Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
For the sake of understanding, some terms and application scenarios related to the embodiments of the present application will be briefly described below.
MIMO technology: that is, a Multiple-Input Multiple-Output (MIMO) technology refers to a technology in which a transmitting end and a receiving end that perform communication use a plurality of transmitting antennas and a plurality of receiving antennas, respectively, to perform communication during communication.
In the Fifth Generation mobile communication System (5G), two millimeter wave bands of main bands are used, including: below 6GHz and above 6 GHz. Because the millimeter wave frequency band below 6GHz has the advantages of strong controllability and mature technology, the millimeter wave frequency band below 6GHz is taken as the working frequency band of the terminal at the present stage.
In a fourth Generation mobile communication System (4G) prior to the 5G communication System, a 2 × 2 MIMO antenna System is used to enable terminals to communicate in a designated operating frequency band. In the 5G communication system, since the peak rate of the 5G communication system increases by nearly ten times compared with the peak rate of the 4G communication system, the throughput is greatly improved, and in order to enable the antenna assembly to satisfy 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 satisfy the throughput of the 5G communication system for data and improve the frequency coverage of the antenna system, a scenario in which a plurality of antenna assemblies operate simultaneously is generally adopted, for example, a 4 antenna system or more antenna systems are used.
However, the number and size of the antenna assemblies are limited due to the small size of the handheld terminals such as mobile phones. In the related art, the area occupied by the antenna module is reduced by folding the antenna radiating bodies, and resonance is generated by coupling different antenna radiating bodies, so that different antenna radiating bodies can radiate signals of different frequency bands.
In the above related art, since different antenna radiators need to be coupled, the different antenna radiators are mutually coordinated and interfere with each other to cause mutual resonance, and in the process of debugging the antenna, adjusting the working frequency band corresponding to one antenna radiator may affect the working frequency bands of other antenna radiators, which results in a large difficulty in adjusting the antenna assembly.
In this application embodiment, first antenna radiator is connected with signal transmission assembly through frequency band selector for this frequency band selector can filter the signal frequency that this first antenna radiator radiated, thereby this first antenna radiator need not to carry out the coupling with other antenna radiators, and then with other antenna radiators and this first antenna radiator separation, thereby realize coordinating alone, mutual resonant mode of mutual noninterference, and then can carry out independent regulation to the antenna radiator of first antenna radiator and the signal of radiating other frequency channels, thereby antenna debugging in-process has been reduced, the adjustment degree of difficulty to the antenna module.
