives and transmits signals more effectively. Embodiment 3 The difference between this embodiment and embodiment 2 is that the structures of the connecting bases are different. The connecting base in embodiment 2 is manufactured as a single piece. As shown in Figure 7, the connecting base 80 of this embodiment consists of a top-mounting base 90 and a bottom-mounting base 100. The bottom-mounting base 100 is fixed to the movable base, forming a downward-recessed portion 1001 with an upward-facing notch in the bottom-mounting base 100. The top-mounting base 90 is fixedly connected to the bottom-mounting base 100, forming an upward-recessed portion 901 with a downward-facing notch in the top-mounting base 90. The upward-recessed portion 901 is assembled with the downward-recessed portion 1001 to form the long push-through hole 200.In this embodiment, with the design of forming the long thrust hole 200 through this assembled structure, when the Luneberg lens antenna with the feed moving along an arc path needs to be changed to the Luneberg lens antenna with the feed moving along a straight path, it is only necessary to replace the reflector plate, guide rail, and sliding block described in embodiment 1 with the reflector plate, guide rail, and sliding block in embodiment 2, and remove the upper mounting base 90 so that the lower mounting base 100 connects the movable base to the reflector plate. In this way, the improvement speed can be greatly improved and the product development cost can be reduced even further.

During operation, the motor 3001 of the first Luneberg lens antenna 300 drives its screw 3002 to rotate, causing a movable base 3003 of the first Luneberg lens antenna 300 to move along the screw 3002, so that the connecting base 500, which is fixed together with the movable base 3003 on the first Luneberg lens antenna 300, and the connecting base 500 of the second Luneberg lens antenna 400 operate simultaneously.The 500 connection bases of the first Luneberg lens antenna 300 and the second Luneberg lens antenna 400 are all connected with the 700 reflective plate. The 700 reflective plates of the first Luneberg lens antenna 300 and the second Luneberg lens antenna 400 are all provided with an 800 feeder, so that the feeder positions of a plurality of Luneberg lens antennas can be adjusted in a latching mode, which is highly operationally efficient and convenient to use.

The first Luneberg lens antenna 900 is a Luneberg lens antenna structure with the electrically adjustable position feed described in embodiment 2, after the housing has been removed. The difference between each of the second Luneberg lens antennas 1000 and the first Luneberg lens antenna 900 is that there is no motor or screw in the 10 LR / Rnn / eznz / e / Yi second Luneberg lens antenna 1000 and, consequently, there are no related components, such as a guide rod, connected with the motor and screw in the second Luneberg lens antenna 1000 in relation to the first Luneberg lens antenna 900. A screw 9002 of the first Luneberg lens antenna 900 is also in threaded connection with a threaded hole of a movable base 2000 of each of the second Luneberg lens antennas 1000, and a guide hole in the movable base 2000 of the second Luneberg lens antenna 1000 is sleeved in a guide rod of the first Luneberg lens antenna 900. In implementation, the first Luneberg 900 lens antenna and each of the second Luneberg 1000 lens antennas can share a mounting plate for mounting the guide rail.In the implementation, the motor 9001 of the first Luneberg lens antenna 900 drives its screw 9002 to rotate, allowing the movable base 2000 of the first Luneberg lens antenna 900 and the movable base 2000 of each of the second Luneberg lens antennas 1000 to move along the screw 9002.
