Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
References herein to "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
For easy understanding, some terms and application scenarios related to the embodiments of the present application are first described below.
MIMO technology: that is, multiple-Input Multiple-Output (MIMO) technology refers to a technology in which a transmitting end and a receiving end, which perform communication during communication, perform communication using a plurality of transmitting antennas and a plurality of receiving antennas, respectively.
In the fifth generation mobile communication system (the Fifth Generation Communications System, 5G), the millimeter wave band of two main bands will be used, including: millimeter wave bands below 6GHz and above 6 GHz. The millimeter wave frequency band below 6GHz is used as the working frequency band of the terminal at present because the millimeter wave frequency band below 6GHz has the advantages of strong operability and mature technology.
In a fourth generation mobile communication system (the Forth Generation Communications System, 4G) preceding the 5G communication system, a 2 x 2 MIMO antenna system is used to enable the terminal to communicate in a specified operating frequency band. In a 5G communication system, since the peak rate of the 5G communication system increases by approximately ten times as much as that of the 4G communication system, the throughput is greatly improved, and in order to enable the antenna assemblies to meet the operating frequency band of the 5G communication system and cover a wider frequency range, a plurality of antenna radiators operating in different frequency bands are generally provided for each antenna assembly, so that in order to meet the throughput of the 5G communication system on data and improve the frequency coverage of the antenna system, a scenario in which a plurality of antenna assemblies operate simultaneously, for example, a 4 antenna system or more antenna systems are generally adopted.
However, since the volume of a handheld terminal such as a mobile phone is small, the number and volume of antenna assemblies are limited. In the related art, the area occupied by the antenna module is reduced by folding the antenna radiator, and resonance is generated by coupling between different antenna radiators, so that different antenna radiators can radiate signals in different frequency bands.
In the above related art, because different antenna radiators are required to be coupled, the different antenna radiators are mutually coordinated and mutually interfered and resonated, so that in the process of debugging an antenna, the working frequency band corresponding to one antenna radiator is adjusted to affect the working frequency bands of other antenna radiators, and the adjustment difficulty of an antenna assembly is high.
In this embodiment of the application, be connected first antenna radiator and signal transmission subassembly through the frequency channel selector for this frequency channel selector can filter the signal frequency of this first antenna radiator radiation, thereby this first antenna radiator need not to couple with other antenna radiators, and then separate other antenna radiators and this first antenna radiator, thereby realize alone the coordination, mutual noninterference mutual resonant mode, and then can carry out independent regulation to the antenna radiator of first antenna radiator and the signal of other frequency channels of radiation, thereby reduced the antenna debugging in-process, the adjustment degree of difficulty to antenna assembly.

Accordingly, the slit 41 is disposed on the metal frame, or the slit 41 is disposed on the metal rear case, and in the embodiment of the present application, the disposition position of the slit 41 is specifically defined.
In one possible implementation manner, the metal part 4 includes a first housing and a second housing, where the first housing and the second housing are both the metal part 4, the first housing is a middle frame of the terminal, and is used for fixing each component in the terminal, and the second housing is a frame of the terminal. Optionally, the first housing and the second housing are integrally formed, and at least one gap 41 is left between the first housing and the second housing.

The position and the size of the at least one opening 42 are set as required, and in the embodiment of the present application, the position and the size of the at least one opening 42 are not specifically limited.
In this implementation manner, by providing at least one opening 42 on the frame corresponding to the position of the slit 41 on the metal part 4, the radiation intensity of the signal is increased, so that the length of the slit 41 is reduced, and the quality of the metal part 4 is ensured.
Wherein the second antenna component 3 comprises a slot 41 arranged on the metal part 4 and coupled with one end of the second antenna component 3 for resonance. Optionally, a second spring plate is mounted at one end of the second antenna assembly 3, and divides the metal portion 4 corresponding to the slot 41 into a second antenna radiator and a third antenna radiator. The position of the second elastic piece and the length of the gap 41 are set according to the frequency band of the signal to be radiated. Because the second antenna radiator and the third antenna radiator are two antenna radiators formed by the same slot 41, two loop antennas are required to be mutually coupled to generate resonance in the working process, so that signals in different frequency bands are radiated. The size and the material of the second elastic sheet are set according to needs, and in the embodiment of the application, the size and the material of the second elastic sheet are not particularly limited.
