[0051] A communication system needs to cover multiple frequency bands to implement different communication services, and a multi-band antenna 100 can provide good performance at different frequency bands.

[0052] Based on this, the embodiments of this application provide an antenna 100. Exemplarily, the antenna 100 in this application is an external wifi antenna 100.

[0053] In some embodiments, refer to Figure 1, the antenna 100 includes a radiator 102, which refers to the part for transmitting or receiving signals. Specifically, the radiator 102 is the component in the antenna 100 structure that generates electromagnetic waves. An electromagnetic field is formed by the current in the radiator 102, thereby generating radiation. The radiator 102 is the part in the antenna 100 that actually conducts signal transmission or reception, and is the most critical part in the antenna 100 structure.

[0054] Exemplarily, the operating frequency of the radiator 102 is at a quarter of the wavelength corresponding to the operating frequency and near the corresponding multiple frequencies.

[0055] In some embodiments, referring to Figure 1 , the antenna 100 in the present application further includes a reference ground 101, and the reference ground 101 is grounded.

[0056] Further, in order to achieve a good grounding effect, the reference ground 101 is a metal disk.

[0057] The antenna 100 in the present application further includes a feeding structure 103 and a grounding member 104. The feeding structure 103 includes a signal transmission part and a grounding part. The signal transmission part is electrically connected to the radiator 102, and the grounding part is electrically connected to the reference ground 101. One end of the grounding member 104 is electrically connected to the radiator 102, and the other end of the grounding member 104 is electrically connected to the reference ground 101.

[0058] It can be understood that the signal transmission part of the feeding structure 103 is responsible for delivering the received signal to the radiator 102. In this way, the electrical signal generated by the signal source can be effectively transmitted to the radiator 102 through the feeding structure 103, so that the radiator 102 can radiate or receive the signal.

[0059] Exemplarily, the signal transmission part of the feeding structure 103 is used to receive wifi signals.

[0060] During the operation of the antenna 100 in the present application, the radiator 102 itself can operate in the first operating frequency band. By electrically connecting the radiator 102 to the grounding member 104 to form a three-dimensional structure, the antenna 100 in the present application can also operate in the second operating frequency band.

[0061] For ease of understanding, the radiator 102 itself is an antenna 100 with a single oscillator. After the radiator 102 is electrically connected to the grounding member 104, a three-dimensional pifa antenna 100 is formed. In this way, the antenna 100 in the present application can operate both in the first operating frequency band corresponding to the single-oscillator antenna 100 and in the second operating frequency band corresponding to the pifa antenna 100.

[0062] During a thunderstorm, lightning may enter a building or equipment system through the metal structure of antenna 100, causing damage to equipment or fires and other hazards.

[0063] However, the grounding member 104 in this application can provide a good grounding system for antenna 100. Through the grounding member 104, the radiator 102 is connected to the reference ground 101, and the grounding portion of the feeding structure 103 is connected to the reference ground 101. In this way, when lightning strikes antenna 100, the reference ground 101 can diffuse and absorb the energy of the lightning, thereby reducing the impact of lightning on antenna 100. Thus, antenna 100 in this application also has a good lightning protection effect.

[0064] In some embodiments, referring to Figure 1 and combining with Figure 2 , antenna 100 in this application further includes a base 105. The reference ground 101 is provided on the base 105, and the radiator 102 is provided on the side of the reference ground 101 facing away from the base 105.

[0065] Exemplarily, the base 105 is a suction cup.

[0066] Exemplarily, the base 105 is a counterweight.

[0067] In this way, the base 105 can provide a strong supporting force for the entire structure of antenna 100, so that antenna 100 can work more stably.

[0068] In some embodiments, referring to Figure 4 , a first avoidance hole 1011 is provided at a position on the reference ground 101 opposite to the radiator 102. The base 105 is provided with a mounting hole 1051. One end of the mounting hole 1051 is opposite to and communicates with the first avoidance hole 1011, and the feeding structure 103 is accommodated in the first avoidance hole 1011 and the mounting hole 1051.

[0069] On the one hand, accommodating the feeding structure 103 in the mounting hole 1051 can effectively reduce the overall volume of antenna 100. On the other hand, compared with the feeding structure 103 directly exposed outside, placing the feeding structure 103 in the mounting hole 1051 can also form a good protection for the feeding structure 103, reduce energy loss, and improve signal transmission efficiency.

[0070] It can be understood that the feeding structure 103 is directly connected to the radiator 102 through the first avoidance hole 1011, which can reduce the layout route of the feeding structure 103. At the same time, the first avoidance hole 1011 also plays a role in receiving and fixing the feeding structure 103.

[0071] In some embodiments, referring to Figure 3 and combining with Figure 4, the mounting hole 1051 includes a first mounting hole 10511 and a second mounting hole section 10512. The first mounting hole 10511 includes opposite first and second ends. The first end faces and communicates with the first avoidance hole 1011. From the first end to the second end, the first mounting hole 10511 extends away from the radiator 102.

[0072] One end of the second mounting hole section 10512 is connected to the second end. The other end of the second mounting hole section 10512 is located on the side wall of the base 105. The extending direction of the second mounting hole section 10512 intersects or is perpendicular to the extending direction of the first mounting hole 10511.

[0073] In this way, the present application provides two ways to arrange the feeding structure 103. The feeding structure 103 can adapt to different installation conditions, thereby further expanding the applicable range of the antenna 100.

[0074] In some embodiments, for the convenience of installation, refer to Figure 3 , the second end of the first mounting hole 10511 and the second mounting hole section 10512 penetrate through the surface of the base 105 facing away from the radiator 102.

[0075] It can be understood that the surface of the base 105 facing away from the radiator 102 forms an operation opening. The position of the feeding structure 103 can be adjusted through the operation opening, which is not only convenient for the installation and position adjustment of the feeding structure 103, but also convenient for subsequent maintenance.

[0076] In some embodiments, refer to Figure 4 , the feeding structure 103 in the present application includes a coaxial cable 1031.

[0077] The coaxial cable 1031 is used to transmit signals. One end of the coaxial cable 1031 is connected to the radiator 102, and the other end of the coaxial cable 1031 is connected to a wifi signal source.

[0078] In some embodiments, refer to Figure 4 , the coaxial cable 1031 in the present application includes an inner conductor 10311, a dielectric layer 10313, and an outer conductor 10312. The dielectric layer 10313 is attached to the inner conductor 10311, and the outer conductor 10312 is attached to the dielectric layer 10313.

[0079] Among them, the inner conductor 10311 forms a signal transmission part. The inner conductor 10311 is electrically connected to the feeding structure 103. The outer conductor 10312 forms a grounding part. The dielectric layer 10313 located between the inner conductor 10311 and the outer conductor 10312 is an insulating layer.

[0080] Further, to facilitate the connection between the inner conductor 10311 and the radiator 102, a connection portion 10221 is formed on one side of the center feeding portion 1022 close to the signal transmission portion. Specifically, a connection portion 10221 is formed on one side of the center feeding portion 1022 close to the inner conductor 10311. The connection portion 10221 provides an accurate installation position for the inner conductor 10311.

[0081] Exemplarily, the signal transmission portion is welded to the radiator 102, that is, the inner conductor 10311 is welded to the radiator 102.

[0082] Further, to facilitate the filling of solder, a plurality of reserved holes 10222 are provided in the connection portion 10221. In this way, solder can be filled into the gap between the inner conductor 10311 and the radiator 102 through the reserved holes 10222.

[0083] And to facilitate the operation, a plurality of reserved holes 10222 are provided on the side wall of the connection portion 10221.

[0084] In some embodiments, the present application further includes a fixing piece 107. The fixing piece 107 includes a first connection section 1071 and a second connection section 1072. The first connection section 1071 is connected to the outer conductor 10312, and the second connection section 1072 is connected to the reference ground 101.

[0085] Further, the first connection section 1071 is welded to the outer conductor 10312, and the second connection section 1072 is welded to the outer conductor 10312.

[0086] Exemplarily, soldering is used for welding in the present application.

[0087] Further, there are a plurality of fixing pieces 107. The plurality of fixing pieces 107 are arranged around the outer conductor 10312 for one week. In this way, the fixing pieces 107 can play a good fixing role for the coaxial line 1031 and solve the problem of the shaking of the coaxial line 1031 caused by errors.

[0088] In some embodiments, referring to Figure 4 , the radiator 102 includes a radiation body 1021, a center feeding portion 1022, and an insulating layer 1023. A receiving groove 10211 recessed away from the reference ground 101 is provided on the surface of the radiation body 1021 facing the reference ground 101. The grounding member 104 is connected between the radiation body 1021 and the reference ground 101. The center feeding portion 1022 is received in the receiving groove 10211. The center feeding portion 1022 is electrically connected to the signal transmission portion. The insulating layer 1023 is provided between the center feeding portion 1022 and the inner wall surface of the receiving groove 10211.

[0089] Exemplarily, the insulating layer 1023 is a plastic film, and the plastic film can block the lightning strike between the center feeding part 1022 and the radiation body 1021.

[0090] Furthermore, the insulating layer 1023 includes a first limiting part 10231 and a second limiting part 10232. The first limiting part 10231 is located in the accommodating groove 10211, and the second limiting part 10232 is located on the side of the radiation body 1021 close to the coaxial line 1031. The first limiting part 10231 is used to fix the center feeding part 1022 in the accommodating groove 10211, and the second limiting part 10232 is used to fix the coaxial line 1031 at the connection position between the coaxial line 1031 and the radiation body 1021.

[0091] In some embodiments, referring to Figure 5 and combining with Figure 4 , the grounding member 104 includes a first grounding section 1041 and a second grounding section 1042. The first grounding section 1041 includes a third end 1041a and a fourth end 1041b. The third end 1041a is electrically connected to the radiation body 1021. From the third end 1041a to the fourth end 1041b, the first grounding section 1041 extends in a direction away from the accommodating groove 10211. One end of the second grounding section 1042 is connected to the fourth end 1041b, and the other end of the second grounding section 1042 is connected to the reference ground 101. The extending direction of the second grounding section 1042 intersects or is perpendicular to the extending direction of the first grounding section 1041.

[0092] In this way, by setting the grounding member 104 as the first grounding section 1041 and the second grounding section 1042 that form an included angle, the length of the grounding member 104 can be increased, so that the antenna 100 system is closer to the ideal length in terms of electrical length, which helps to improve the resonance effect and performance of the antenna 100 system.

[0093] Exemplarily, the grounding member 104 is a metal wire.

[0094] In some embodiments, referring to Figure 2 and combining with Figure 4 , the embodiment of the present application further includes a conductive sheet 106, and the conductive sheet 106 is arranged on the grounding member 104.

[0095] By adding the conductive sheet 106 in the present application, a resonance frequency at a higher frequency can be formed for the antenna 100, and the working frequency band of the antenna 100 can be expanded. Therefore, the antenna 100 in the present application can work in the third working frequency band.

[0096] In some embodiments, referring to Figure 5 and combining with Figure 4, To achieve a stable signal transmission effect, the conductive sheet 106 is disposed on the second grounding section 1042, and the central axis of the conductive sheet 106 coincides with the central axis of the second grounding section 1042. The conductive sheet 106 is in electrical contact with the first grounding section 1041.

[0097] Exemplarily, the conductive sheet 106 is a metal disc, the metal disc is sleeved on the second grounding section 1042, and is in contact with the first grounding section 1041.

[0098] In some embodiments, referring to Figure 5 , to form a protection and a good fixing effect on the radiator 102 (not shown in the figure), the present application further includes a first housing 108. The first housing 108 is provided with a first accommodation cavity and a first opening communicating the first accommodation cavity with the outside. The radiator 102 is accommodated in the first accommodation cavity, the first opening faces the reference ground 101, and the first housing 108 is connected to the reference ground 101.

[0099] To enable the grounding member 104 to be electrically connected to the radiator 102, a second avoidance hole 1081 communicating with the first accommodation cavity is provided on the side wall of the first housing 108, and a part of the grounding member 104 is accommodated in the second avoidance hole 1081.

[0100] In some embodiments, referring to Figure 6 , the present application further includes a second housing 109. The second housing 109 is provided with a second accommodation cavity, and the reference ground 101, the radiator 102, the feeding structure 103, the grounding member 104 and the conductive sheet 106 are accommodated in the second accommodation cavity.

[0101] In this way, the second housing 109 can form a good protection for the entire antenna 100 structure, effectively preventing dust, particulate matter and liquid from entering the inside of the antenna 100, keeping the antenna 100 clean and operating normally, and reducing damage and failures caused by dust and liquid.

[0102] At the same time, the second housing 109 can also improve the aesthetics of the antenna 100, thereby enhancing the user experience.

[0103] Further, to avoid the second housing 109 affecting the wiring of the coaxial cable 1031, a third avoidance hole 1091 through which the coaxial cable 1031 can pass is provided on the side wall of the second housing 109.

[0104] In daily applications, exemplarily, the first operating frequency band is 2.4 GHz, the second operating frequency band is 5 GHz, and the third operating frequency band is 6 GHz.

[0105] The following describes the specific working conditions of the present application at different operating frequency bands. Refer to Figures 7 - 14, the abscissa in the figure represents the operating frequency band of the antenna 100, with the unit of GHz, and the ordinate in the figure represents the total efficiency of the antenna 100, with the unit of dB.

[0106] Specifically, refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , these four figures correspond to Figure 1 some relevant parameters of the antenna 100 shown, that is, the antenna 100 without the conductive sheet 106 added.

[0107] Among them, Figure 7 and Figure 8 are the return losses corresponding to the 2.4G frequency band, Figure 8 corresponds to the efficiency of the antenna 100 in the 2.4G frequency band; Figure 9 is the return loss of the antenna 100 in the 5GHz frequency band, Figure 10 is the efficiency corresponding to the antenna 100 in the 5GHz frequency band.

[0108] It can be seen from the above four figures that Figure 1 the antenna 100 shown can operate in the 2.4GHz frequency band and the 5GHz frequency band, enabling the corresponding device to switch between different frequency bands. It can be understood that Figure 1 the antenna 100 shown improves the compatibility of the antenna 100 so that the antenna 100 can be applied to more devices.

[0109] In some embodiments, after the conductive sheet 106 is added to the antenna 100 in the present application, the antenna 100 shown in Figure 2 is formed.
