Description

Technical Field

[0001] The present disclosure relates to the field of antennas, and in particular to a Cassegrain antenna module and a CPE communication device. Background Art

[0002] The CPE (Customer Premise Equipment) antenna is a new signal relay device that has emerged in recent years. It receives signals from mobile communication base stations, relays the mobile communication signals for a second time, and then forwards them in the form of Wi-Fi signals, supporting the connection of multiple Wi-Fi devices. The existing CPE antenna equipment can amplify and forward signals from mobile communication base stations, but the signals cannot be amplified infinitely. At longer distances, the signals will attenuate and normal communication functions cannot be achieved. In particular, long-distance signal transmission in a specific direction is required, and CPE signals alone can no longer meet usage requirements. In order to improve the signal strength (gain) at longer distances, especially signal transmission in a specific direction, an external Cassegrain antenna can be added to the CPE. The Cassegrain antenna can effectively improve the signal gain in that direction.

[0003] However, in the prior art, most Cassegrain antennas supporting CPE are installed in an exposed manner, such as the Cassegrain antenna disclosed in application number CN202120619535.2. The exposed installation easily causes the antenna to age and corrode quickly. In addition, the Cassegrain antennas in the prior art are mostly machined or die-cast, which has a high cost. On the other hand, the Cassegrain antennas supporting the existing CPE are more complicated to install, the fixed structure is bulky, and there are structures such as threaded columns on the CPE shell. However, when the user does not need to install the Cassegrain antenna, the raised threaded columns on the CPE shell will seriously affect the appearance of the product.

[0004] Therefore, there is an urgent need for a Cassegrain antenna module that can increase service life, reduce production costs, have a simple installation structure, and a modular design. Summary of the invention

The solution proposed in the present invention only requires injection molding, and the main and auxiliary reflectors can be produced using sheet metal stamping and spinning processes, which greatly reduces the mold cost and is suitable for mass production.

[0039] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0040] like Figures 1 to 3 As shown, a Cassegrain antenna module 10 of an embodiment includes a CPE antenna cover 100, a feed source 200 and a Cassegrain antenna assembly 300, wherein the feed source 200 is installed in the CPE antenna cover 100, and the Cassegrain antenna assembly 300 includes a Cassegrain antenna cover 310, a main reflector 320, a secondary reflector 330 and a bottom plate 340, wherein the bottom plate 340 is connected to the Cassegrain antenna cover 310, and the Cassegrain antenna cover 310 is connected to the bottom plate 340. 40 together form a receiving cavity 300a, the main reflector 320 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310, the sub-reflector 330 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310, the feed source 200, the main reflector 320 and the sub-reflector 330 are arranged in sequence so that the signal of the feed source 200 passes through the main reflector 320 and the sub-reflector 330 in turn.

[0041] Furthermore, a side of the base plate 340 facing away from the Cassegrain antenna cover 310 is provided with a hanging buckle 311 and a fastener 312, the CPE antenna cover 100 is provided with a hanging groove 110, the hanging buckle 311 is at least partially located in the hanging groove 110, so that the base plate 340 can be hung on the CPE antenna cover 100, the CPE antenna cover 100 is provided with a connecting hole 120, and the fastener 312 passes through the connecting hole 120 to fix the base plate 340 to the CPE antenna cover 100.

[0042] In this embodiment, the feed source 200 is installed in the CPE antenna cover 100, the main reflector 320 and the sub-reflector 330 are both encapsulated in the Cassegrain antenna cover 310, and the CPE antenna cover 100 and the Cassegrain antenna cover 310 are detachably connected via the mounting structure on the base plate 340. The CPE antenna cover 100 only needs to have a hanging groove 110 and a connecting hole 120. Specifically, a side of the bottom plate 340 facing away from the Cassegrain antenna cover 310 is provided with a hook 311 and a fastener 312. The hook 311 is partially inserted into the hanging groove 110, so that the bottom plate 340 is mounted on the CPE antenna cover 100. The fastener 312 passes through the connecting hole 120, so that the bottom plate 340 and the CPE antenna cover 100 are fixed. In this way, the CPE antenna cover 100 and the Cassegrain antenna cover 310 are modularly designed, that is, the CPE antenna cover 100 and its internal parts can complete signal transmission independently. When it is necessary to add a Cassegrain antenna assembly 300 to enhance the signal, the bottom plate 340 and the CPE antenna cover 100 are spliced ​​to complete the assembly. Furthermore, the Cassegrain antenna module 10 is as follows: the main reflector 320 is provided with a signal conduction avoidance hole, and the signal of the feed source 200 is radiated to the working surface of the sub-reflector 330 through the signal conduction avoidance hole, and then the sub-reflector 330 reflects the signal to the working surface of the main reflector 320, and finally the signal is reflected in parallel through the working surface of the main reflector 320 to complete the signal transmission.

[0043] In the above-mentioned Cassegrain antenna module 10, the feed source 200 is installed in the CPE antenna cover 100, the main reflector 320 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310, and the sub-reflector 330 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310, that is, the main reflector 320 and the sub-reflector 330 are both installed in the Cassegrain antenna cover 310, so that the relative position of the main reflector 320 and the sub-reflector 330 is more accurate, ensuring stable product performance. At the same time, the CPE antenna cover 100 protects the feed source 200, and the Cassegrain antenna cover 310 protects the main reflector 320 and the sub-reflector 330. To improve the corrosion resistance and aging resistance of the Cassegrain antenna module 10, thereby increasing its service life; on the other hand, a side of the base plate 340 facing away from the Cassegrain antenna cover 310 is provided with a hook 311 and a fastener 312, and the CPE antenna cover 100 is provided with a hanging groove 110 and a connecting hole 120. Part of the structure of the hook 311 is located in the hanging groove 110, and the fastener 312 passes through the connecting hole 120. The base plate 340 and the CPE antenna cover 100 are fixed together by the hook 311 and the fastener 312, which is convenient for disassembly and assembly, and the mounting structure is integrated on the base plate 340, so that the structure of the CPE antenna cover 100 is simpler and more compact. Furthermore, the CPE antenna cover 100 and the Cassegrain antenna cover 310 are modularly designed. When the Cassegrain antenna assembly 300 is not needed, the surface of the CPE antenna cover 100 is not provided with structures such as threaded columns, thereby maintaining the overall beauty of the CPE antenna. Since traditional Cassegrain antenna processing requires die-casting molds and post-machining, the costs of die-casting molds and machining are very high. The solution proposed in the present invention only requires injection molding, and the main and auxiliary reflectors can be produced using sheet metal stamping and spinning processes, thereby greatly reducing mold costs and being suitable for mass production.

[0044] like Figure 4 As shown, in one embodiment, the fastener 312 includes a connecting portion 3121 and a screw 3122, the connecting portion 3121 is fixedly connected to the bottom plate 340, the connecting portion 3121 is provided with a screw hole corresponding to the connecting hole 120, and the screw 3122 sequentially passes through the screw hole and the connecting hole 120, so that the bottom plate 340 is screwed to the CPE antenna cover 100. In this embodiment, the bottom plate 340 and the connecting portion 3121 are integrally injection molded, the connecting portion 3121 is provided with a screw hole, the connecting hole 120 is a screw hole, and the screw 3122 sequentially passes through the screw hole and the connecting hole 120, so that the bottom plate 340 is screwed and fixed to the CPE antenna cover 100, so as to facilitate the disassembly of the bottom plate 340 and the CPE antenna cover 100.

In this embodiment, the fastener 312 is a buckle, and the buckle is convexly provided with a clamping column 3123. When the CPE antenna cover 100 is embedded in the buckle, the clamping column 3123 passes through the connecting hole 120, so that the bottom plate 340 is clamped with the CPE antenna cover 100, thereby making the bottom plate 340 and the CPE antenna cover 100 more convenient to disassemble and assemble.

[0046] In one embodiment, the bottom plate 340, the hook 311 and the fastener 312 are an integrally formed structure. In this embodiment, the bottom plate 340, the hook 311 and the fastener 312 are an integrally formed structure, and the bottom plate 340, the hook 311 and the fastener 312 are an integrally formed structure. By injection molding, the bottom plate 340, the hook 311 and the fastener 312 have a higher structural strength and a more compact structure.

In this embodiment, the hanging groove 110 is opened at the top of the CPE antenna cover 100, and the hanging buckle 311 of the bottom plate 340 is partially located in the hanging groove 110, so that the bottom plate 340 is hung in the hanging groove 110, but at this time, the connection between the bottom plate 340 and the CPE antenna cover 100 is not stable enough, by opening the connecting hole 120 in the CPE antenna cover 100, correspondingly, the fastener 312 is also located on the side of the CPE antenna cover 100, and the fastener 312 connects and fixes the CPE antenna cover 100 and the bottom plate 340, so that the connection stability between the CPE antenna cover 100 and the bottom plate 340 is higher.

[0048] like Figure 4 and Figure 5 As shown, in one embodiment, the number of the fasteners 312 is at least two, and the two fasteners 312 are respectively located on both sides of the CPE antenna cover 100. In this embodiment, the two fasteners 312 are symmetrically arranged relative to the CPE antenna cover 100, and the CPE antenna cover 100 is located between the two fasteners 312, so that the two fasteners 312 fix the two sides of the CPE antenna cover 100, so that the fixing effect of the CPE antenna cover 100 is better.

[0049] like Figure 2 and Figure 6As shown, in one embodiment, the Cassegrain antenna assembly 300 further includes a first screw connection member 350, the base plate 340 is provided with a first screw connection hole, the Cassegrain antenna cover 310 is provided with a second screw connection hole, and the first screw connection member 350 sequentially passes through the first screw connection hole and the second screw connection hole to screw the base plate 340 with the Cassegrain antenna cover 310. In this embodiment, the first screw connection member 350 is a screw, the Cassegrain antenna cover 310 is provided with a threaded column, the second screw connection hole is provided in the threaded column, and the screw sequentially passes through the first screw connection hole and the second screw connection hole to screw the base plate 340 with the Cassegrain antenna cover 310 to facilitate the disassembly and assembly of the base plate 340. Furthermore, in other embodiments, the base plate 340 can also be fixed to the Cassegrain antenna cover 310 by other methods such as snap-fit, hot melt, and adhesive.

[0050] like Figure 2 and Figure 6 As shown, in one embodiment, the Cassegrain antenna assembly 300 further includes a second screw connection member 360, the main reflector 320 is provided with a third screw connection hole, the Cassegrain antenna cover 310 is provided with a fourth screw connection hole, and the second screw connection member 360 sequentially passes through the third screw connection hole and the fourth screw connection hole, so that the main reflector 320 is screwed to the Cassegrain antenna cover 310. In this embodiment, the second screw connection member 360 is a screw, the Cassegrain antenna cover 310 is provided with a threaded column, the fourth screw connection hole is provided in the threaded column, and the screw sequentially passes through the third screw connection hole and the fourth screw connection hole, so that the main reflector 320 is screwed and fixed to the Cassegrain antenna cover 310, so as to facilitate the disassembly and assembly of the main reflector 320. Further, in other embodiments, the main reflector 320 can also be fixed to the Cassegrain antenna cover 310 by other methods such as snap-fit, hot melt, and adhesive.

[0051] like Figure 2 and Figure 6 As shown, in one embodiment, the Cassegrain antenna assembly 300 further includes a third screw member 370, the secondary reflector 330 is provided with a fifth screw hole, the Cassegrain antenna cover 310 is provided with a sixth screw hole, and the third screw member 370 sequentially passes through the fifth screw hole and the sixth screw hole, so that the secondary reflector 330 is screwed to the Cassegrain antenna cover 310. In this embodiment, the second screw member 360 is a screw, a threaded column is provided in the Cassegrain antenna cover 310, the sixth screw hole is provided in the threaded column, and the screw sequentially passes through the fifth screw hole and the sixth screw hole, so that the secondary reflector 330 is screwed and fixed to the Cassegrain antenna cover 310, so as to facilitate the disassembly and assembly of the secondary reflector 330. Further, in other embodiments, the secondary reflector 330 can also be fixed to the Cassegrain antenna cover 310 by other methods such as snap, hot melt, adhesive, etc.

[0052] It can be understood that the main reflector 320 and the sub-reflector 330 are both made of metal to reflect the signal, and the main reflector 320 is installed in the Cassegrain antenna cover 310 by screws, and the sub-reflector 330 is installed in the Cassegrain antenna cover 310 by screws. Although the weight is greatly reduced compared with the traditional machined or die-cast Cassegrain antenna, the screws and the main reflector 320 and the sub-reflector 330 made of metal still do not make the structure of the Cassegrain antenna assembly 300 extremely lightweight, and the operation of locking the screws increases the installation time. In order to reduce the structural weight of the Cassegrain antenna assembly 300 and improve the installation efficiency, as shown in FIG. Figure 7 As shown, in one embodiment, the main reflector 320 and the base plate 340 are an integrally formed structure, a metal parabola 321 is formed on a side of the main reflector 320 facing away from the base plate 340, the secondary reflector 330 and the Cassegrain antenna cover 310 are an integrally formed structure, a metal hyperboloid 331 is formed on a side of the secondary reflector 330 adjacent to the main reflector 320, and the metal hyperboloid 331 is arranged opposite to the metal parabola 321.

[0053] In this embodiment, the main reflector 320 and the base plate 340 are integrally formed by injection molding, and a metal parabola 321 is formed on the side of the main reflector 320 facing away from the base plate 340, and the metal parabola 321 is used to reflect signals. The secondary reflector 330 and the Cassegrain antenna cover 310 are integrally formed by injection molding, and a metal hyperboloid 331 is formed on the side of the secondary reflector 330 close to the main reflector 320, and the metal hyperboloid 331 is used to reflect signals, that is, the feed source 200 signal passes through the metal parabola 321 and is arranged on the metal hyperboloid 331, and the metal hyperboloid 331 reflects the signal to the metal parabola 321, and finally the metal parabola 321 reflects the signal in parallel. Specifically, by integrally molding a bottom plate 340 and a main reflector 320 made of plastic, integrally molding a sub-reflector 330 and a Cassegrain antenna cover 310 made of plastic, retaining a metal parabola 321 and a metal hyperboloid 331 for reflecting signals, the metal parabola 321 and the metal hyperboloid 331 can be molded by an LDS local metallization process or a PVD local metallization process, and compared with the main reflector 320 and the sub-reflector 330 made of all metal, the overall structural weight of the Cassegrain antenna assembly 300 is effectively reduced, and the step of fixing the main reflector 320 and the sub-reflector 330 with screws is also omitted, thereby improving the installation efficiency. Furthermore, the cost of two sheet metal stamping dies for the main reflector and the sub-reflector is also omitted, greatly reducing the production cost of the Cassegrain antenna module.

[0054] Furthermore, in order to adapt to CPE antenna covers 100 of different models and heights, such as Figure 8As shown, in one embodiment, a sliding assembly 341 is provided on a side of the base plate 340 facing away from the Cassegrain antenna cover 310, and the sliding assembly 341 includes a longitudinal guide rail 3411 and a transverse guide rail 3412, the longitudinal guide rail 3411 is connected to the base plate 340, the transverse guide rail 3412 is slidably arranged with the longitudinal guide rail 3411, and the buckle 311 is slidably arranged on the transverse guide rail 3412. In this embodiment, the sliding assembly 341 is a "cross" shaped guide rail, the longitudinal guide rail 3411 is connected to the bottom plate 340, the transverse guide rail 3412 is slidably connected to the longitudinal guide rail 3411, and the hook 311 is slidably connected to the transverse guide rail 3412. When the CPE antenna cover 100 of different models or heights is used, the vertical distance and transverse distance of the hook 311 are adjusted so that the hook 311 is mounted on the CPE antenna cover 100. Specifically, the transverse guide rail 3412 can move along the vertical direction of the longitudinal guide rail 3411, thereby driving the hook 311 to move along the vertical direction of the longitudinal guide rail 3411. The fastener 311 can also move horizontally along the transverse guide rail 3412 to move the fastener 311 and the hanging groove 110 of the CPE antenna cover 100, so that the fastener 311 can be accurately installed in the hanging groove 110 of the CPE antenna cover 100. After the fastener 311 is installed in the hanging groove 110, it is fixed to the CPE antenna cover 100 by the fastener 312, thereby completing the assembly of the CPE antenna cover 100 and the Cassegrain antenna assembly 300, thereby improving the adaptability of the Cassegrain antenna assembly 300.

[0055] Furthermore, when the Cassegrain antenna module 10 is installed in an outdoor base station to receive and send signals, due to the harsh outdoor environment, it often encounters extreme weather such as strong winds, heavy rains, typhoons, etc. When the wind strength is strong, the Cassegrain antenna cover 310 will shake and vibrate. At this time, the Cassegrain antenna cover 310 collides with the main reflector 320 inside. Long-term collision is likely to damage the main reflector 320, so that the function of the main reflector 320 is impaired. Therefore, in order to prevent damage to the main reflector 320, such as Fig. 9As shown, in one embodiment, a first embedding groove 310a is opened inside the Cassegrain antenna cover 310, and the periphery of the main reflector 320 is covered with a first buffer pad (not shown in the figure), and the main reflector 320 is embedded in the first embedding groove 310a so that the first buffer pad is in interference fit with the groove wall of the first embedding groove 310a. In this embodiment, the main reflector 320 is screwed to the Cassegrain antenna cover 310 by screws. However, when encountering extreme weather such as strong winds and typhoons, the edge of the main reflector 320 will collide with the Cassegrain antenna cover 310. By coating the edge of the main reflector 320 with a layer of a first buffer pad, the first buffer pad can be an elastic material such as silicone or rubber. The first buffer pad can be connected to the edge of the main reflector 320 by bonding, and the thickness and length of the first buffer pad are small to avoid the first buffer pad occupying a large area of ​​the main reflector 320, thereby affecting the reflection area of ​​the main reflector 320. After the main reflector 320 is embedded in the first embedding groove 310a, it is locked by screws. At this time, the groove wall of the first embedding groove 310a is in interference fit with the first buffer pad. In this way, when the Cassegrain antenna cover 310 shakes, the Cassegrain antenna cover 310 will not directly collide with the main reflector 320, thereby preventing the main reflector 320 from being damaged due to long-term collision.

[0056] like Fig. 9 As shown, in another embodiment, the Cassegrain antenna cover 310 is provided with a second embedding groove 310b, the periphery of the secondary reflector 330 is covered with a second buffer pad (not shown), and the secondary reflector 330 is embedded in the second embedding groove 310b so that the second buffer pad is in interference fit with the groove wall of the second embedding groove 310b. In this embodiment, the secondary reflector 330 is screwed to the Cassegrain antenna cover 310 by screws. However, when there is extreme weather such as heavy rain, strong wind, typhoon, etc., the edge of the secondary reflector 330 will collide with the Cassegrain antenna cover 310. By coating the edge of the secondary reflector 330 with a layer of second buffer pad, the second buffer pad can be an elastic material such as silicone or rubber, and the second buffer pad can be connected to the edge of the secondary reflector 330 by bonding. The thickness and length of the second buffer pad are small to avoid the second buffer pad occupying a large area of ​​the secondary reflector 330, thereby affecting the reflection area of ​​the secondary reflector 330. After the secondary reflector 330 is embedded in the second embedding groove 310b, it is locked by screws. At this time, the groove wall of the second embedding groove 310b is in interference fit with the second buffer pad. In this way, when the Cassegrain antenna cover 310 shakes, the Cassegrain antenna cover 310 will not directly collide with the secondary reflector 330, thereby preventing the secondary reflector 330 from being damaged due to long-term collision.

[0057] Furthermore, when the Cassegrain antenna module 10 is installed in an outdoor base station, it may encounter extreme weather conditions such as heavy rain or rainstorms. Since the bottom plate 340 and the Cassegrain antenna cover 310 are fixed by screw connection, that is, there is a gap between the bottom plate 340 and the Cassegrain antenna cover 310, rainwater can enter the receiving cavity 300a formed by the Cassegrain antenna cover 310 and the bottom plate 340 through the gap, and water droplets evaporate in the receiving cavity 300a to form water mist and water vapor. The water mist and water vapor will scatter or refract electromagnetic waves, thus affecting the signal receiving effect of the main reflector 320 and the secondary reflector 330. Therefore, in order to improve the waterproof performance in the receiving cavity 300a, such as Fig. 9 As shown, in one embodiment, the Cassegrain antenna assembly 300 further includes a sealing ring (not shown), the Cassegrain antenna cover 310 is provided with a receiving groove 310c, and the sealing ring is located in the receiving groove 310c so that the sealing ring is interference-fitted between the Cassegrain antenna cover 310 and the base plate 340. In this embodiment, before installing the base plate 340, the sealing ring is first placed in the receiving groove 310c, and then the base plate 340 and the Cassegrain antenna cover 310 are locked by screws. At this time, the sealing ring located in the receiving groove 310c is interference-fitted between the base plate 340 and the Cassegrain antenna cover 310, and the sealing ring is just located under the gap between the base plate 340 and the Cassegrain antenna cover 310, that is, the sealing ring fills the gap between the base plate 340 and the Cassegrain antenna cover 310, so that the sealing between the base plate 340 and the Cassegrain antenna cover 310 is better, and rainwater cannot enter the receiving cavity 300a, that is, water mist and water vapor cannot be formed in the receiving cavity 300a, thereby avoiding the formed water mist and water vapor from affecting signal transmission.

[0058] The present application also provides a CPE communication device, including the Cassegrain antenna module 10 described in any of the above embodiments. The Cassegrain antenna module 10 includes a CPE antenna cover 100, a feed source 200 and a Cassegrain antenna assembly 300, wherein the feed source 200 is installed in the CPE antenna cover 100, and the Cassegrain antenna assembly 300 includes a Cassegrain antenna cover 310, a main reflector 320, a secondary reflector 330 and a bottom plate 340, wherein the bottom plate 340 is connected to the Cassegrain antenna cover 310, and the Cassegrain antenna cover 310 and the bottom plate 340 together form a receiving cavity 300a, wherein the main reflector 320 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310, and the secondary reflector 330 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310. The feed source 200, the main reflector 320 and the secondary reflector 330 are arranged in sequence so that the signal of the feed source 200 passes through the main reflector 320 and the secondary reflector 330 in sequence; a side of the bottom plate 340 away from the Cassegrain antenna cover 310 is provided with a hanging buckle 311 and a fastener 312, the CPE antenna cover 100 is provided with a hanging groove 110, and the hanging buckle 311 is at least partially located in the hanging groove 110, so that the bottom plate 340 is mounted on the CPE antenna cover 100, and the CPE antenna cover 100 is provided with a connecting hole 120, and the fastener 312 passes through the connecting hole 120 to fix the bottom plate 340 to the CPE antenna cover 100.

[0059] Compared with the prior art, the present invention has at least the following advantages:

[0060] In the above-mentioned Cassegrain antenna module 10, the feed source 200 is installed in the CPE antenna cover 100, the main reflector 320 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310, and the sub-reflector 330 is located in the receiving cavity 300a and is connected to the Cassegrain antenna cover 310, that is, the main reflector 320 and the sub-reflector 330 are both installed in the Cassegrain antenna cover 310, so that the relative position of the main reflector 320 and the sub-reflector 330 is more accurate, ensuring stable product performance. At the same time, the CPE antenna cover 100 protects the feed source 200, and the Cassegrain antenna cover 310 protects the main reflector 320 and the sub-reflector 330. To improve the corrosion resistance and aging resistance of the Cassegrain antenna module 10, thereby increasing its service life; on the other hand, a side of the base plate 340 facing away from the Cassegrain antenna cover 310 is provided with a hook 311 and a fastener 312, and the CPE antenna cover 100 is provided with a hanging groove 110 and a connecting hole 120. Part of the structure of the hook 311 is located in the hanging groove 110, and the fastener 312 passes through the connecting hole 120. The base plate 340 and the CPE antenna cover 100 are fixed together by the hook 311 and the fastener 312, which is convenient for disassembly and assembly, and the mounting structure is integrated on the base plate 340, so that the structure of the CPE antenna cover 100 is simpler and more compact. Furthermore, the CPE antenna cover 100 and the Cassegrain antenna cover 310 are modularly designed. When the Cassegrain antenna assembly 300 is not needed, the surface of the CPE antenna cover 100 is not provided with structures such as threaded columns, thereby maintaining the overall beauty of the CPE antenna. Since traditional Cassegrain antenna processing requires die-casting molds and post-machining, the costs of die-casting molds and machining are very high. The solution proposed in the present invention only requires injection molding, and the main and auxiliary reflectors can be produced using sheet metal stamping and spinning processes, which greatly reduces the mold and manufacturing costs and is suitable for mass production.
