Description

Technical Field

[0042] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part rather than all of the embodiments of the present disclosure. Usually, the components of the embodiments of the present disclosure described and illustrated in the accompanying drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed present disclosure, but merely represents selected embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0043] Unless otherwise defined, the technical terms or scientific terms used in this disclosure shall have the ordinary meanings as understood by those of ordinary skill in the field to which this disclosure pertains. The terms "first", "second" and similar terms used in this disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, terms such as "a", "an" or "the" do not denote a quantity limitation, but mean that there is at least one. Terms such as "including" or "comprising" mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items. Terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0044] As used in this disclosure, "a plurality or several" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0045] In the related art, for example, the connection between the radome and the outer housing is achieved through snap fasteners. However, the number of disassembly times of the snap fasteners is usually limited, and the service life is not ideal. In addition, the related radome installation method does not consider the influence of the material of the radome itself and the radome structure on signal radiation. For example, the embedded studs or wire inserts themselves need to occupy a certain space. In addition, in order to make the embedded structure stable, affected by the lightweight of the material of the radome itself, such as fiberglass and resin, etc., if the radome wants to accommodate the embedded studs or wire inserts, it needs to be achieved by thickening the side wall of the radome. However, the increase in the side wall thickness is not conducive to the uniform radiation of the antenna signals around the radome. Thus, it is relatively difficult to ensure the stable fixation and sealing between the radome and the outer housing while ensuring that the internal antenna radiation signal is not affected and meeting the requirement of frequent disassembly.

[0046] In view of this, the embodiments of this disclosure provide a radome that can ensure that the signal radiation of the internal antenna is not affected, and on the premise of meeting the requirement of frequent disassembly, further ensure the stable fixation between the radome and the outer housing.

[0047] Figure 1 It is the overall schematic diagram of the antenna packaging structure provided by the embodiments of this disclosure. Figure 2a and Figure 2b respectively are Figure 1 the exploded views of the structure shown from different perspectives. Figure 3 isFigure 1 A partial cross-sectional view of the antenna packaging structure from a certain perspective of the structure. Figure 4 A schematic diagram of a first side wall of a radome provided in an embodiment of the present disclosure.

[0048] like Figure 1 , Figure 2a and Figure 2b As shown, the antenna packaging structure includes a antenna cover 11, an outer shell 12 and a connecting structure 13.

[0049] like Figure 3 As shown, the radome 11 includes a top cover 111 and a first side wall 112 connected to the edge of the top cover 111 .

[0050] Exemplarily, the top cover 111 is an arched top cover 111, including a flat portion 111a and a connecting portion 111b connected to and surrounding the flat portion 111a, and one end of the connecting portion 111b away from the flat portion 111a is connected to the first side wall 112. A reference plane where the connecting portion 111b is located and a reference plane where the flat portion 111a is located form a dihedral angle, which is greater than 90° and less than 180°, which can not only increase the accommodation space of the antenna cover 11, but also ensure the structural stability of the antenna cover 11.

[0051] Exemplarily, the flat portion 111 a and the connecting portion 111 b are an integrally formed structure.

[0052] like Figure 3 As shown, the first side wall 112 is connected around the connecting portion 111b, and the first side wall 112 extends downward along a side away from the flat portion 111a. The reference plane where the first side wall 112 is located is approximately perpendicular to the reference plane where the flat portion 111a is located.

[0053] Exemplarily, the flat portion 111 a , the connecting portion 111 b and the first side wall 112 are an integrally formed structure.

[0054] like Figure 3 and Figure 4 As shown, the first side wall 112 includes a first main body portion 112a and a first protruding portion 112b; the first protruding portion 112b is connected to an end of the first main body portion 112a away from the top cover 111, and extends in a direction away from the top cover 111. The first protruding portion 112b mainly extends downward in a direction away from the flat portion 111a in the top cover 111. The reference surface where the first protruding portion 112b is located is coplanar with the reference surface where the first main body portion 112a is located.

[0055] Exemplarily, the first main body portion 112a and the first protruding portion 112b are an integrally formed structure.

[0056] It should be noted that the size of the first main body 112a can be set according to the size of the final accommodating structure of the actual internal enclosed space Q, and the embodiment of the present disclosure does not specifically limit it. The size of the first protrusion 112b can be set according to the actual size of the connecting structure 13. Different connecting structures 13 have different set sizes of the first protrusion 112b, and the embodiment of the present disclosure does not specifically limit it.

[0057] like Figure 3 As shown, at least a portion of the structure of the first side wall 112 is located on a side of the outer shell 12 away from the closed space Q. Specifically, the first protrusion 112 b is located on a side of the outer shell 12 away from the closed space Q.

[0058] like Figure 4 As shown, the first protruding portion 112 b has an opening V. The opening V completely penetrates the first protruding portion 112 b along the thickness direction of the first protruding portion 112 b.

[0059] like Figure 3 As shown, the connection structure 13 is connected to the outer shell 12 through the opening V to form a closed space Q for accommodating the antenna structure.

[0060] Exemplarily, the connection structure 13 may be a connection structure such as a screw or a stud.

[0061] Exemplarily, at least part of the connection structure 13 passes through the opening V and is inserted into the outer shell 12, thereby achieving connection with the outer shell 12, that is, fixing the antenna cover 11 to the outer shell 12. The connection structure 13 is detachable. In the disassembled state, the connection structure 13 is pulled out of the outer shell 12 and detached from the opening V, so that the antenna cover 11 and the outer shell 12 are not connected, and the antenna cover 11 and the outer shell 12 are disassembled. By connecting the antenna cover 11 and the outer shell 12 with the help of the connection structure 13, compared with the integrated buckle design, the connection of the connection structure 13 is more stable and has a longer service life.

[0062] For example, Figure 2a and Figure 2b As shown, the first protrusions 112b include a plurality of protrusions 112b that are evenly distributed and connected to the first main body 112a. For example, the first main body 112a includes four surfaces connected end to end, each surface is provided with two first protrusions 112b, the spacing between the two first protrusions 112b corresponding to each surface is equal, and the two first protrusions 112b corresponding to each surface are symmetrically distributed with the center line of the surface as the symmetry axis.

[0063] Of course, the first main body portion 112a may also be a ring-shaped structure, in which case the plurality of first protruding portions 112b may be distributed at equal intervals.

[0064] It should be noted that the first protruding portions 112b correspond one-to-one to the connecting structures 13. The more the number of the first protruding portions 112b, the more the number of the connecting structures 13 means. The smaller the spacing between the first protruding portions 112b, the smaller the spacing between the connecting structures 13 also means. In this way, the connection is more stable, but the corresponding installation complexity is higher, the installation efficiency is lower, and the cost is larger. Therefore, the number and spacing of the first protruding portions 112b can be set by comprehensively considering various factors and experiences, and the specific values are not specifically limited in the embodiments of the present disclosure.

[0065] In some embodiments, the thickness of the top cover 111 is the same as that of the first side wall 112, ensuring the thickness consistency of the radome 11, thereby improving the uniformity of multi-directional signal radiation.

[0066] At the same time, the connecting structure 13 of the present disclosure realizes the stable connection of the radome 11 and the outer housing 12 by means of the opening V located at the first protruding portion 112b, creating conditions for realizing the thickness consistency of the top cover 111 and the first side wall 112, and avoiding the influence of the uneven thickness of the first side wall 112 and the top cover 111 on the radiation signal.

[0067] In some embodiments, the present disclosure creates a thin and light antenna packaging structure, and sets the thickness of the top cover 111 and the first side wall 112 to be between 1.5 mm and 3 mm.

[0068] Optionally, the thickness of the top cover 111 is 1.5 mm, and the thickness of the first side wall 112 is 1.5 mm.

[0069] Optionally, the thickness of the top cover 111 is 2 mm, and the thickness of the first side wall 112 is 2 mm.

[0070] Optionally, the thickness of the top cover 111 is 2.5 mm, and the thickness of the first side wall 112 is 2.5 mm.

[0071] Optionally, the thickness of the top cover 111 is 3 mm, and the thickness of the first side wall 112 is 3 mm.

[0072] The present disclosure can not only realize a thin and light antenna packaging structure, but also ensure the thickness consistency of the radome 11, thereby improving the uniformity of multi-directional signal radiation. The thin and light radome 11 further improves the signal radiation efficiency.

[0073] In some embodiments, such as Figure 2a 、 Figure 2b and Figure 3 shown, the connecting structure 13 is the second screw 131, and the first side wall 112 is fixed on the second side wall 122 by a threaded connection method. The specific connecting structure 13 is as follows.

[0074] Figure 5 ForFigure 3 The enlarged view of the AA' area is shown in Figure 2. Figure 5 As shown, the second screw 131 includes a second screw head 131 a and a second stud 131 b connected to the second screw head 131 a.

[0075] like Figure 3 As shown, the outer shell 12 includes a bottom shell 121 and second side walls 122 respectively connected to different edges of the bottom shell 121 .

[0076] Exemplarily, the bottom shell 121 and the second side wall 122 are an integrally formed structure.

[0077] like Figure 5 As shown, the second side wall 122 has a second threaded hole 21. The opening V and the second threaded hole 21 are arranged one by one; the second screw head 131a is located in the opening V, and the second stud 131b is matched and connected with the second threaded hole 21, and the first side wall 112 and the second side wall 122 are connected through the second stud 131b and the second screw head 131a.

[0078] like Figure 5 As shown, at least a portion of the first side wall 112 is located on a side of the second side wall 122 away from the closed space Q. The first protrusion 112 b of the first side wall 112 is located on a side of the second side wall 122 away from the closed space Q.

[0079] Assembly process: The opening V and the second threaded hole 21 are arranged one by one, and the second stud 131b in the second screw 131 passes through the opening V and is screwed into the second threaded hole 21 on the second side wall 122. When the second stud 131b is tightened, the second screw head 131a is stuck in the opening V, thereby supporting and fixing the entire antenna cover 11.

[0080] In some embodiments, Figure 5 As shown, the antenna packaging structure also includes a screw gasket 14; the second stud 131b is connected to the second threaded hole 21 through a through hole passing through the screw gasket 14; the screw gasket 14 includes a first surface and a second surface arranged opposite to each other, the first surface contacts the side of the first side wall 112 close to the closed space Q, and the second surface contacts the side of the second side wall 122 away from the closed space Q.

[0081] Assembly process: The opening V and the second threaded hole 21 are arranged in one-to-one correspondence, and the second stud 131b in the second screw 131 passes through the opening V and the through hole of the screw washer 14 in sequence and is screwed into the second threaded hole 21 on the second side wall 122. When the second stud 131b is tightened, the second screw head 131a is stuck in the opening V. At this time, the screw washer 14 is between the first side wall 112 of the antenna cover 11 and the second side wall 122 of the outer shell 12, and can adjust the tolerance gap between the first side wall 112 and the second side wall 122 to reduce the rigid collision between the two.

[0082] When the second screw 131 is in the tightened state, the second screw head 131a is completely immersed in the opening V, preventing the second screw 131 from protruding from the radome 11.

[0083] Exemplarily, on the side of the second screw head 131a away from the second stud 131b, there is a groove for fastening. The style of this groove is not limited. For example, it can be a slotted head, or it can also be an internal hexagonal socket, etc.

[0084] In some embodiments, as Figure 5 shown, the opening V includes a first sub-hole and a second sub-hole, and the first sub-hole and the second sub-hole are connected. The first sub-hole is closer to the side of the closed space Q than the second sub-hole. The first sub-hole is a tapered hole, and the diameter of the first sub-hole gradually increases in the direction away from the second sub-hole. The second sub-hole is a cylindrical hole.

[0085] As Figure 5 shown, the diameter of the second screw head 131a gradually increases in the direction away from the second stud 131b; the second screw head 131a has a clearance fit with the first sub-hole and can be stuck in the first sub-hole.

[0086] Figure 6a It is a schematic diagram of the state of the sealing structure provided by the embodiment of the present disclosure before being pressed, Figure 6b It is a schematic diagram of the sealing structure provided by the embodiment of the present disclosure in the deformed state after being pressed.

[0087] In some embodiments, as Figure 6a and Figure 6b shown, the antenna packaging structure further includes a sealing structure 15.

[0088] As Figure 3 shown, the outer housing 12 includes a bottom shell 121 and a second side wall 122 connected to the edge of the bottom shell 121. The second side wall 122 extends upward on the side away from the bottom shell 121. The reference plane where the second side wall 122 is located is approximately perpendicular to the reference plane where the bottom shell 121 is located.

[0089] Exemplarily, the reference plane where the second side wall 122 is located is approximately parallel to the reference plane where the first side wall 112 is located.

[0090] Exemplarily, the bottom shell 121 and the second side wall 122 are an integrally formed structure.

[0091] As Figure 6a and Figure 6b shown, the second side wall 122 includes a second main body portion 122a and a second protruding portion 122b. The second protruding portion 122b is located at one end of the second main body portion 122a away from the bottom shell 121 and is connected to the side of the second main body portion 122a away from the closed space Q.

[0092] Exemplarily, the second main body portion 122a and the second protruding portion 122b are of an integrally formed structure.

[0093] As Figure 6a and Figure 6b shown, the dimension of the second protruding portion 122b in the Z direction is smaller than the thickness of the screw gasket 14, that is, the length by which the second protruding portion 122b protrudes from the second main body portion 122a is smaller than the thickness of the screw gasket 14. In this way, when the radome 11 is assembled, the second screw 131 can be tightened without interfering with the second protruding portion 122b. However, since the length by which the second protruding portion 122b protrudes from the second main body portion 122a is smaller than the thickness of the screw gasket 14, there is a gap between the first side wall 112 and the second side wall 122, and the two need to be sealed. Therefore, the sealing structure 15 is required. Specifically, the sealing structure 15 is connected to the surface of the second protruding portion 122b close to the bottom case 121 and abuts against the first main body portion 112a and the second main body portion 122a, so as to realize the sealing between the radome 11 and the outer housing 12.

[0094] In the sealed state, the sealing structure 15, the first main body portion 112a and the second main body portion 122a are closely attached to each other without gaps, realizing the sealing between the radome 11 and the outer housing 12.

[0095] Exemplarily, the sealing structure 15 can be an elastic sealing ring 151 that surrounds the second main body portion 122a and is pasted on the surface of the second protruding portion 122b close to the bottom case 121. The height of the elastic sealing ring 151 can be slightly greater than the thickness of the screw gasket 14. By tightening the second screw 131, the first main body portion 112a continuously approaches the elastic sealing ring 151, so that the elastic sealing ring 151 is closely attached to the first main body portion 112a and the second main body portion 122a, realizing the sealing effect.

[0096] Figure 7 For Figure 1 a partial cross-sectional view of the antenna packaging structure from another perspective of the structure, Figure 8 is a schematic diagram of the sealing ring fitting the outer housing, Figure 9a is a schematic diagram of the positional relationship between the sealing ring and the expansion frame at the initial stage of the sealed assembly, Figure 9b is a schematic diagram of the first screw pushing to compress the sealing ring.

[0097] In some embodiments, as Figure 2a , Figure 2b , Figure 6a , Figure 6b , Figure 7 , Figure 9a and Figure 9b shown, the sealing structure 15 includes a sealing ring 151 and an expansion frame 152.

[0098] Exemplarily, the sealing ring 151 is an elastic sealing ring 151 .

[0099] Exemplarily, the expansion frame 152 is a support frame with a greater rigidity than the sealing ring 151 and is not easily deformed. For example, the material of the expansion frame 152 is a metal or alloy support.

[0100] like Figure 7 and Figure 9b As shown, the antenna packaging structure also includes a first screw 16, which pushes the expansion frame 152 to squeeze the sealing ring 151 by tightening the thread to achieve sealing. The specific position structure is as follows.

[0101] like Figure 7 and Figure 9b As shown, the first screw 16 includes a first screw head 161 and a first stud (not shown in the figure) connected to the first screw head 161; the first screw head 161 is closer to the bottom shell 121 than the first stud.

[0102] Exemplarily, a side of the first screw head 161 away from the first stud has a fastening groove, and the style of the groove is not limited, for example, it can be a straight slot, or a hexagon socket slot, etc.

[0103] like Figure 8 and Figure 9b As shown, the sealing ring 151 is bonded to the surface of the second protrusion 122 b close to the bottom shell 121 .

[0104] like Figure 6a , Figure 6b , Figure 9a and Figure 9b As shown, the expansion frame 152 is disposed on a side of the sealing ring 151 away from the second protruding portion 122 b.

[0105] In the initial stage of seal assembly, such as Figure 6a and Figure 9a As shown, there is a certain gap between the sealing ring 151 and the expansion frame 152. The sealing ring 151 and the first main body 112a are not tightly fitted, and there may even be a certain gap.

[0106] like Figure 6a , Figure 6b , Figure 7 and Figure 9b As shown, the second main body 122a has a first threaded hole (not shown in the figure), the first stud is connected with the first threaded hole, and the expansion frame 152 is squeezed and fixed by the first screw head 161. The expansion frame 152 squeezes the sealing ring 151 to seal the first side wall 112 and the second side wall 122.

[0107] like Figure 7 and Figure 9bAs shown, the second main body portion 122a has a blind groove recessed into the enclosed space Q, and this blind groove penetrates through the bottom shell 121. During the sealing process, the first screw 16 is pushed into the blind groove, and as the first stud is continuously screwed into the first threaded hole, it drives the first screw head 161 to continuously press against the expansion frame 152. The expansion frame 152 is continuously pressed, further squeezing the sealing ring 151. The squeezing process can also be referred to Figure 6a and Figure 6b , thereby achieving a tight fit between the sealing ring 151 and the first main body portion 112a and the second main body portion 122a.

[0108] In some embodiments, Figure 10a is a cross-sectional view of the sealing ring. As shown in Figure 10a , the sealing ring 151 includes a first sealing portion 151a and a second sealing portion 151b.

[0109] Exemplarily, the first sealing portion 151a and the second sealing portion 151b are of an integrally formed structure.

[0110] As shown in Figure 6a and Figure 6b , the first sealing portion 151a is farther from the enclosed space Q than the second sealing portion 151b; the second sealing portion 151b is located at one end of the first sealing portion 151a close to the second protruding portion 122b and is connected to the surface of the first sealing portion 151a facing away from the first main body portion 112a; the surface of the second sealing portion 151b facing away from the second protruding portion 122b forms a dihedral angle with the surface of the first sealing portion 151a facing away from the first main body portion 112a. The surface of the second sealing portion 151b close to the second protruding portion 122b is coplanar with the surface of the first sealing portion 151a close to the second protruding portion 122b.

[0111] Exemplarily, the first sealing portion 151a is of a wedge-shaped structure, and the first sealing portion 151a and the second sealing portion 151b are connected to form a groove facing the bottom shell 121.

[0112] Figure 10b is a cross-sectional view of the expansion frame. As shown in Figure 10b , the expansion frame 152 includes a first squeezing portion 152a and a second squeezing portion 152b.

[0113] Exemplarily, the first squeezing portion 152a and the second squeezing portion 152b are of an integrally formed structure.

[0114] As shown in Figure 6a and Figure 6b , the second squeezing portion 152b is closer to the second protruding portion 122b than the first squeezing portion 152a; the surface of the second squeezing portion 152b close to the first main body portion 112a forms a dihedral angle with the surface of the first squeezing portion 152a close to the first main body portion 112a.

[0115] Exemplarily, the second extrusion portion 152 b is a wedge-shaped structure, and there is a sloped gap between the second extrusion portion 152 b and the first main body portion 112 a .

[0116] When the sealing structure 15 is in a compressed state, the second extrusion portion 152b abuts against the second sealing portion 151b. At this time, the second extrusion portion 152b is pressed into the groove formed between the first sealing portion 151a and the second sealing portion 151b, further extruding the first sealing portion 151a closer to the first main body portion 112a, and the interaction of forces causes the second extrusion portion 152b to be closer to the second main body portion 122a, thereby achieving a sealing effect, and the wedge-shaped structure is tightly matched to ensure the sealing effect.

[0117] Of course, in addition to the above-mentioned wedge-shaped structure, the sealing ring 151 and the expansion frame 152 can also be in other forms, as long as the sealing ring 151 is deformed by extrusion and the gap between the antenna cover 11 and the outer shell 12 is fully filled.

[0118] It should be noted that the more the number of first screws 16 arranged relatively, the better the sealing and tightening effect, but the relative assembly complexity and cost are higher, so the number and spacing of the first screws 16 can be arranged by comprehensively considering various factors and experience. The present disclosure sets 8 first screws 16, but in actual use, they can also be increased or decreased according to the actual structural size to ensure the sealing stability.

[0119] Figure 11a A schematic diagram of an initial state of another sealing structure provided by an embodiment of the present disclosure before being compressed. Figure 11b This is a schematic diagram of another sealing structure provided by an embodiment of the present disclosure in a deformed state after compression. Here, only the antenna cover 11 and the outer shell 12 are illustrated. For the actual structure diagram, please refer to the above Figure 1 ~9 shown.

[0120] In some embodiments, Figure 11a and Figure 11b As shown, Figure 6a and Figure 6b The difference between the middle sealing ring 151 is that the sealing ring 151 is not a wedge-shaped structure, and its cross section is a regular rectangle; Figure 6a and Figure 6b The difference between the expansion frame 152 and the expansion frame 152 is that the expansion frame 152 is not a wedge-shaped structure, and its cross section is a regular rectangle.

[0121] like Figure 11a and Figure 11b As shown, the sealing ring 151 is bonded to the surface of the second protrusion 122b close to the bottom shell 121; the expansion frame 152 is arranged on the side of the sealing ring 151 away from the second protrusion 122b.

[0122] During the sealing process, under the push of the first screw 16, the first stud is continuously screwed into the first threaded hole, driving the first screw head 161 to continuously press against the expansion frame 152. The expansion frame 152 is continuously pressed, further squeezing the sealing ring 151. The sealing ring 151 undergoes elastic deformation, causing it to tightly adhere to the first side wall 112 and the second side wall 122, thereby achieving the sealing effect.

[0123] In addition, the embodiment of the present disclosure further provides an antenna device, which includes the antenna packaging structure of any one of the above embodiments and an antenna disposed in the enclosed space Q of the antenna packaging structure.

[0124] In some examples, the antenna in the antenna device further includes a transceiver unit, a radio frequency transceiver, a signal amplifier, a power amplifier, and a filtering unit. The antenna device serves as a communication device, and the antenna in the communication device can serve as a transmitting antenna or a receiving antenna. Among them, the transceiver unit may include a baseband and a receiving end. The baseband provides signals of at least one frequency band, such as providing 2G signals, 3G signals, 4G signals, 5G signals, etc., and sends the signals of at least one frequency band to the radio frequency transceiver. When the antenna in the communication device receives a signal, it can be transmitted to the receiving end in the transceiver unit after being processed by the filtering unit, the power amplifier, the signal amplifier, and the radio frequency transceiver. The receiving end can be, for example, an intelligent gateway or the like.

[0125] Furthermore, the radio frequency transceiver is connected to the transceiver unit and is used to modulate the signal sent by the transceiver unit or to demodulate the signal received by the antenna and then transmit it to the transceiver unit. Specifically, the radio frequency transceiver may include a transmitting circuit, a receiving circuit, a modulation circuit, and a demodulation circuit. After the transmitting circuit receives various types of signals provided by the baseband, the modulation circuit can modulate the various types of signals provided by the baseband and then send them to the antenna. The antenna receives the signal and transmits it to the receiving circuit of the radio frequency transceiver. The receiving circuit transmits the signal to the demodulation circuit, and the demodulation circuit demodulates the signal and then transmits it to the receiving end.

[0126] Further, the radio frequency transceiver is connected to the signal amplifier and the power amplifier. The signal amplifier and the power amplifier are then connected to the filtering unit, and the filtering unit is connected to at least one antenna. During the process of the communication device transmitting a signal, the signal amplifier is used to improve the signal-to-noise ratio of the signal output by the radio frequency transceiver and then transmit it to the filtering unit; the power amplifier is used to amplify the power of the signal output by the radio frequency transceiver and then transmit it to the filtering unit; the filtering unit may specifically include a duplexer and a filtering circuit. The filtering unit combines the signals output by the signal amplifier and the power amplifier, filters out the clutter, and then transmits the signals to the antenna, and the antenna radiates the signals. During the process of the communication device receiving a signal, after the antenna receives the signal, it transmits the signal to the filtering unit. The filtering unit filters out the clutter of the signal received by the antenna and then transmits the signal to the signal amplifier and the power amplifier. The signal amplifier amplifies the signal received by the antenna to increase the signal-to-noise ratio of the signal; the power amplifier amplifies the power of the signal received by the antenna. The signal received by the antenna is processed by the power amplifier and the signal amplifier and then transmitted to the radio frequency transceiver, and the radio frequency transceiver then transmits it to the transceiver unit.

[0127] In some examples, the signal amplifier may include various types of signal amplifiers, such as a low-noise amplifier, which is not limited herein.

[0128] In some examples, the antenna provided by the embodiments of the present disclosure further includes a power management unit. The power management unit is connected to the power amplifier and provides the voltage for amplifying the signal to the power amplifier.

[0129] Other essential components of the antenna device should be understood by those of ordinary skill in the art and will not be elaborated herein, nor should it be considered as a limitation to the present disclosure.

[0130] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principles of the present disclosure. However, the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present disclosure, and these modifications and improvements are also regarded as the protection scope of the present disclosure.
