In some embodiments, referring to fig. 3, fig. 3 is a schematic diagram of a first structure of an antenna assembly 20 provided by an embodiment of the present application.
The antenna assembly 20 includes a first antenna 21, a second antenna 22, and an isolation structure 23. The first free end 210 of the first antenna 21 is disposed opposite to the second free end 220 of the second antenna 22. The first free end 210 and the second free end 220 form a first gap 27 therebetween. The isolation structure 23 is electromagnetically coupled to at least one of the first antenna 21 and the second antenna 22, and the isolation structure 23 is grounded.
The first antenna 21 may also transmit or receive the first positioning signal. Or to simultaneously transmit and receive the first positioning signal. The first antenna 21 may transmit or receive a first radio frequency signal. Or to simultaneously transmit and receive the first radio frequency signal. Wherein the first antenna may be a three-in-one antenna. The first radio frequency signal may be a Global Positioning System (GPS) signal in an L1 frequency band, and a fifth-generation Wi-Fi signal in a 2.4GHz (gigahertz) frequency band and a 5GHz frequency band (WiFi 2.4G and WiFi5G for short). Wherein the frequency range of the L1 band may be 1575.42 ± 1.023MHz (megahertz). The first positioning signal comprises a GPS signal in an L1 frequency band. The first radio frequency signal comprises a low frequency radio frequency signal, an intermediate frequency radio frequency signal and a high frequency radio frequency signal. Wherein, the frequency of the low-frequency radio frequency signal can comprise 699MHz to 960MHz, the frequency of the intermediate-frequency radio frequency signal can comprise 1710MHz to 2170MHz, and the frequency of the high-frequency radio frequency signal can comprise 2300MHz to 2690 MHz. In addition, the first radio frequency signal comprises a WiFi signal of a 2.4GHz frequency band and a WiFi signal of a 5GHz frequency band.
The second antenna 22 is used for transmitting a second positioning signal or a second radio frequency signal. The second antenna 22 may be a two-in-one antenna. The two-in-one antenna may include a GPS antenna of an L5 frequency band and a fifth generation mobile communication network (5G) antenna of a Sub6G frequency band. Wherein the frequency range of the L5 frequency band may be 1176.45 ± 1.023 MHz. The frequency band of Sub6G may be 3.4GHz to 3.6 GHz. In some embodiments, the second positioning signal may comprise a GPS signal in the L5 frequency band. The second radio frequency signal may include a Sub6G band 5G radio frequency signal.
In addition, the second antenna 22 transmits the second positioning signal or the second radio frequency signal by time division multiplexing. And a time division multiplexing method is adopted for the 5G antenna of the Sub6G frequency band, so that the second antenna normally transmits GPS signals or 5G signals. Firstly, a time interval is selected from time intervals of 5G signals transmitted by a 5G antenna, and the time interval is used as the time interval of GPS signals transmitted by a GPS antenna. And when the 5G antenna transmits the 5G signal to the time gap, switching to the GPS antenna to transmit the GPS signal.
In some embodiments, the first free end 210 of the first antenna 21 is disposed opposite the second free end 220 of the second antenna 22. I.e. the strongest rf signal transmitted by the first free end 210 of the first antenna 21 is located opposite to the strongest rf signal transmitted by the second free end 220 of the second antenna 22. Secondly, since the first free end 210 of the first antenna 21 is disposed opposite to the second free end 220 of the second antenna 22, the electromagnetic coupling between the two antennas affects the first antenna 21 to normally transmit the first radio frequency signal and the second antenna 22 to normally transmit the second radio frequency signal. And therefore, the stability of the signals transmitted by the first and second antennas 21 and 22 is reduced. An isolation structure 23 is provided to allow part of the currents of the first antenna 21 and the second antenna 22 to be derived from the isolation structure 23, thereby ensuring the normal output of the rf signals of the first antenna 21 and the second antenna 22. I.e. the currents of the first antenna 21 and the second antenna 22 are led out from the feed point through the isolation structure 23. The isolation between the first antenna 21 and the second antenna 22 is thus improved.

The BOX can be a speaker.
In addition, the motor may push the camera module 28 out of the interior of the electronic device, or push the camera module 28 into the interior of the electronic device. The camera module 28 may also be disposed on a chute disposed on the housing. The camera module 28 can slide in the sliding groove. The camera module 28 may be a front camera, a rear camera, or a combination of the front camera and the rear camera.
In addition, the antenna carrier 25 is provided with a ground 30. The first antenna 21 and the second antenna 22 are disposed at the edge of the whole machine ground 30. A second gap 301 is formed between the first antenna 21 and the ground 30. The second portion of the second antenna 22 forms a third gap 302 with the overall ground 30. The second portion of the second antenna 22 is electrically connected to the overall ground 30. Wherein the overall ground 30 is used to ground the first antenna 21 and the second antenna 22. A third feed point 29 is provided at the second gap 301. The third ground feed point 29 is electrically connected to the complete machine ground 30 and the first antenna 21. The third feed point is used to ground the first antenna 21.
Referring to fig. 4, fig. 4 is a schematic diagram of a second structure of the antenna assembly 20 according to the embodiment of the present application.
In some embodiments, the antenna assembly 20 further includes a matching circuit 24, and a first end 241 of the matching circuit 24 is connected to the second antenna 22. The second terminal 242 of the matching circuit 24 is connected to ground. The matching circuit 24 is configured to adjust an operating frequency band of the second antenna 22, so that the second antenna 22 is suitable for transmitting the second positioning signal or the second radio frequency signal.
In some embodiments, antenna assembly 20 includes an antenna carrier 25 and a metal bezel 26. The metal frame 26 is formed at the periphery of the antenna carrier 25. For example, the metal frame 26 may be disposed around the periphery of the antenna carrier 25. The material of the metal frame 26 may include aluminum alloy, magnesium alloy, and the like. In some embodiments, the antenna carrier 25 may be the bezel 13 of the electronic device 100. The first antenna 21 and the second antenna 22 are both arranged on the antenna carrier 25.
Referring to fig. 5, fig. 5 is a schematic diagram of a third structure of the antenna assembly 20 according to the embodiment of the present application.
The second antenna 22 comprises first and second spaced apart feed points 221 and 222. The matching circuit 24 comprises a switch. The first end 241 of the switch 24 includes a first input port 2411 and a second input port 2412. The first input port 2411 is connected to the first feed point 221 and the second input port 2412 is connected to the second feed point 222. The switch 24 can be switched to the first input port 2411 to be conducted with the second end 242 of the switch 24 or switched to the second input port 2412 to be conducted with the second end 242
If the feeding point of the 5G antenna in the second antenna 22 is the first feeding point 221, the feeding point of the GPS antenna is the second feeding point 222. When the 5G antenna transmits a 5G signal and the transmitted 5G signal is about to reach the preset time gap, then the switch 24 disconnects the first input port 2411 from the first feed point 221 and then connects the second input port 2412 to the second feed point 222, thereby allowing the GPS antenna and the 5G antenna to coexist. Therefore, the GPS antenna is not influenced to transmit GPS signals, and the 5G antenna transmits 5G signals. The preset time gap is a time gap of the GPS antenna for transmitting the GPS signal. On the contrary, if the feeding point of the GPS antenna in the second antenna 22 is the first feeding point 221, the feeding point of the 5G antenna is the second feeding point 222. When the 5G antenna transmission 5G is about to reach the predetermined time gap, then the switch 24 disconnects the second input port 2412 from the second feed point 222 and then connects the first input port 2411 to the first feed point 221, thereby allowing the GPS antenna to coexist with the 5G antenna. Therefore, the GPS antenna is not influenced to transmit GPS signals, and the 5G antenna transmits 5G signals.
In some embodiments, the isolation structure 23 includes a metal stub disposed on the antenna carrier 25. The metal branch is disposed between the first antenna 21 and the second antenna 22. Wherein the metal branch can be made into any shape. I.e. including regular and irregular shapes. Or the metal branch joint formed by splicing two sub-metal branch joints with unequal lengths. Or two sub-metal branches with proportional area are spliced into a metal branch. For example, the area ratio may be 1:1, 1:2, or 3:5, etc. And will not be described in detail herein.
Referring to fig. 6, fig. 6 is a fourth structural schematic diagram of the antenna assembly 20 according to the embodiment of the present application.
Wherein the isolation structure 23 comprises a capacitor, and the capacitor is connected to the second antenna 22. Wherein the capacitor can be an adjustable capacitor or a fixed value capacitor. When the first antenna 21 and the second antenna 22 generate electromagnetic coupling, that is, the first rf signal of the first antenna 21 and the second rf signal of the second antenna 22 interfere with each other, and the first rf signal of the first antenna 21 and the second rf signal of the second antenna 22 cannot be normally output, the adjustable capacitor is adjusted to a fixed value or a fixed value capacitor is selected to be connected to the second antenna 22. The fixed value capacitance can improve the stability of the signals transmitted by the first antenna 21 and the second antenna 22, so that the first antenna 21 is protected from the radio frequency signal interference of the second antenna 22. Then, although the capacitance of the selected fixed value prevents the first antenna 21 from interfering with the rf signal of the second antenna 22, the stability of the transmission signal of the second antenna 22 is reduced. Therefore, the length of the second antenna 22 is shortened or is selected to be suitable for the second antenna 22 to output the rf signal normally, so as to improve the stability of the signal transmission of the second antenna 22. The isolation between the first antenna 21 and the second antenna 22 is thus improved. In addition, the capacitor is grounded. Wherein the fixed value of the capacitor or the capacitance value thereof is selected according to the condition that the first antenna 21 can be protected from interference.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a fifth antenna assembly 20 according to an embodiment of the present application.
The antenna assembly 20 further comprises a first feed 31 and a second feed 32, the first feed 31 and the second feed 32 may be provided on a circuit board of the electronic device 100.
The first feed 31 is used to generate a first positioning signal. The first feed 31 is connected to the first antenna 21 of the antenna assembly 20. Thus, the first feed 31 can feed the first positioning signal to the first antenna 21. The first positioning signal may be a GPS signal in the L1 frequency band.
The first feed 31 may also be used to generate a first radio frequency signal. The first feed 31 is connected to the first antenna 21 of the antenna assembly 20. Thus, the first feed 31 may feed the first radio frequency signal to the first antenna 21. The WiFi signal may include a WiFi signal of a 5G frequency band and a WiFi signal of a 2.4G frequency band.
The second feed 32 is used to generate a second radio frequency signal. The second feed 32 is connected to the second antenna 22 of the antenna assembly 20. The second feed 32 may thus feed the second radio frequency signal to the second antenna 22. The second radio frequency signal may be a Sub6G band 5G signal.
The second feed 32 is also used to generate a second positioning signal. The second feed 32 is connected to the second antenna 22 of the antenna assembly 20. The second feed 32 may thereby feed the second antenna 22 with the second positioning signal. Wherein the second positioning signal may be a GPS signal of L5 frequency band.
