Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
With the rapid application of 5G communication, consumers have developed new demands for communication technology, such as higher communication rate, to support the application of ultra high definition video; the lower network delay meets the control speed requirement of automatic driving remote medical treatment; and the connection capacity and the traffic density are larger, so that the requirements of the ubiquitous Internet of things and the coverage of the hot spot area are met.
Among them, New Radio Sub 6G (NR Sub 6G) antennas with a frequency band below 6GHz are required to support different frequency band combinations by increasing the number of antennas due to a wide frequency band range. Thus, in the increasingly limited layout space of the mobile phone, the design of the antenna and the interference between the antennas are difficult and troublesome. At present, a mobile phone is usually provided with 8-12 antennas, and due to the fact that the number of the antennas is large, isolation between the antennas becomes small, and interference can occur between the antennas. In order to reduce interference between antennas to achieve greater bandwidth, antenna tuning schemes need to be employed for tuning.
In the related art, the tuning of the antenna is realized by adjusting the electrical length of the antenna by setting the tuner switch chip to mount different matches through a switch. However, this approach has the following drawbacks: firstly, the tuner switch chip itself increases the insertion loss of the radio frequency path, thereby limiting the further improvement of the antenna radiation efficiency; secondly, the application of the tuner switch chip has higher requirements on the over-current and voltage-withstanding capability of the tuner switch chip, and when the over-current or voltage-withstanding capability of the tuner switch chip is insufficient, the tuner switch chip can work in a nonlinear state, and the radiation stray problem can be caused; third, the use of the tuner switch chip also increases the cost of the antenna.
The antenna assembly that this application embodiment provided adopts the mode of mechanical contact to replace the electronic switch's among the correlation technique mode, adjusts the electric length of antenna, can avoid the non-linear problem that electronic switch brought to improve antenna efficiency.
It should be noted that the antenna assembly provided in the embodiments of the present application can be applied to various types of antennas, and is not particularly limited to the above-mentioned 5G antenna or NR Sub 6G antenna.

The target length is the length of the antenna assembly when operating in the target frequency band. Under the condition that the resonant frequency of the antenna assembly is consistent with the target frequency band, the antenna assembly has larger radiation power in the target frequency band, and the working efficiency of the antenna assembly is higher. Based on this, whether the length of the conductive member is adjusted to the target length can be determined according to the working efficiency of the antenna assembly.

Step 6100, obtaining the current working efficiency of the antenna assembly in the process of controlling the driving mechanism to drive the conductive member to move.
And 6200, determining that the length of the conductive piece is adjusted to the target length under the condition that the current working efficiency is greater than a preset first threshold value, and controlling the driving mechanism to stop driving the conductive piece to move.
The first threshold may be used to gauge whether the operating efficiency of the antenna assembly meets a requirement. The first threshold may be 50%, for example. The first threshold may be set by a person skilled in the art according to actual experience or simulation test results, and the embodiment of the present application is not particularly limited thereto.

Specifically, the motor drives the rotating shaft to rotate along the first direction, so that the length of the conductive piece is lengthened, in the process of controlling the length of the conductive piece to be lengthened, the working efficiency of the antenna assembly is obtained, if the working efficiency of the antenna assembly is gradually increased, the motor drives the rotating shaft to rotate along the first direction continuously, then the current working efficiency of the antenna assembly is obtained, and under the condition that the current working efficiency is larger than a preset first threshold value, the length of the conductive piece is determined to be adjusted to the target length, and the driving mechanism is controlled to stop driving the conductive piece to move. If the working efficiency of the antenna assembly is gradually reduced, the length of the conductive piece needs to be shortened, at the moment, the rotating direction of the rotating shaft is changed, the rotating shaft is driven by the motor to rotate along the second direction, so that the length of the conductive piece is shortened, in the process of controlling the length of the conductive piece to be shortened, the current working efficiency of the antenna assembly is obtained, under the condition that the current working efficiency is greater than a preset first threshold value, the length of the conductive piece is determined to be adjusted to the target length, and the driving mechanism is controlled to stop driving the conductive piece to move. Based on this, the length of the conducting piece is adjusted through the driving mechanism, so that the tuning of the antenna is realized.
In the embodiment of the application, the electrical length of the conductive member can be adjusted through the driving mechanism, so that the antenna assembly has larger radiation power, and the performance of the antenna assembly is improved. In addition, the electric length of the conductive piece can be adjusted by the working frequency band of the electronic equipment, and wider frequency coverage can be realized. And the problem of radiation stray caused by the fact that the switch chip works in a non-linear state due to overcurrent or insufficient withstand voltage in the process of tuning the antenna through the tuner switch chip can be avoided by utilizing a mechanical mode.
