In this embodiment, when the material of the housing 112 is a conductive material, the housing 112 may be used as an antenna radiator for receiving and transmitting electromagnetic wave signals in the second frequency band according to the second signal.
It should be noted that, in the related art, the cable 11 in the electronic device is generally used to transmit only one antenna signal, i.e., the first signal. It can be appreciated that in this embodiment, the inner core 111 is configured to transmit the first signal, the outer shell 112 is configured to transmit the second signal, and the electromagnetic wave signal in the first frequency band transmitted and received according to the first signal is different from the electromagnetic wave signal in the second frequency band transmitted and received according to the second signal, so that the first signal and the second signal are respectively transmitted on the same cable 11, coexistence of different antenna signals is achieved, and design space of an antenna is saved.

The inner core 111, the outer shell 112 and the insulating layer 113 are described above, and will not be described again. In this embodiment, the cable 11 further includes a protective layer 114, where the protective layer 114 is wrapped around the outer shell 112 and is used for protecting the outer shell 112, the insulating layer 113 and the inner core 111.
The material of the protective layer 114 is generally a relatively strong and nonconductive material, so that the protective layer 114 can protect the outer shell 112, the insulating layer 113 and the inner core 111. It is understood that the material of the protection layer 114 is not limited in the present application. For example, the material of the protection layer 114 may be, but is not limited to, rubber, plastic, etc.

The antenna assembly 1, including the capacitor 12, may be incorporated into the antenna assembly 1 of any of the previous embodiments, as described in detail below.
In one possible embodiment, the antenna assembly 1 includes an inner core 111, an outer shell 112, an insulating layer 113, and a capacitor 12. The inner core 111, the outer shell 112 and the insulating layer 113 are described above, and will not be described again.
In another possible embodiment, the antenna assembly 1 includes an inner core 111, an outer shell 112, an insulating layer 11, a protective layer 114, and a capacitor 12. The inner core 111, the outer shell 112, the insulating layer 113 and the protective layer 114 are described above, and will not be described again.
Since the capacitor 12 has the characteristic of passing high frequency and low frequency, the electromagnetic wave signal of the first frequency band with the larger frequency can be grounded through the capacitor 12, and the electromagnetic wave signal of the second frequency band with the smaller frequency is isolated relative to the capacitor 12. Therefore, the antenna assembly 1 provided in this embodiment achieves the purpose that the electromagnetic wave signals of the first frequency band and the electromagnetic wave signals of the second frequency band do not interfere with each other by adding the capacitor 12.
It can be understood that, by having a certain relationship between the frequency of the electromagnetic wave signal of the capacitor 12 and the capacitance of the capacitor 12, the capacitance of the capacitor 12 can be set according to practical situations, and the frequency of the electromagnetic wave signal passing through the capacitor 12 can be changed, so as to achieve the purpose of controlling the electromagnetic wave signals of different first frequency bands to be grounded through the capacitor 12. The capacitance of the capacitor will be described later in connection with the magnitudes of the first frequency band and the second frequency band.

In one possible embodiment, the antenna assembly 1 includes an inner core 111, an outer shell 112, an insulating layer 113, and a capacitor 12, and the outer shell has a plurality of connection points 112a arranged at intervals. The inner core 111, the outer shell 112 and the insulating layer 113 are described above, and will not be described again.

Specifically, in this embodiment, the capacitance value of each capacitor 12 is the same. In other possible embodiments, for example, when the housing 112 is further configured to transmit an electromagnetic wave signal in a third frequency band, and the frequency of the electromagnetic wave signal in the third frequency band is different from the frequency of the electromagnetic wave signal in the second frequency band, the capacitance value of each capacitor 12 may be different, so that a portion of the capacitors 12 may also block the electromagnetic wave signal in the third frequency band, so that the electromagnetic wave signal in the third frequency band and the electromagnetic wave signal in the first frequency band do not interfere with each other.
In one possible embodiment, please refer to fig. 7, fig. 7 is a schematic circuit diagram of an antenna assembly according to another embodiment of the present application. The antenna component 1 comprises an inner core 111, a shell 112, an insulating layer 113 and a capacitor 12, wherein the shell is provided with a plurality of connecting points 112a which are arranged at intervals, and the antenna component 1 also comprises a feed source 13 and an inductor 14. The inner core 111, the outer shell 112, the insulating layer 113 and the capacitor 12 are described above, and will not be described herein. The feed 13 is used to generate the second signal.

The housing 112 has a ground point 112b, the ground point 112b being directly grounded. The feed 13, the housing 112, and the ground point 112b form a signal transmission loop of the second signal.
Specifically, the housing 112 is directly grounded through the ground point 112b, and the second signal can be grounded through the ground point 112 b. In the signal transmission loop of the second signal, the inductor 14 has the characteristic of passing low frequency and high frequency, so that the signal transmission loop of the second signal isolates the electromagnetic wave signal of the first frequency band with larger frequency, thereby realizing that the first signal and the second signal are not interfered with each other, i.e. the electromagnetic wave signal of the first frequency band and the electromagnetic wave signal of the second frequency band are not interfered with each other.
It can be understood that, by having a certain relationship between the frequency of the electromagnetic wave signal of the inductor 14 and the inductance of the inductor 14, the inductance of the inductor 14 can be set according to the actual situation, and the frequency of the electromagnetic wave signal passing through the inductor 14 can be changed, so as to achieve the purpose of controlling the electromagnetic wave signals of different second frequency bands to pass through the inductor 14. The inductance of the inductor will be described later in connection with the magnitudes of the first frequency band and the second frequency band.
In one possible implementation, referring again to fig. 7, the end 112c of the inductor 14 electrically connected to the housing 112 is located at one end of the cable 11, and the ground point 112b is located at the other end of the cable 11.
Specifically, in this embodiment, since the housing 112 is used as an antenna radiator of the electromagnetic wave signal in the second frequency band, the end 112c of the inductor 14 electrically connected to the housing 112 is located at one end of the cable 11, and the ground point 112b is located at the other end of the cable 11, so that the path of the second signal transmitted on the housing 112 can be made longer.
In one possible embodiment, please refer to fig. 8, fig. 8 is a schematic circuit diagram of an antenna assembly according to another embodiment of the present application. One end of the inductor 14 is electrically connected to one connection point 112a at the end, and the remaining connection point 112a is located between the one connection point 112a at the end and the ground point 112 b.
Specifically, as shown in fig. 8, the arrangement mode makes the transmission path of the second signal on the housing 112 longest, so that the length of the antenna radiator formed by the housing 112 is longest, thereby achieving the purpose of supporting the electromagnetic wave signal of the second frequency band with wider frequency band.
It will be appreciated that in other possible embodiments, the end 112c of the inductor 14 electrically connected to the housing 112 may be located at another location of the housing 112, so long as the signal transmission loop of the second signal formed by the feed 13, the housing 112, and the ground point 112b is not affected, which is not limited by the present application.

Specifically, the ground pole 151 is the total ground on the circuit board 15.

The ground point 112b is electrically connected to the ground electrode 151 such that the ground point 112b is directly grounded, thereby forming a signal transmission loop of the second signal.

The electromagnetic wave signal of the second frequency band may be a near field communication (Near Field Communication, NFC) signal, and the frequency of the electromagnetic wave signal of the second frequency band is 13.56MHz. Since the electromagnetic wave signal of less than 100MHz belongs to a low frequency signal, the second electromagnetic wave signal is a low frequency signal. In another embodiment, the electromagnetic wave signal in the second frequency band may be an electromagnetic wave absorption ratio (Specific Absorption Rate, SAR) detection antenna signal, and the frequency of the electromagnetic wave signal in the second frequency band is also less than 100MHz, which is a lower frequency signal. Then, for the frequency range of the first electromagnetic wave signal and the frequency range of the second electromagnetic wave signal, in this embodiment, the capacitance value of the capacitor 12 may be 100pf, so that the electromagnetic wave signal of the first frequency band may pass, and the electromagnetic wave signal of the second frequency band may be blocked; and the inductance of the inductor 14 is 33nH, so that the electromagnetic wave signal of the second frequency band can pass through, and the electromagnetic wave signal of the first frequency band is blocked.
It will be appreciated that in other possible embodiments, the capacitance of the capacitor 12 and the inductance of the inductor 14 may be changed according to the frequencies of the electromagnetic wave signals in the first frequency band and the electromagnetic wave signals in the second frequency band, so as to correspond to the frequencies of the electromagnetic wave signals in the first frequency band and the electromagnetic wave signals in the second frequency band, which is not limited by the present application.
