Description

Communication equipment Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication device. Background Art

[0002] Parabolic antenna is a high-gain antenna widely used in long-distance communication systems such as radar, satellite and mobile communications.

[0003] Currently, when a parabolic antenna is assembled with a communication device, the communication device needs to be connected to the antenna output port of the parabolic antenna via an external feeder. Furthermore, the parabolic antenna also needs a feeder connected between its own antenna feed source and the antenna output port.

[0004] Summary of the Invention

[0005] An embodiment of the present application provides a communication device.

[0006] In a first aspect, an embodiment of the present application provides a communication device, the communication device comprising:

[0007] The antenna includes a feed source and a circuit board, wherein the feed source includes a dipole unit, the dipole unit includes a first dipole and a second dipole, and the second dipole is formed on a board surface of the circuit board;

[0008] A communication device includes a circuit board, a first dipole formed on a surface of the circuit board; a first slot body is provided on the circuit board, at least a portion of the circuit board is passed through the first slot body and connected to the circuit board; the first dipole and the second dipole are both electrically connected to the circuit board.

[0009] The communication device of the present application is achieved by integrating the first dipole in the feed source of the antenna on the circuit board of the communication device, and the second dipole in the feed source is integrated on the circuit board. In this way, after the circuit board is assembled on the circuit board and connected to the circuit board, the first dipole and the second dipole can both be connected to the circuit board, thereby achieving conduction between the antenna and the communication device, and making the communication device have a high degree of integration. When the communication device of the present application is installed at the construction site, there is no need to connect the communication device to the antenna output port of the antenna through an external feeder, or to connect the feed source to the antenna output port of the antenna. This not only simplifies the assembly process of the antenna and the communication device and reduces the construction cost of the communication device during installation, but also avoids the attenuation of the signal when the communication device is transmitted between the first dipole and the second dipole of the communication device, thereby increasing the gain of the antenna and improving the signal quality of the communication device, thereby improving the coverage performance and coverage distance of the communication device, and facilitating long-distance wireless communication. In addition, the first dipole and the second dipole can form a dual-channel signal port of the antenna.

[0010] In some embodiments, the circuit board has a long side and a short side. When the circuit board is inserted into the first slot, the long side intersects with and is connected to the surface of the circuit board, and the short side is located to the side of the circuit board.

[0011] The second dipole is provided on a side of the circuit board adjacent to the long side, so that the second dipole can be electrically connected to the circuit board, thereby realizing the signal transmission and signal reception functions of the antenna at the second dipole.

[0012] In some embodiments, the feed source is an orthogonal dual-polarization dipole, the first dipole is a vertically polarized dipole in the orthogonal dual-polarization dipole, and the second dipole is a horizontally polarized dipole in the orthogonal dual-polarization dipole.

[0013] In this way, the antenna receives and transmits signals along the electric field direction of the first dipole and the electric field direction of the second dipole.

[0014] In some embodiments, the length of the first slot body is greater than the length of the short side, and the slot width of the first slot body is greater than the thickness of the circuit board, so as to achieve assembly of the circuit board on the circuit board;

[0015] The long side is arranged perpendicular to the board surface of the circuit board, and the short side is arranged parallel to the board surface of the circuit board, so that the second dipole can form an orthogonal dual-polarization dipole with the first dipole.

[0016] In some embodiments, the first dipole includes two first radiating arms, which are formed on two board surfaces of the circuit board in the thickness direction, so that one of the two first radiating arms is connected to the RF port of the circuit board, and the other of the two first radiating arms can be grounded on the circuit board. The two first radiating arms are distributed symmetrically on both sides of the first slot body.

[0017] In some embodiments, the second dipole includes two second radiation arms, and the two second radiation arms are formed on the same board surface of the circuit board, or the two second radiation arms are formed on two board surfaces of the circuit board in the thickness direction, so that one of the two second radiation arms can be connected to the RF port of the circuit board, and the other of the two second radiation arms can be grounded on the circuit board, which can make the setting position of the second radiation arm more diversified.

[0018] In some embodiments, the first radiating arm includes a fan-shaped microstrip, and the width of the fan-shaped microstrip gradually increases in the direction in which the two first radiating arms move away from each other to increase the bandwidth of the antenna at the first dipole; the direction in which the width of the fan-shaped microstrip is parallel to the short side.

[0019] In some embodiments, the two first radiating arms are centrally symmetrical with each other and are located on either side of the first slot; and / or the two second radiating arms are centrally symmetrical with each other and are located on either side of the circuit board. In this way, the first dipole and the second dipole are both centrally symmetrical with each other. When the circuit board is inserted into the first slot, the two second radiating arms can be located on either side of the first dipole, so that the dipole unit can form an orthogonal dual-polarization dipole.

[0020] In some embodiments, the feed source further includes a first transmission line and a second transmission line, and the two first radiating arms respectively correspond to one first transmission line; one of the two first radiating arms is connected to the RF port on the circuit board through the corresponding first transmission line, and the other is grounded through the corresponding first transmission line, so that the two first radiating arms radiate;

[0021] The two second radiation arms respectively correspond to a second transmission line; one of the two second radiation arms is connected to the radio frequency port through the corresponding second transmission line, and the other is grounded through the corresponding second transmission line, so that the second radiation arm radiates.

[0022] In some embodiments, the first transmission line and the second transmission line are both formed on a circuit board, so as to achieve fixation of the first transmission line and the second transmission line.

[0023] In some embodiments, the feed source further includes a balun structure, which is located on the circuit board and is connected to the radio frequency port;

[0024] The two first radiating arms are respectively connected to the balun structure through a first transmission line to form radiation, and at the same time, the first radiating arms can be connected to the radio frequency port through the balun structure. The two second radiating arms are respectively connected to the balun structure through a second transmission line to form radiation, and at the same time, the second radiating arms can be connected to the radio frequency port through the balun structure.

[0025] The balun structure is configured to achieve a 180° phase shift, so that the current directions in the two first radiation arms are in the same direction, and the current directions in the two second radiation arms are in the same direction.

[0026] In this way, one of the two first radiating arms radiates outward while also being grounded through the other of the two first radiating arms, thereby achieving both radiation and grounding of the first dipole. Furthermore, the balun structure enables the currents in the two first transmission lines to flow in opposite directions, preventing radiation.

[0027] In addition, since the two first radiating arms are formed on two surfaces of the circuit board, it is possible to prevent one of the two first transmission lines from being covered by the other on the same side of the circuit board, thereby ensuring normal radiation and grounding of the two first radiating arms.

[0028] In some embodiments, the balun structure includes a first microstrip balun and a second microstrip balun, wherein the first microstrip balun is located on a side of the circuit board where the RF port is provided, and the second microstrip balun is located on a side of the circuit board opposite to the first microstrip balun and is grounded;

[0029] One of the two first radiation arms is connected to the first microstrip balun through the corresponding first transmission line, and the other is connected to the second microstrip balun through the corresponding first transmission line, thereby achieving radiation and grounding of the first dipole;

[0030] One of the second radiation arms is connected to the first microstrip balun through the corresponding second transmission line, and the other is connected to the second microstrip balun through the corresponding second transmission line, thereby achieving radiation and grounding of the second dipole.

[0031] In some embodiments, when at least a portion of the circuit board is inserted into the first slot, the circuit board intersects with the circuit board and is connected through a plurality of connecting portions. The connecting portions are arranged on the same surface of the circuit board so that the circuit board can be fixed on the circuit board through the connecting portions while the connection between the circuit boards can be completed on the same surface of the circuit board without flipping the circuit board.

[0032] In some embodiments, the first slot is located in the middle area of ​​the circuit board. This can prevent the connection portion (such as the soldering portion) from falling off when the circuit board is squeezed on both sides of the first slot in the length direction, thereby enhancing the stability of the connection between the circuit board and the circuit board.

[0033] In some embodiments, the distance between the first slot and the top edge of the circuit board is greater than or equal to 3 mm and less than or equal to 10 mm, so as to further enhance the stability of the connection portion.

[0034] In some embodiments, the antenna includes a parabolic antenna, which also includes a first reflector. The reflecting surface of the first reflector is a parabola, and the circuit board is located in the reflecting area of ​​the reflecting surface, so that the communication device can be integrated into the antenna while the antenna has the high gain characteristics of the parabolic antenna.

[0035] In some embodiments, the first dipole and the second dipole are spaced apart on a line connecting the focus of the parabola and the center of the parabola, and the second dipole is located below the first dipole to avoid overlap between the first dipole and the second dipole and signal interference, thereby ensuring the performance of the antenna and the electrical performance of the communication device.

[0036] In some embodiments, the first dipole is located at the focus of the parabola to ensure that the setting position of the first dipole meets the setting requirements of the parabola antenna for the dipole.

[0037] In some embodiments, the distance between the first dipole and the second dipole on the connecting line is greater than or equal to one-ninth of the wavelength of the center frequency of the parabolic antenna, and less than or equal to one-sixth of the wavelength of the center frequency of the parabolic antenna. This effectively prevents signal interference between the first dipole and the second dipole while also preventing a reduction in the gain of the second dipole.

[0038] In some embodiments, the length of the first slot is parallel to a line connecting the short side of the circuit board, the circuit board is provided with a second slot on a side where the second dipole is provided, and the second dipole is provided adjacent to a notch of the second slot.

[0039] When the circuit board is passed through the first slot body, part of the circuit board is passed through the first slot body and is placed on the slot wall of the first slot body. The second slot body is located below the first slot body so that the second dipole is arranged below the first dipole along the connection interval between the focus and the center of the parabola.

[0040] In some embodiments, the communication device further includes a microstrip parasitic element, located on a side of the dipole element away from the communication device and configured to increase the gain of the second dipole. The provision of the microstrip parasitic element helps reduce the gain difference and angle fluctuation between the first and second dipole elements, thereby reducing engineering focus operation time and improving the installation efficiency of the communication device.

[0041] In some embodiments, the microstrip parasitic unit includes a first microstrip unit and a second microstrip unit, and the first microstrip unit and the second microstrip unit each include two microstrips;

[0042] The two microstrips in the first microstrip unit are symmetrically arranged on the circuit board, and the two microstrips in the second microstrip unit are symmetrically arranged on the circuit board;

[0043] When at least part of the circuit board is inserted into the first slot, the two microstrips in the first microstrip unit and the two microstrips in the second microstrip unit are connected to each other to form a microstrip parasitic unit, so as to reduce the gain difference between the first dipole and the second dipole through the microstrip parasitic unit.

[0044] In some embodiments, the distance between the microstrip in the microstrip parasitic unit and the second radiating arm is one-quarter wavelength of the center frequency of the parabolic antenna, to ensure that the microstrip parasitic unit has a greater gain enhancement effect on the second dipole than on the first dipole.

[0045] In some embodiments, the antenna further includes a second reflector mounted on an end of the circuit board away from the first reflector, the second reflector covering the dipole unit. This allows the second reflector to re-reflect the signal reflected by the first reflector, further increasing the gain of the dipole unit at the first and second dipoles.

[0046] In some embodiments, the communication device further includes a housing, and the circuit board is located inside the housing to prevent the circuit board, the circuit board, and the second reflector from being exposed on the surface of the communication device; and / or,

[0047] The first reflector is provided with a plurality of through holes, which are distributed on the reflecting surface of the first reflector to improve the wind resistance level and aesthetics of the antenna.

[0048] In some embodiments, the parabolic antenna further includes a mounting base and a clamp, wherein the mounting base is mounted on a side of the first reflector away from the feed source;

[0049] The mounting base has two intersecting recessed portions, the shapes of which are adapted to the shape of the circumferential outer wall of the fixing rod. The ends of the recessed portions in the longitudinal direction extend to the side wall of the mounting base, and notches are formed on the side wall of the mounting base. The longitudinal direction of the recessed portions is parallel to the longitudinal direction of the fixing rod to be fixed, so that when the mounting base of the parabolic antenna is fixed to the fixing rod, the fixing rod can fix the recessed portions, and the mounting base can be limited by the recessed portions when being assembled on the fixing rod.

[0050] The clamp is removably attached to the mounting base, and can be positioned in either of the two recesses to secure the mounting base to the pole. By changing the clamp's position on the two mounting bases, the parabolic antenna can be fixed to either the horizontal or vertical rod of the pole, allowing the communication device to adapt to different installation locations.

[0051] In some embodiments, the parabolic antenna further includes a connecting base, which is mounted on the first reflector and located between the first reflector and the mounting base; the connecting base has a connecting axis;

[0052] The mounting seat is provided with a sleeve portion, which is sleeved on the circumferential outer side of the connecting shaft and connected to the connecting shaft; the connecting shaft is rotatably arranged relative to the sleeve portion.

[0053] By rotating the connecting shaft relative to the sleeve portion, the angle of the connecting seat relative to the mounting seat can be adjusted, thereby adjusting the horizontal installation angle of the communication device during installation, so as to facilitate the focusing of the communication equipment during construction.

[0054] In some embodiments, the first reflector has a fixing seat, the connecting seat has a connecting arm, and the connecting arm is arranged on the side of the fixing seat and is rotatably connected to the fixing seat.

[0055] By rotating the fixing base relative to the connecting arm, the pitch angle of the communication equipment during installation can be adjusted to facilitate focusing of the communication equipment during construction.

[0056] In a second aspect, an embodiment of the present application further provides a communication device, comprising a parabolic antenna, the parabolic antenna comprising a feed, a first reflector, a mounting base, and a clamp, wherein the reflecting surface of the first reflector is a parabola, and the feed is located within a reflecting area of ​​the reflecting surface of the first reflector; the mounting base is mounted on a side of the first reflector away from the feed source; the mounting base has a first recessed portion and a second recessed portion intersecting with each other, the shapes of the first recessed portion and the second recessed portion both being adapted to the shape of a circumferential outer wall of a fixing rod, and ends of the recessed portions extending axially along the fixing rod; the clamp is detachably mounted on the mounting base, and the clamp can be selectively positioned at either the first recessed portion or the second recessed portion to secure the mounting base to the fixing rod;

[0057] The ends of the first recessed portion and the second recessed portion in the length direction both extend to the side wall of the mounting seat and form a notch on the side wall of the mounting seat. The length directions of the first recessed portion and the second recessed portion are parallel to the length direction of the fixed rod.

[0058] The communication device of the present application can secure the parabolic antenna to either the horizontal or vertical rod of a fixed rod by changing the position of the clamp on the two mounting bases, thereby adapting the communication device to different installation sites. Furthermore, by providing the first and second recessed portions, the mounting base of the parabolic antenna is secured to the fixed rod while the fixed rod can be secured to either the first or second recessed portion, thereby limiting the assembly of the mounting base on the fixed rod.

[0059] In some embodiments, the first recess and the second recess are vertically arranged on the mounting seat, and the two hoops can be spaced apart along the extension direction of the recess, so that both hoops are encircled on the horizontal bar or the vertical bar, and the horizontal bar or the vertical bar in the fixing rod can be fixed in one of the first recess and the second recess.

[0060] In some embodiments, the mounting seat may have a through hole, and the clamp may be inserted into the through hole to achieve a detachable connection between the clamp and the mounting seat.

[0061] In some embodiments, the parabolic antenna further includes a connecting base, which is mounted on the first reflector and located between the first reflector and the mounting base; the connecting base has a connecting axis;

[0062] The mounting seat is provided with a sleeve portion, which is sleeved on the circumferential outer side of the connecting shaft and connected to the connecting shaft; the connecting shaft is rotatably arranged relative to the sleeve portion.

[0063] By rotating the connecting shaft relative to the sleeve portion, the angle of the connecting seat relative to the mounting seat can be adjusted, thereby adjusting the horizontal installation angle of the communication device during installation, so as to facilitate the focusing of the communication equipment during construction.

[0064] In some embodiments, the connecting seat is further equipped with a first connecting member. The connecting shaft has a first connecting hole. The first connecting member can be inserted into the first connecting hole and fixed to the sleeve portion to achieve connection between the sleeve portion and the connecting shaft.

[0065] In some embodiments, the connecting base is further provided with a first knob, the first knob being located on a side of the connecting base away from the mounting base. The first knob has a second connecting hole therein. The first connecting member can be sequentially inserted into the second connecting hole and the first connecting hole and fixed to the sleeve portion.

[0066] The horizontal installation angle of the communication device can be adjusted by the first knob.

[0067] In some embodiments, the connecting base has meshing teeth on a surface on which the connecting shaft is disposed, and the sleeve portion also has meshing teeth on a surface facing the connecting base. When the connecting shaft is assembled within the sleeve portion, the meshing teeth on the connecting base and the meshing teeth on the sleeve portion mesh with each other, thereby increasing the friction between the connecting base and the sleeve portion in the direction of rotation of the connecting shaft when the connecting base rotates relative to the sleeve portion, thereby ensuring that the angle of the connecting base relative to the sleeve portion remains constant.

[0068] In some embodiments, the first reflector has a fixing seat, the connecting seat has a connecting arm, and the connecting arm is arranged on the side of the fixing seat and is rotatably connected to the fixing seat.

[0069] By rotating the fixing base relative to the connecting arm, the pitch angle of the communication equipment during installation can be adjusted to facilitate focusing of the communication equipment during construction.

[0070] In some embodiments, there are two connecting arms, which are located on opposite sides of the fixing base and are both rotatably connected to the fixing base.

[0071] The provision of the two connecting arms can enhance the stability of the connection between the connecting seat and the fixing seat, and can also enhance the stability of the fixing seat when rotating relative to the connecting arms.

[0072] In some embodiments, the fixing base is further equipped with a second connecting member. The connecting arm has a fourth connecting hole. The fourth connecting hole is an arc-shaped hole. The fixing base has a fifth connecting hole.

[0073] In some embodiments, the parabolic antenna further includes a second knob. The second knob is located on a side of the connecting base away from the fixing base. The second knob defines a sixth connecting hole. The second connector can be inserted into the sixth connecting hole, the fifth connecting hole, and the two fourth connecting holes and fixed to the connecting arm.

[0074] The pitch angle of the communication equipment during installation can be adjusted by rotating the second knob to facilitate focusing of the communication equipment during construction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0100] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0101] The terms used in the implementation section of this application are only used to explain the specific embodiments of the application and are not intended to limit the application.

[0102] To facilitate understanding, the relevant technical terms involved in the embodiments of this application are first explained and illustrated.

[0103] A parabolic antenna consists of a parabolic reflector and a feed located at its focal point, F. A parabolic reflector is a reflector with a parabolic reflective surface. As shown in Figure 1, during transmission, the signal radiates from the feed toward the parabolic surface of the reflector, where it is reflected and then radiates into the air. Because the feed is located at the parabola's focal point, F, the electromagnetic wave, after reflection from the parabola, radiates parallel to the parabola's normal. During reception, after reflection from the reflector, the electromagnetic wave converges onto the feed, allowing the feed to receive maximum signal energy.

[0104] Gain is the ratio of the signal strength produced by an actual antenna to that of an ideal, non-directional point source at the same point in space, under conditions of equal input power. Antenna gain measures an antenna's ability to transmit and receive signals in a specific direction and is a key parameter for selecting base station antennas. Gain is closely related to antenna directivity. The higher the antenna gain, the narrower the main lobe on the antenna's radiation pattern, resulting in better directivity and more concentrated energy.

[0105] There are usually two or more lobes in the antenna's radiation pattern, among which the lobe with the greatest radiation intensity is called the main lobe, and the remaining lobes are called side lobes.

[0106] The focal length to aperture ratio of an antenna is also called the focal diameter ratio. As shown in Figure 2, the focal length to aperture ratio of an antenna can be expressed as f / d. Taking a parabolic antenna as an example, f refers to the focal length of the parabola, and d is the aperture diameter of the parabola projected onto a plane perpendicular to the axis.

[0107] Parabolic antennas are capable of forming high-gain and highly directional beams, giving them the characteristics of high gain and strong directivity. Parabolic antennas offer multiple advantages in communication systems. First, their high gain allows them to provide stronger signals and longer transmission distances. Second, their beam-focusing properties reduce the effects of multipath interference and background noise, thereby improving communication quality and reliability. Therefore, parabolic antennas are ideal for long-distance wireless communication systems and are widely used in remote communication systems such as radar, satellite, and mobile communications. For example, the transmission distance in long-distance wireless communication systems can be greater than or equal to 8 kilometers and less than or equal to 15 kilometers.

[0108] Currently, when assembling the feed source of a conventional parabolic antenna and a communication device, the communication device must be connected to the antenna output port of the parabolic antenna via an external feeder, and the conventional parabolic antenna also requires an external feeder connection between the feed source and the antenna output port. The communication device may include a bridge device. The bridge device may include wireless network equipment such as micro base stations, Wi-Fi bridges, Ethernet bridges, and bridge routers. Due to the connection of the two external feeders mentioned above, during construction, not only is the communication device connected to the parabolic antenna at the antenna output port, but the feed source and antenna output port also connected. This makes assembly of the parabolic antenna and communication device more complicated and increases the construction cost of assembling the parabolic antenna and communication device.

[0109] The presence of the two external feeders mentioned above increases signal loss during transmission between the communication device and the parabolic antenna. Furthermore, the external feeder between the feed source and the antenna output affects the gain and radiation pattern of the parabolic antenna, increasing the difficulty of parabolic antenna design and development.

[0110] A parabolic antenna is provided in the related art. The parabolic antenna has multiple feed sources, which are combined by a combiner. This makes the structure of the feed sources and the fixing structure on the reflector of the parabolic antenna relatively complicated.

[0111] In view of this, an embodiment of the present application provides a communication device that can solve the technical problems of the traditional parabolic antenna mentioned above.

[0112] The structure of the communication device is further described below with reference to the accompanying drawings and embodiments.

[0113] As shown in FIG3 , a communication device includes an antenna. The antenna includes a feed source 100 and a circuit board 200. Feed source 100 includes a dipole unit, which includes a first dipole 110 and a second dipole 120. Second dipole 120 is formed on one side of circuit board 200, that is, second dipole 120 is integrated onto the surface of circuit board 200. For example, second dipole 120 can be formed on the surface of circuit board 200 by printing or other methods.

[0114] The communication device also includes a communication device. The communication device may be a network bridge device. The types of network bridge devices are described above and are not further described here. The communication device may include a circuit board 300. The circuit board 300 is a printed circuit board that carries a large number of electronic components within the communication device. The circuit board 300 not only controls the transmission of signals such as current and voltage within the communication device to ensure stable operation of the communication device, but also provides protection and detection functions to protect the communication device from electrical or electromagnetic interference. For example, the protection and detection functions provided by the circuit board 300 may include overcurrent, overvoltage, and short-circuit protection. The circuit board 300 is a conventional structure within a communication device, and its structure is not further described here. The first dipole 110 is formed on the surface of the circuit board 300. In other words, the first dipole 110 is integrated onto one side of the circuit board 300. For example, the first dipole 110 may be formed onto one side of the circuit board 300 by printing or other methods.

[0115] The first dipole 110 can be directly integrated onto the surface of the circuit board 300. Alternatively, when the available space on the circuit board 300 is limited, the surface size of the circuit board can be extended to ensure sufficient space on the surface of the circuit board 300 to integrate the first dipole 110. Figures 4 and 5 respectively illustrate schematic diagrams of the assembly of the circuit board 200 and the circuit board 300 from different perspectives. As shown in Figures 4 and 5, a first slot 310 is provided on the circuit board 300. At least a portion of the circuit board 200 is inserted into the first slot 310 and connected to the circuit board 300 to achieve assembly and fixation of the circuit board 200 on the circuit board 300. For example, the circuit board 200 can be connected to the circuit board 300 by welding or other methods. The first dipole 110 and the second dipole 120 are both electrically connected to the circuit board 300 to facilitate electrical connection between the antenna and the communication device, thereby achieving the signal transmission and signal reception functions of the antenna at the first dipole 110 and the second dipole 120, respectively. The first dipole 110 and the second dipole 120 may form a dual-channel signal port of the antenna. That is, the first dipole 110 forms one of the dual-channel signal ports, and the second dipole 120 forms the other of the dual-channel signal ports.

[0116] An extension portion 340 is provided on the circuit board 300, and the first groove body 310 can be opened in the extension portion 340 so as to realize the assembly and fixation of the circuit board 200 on the circuit board 300 while avoiding the opening of the first groove body 310 affecting the area of ​​​​the layout of electronic devices on the circuit board 300.

[0117] The following takes the first dipole 110 as an example to further illustrate the signal transmission and signal reception functions of the antenna at one of its signal ports.

[0118] The communication device can provide a signal (such as a current signal) to the first dipole 110, so that when the signal is transmitted within the first dipole 110, it can form an electromagnetic wave, so that the electromagnetic wave can be radiated outward along the antenna, thereby realizing the signal transmission function of the antenna at the first dipole 110. Alternatively, the first dipole 110 can also receive a signal (such as an electromagnetic wave signal) and transmit the received signal to the communication device, thereby realizing the signal reception function of the antenna at the first dipole 110.

[0119] The signal transmission and signal reception function processes of the antenna at the signal port of the second dipole 120 can be referred to the relevant description of the first dipole 110 and will not be repeated here.

[0120] In the communication device, the first dipole 110 of the antenna feed 100 is integrated on the circuit board 300, and the second dipole 120 of the feed 100 is integrated on the circuit board 200. Thus, after the circuit board 200 is assembled on and connected to the circuit board 300, both the first dipole 110 and the second dipole 120 can be electrically connected to the circuit board 300, achieving electrical connection between the antenna and the communication device while also providing a high level of integration for the communication device.

[0121] The connection between the circuit board 200 and the circuit board 300 can be connected during the production process of the communication equipment to achieve conduction between the antenna and the communication device. When the communication equipment of the present application is constructed and installed at the construction site, there is no need for the communication device to be connected to the antenna output port of the antenna through an external feeder, or to connect the feed source 100 to the antenna output port of the antenna. Therefore, when the communication equipment of the present application is fixed on the construction site, the internal antenna can be fixed on the construction site. Compared with the traditional parabolic antenna, the communication equipment of the present application can simplify the assembly process of the antenna and the communication device, and reduce the construction cost of the communication equipment during installation. The antenna of the present application also does not need to be provided with an antenna output port, which can simplify the structure of the antenna.

[0122] Furthermore, since no external feeder connection is required, signal attenuation can be avoided when the communication device is transmitted between the first dipole 110 and the second dipole 120, thereby increasing the gain of the antenna and improving the signal quality of the communication device, thereby improving the coverage performance and coverage distance of the communication device, and facilitating long-distance wireless communication.

[0123] The feed source 100 can be fixed on the antenna through the circuit board 300 and the circuit board 200. At the same time, there is no need to set a feed source 100 fixing structure such as a combiner in the feed source 100, which can simplify the structure of the feed source 100 and the fixation on the antenna.

[0124] As shown in Figure 5, circuit board 200 has a long side 210 and a short side 220. When circuit board 200 is placed in first slot 310, long side 210 intersects and connects to the surface of circuit board 300, while short side 220 is located to the side of circuit board 300. Second dipole 120 is positioned on circuit board 200 adjacent to long side 210 to ensure electrical connection between second dipole 120 and circuit board 300, enabling the antenna's signal transmission and reception functions at second dipole 120.

[0125] In some embodiments, the dipole unit may be an orthogonal dual-polarized dipole. The first dipole 110 is a vertically polarized dipole in the orthogonal dual-polarized dipole. The second dipole 120 is a horizontally polarized dipole in the orthogonal dual-polarized dipole. In this way, the antenna can transmit and receive signals at the first dipole 110 along the direction of the electric field of the first dipole 110. The antenna can also transmit and receive signals at the second dipole 120 along the direction of the electric field of the second dipole 120. This enables the antenna to transmit and receive signals in multiple directions.

[0126] The electric field directions of a vertically polarized dipole and a horizontally polarized dipole are perpendicular to each other. For communications equipment, a vertically polarized dipole can be understood as a dipole whose electric field direction is perpendicular to the ground when the communications equipment is installed at the installation site, and a horizontally polarized dipole can be understood as a dipole whose electric field direction is parallel to the ground when the communications equipment is installed at the installation site.

[0127] In the present application, the first dipole 110 is a vertically polarized dipole, and the electric field direction of the first dipole 110 can be seen in the Y direction in Figure 5. The second dipole 120 is a horizontally polarized dipole, and the electric field direction can be seen in the X direction in Figure 5. It should be noted that when the communication equipment is installed at the installation site, the electric field directions of the first dipole 110 and the second dipole 120 may change relative to the ground when the pitch angle of the communication equipment is adjusted.

[0128] As shown in Figure 5, the length of the first groove body 310 is greater than the length of the short side 220, and the groove width of the first groove body 310 is greater than the thickness of the circuit board 200, so that the circuit board 200 can be inserted into the first groove body 310 to realize the assembly of the circuit board 200 on the circuit board 300.

[0129] The long side 210 can be arranged perpendicular to the surface of the circuit board 300, and the short side 220 can be arranged parallel to the surface of the circuit board 300. In this case, the circuit board 200 is arranged perpendicular to the circuit board 300 so that the second dipole 120 can form an orthogonal dual-polarization dipole with the first dipole 110.

[0130] Figures 6 and 7 illustrate schematic diagrams of the assembly of a circuit board 200 and a circuit board 300 from different perspectives. Figures 6 and 7 show two sides of the circuit board 300 in the thickness direction. Figure 6 shows the front side of the balun structure 130 on the circuit board 300. Figure 7 shows the back side of the balun structure 130 on the circuit board 300. In other words, the balun structure 130 is formed on both sides of the circuit board 300 in the thickness direction.

[0131] 6 and 7 , the first dipole 110 includes two first radiating arms 111. The two first radiating arms 111 can be formed on two surfaces of the circuit board 300 in the thickness direction, such that one of the two first radiating arms 111 is electrically connected to the RF port 320 of the circuit board 300, and the other of the two first radiating arms 111 can be grounded on the circuit board 300.

[0132] 4 and 5 , the second dipole 120 includes two second radiating arms 121, which can be formed on the same surface of the circuit board 200. Thus, one of the two second radiating arms 121 can be electrically connected to the RF port 320 of the circuit board 300, and the other of the two second radiating arms 121 can be grounded on the circuit board 300.

[0133] In some embodiments, the two second radiating arms 121 may also be formed on two surfaces of the circuit board 200 in the thickness direction. Similarly, one of the two second radiating arms 121 can be electrically connected to the RF port 320 of the circuit board 300, while the other of the two second radiating arms 121 is grounded on the circuit board 300.

[0134] The structure of the communication device will be further described below by taking the example that the two second radiating arms 121 can be formed on the same board surface of the circuit board 200 .

[0135] As shown in Figures 6 and 7 , the two first radiating arms 111 are centrally symmetrical structures. Furthermore, the two first radiating arms 111 are located on either side of the first slot 310 so that the two first radiating arms 111 can form a first dipole 110. As shown in Figures 4 and 5 , the two second radiating arms 121 are centrally symmetrical structures. The two second radiating arms are located on either side of the circuit board 200 so that the two second radiating arms 121 can form a second dipole 120. In this way, the first dipole 110 can have a centrally symmetrical structure. The second dipole 120 can also have a centrally symmetrical structure. The antenna can include a parabolic antenna. When the antenna is a parabolic antenna, the phase center of the feed source 100 (e.g., the first dipole or the second dipole) can be located at the focus of the parabola of the parabola to increase the antenna gain and thus the transmission distance of the communication device. The phase center of the first dipole can be considered the center of symmetry of the first dipole. The phase center of the second dipole can be considered the center of symmetry of the second dipole.

[0136] Furthermore, since the two first radiating arms 111 are centrally symmetrically distributed on both sides of the first slot 310 , when the circuit board 200 is inserted into the first slot 310 , the two second radiating arms 121 can be distributed on both sides of the first dipole 110 , so that the dipole unit can form an orthogonal dual-polarization dipole.

[0137] As shown in FIG4 , first radiating arm 111 may include, but is not limited to, a fan-shaped microstrip. For example, first radiating arm 111 may also include a rectangular microstrip. When first radiating arm 111 is a fan-shaped microstrip, the width of the fan-shaped microstrip may gradually increase as the two first radiating arms 111 move away from each other, thereby increasing the bandwidth of the antenna at first dipole 110. The width of the fan-shaped microstrip is parallel to the short side 220.

[0138] Accordingly, the second radiating arm 121 may include a rectangular or other shaped microstrip 530. In the present application, the shapes of the first radiating arm 111 and the second radiating arm 121 are not particularly limited.

[0139] The lengths of first radiating arm 111 and second radiating arm 121 may be greater than or equal to one-fifth of the wavelength of the center frequency of the parabolic antenna and less than or equal to one-third of the wavelength of the center frequency of the parabolic antenna. The lengths of first radiating arm 111 and second radiating arm 121 may be the same or different. When the lengths of first radiating arm 111 and second radiating arm 121 may be the same, illustratively, the lengths of first radiating arm 111 and second radiating arm 121 may each be one-quarter of the wavelength of the center frequency of the parabolic antenna.

[0140] Figures 6 and 7 illustrate schematic diagrams of the assembly of a circuit board 200 and a circuit board 300 from different perspectives. Figures 6 and 7 show two sides of the circuit board 300 in the thickness direction. Figure 6 shows the front side of the balun structure 130 on the circuit board 300. Figure 7 shows the back side of the balun structure 130 on the circuit board 300. In other words, the balun structure 130 is formed on both sides of the circuit board 300 in the thickness direction.

[0141] Referring to FIG. 6 and FIG. 7 , in some embodiments, the feed source 100 further includes a first transmission line 140 and a second transmission line 150. The two first radiating arms 111 each correspond to a first transmission line 140; one of the two first radiating arms 111 is electrically connected to the RF port 320 on the circuit board 300 via the corresponding first transmission line 140, while the other is grounded via the corresponding first transmission line 140, so that the two first radiating arms 111 radiate.

[0142] The two second radiating arms 121 each correspond to a second transmission line 150. One of the two second radiating arms 121 is connected to the RF port 320 via the corresponding second transmission line 150, and the other is grounded via the corresponding second transmission line 150, so that the second radiating arm 121 radiates.

[0143] The first transmission line 140 and the second transmission line 150 are both formed on the circuit board 300 to facilitate securing the first transmission line 140 and the second transmission line 150. In the embodiment of the present application, there are two first transmission lines 140. The two first transmission lines 140 are formed on two surfaces of the circuit board 300 in the thickness direction, so that each of the two first radiating arms 111 corresponds to a first transmission line 140 and is electrically connected to or grounded to the RF port 320 through the corresponding first transmission line 140.

[0144] In the embodiment of the present application, there are two second transmission lines 150. The two second transmission lines 150 are also formed on two surfaces of the circuit board 300 in the thickness direction, so that the two second radiating arms 121 each correspond to a second transmission line 150 and are respectively connected to the RF port 320 or grounded through the corresponding second transmission line 150.

[0145] Referring to FIG. 6 and FIG. 7 , in some embodiments, the feed source 100 further includes a balun structure 130. The balun structure 130 is located on the circuit board 300 and is electrically connected to the RF port 320 on the circuit board 300. The two first radiating arms 111 are electrically connected to the balun structure 130 via a first transmission line 140, respectively, to generate radiation. Furthermore, the balun structure 130 enables electrical connection between one of the first radiating arms 111 and the RF port 320.

[0146] The two second radiation arms 121 are respectively connected to the balun structure 130 via a second transmission line 150 to generate radiation. At the same time, the balun structure 130 can realize the connection between one second radiation arm 121 and the RF port 320 .

[0147] 6 and FIG7 , the balun structure 130 (not shown) is configured to achieve 180° phase shift, thereby aligning the currents in the two first radiating arms 111 and the currents in the two second radiating arms 121. The current directions in the first radiating arms 111 are indicated by dashed arrows in FIG6 for easier understanding.

[0148] The RF port 320 can be understood as an RF output port that provides a signal source to the first dipole 110 and the second dipole 120 through the balun structure 130. Accordingly, when the first dipole 110 and the second dipole 120 receive a signal, the RF port 320 can also be used to receive the signal on the first dipole 110 and the second dipole 120.

[0149] Because the balun structure 130 is configured to achieve 180° phase shift, when the RF port 320 on the circuit board 300 transmits a signal to the two first transmission lines 140 via the balun structure 130, the currents in the two first transmission lines 140 are in opposite directions, resulting in no radiation, and the currents in the two first radiating arms 111 are in the same direction. The current directions of the first transmission lines 140 are also indicated by dashed arrows in FIG6 for easier understanding. This allows one of the two first radiating arms 111 to radiate outward while also being grounded via the other of the two first radiating arms 111, thereby achieving both radiation and grounding for the first dipole 110.

[0150] The two first transmission lines 140 corresponding to the two first radiation arms 111 overlap each other in the thickness direction of the circuit board 300. In this way, when the current directions of the two first transmission lines 140 are opposite, the electric fields formed by the two first transmission lines 140 can cancel each other and no radiation is generated.

[0151] The two first transmission lines 140 may also be close to each other while ensuring that the electric fields formed by the two first transmission lines 140 can cancel each other and prevent radiation.

[0152] The two second transmission lines 150 corresponding to the two second radiation arms 121 overlap each other in the thickness direction of the circuit board 300. In this way, when the current directions of the two second transmission lines 150 are opposite, the electric fields formed by the two second transmission lines 150 can cancel each other and no radiation is generated.

[0153] Likewise, when it is not ensured that the electric fields formed by the two second transmission lines 150 can cancel each other and no radiation is generated, the two second transmission lines 150 may also be close to each other.

[0154] Since the two first radiating arms 111 are formed on two surfaces of the circuit board 300 , it is also possible to prevent one of the two first transmission lines 140 from being covered by the other on the same side surface of the circuit board 300 , thereby ensuring normal radiation and grounding of the two first radiating arms 111 .

[0155] 7 in conjunction with FIG5 , when the RF port 320 on the circuit board 300 transmits a signal to the two second transmission lines 150 via the balun structure 130, the currents in the two second transmission lines 150 flow in opposite directions, generating no radiation, and the currents in the two second radiating arms 121 flow in the same direction. This allows one of the two second radiating arms 121 to radiate externally while also being grounded via the other of the two second radiating arms 121, thereby achieving both radiation and grounding for the second dipole 120.

[0156] It should be noted that the balun structure 130 can be an existing structure on the circuit board 300 of a communication device such as a bridge device. Alternatively, the balun structure 130 can be a structure added to the circuit board 300 of the communication device. The principle by which the balun structure 130 can achieve 180° phase shift can be determined using existing technologies and will not be further elaborated here.

[0157] As shown in Figures 6 and 7 , the balun structure 130 includes a microstrip balun. The microstrip balun includes a first microstrip balun 131 and a second microstrip balun 132. As shown in Figure 6 , the first microstrip balun 131 is located on the side of the circuit board 300 where the RF port 320 is located. As shown in Figure 7 , the second microstrip balun 132 is located on the side of the circuit board 300 opposite the first microstrip balun 131 and is grounded.

[0158] One of the two first radiation arms 111 is connected to the first microstrip balun 131 through the corresponding first transmission line 140 , and the other is connected to the second microstrip balun 132 through the corresponding first transmission line 140 , thereby achieving radiation and grounding of the first dipole 110 .

[0159] One of the second radiation arms 121 is connected to the first microstrip balun 131 through the corresponding second transmission line 150 , and the other is connected to the second microstrip balun 132 through the corresponding second transmission line 150 , thereby achieving radiation and grounding of the second dipole 120 .

[0160] The first transmission line 140 and the second transmission line 150 can both be microstrip 530 transmission lines or other linear structures capable of transmitting signals. The first transmission line 140 and the second transmission line 150 can also be integrated on the circuit board 300 by printing or other means.

[0161] As shown in FIG8 , a tapered transmission line 160 may be provided on at least one of the first transmission line 140 and the second transmission line 150 that are electrically connected to the first microstrip balun 131. The width of the tapered transmission line 160 gradually changes along its length. In other words, the tapered transmission line 160 is a portion of the first transmission line 140 or the second transmission line 150. During signal transmission, the provision of the tapered transmission line 160 enables better impedance matching.

[0162] The gradient transmission line 160 has a first section and a second section. Compared with the first section, the second section is closer to the first microstrip balun 131. The second section is conductive with the first microstrip balun 131. Along the direction toward the first microstrip balun 131, the line width of the gradient transmission line 160 in the second section may gradually decrease. For example, the gradient transmission line 160 may be formed in an inverted triangle or an inverted trapezoid in the second section. Along the direction toward the first microstrip balun 131, the line width of the gradient transmission line 160 in the first section may gradually increase. For example, the gradient transmission line 160 may be formed in a triangle or a trapezoid in the second section. In the present application, the shape of the gradient transmission line 160 is not particularly limited.

[0163] In Figure 8 , both the first transmission line 140 and the second transmission line 150 are provided with a tapered transmission line 160. In some embodiments, the tapered transmission line 160 can also be provided separately on the first transmission line 140 and the second transmission line 150. In this application, the location of the tapered transmission line 160 is not particularly limited.

[0164] After the feed source 100 is integrated on the circuit board 300 and the circuit board 200 , how to optimize the assembly process and yield rate of the feed source 100 and the circuit board 300 during the production process is also a technical problem that needs to be solved urgently.

[0165] FIG9 and FIG10 respectively illustrate partial schematic diagrams of the assembly of the circuit board 200 on the circuit board 300 from different perspectives.

[0166] As shown in FIG9 , when at least a portion of circuit board 200 is disposed within first slot 310 , circuit board 200 intersects with circuit board 300 and is connected via multiple (e.g., four) connecting portions 330 , thereby securing circuit board 200 to circuit board 300 via connecting portions 330 . As shown in FIG10 , connecting portions 330 may be distributed on the same surface of circuit board 200 . Connecting portions 330 may include, but are not limited to, soldering portions, thereby enabling soldering of circuit board 200 to circuit board 300 . For example, connecting portions 330 may include conductive adhesive portions.

[0167] Compared to the situation where multiple connecting portions 330 are arranged on different surfaces of circuit board 200 (multiple connecting portions 330 are distributed on both sides of the circuit board 200 in the thickness direction), by arranging connecting portions 330 on the same surface of circuit board 200, the connection between circuit board 200 and circuit board 300 can be completed on the same side of circuit board 200, without having to flip circuit board 200. This not only simplifies the connection process between circuit board 200 and circuit board 300, facilitates the connection between circuit board 300 and circuit board 200, helps improve the installation efficiency of circuit board 200 on circuit board 300, and improves the production efficiency of communication equipment, but also avoids the probability of damage caused by collision between the antenna and some equipment (such as communication devices) due to the flipping operation, thereby improving the yield rate of communication equipment.

[0168] Furthermore, by disposing the connection portion 330 on the same surface of the circuit board 200 , when the connection portion 330 is a soldering portion, the tooling for soldering can be simplified, which helps to reduce the production cost of the communication device.

[0169] As shown in Figure 9, when the connecting portion 330 is distributed on the same board surface of the circuit board 200, the connecting portion 330 can also be located between the second radiation arm 121 and the second transmission line 150, and conduct the second radiation arm 121 and the second transmission line 150, thereby achieving conduction between the second radiation arm 121 and the first microstrip balun 131 and the second microstrip balun 132.

[0170] Since the circuit board 200 is arranged in the first slot body 310 of the circuit board 300, if the first slot body 310 is located at the top edge of the circuit board 300, when the circuit board 300 is squeezed and deformed by external force on both sides of the length direction of the first slot body 310, the connection part 330 (such as the welding part) between the circuit board 200 and the circuit board 300 will cause it to fall off, affecting the assembly of the circuit board 200 on the circuit board 300, and even affecting the conduction between the second radiation arm 121 and the second transmission line 150.

[0171] As shown in FIG9 , the first slot 310 can be located in the middle region of the circuit board 300. The middle region of the circuit board 300 can be understood as the region including the center of the circuit board 300, rather than the edge region. This prevents the connection portion 330 (e.g., the soldering portion) from falling off when the circuit board 300 is squeezed on both sides of the first slot 310 along its length, thereby enhancing the stability of the connection between the circuit board 200 and the circuit board 300. At the same time, the conductive effect between the second radiating arm 121 and the second transmission line 150 will also be more stable.

[0172] The distance d1 between the first groove 310 and the top edge of the circuit board 300 can be greater than or equal to 3 mm and less than or equal to 10 mm to further enhance the stability of the connection portion 330 and prevent the connection portion 330 (such as the soldering portion) from falling off when the circuit board 300 is squeezed on both sides of the first groove 310 in the longitudinal direction. For example, the distance d1 can be 3 mm, 4 mm, 5 mm, 6 mm, etc.

[0173] In some embodiments, the antenna may further include a first reflector 400 (as shown in FIG3 ). The first reflector 400 has a reflecting surface. The reflecting surface of the first reflector 400 is a parabola. In this case, the first reflector 400 can be understood as a parabolic reflector in a parabolic antenna, and in this case, the antenna can be a parabolic antenna. The circuit board 300 can be located in the reflecting area of ​​the reflecting surface so that the communication device can be integrated into the antenna while making the antenna have the high gain characteristics of a parabolic antenna. Since the communication device and the antenna do not need to be connected through an external feeder, it is possible to avoid the external feeder affecting the gain and radiation pattern of the parabolic antenna, thereby improving the gain of the antenna and improving the signal quality of the communication device, thereby improving the coverage performance and coverage distance of the communication device, which is conducive to achieving long-distance wireless communication.

[0174] Parabolic antennas require that the dipole be designed at the focus of the parabola. In this application, if the first dipole 110 and the second dipole 120 are arranged at the same height plane on the circuit board 300 in the Z direction (as shown in FIG3 ), the first dipole 110 and the second dipole 120 will overlap in the Z direction, and the first transmission line 140 and the second transmission line 150 will also overlap, causing the antenna to interfere with the signal between the first dipole 110 and the second dipole 120, causing serious deterioration in the antenna performance and damaging the electrical performance of the communication device.

[0175] To this end, the first dipole 110 and the second dipole 120 of the present application are spaced apart on a line (not shown) connecting the focus and the center of the parabola. As shown in FIG9 , the second dipole 120 may be located below the first dipole 110.

[0176] If the second dipole 120 is located above the first dipole 110 , the second transmission line 150 will be extended, causing the second transmission line 150 and the first dipole 110 to overlap with each other, resulting in signal interference between the first dipole 110 and the second dipole 120 .

[0177] Therefore, when the second dipole 120 is located below the first dipole 110 , it is possible to avoid signal interference caused by the first dipole 110 and the second dipole 120 overlapping each other, thereby ensuring the performance of the antenna and the electrical performance of the communication device.

[0178] It should be noted that the positions of the focus and the center of the parabola can be found in the relevant description of the existing parabola reflector, which will not be repeated here.

[0179] As shown in FIG9 , in some embodiments, first dipole 110 can be located at the focus of a parabola to ensure that the placement of first dipole 110 complies with the design requirements for dipoles in a parabola antenna. In this case, the center of symmetry of the two first radiating arms 111 of first dipole 110 is also located at the focus of the parabola. In this case, second dipole 120 is located near the center of the parabola, and the center of symmetry of the two second radiating arms 121 of second dipole 120 is located below the focus of the parabola at the aforementioned connection.

[0180] Alternatively, in some embodiments, when first dipole 110 and second dipole 120 are spaced apart on a line (not shown) connecting the focus of the parabola and the center of the parabola, second dipole 120 can be located at the focus of the parabola, while first dipole 110 remains above second dipole 120, ensuring that the placement of second dipole 120 complies with the design requirements for dipoles in a parabola antenna. In this case, the center of symmetry of the two second radiating arms 121 in second dipole 120 is located at the focus of the parabola. The center of symmetry of the two first radiating arms 111 of first dipole 110 is located on the connection mentioned above and above the focus of the parabola. In the embodiments of the present application, the positions of first dipole 110 and second dipole 120 are not particularly limited.

[0181] The structure of the communication device will be further described below by taking the example that the first dipole 110 is located at the focus of the parabola and the second dipole 120 may be located below the first dipole 110 .

[0182] The phase center of a dipole is the center of the dipole's radiation pattern. Changes in the dipole's phase center directly affect antenna performance and communication quality. The dipole's phase center can also be understood as the center of symmetry between the dipole's two radiating arms.

[0183] The greater the separation between the first dipole 110 and the second dipole 120 on the aforementioned connecting line, the greater the isolation between the first dipole 110 and the second dipole 120. However, if the separation is too large, the second dipole 120 will be closer to the center of the parabola. In this case, the phase center of the second dipole 120 will deviate further from the focus of the parabola. This will cause the electromagnetic waves radiated by the second dipole 120 to have unequal phases when reaching the parabola's reflective surface (the aperture of the parabola antenna). After reflection, they will not all form parallel plane waves, resulting in increased sidelobes and reduced gain for the second dipole 120.

[0184] Therefore, the distance between the first dipole 110 and the second dipole 120 on the aforementioned connecting line is greater than or equal to one-ninth of the wavelength of the parabolic antenna's center frequency, and less than or equal to one-sixth of the wavelength of the parabolic antenna's center frequency. This effectively prevents signal interference between the first dipole 110 and the second dipole 120 while also preventing a reduction in the gain of the second dipole 120. For example, the distance between the first dipole 110 and the second dipole 120 on the connecting line can be one-eighth of a wavelength. In this case, the distance between the first dipole 110 and the second dipole 120 on the aforementioned connecting line is approximately (rounded off) 7 mm.

[0185] As shown in Figure 9 , the length of the first slot 310 is parallel to the aforementioned connecting line and the short side 220 of the circuit board 200. The circuit board 200 is provided with a second slot on the side where the second dipole 120 is located. The second dipole 120 is positioned adjacent to the slot opening of the second slot. When the circuit board 200 is positioned within the first slot 310, a portion of the circuit board 200 is positioned within the first slot 310 and rests on the slot wall of the first slot 310. The second slot is positioned below the first slot 310, such that the second dipole 120 is spaced below the first dipole 110 along the aforementioned connecting line. Furthermore, because the length of the first slot 310 is parallel to the aforementioned connection line and the short side 220 of the circuit board 200, when the circuit board 200 is inserted into the first slot 310, the circuit board 200 can be perpendicular to the circuit board 300, so that the second dipole 120 is arranged perpendicular to the first dipole 110, and a dipole unit of an orthogonal dual-polarization dipole is formed.

[0186] Because first dipole 110 and second dipole 120 are spaced apart on the aforementioned connecting line, the distances between first dipole 110 and second dipole 120 and the center of the parabola vary. This can lead to some differences in the gains of first dipole 110 and second dipole 120. For example, when the distance between first dipole 110 and second dipole 120 on the connecting line is 7 mm, the gain difference between first dipole 110 and second dipole 120 is 1 dBi, with the gain of second dipole 120 being smaller than that of first dipole 110.

[0187] To this end, as shown in Figure 9 , the communication device may further include a microstrip parasitic element 500. Microstrip parasitic element 500 is located on the side of the dipole element away from the communication device and is configured to at least increase the gain of the second dipole 120 to reduce the gain difference between the first dipole 110 and the second dipole 120. Reducing the gain difference between the first dipole 110 and the second dipole 120 can reduce the engineering focus operation time and improve the installation efficiency of the communication device. The gain difference can also be referred to as gain fluctuation.

[0188] It should be noted that the microstrip parasitic unit 500 can also reduce the angular fluctuation of the first dipole 110 and the second dipole 120 by at least improving the gain of the second dipole 120, thereby further reducing the operation time of engineering focusing and improving the installation efficiency of communication equipment.

[0189] The microstrip parasitic unit 500 includes a first microstrip unit 510 and a second microstrip unit 520. Each of the first microstrip unit 510 and the second microstrip unit 520 includes two microstrips. For ease of description, the microstrip in the first microstrip unit 510 is referred to as the first microstrip 530, and the microstrip in the second microstrip unit 520 is referred to as the second microstrip 540. The two first microstrips 530 in the first microstrip unit 510 are symmetrically arranged on the circuit board 300. For example, the two first microstrips 530 in the first microstrip unit 510 are arranged on the circuit board 300 in an axisymmetric manner.

[0190] The two second microstrips 540 in the second microstrip unit 520 are symmetrically arranged on the circuit board 200. Exemplarily, the two second microstrips 540 in the second microstrip unit 520 are arranged on the circuit board 200 in an axisymmetric manner.

[0191] As shown in FIG9 , when at least a portion of the circuit board 200 is disposed within the first slot 310, the two first microstrips 530 in the first microstrip unit 510 and the two second microstrips 540 in the second microstrip unit 520 are interconnected to form a microstrip parasitic unit 500. This allows the microstrip parasitic unit 500 to control the degree to which the gain of the first dipole 110 and the second dipole 120 is enhanced by the microstrip parasitic unit 500, thereby reducing the gain difference between the first dipole 110 and the second dipole 120. For example, when the microstrip parasitic unit 500 enhances the gain of the second dipole 120 more than the microstrip parasitic unit 500 enhances the gain of the first dipole 110, the gain difference and angle fluctuation between the first dipole 110 and the second dipole 120 can be reduced.

[0192] As shown in FIG9 , some connecting portions 330 may be located at the junction of the first microstrip 530 and the second microstrip 540. Other connecting portions 330 may be located at the intersection between the second radiating arm 121 and the second transmission line 150. When the connecting portion 330 is located at the junction of the first microstrip 530 and the second microstrip 540, the first microstrip 530 may further include a solder pad 511 (see FIG5 ). The solder pad 511 is located on the side of the first microstrip 530 facing the second radiating arm 121 and is connected to the first microstrip 530 to increase the connection area of ​​the connecting portion 330 to the circuit board 200 and the circuit board 300, thereby enhancing the connection between the circuit board 200 and the circuit board 300. The solder pad 511 may include, but is not limited to, a solder pad having a length and width of 1.8 x 1.8 mm.

[0193] The length of the first microstrip 530 is greater than or equal to one-ninth of the wavelength of the center frequency of the parabolic antenna, and less than or equal to one-seventh of the wavelength of the center frequency of the parabolic antenna. For example, the length of the first microstrip 530 may be one-eighth of the wavelength of the center frequency of the parabolic antenna. When the length of the first microstrip 530 is one-eighth of the wavelength of the center frequency of the parabolic antenna, the length of the first microstrip 530 may be 6.7 mm.

[0194] The length of the second microstrip 540 may be one tenth of the wavelength of the central frequency of the parabolic antenna.

[0195] By limiting the length of the first microstrip 530 , it is possible to prevent the radiation performance of the first dipole 110 from being affected by the excessive length of the first microstrip 530 .

[0196] If the distance between the first microstrip 530 and the second radiating arm 121 in the microstrip parasitic element 500 is one-quarter of the wavelength of the parabolic antenna's center frequency, the second radiating arm 121 and the microstrip parasitic element 500 generate in-phase induced electromotive forces, and the second dipole 120 achieves the maximum gain improvement. In this case, if the distance between the first microstrip 530 and the first radiating arm 111 in the microstrip parasitic element 500 is less than one-quarter of the wavelength of the parabolic antenna's center frequency, the induced electromotive force generated by the microstrip parasitic element 500 is small, and the first dipole 110 achieves a low gain improvement.

[0197] If the distance between the first microstrip 530 and the second radiating arm 121 is less than one-quarter wavelength of the center frequency of the parabolic antenna, the induced electromotive force generated by the microstrip parasitic element 500 is small, and the gain improvement value obtained by the second dipole 120 is low. In this case, the distance between the first microstrip 530 and the first radiating arm 111 in the microstrip parasitic element 500 is greater than one-quarter wavelength of the center frequency of the parabolic antenna. The first radiating arm 111 and the microstrip parasitic element 500 generate induced electromotive forces in phase, and the gain improvement value obtained by the first dipole 110 is maximized.

[0198] Therefore, the distance between the first microstrip 530 and the second radiating arm 121 in the microstrip parasitic unit 500 of the present application is one-quarter wavelength of the center frequency of the parabolic antenna. At this time, the distance between the first microstrip 530 and the second radiating arm 121 in the microstrip parasitic unit 500 is less than one-quarter wavelength of the center frequency of the parabolic antenna, so as to ensure that the gain enhancement effect of the microstrip parasitic unit 500 on the second dipole 120 is greater than the gain enhancement effect on the first dipole 110, thereby reducing the gain difference between the first dipole 110 and the second dipole 120.

[0199] As shown in FIG9 , the first microstrip 530 is closer to the first radiating arm 111 than the second microstrip 540. If the width of the first microstrip 530 is too large, the radiation performance of the first dipole 110 will be affected. If the width of the first microstrip 530 is too small, the gain improvement effect on the first dipole 110 and the second dipole 120 will be affected.

[0200] Therefore, the first microstrip 530 of the present application can be a microstrip line with a resistance of 50Ω to 77Ω. For example, when the length of the first microstrip 530 is one-eighth of the wavelength at the center frequency of the parabolic antenna, the width of the first microstrip 530 can be 0.8 mm. This ensures that the microstrip parasitic unit 500 improves the gain of the first dipole 110 and the second dipole 120 while avoiding any impact on the radiation performance of the first dipole 110.

[0201] To verify the effect of the microstrip parasitic unit 500 on reducing the gain difference between the first dipole 110 and the second dipole 120, the present application provides a comparative example and simulates the gain of the communication devices of the embodiment of the present application and the comparative example at the first dipole 110 and the second dipole 120. The difference between the communication device of the comparative example and the embodiment of the present application is that the microstrip parasitic unit 500 is not added.

[0202] As shown in FIG11 , the gain of the comparative example communication device at the first dipole 110 is 22.95 dBi. As shown in FIG12 , the gain of the communication device according to the embodiment of the present application at the first dipole 110 is 23.25 dBi. Thus, after adding the microstrip parasitic unit 500, the gain at the first dipole 110 is increased from 22.95 dBi to 23.25 dBi.

[0203] 13 , the gain of the comparative example communication device at the second dipole 120 is 22.23 dBi. As shown in FIG14 , the gain of the communication device of the embodiment of the present application at the second dipole 120 is 23.13 dBi.

[0204] As can be seen, after adding the microstrip parasitic unit 500, the gain at the second dipole 120 increases from 22.23 dBi to 23.13 dBi. Compared to the first dipole 110, the gain of the second dipole 120 is significantly improved, and after adding the microstrip parasitic unit 500, the gain difference between the second dipole 120 and the first dipole 110 is relatively small.

[0205] As shown in FIG. 15 , in some embodiments, the antenna may further include a second reflector 600 . The second reflector 600 is mounted on an end of the circuit board 300 away from the first reflector 400 . The second reflector 600 covers the dipole unit. This allows the second reflector 600 to re-reflect (secondary reflection) the signal reflected by the first reflector 400 , further increasing the gain of the dipole unit at the first dipole 110 and the second dipole 120 .

[0206] When the second reflector 600 is mounted on the circuit board 300 , the second reflector 600 is fixed on the circuit board 300 . The reflective surface of the second reflector 600 is smaller than the reflective surface of the first reflector 400 .

[0207] Specifically, the second reflector 600 is mounted on the extension portion 340 of the circuit board 300. The extension portion 340 can be mounted within the second reflector 600, and the second reflector 600 can be secured to the circuit board 300 by snapping or other means. Compared to the first reflector 400, the second reflector 600 is smaller in size. Therefore, the extension portion 340 can be a local protrusion on the edge of the circuit board 300 to facilitate installation within the second reflector 600. It should be noted that as the size of the second reflector 600 increases, the size of the extension portion 340 can also increase accordingly. Therefore, in this application, the size of the extension portion 340 is not further limited.

[0208] The first reflector 400 and the second reflector 600 are both reflectors of the antenna. In some embodiments, the reflector of the antenna may include only the first reflector 400, in which case the antenna has the high gain and long-distance transmission characteristics of a parabolic antenna. In other embodiments, the reflector of the antenna may include only the second reflector 600, so that the antenna can be used as a directional antenna (e.g., a 5dBi directional antenna) for connection to a communication device. In other embodiments, the reflector of the antenna may include both the first reflector 400 and the second reflector 600 to further increase the gain of the antenna.

[0209] Figures 16 and 17 provide schematic structural diagrams of another communication device from different viewing angles. As shown in Figures 16 and 17, the communication device may further include a housing 480. The circuit board 300 is located within the housing 480 to prevent components of the communication device from being exposed on the surface of the communication device. The circuit board 300, circuit board 200, and second reflector 600 may all be located within the housing 480 to prevent them from being exposed on the surface of the communication device, thereby enhancing the safety and aesthetics of the communication device.

[0210] The housing 480 may be a plastic housing 480. The housing 480 may be located on the middle portion of the reflective surface of the first reflector 400 and connected to the reflective surface of the first reflector 400.

[0211] As shown in Figure 17, the first reflector 400 can include two arc structures 410, which are connected to each other to form the first reflector 400. While forming the first reflector 400, the size of the packaging structure of the first reflector 400 can be reduced to facilitate the transportation of the first reflector 400.

[0212] The two arc-shaped structures 410 are equal arc structures. The first reflector 400 can be a circular reflective surface with a diameter of 360 mm at the aperture. The two arc-shaped structures 410 can be connected by fasteners, etc. The fasteners can include but are not limited to screws, bolts, etc.

[0213] The antenna with the first reflector 400 has a focal length-to-aperture ratio of 0.4, an antenna gain of 23 dBi, a horizontal angle of 10°, and a vertical angle of 9°. The horizontal angle of the antenna can be understood as the angle of the main lobe of the antenna when parallel to the ground. The vertical angle of the antenna can be understood as the angle of the main lobe of the antenna when perpendicular to the ground.

[0214] 17 , the first reflector 400 may have a plurality of through holes 411 , which are distributed on the reflective surface of the first reflector 400 to improve the wind resistance and aesthetics of the antenna. The through holes 411 may be located on the arc structure 410 .

[0215] In addition, the traditional parabolic antenna is connected to an antenna fixing structure on the back of the parabolic reflector. For example, the antenna fixing structure can be a fixing base on the back of the parabolic reflector. The back of the parabolic reflector can be understood as the side of the parabola away from the parabola. There is only one clamp provided on the antenna fixing structure, which only supports the installation of the parabolic antenna on the vertical pole (the pole perpendicular to the ground) at the installation site, which is difficult to meet the installation requirements of the parabolic antenna in some scenarios with complex site resources and high installation environment requirements. For example, the communication equipment on the top floor of some buildings requires direct installation of the horizontal pole (the pole parallel to the ground) fixed to the top floor wall. Therefore, the parabolic antenna is required to support the installation mode of the horizontal pole and the vertical pole so as to meet more equipment construction and installation scenarios.

[0216] As shown in Figures 18 and 19, the parabolic antenna further includes a mounting base 700 and a clamp 800. The mounting base 700 is mounted on the side of the first reflector 400 facing away from the feed source 100. The mounting base 700 has a first recess and a second recess. The first recess and the second recess intersect. The number of the first recess and the second recess can be one, so that each first recess and the second recess can correspond to a fixing rod 900.

[0217] Alternatively, when the parabolic antenna needs to be fixed on more than two fixing rods 900 , the number of the first recessed portions and the second recessed portions may be more than two. Therefore, the number of the first recessed portions and the second recessed portions is not particularly limited.

[0218] For ease of description, the first recess and the second recess are collectively referred to as the recess 710 below. That is, the mounting base 700 has two intersecting recesses 710. The shapes of the two recesses 710 are adapted to the shape of the circumferential outer wall of the fixing rod 900. In other words, the shapes of the two recesses 710 are the same as or similar to the shape of the circumferential outer wall of the fixing rod 900. For example, the recess 710 can be an arc-shaped recessed surface that matches the shape of the circumferential outer wall of the fixing rod 900. In addition, the end of the recess 710 in the longitudinal direction extends to the side wall of the mounting base 700 and forms a notch (not marked) on the side wall of the mounting base 700. The longitudinal direction of the recess 710 is the same as the longitudinal direction of the fixed rod 900. The recessed portion 710 of the mounting base 700 is exposed on the side wall of the mounting base 700. When the mounting base 700 of the parabolic antenna is fixed to the fixing rod 900, the fixing rod 900 can be fixed to the recessed portion 710 and extend from the side wall of the mounting base 700. The recessed portion 710 can limit the assembly of the mounting base 700 on the fixing rod 900. The length direction of the recessed portion 710 is the same as the length direction of the fixing rod 900 to which it is fixed.

[0219] The clamp 800 is detachably mounted on the mounting base 700 and can be selectively positioned in either of the two recessed portions 710 to secure the mounting base 700 to the fixing rod 900. Thus, through the arrangement of the clamp 800 and the mounting base 700, the parabolic antenna is secured to the fixing rod 900. Furthermore, because the clamp 800 can be selectively positioned in either of the two recessed portions 710, the parabolic antenna can be secured to either the horizontal or vertical rod of the fixing rod 900 by changing the position of the clamp 800 on either mounting base 700. This allows the communication device to adapt to different installation sites, thereby enabling installation of the communication device on horizontal or vertical rods at different installation sites.

[0220] Two recessed portions 710 are vertically disposed on the mounting base 700. There may be two clamps 800, which may be spaced apart along the extending direction of the recessed portion 710 so that both clamps 800 embrace the horizontal or vertical rod, allowing the horizontal or vertical rod to be fixed within one of the two recessed portions 710, thereby enhancing the stability of the communication device when installed on the fixing rod 900.

[0221] 18 , when the parabolic antenna is fixed to the vertical rod in the fixing rod 900 , two hoops 800 may be spaced apart at the recessed portion 710 parallel to the axial direction of the vertical rod so that the two hoops 800 may be wrapped around the circumferential outer wall of the vertical rod.

[0222] 19 , when the parabolic antenna is fixed to the crossbar in the fixing rod 900 , two hoops 800 may be spaced apart at the recessed portion 710 parallel to the axial direction of the crossbar so that the two hoops 800 may be wrapped around the circumferential outer wall of the crossbar.

[0223] If the mounting rod 900 at the installation site includes, in addition to the vertical and horizontal rods, a rod 900 that is tilted relative to the ground (referred to as an inclined rod), the mounting base 700 may further include a third recessed portion to facilitate securing the parabolic antenna. The end of the third recessed portion extends axially along the inclined rod. The clamp 800 may also be selectively positioned in any of the third recessed portions to facilitate securing the mounting base 700 to the inclined rod.

[0224] As shown in FIG. 19 , the mounting seat 700 may have a through hole 720 , and the clamp 800 may be inserted into the through hole 720 to achieve a detachable connection between the clamp 800 and the mounting seat 700 .

[0225] As shown in Figures 20 and 21, the parabolic antenna also includes a connecting base 430. The connecting base 430 is installed on the first reflector 400 and is located between the first reflector 400 and the mounting base 700. The connecting base 430 has a connecting shaft 431. The mounting base 700 has a sleeve portion 730. The sleeve portion 730 is sleeved on the circumferential outer side of the connecting shaft 431 and is connected to the connecting shaft 431. The connecting shaft 431 is rotatably arranged relative to the sleeve portion 730. In this way, when the connecting shaft 431 rotates relative to the sleeve portion 730, the angle of the connecting base 430 relative to the mounting base 700 can be adjusted, and then the horizontal installation angle of the communication device during installation can be adjusted to facilitate the focusing of the communication equipment during the construction process.

[0226] For example, the sleeve portion 730 may be a sleeve shaft, wherein the sleeve portion 730 has an assembly hole 731 therein, and the connecting shaft 431 is located in the assembly hole 731 , so that the sleeve portion 730 is sleeved on the circumferential outer side of the connecting shaft 431 .

[0227] The connecting seat 430 is further equipped with a first connecting member 450. The connecting shaft 431 has a first connecting hole 4311. The first connecting member 450 can be inserted into the first connecting hole 4311 and fixed to the sleeve portion 730 to achieve connection between the sleeve portion 730 and the connecting shaft 431.

[0228] As one possible approach, the first connector 450 can be screwed and fixed to the socket portion 730. The end of the first connector 450 can be threaded, and the end of the socket portion 730 can be screwed into a first locking member (not shown) to secure the first connector 450 to the socket portion 730. The first locking member can be a structural member such as a nut. The first locking member can be located outside the socket portion 730. Alternatively, the first locking member can be integrated into the socket portion 730.

[0229] Of course, the first connector 450 can also be fixed to the sleeve portion 730 in other ways. For example, the first connector 450 can also be fixed to the sleeve portion 730 by snapping. In this application, the fixing method of the first connector 450 on the sleeve portion 730 is not further limited.

[0230] The structure of the communication device will be further described below by taking the example of the first connecting member 450 being screwed and fixed on the socket portion 730 .

[0231] As shown in Figures 20 and 21, the connecting base 430 is also provided with a first knob 440. The first knob 440 is located on a side of the connecting base 430 away from the mounting base 700. The first knob 440 defines a second connecting hole 441. The first connecting member 450 can be sequentially inserted into the second connecting hole 441 and the first connecting hole 4311 and fixed to the socket 730. For example, the first connecting member 450 can be fixed to the socket 730 by screwing. The first knob 440 can be used to adjust the horizontal installation angle of the communication device.

[0232] As shown in Figure 20, the first connector 450 has a first connector 451. The first connector 451 can be a polygonal structure. The first connecting hole 4311 is also a polygonal hole with the same circumferential outer wall as the first connector 451. The first connector 451 is located within the first connecting hole 4311. When the first knob 440 is rotated in the first direction, the first knob 440 will cause the first connector 451 to rotate simultaneously, thereby securing the first connector 450 to the socket 730 by rotating the first knob 440. The second direction is opposite to the first direction. For example, the first direction can be referred to as the v+ direction, and the second direction can be referred to as the v- direction. When the first knob 440 is rotated in the second direction, the first knob 440 will also cause the first connector 451 to rotate simultaneously, thereby releasing the first connector 450 from the socket 730 by rotating the second knob 470.

[0233] When it is necessary to adjust the horizontal installation angle of the communication device, the first knob 440 can be rotated along the second direction to loosen the fixation of the first connecting member 450 on the socket 730, rotate the connecting seat 430, adjust the horizontal installation angle of the communication device, and then rotate the first knob 440 along the first direction to fix the first connecting member 450 on the socket 730.

[0234] 20 and 21 , the connecting base 430 is provided with meshing teeth 433 on the side on which the connecting shaft 431 is provided, and the sleeve portion 730 is also provided with meshing teeth 433 on the side facing the connecting base 430. When the connecting shaft 431 is assembled into the sleeve portion 730, the meshing teeth 433 on the connecting base 430 and the meshing teeth 433 on the sleeve portion 730 mesh with each other, thereby increasing the friction between the connecting base 430 and the sleeve portion 730 in the direction of rotation of the connecting shaft 431 when the connecting base 430 rotates relative to the sleeve portion 730, thereby ensuring that the angle of the connecting base 430 relative to the sleeve portion 730 remains fixed.

[0235] As shown in Figure 22 , the first reflector 400 has a mounting base 420. The connecting base 430 has a connecting arm 432. The connecting arm 432 can be integrally connected to a connecting shaft 431. The connecting arm 432 is positioned to the side of the mounting base 420 and is rotatably connected to the mounting base 420. By rotating the mounting base 420 relative to the connecting arm 432, the pitch angle of the communication equipment during installation can be adjusted, facilitating focus adjustment during installation.

[0236] The number of connecting arms 432 can be two. The two connecting arms 432 are distributed on opposite sides of the fixed base 420 and are both rotatably connected to the fixed base 420. A third connecting hole 4321 is provided on each connecting arm 432. The fixed base 420 is provided with a circular protrusion 421 at a position corresponding to each connecting arm 432. The circular protrusion 421 is assembled into the third connecting hole 4321 on the corresponding connecting arm 432 to achieve a rotatable connection between the connecting arm 432 and the fixed base 420. The provision of two connecting arms 432 can enhance the stability of the connection between the connecting base 430 and the fixed base 420, and can also enhance the stability of the fixed base 420 when rotating relative to the connecting arm 432.

[0237] The structure of the communication device is further described below by taking two connecting arms 432 as an example.

[0238] As shown in FIG23 , the fixing base 420 is also equipped with a second connecting member 460. The two connecting arms 432 each have a fourth connecting hole 4322. The fourth connecting hole 4322 is an arc-shaped hole. The fixing base 420 has a fifth connecting hole (not shown). The second connecting member 460 can be inserted into the fifth connecting hole and the two fourth connecting holes 4322 and fixed to the connecting arms 432 to further connect the connecting base 430 to the fixing base 420.

[0239] As one possible approach, the second connecting member 460 can be screwed onto and fixed to the connecting arm 432. The end of the second connecting member 460 can be threaded, and the end of the second connecting member 460 can be screwed into the second locking member 490 to secure the second connecting member 460 to the connecting arm 432. The second locking member 490 can be a structural member such as a nut. The second locking member 490 can be located outside the connecting arm 432. Alternatively, the second locking member 490 can be integrated into the connecting arm 432.

[0240] Of course, the second connecting member 460 can also be fixed to the sleeve portion 730 in other ways. For example, the second connecting member 460 can also be fixed to the connecting arm 432 by snapping. In this application, the fixing method of the second connecting member 460 on the connecting arm 432 is not further limited.

[0241] The structure of the communication device will be further described below by taking the second connecting member 460 being screwed and fixed on the connecting arm 432 as an example.

[0242] As shown in Figures 22 and 23, the parabolic antenna also includes a second knob 470. The second knob 470 is located on the side of the connecting base 430 away from the fixing base 420. The second knob 470 has a sixth connecting hole 471 therein. The second connecting member 460 can be inserted into the sixth connecting hole 471, the fifth connecting hole, and the two fourth connecting holes 4322 and fixed to the connecting arm 432. For example, the second connecting member 460 can be fixed to the connecting arm 432 by screwing. By rotating the second knob 470, the pitch angle of the communication device during installation can be adjusted to facilitate focusing of the communication device during installation.

[0243] As shown in Figure 23, the second connecting member 460 has a second connecting head 461. The second connecting head 461 can be a polygonal structure. The sixth connecting hole 471 is also a polygonal hole with the same circumferential outer wall as the second connecting head 461. The second connecting head 461 is located in the sixth connecting hole 471. By rotating the second knob 470 in two opposite directions, the second connecting member 460 can be fixed to the connecting arm 432, or the second connecting member 460 can be unfastened from the connecting arm 432. For details, please refer to the above description of the first knob 440 and the first connecting member 450, which will not be repeated here.

[0244] It should be noted that when it is necessary to adjust the pitch angle of the communication device during installation, the second knob 470 can be rotated in one direction and the fixing base 420 can be rotated. After the pitch angle of the communication device is adjusted, the second knob 470 can be rotated in the other direction to fix the second connecting member 460 on the connecting arm 432.

[0245] As shown in FIG22 , the connecting arm 432 also has a rotation angle scale 4323 on the side of the third connecting hole 4321. This allows the user to directly determine the rotation angle of the mounting base 420 relative to the mounting base 430 by observing the position of the second connecting member 460 on the scale 4323, thereby enabling better adjustment of the pitch angle of the communication device. For example, when the pitch angle of the communication device is 0°, the second connecting member 460 is located at the 0 mark on the scale 4323. To achieve a desired pitch angle of 5°, the mounting base 420 can be rotated so that the second connecting member 460 is located at the 5 mark on the ground-facing side of the 0 position on the scale 4323.
