Description
Technical Field
The invention relates to the technical field of communication equipment, in particular to a mobile terminal.
Background
The fifth generation mobile communication technology (5G) can provide higher communication speed, lower latency, and a larger number of simultaneous connections than the previous generation technologies. Among them, the millimeter wave communication technology with a frequency band above 20GHz is one of the key technologies in the 5G technology because of having a very wide communication bandwidth. Since the millimeter wave band is divided into 5G bands in many countries and regions in the world, various electronic products, particularly mobile communication terminals such as mobile phones, equipped with millimeter wave antenna modules will be increasing in the future.
Due to the large propagation loss and reflection loss of millimeter waves in space, the millimeter wave communication technology standard in the 5G technology stipulates that a millimeter wave antenna should have a gain above a certain degree to compensate for various losses in a spatial link. This requires the millimeter wave antenna to be in the form of an antenna array, and to realize phased array beam forming by controlling the phase difference between the sub-antennas in the array, so that the synthesized beam has higher gain.
In the prior art, due to the limitation of the internal space of mobile terminals such as mobile phones, the positions for arranging the millimeter wave antennas are very limited, so that the antenna gain is low.
Disclosure of Invention
The embodiment of the invention provides a mobile terminal, which aims to solve the problem that the gain of an antenna is lower due to the space limitation of the mobile terminal.
An embodiment of the present invention provides a mobile terminal, including:
the screen comprises a shell, a first cover plate and a second cover plate, wherein the shell is provided with a screen cover plate;
the telescopic assembly is movably connected with the shell and can move between a first position and a second position;
the yagi antenna comprises an active oscillator and a director, the active oscillator is arranged below the screen cover plate, and the director is arranged on one side of the telescopic component;
when the telescopic assembly is located at the second position, the director is located outside the shell, and the active oscillator and the director are arranged in parallel.
In the embodiment of the invention, the active oscillator is arranged below the screen cover plate, and the director is arranged on the telescopic component, so that the application of the yagi antenna on the mobile terminal is realized. Therefore, the gain of the antenna can be improved in a smaller installation space.

Referring to fig. 1, an embodiment of the present invention provides a mobile terminal, where the mobile terminal includes:
the display screen comprises a shell 11, wherein the shell 11 is provided with a screen cover plate 111;
a telescopic assembly 12, wherein the telescopic assembly 12 is movably connected with the shell 11 and can move between a first position and a second position;
the yagi antenna 13, the yagi antenna 13 includes an active oscillator 131 and a director 132, the active oscillator 131 is disposed below the screen cover 111, and the director 132 is disposed on one side of the telescopic assembly 12;
when the telescopic assembly 12 is located at the second position, the director 132 is located outside the housing 11, and the active vibrator 131 and the director 132 are arranged in parallel.
To better illustrate the specific implementation manner of the embodiment of the present invention, a three-axis coordinate system as shown in fig. 1 is established, in the Y-axis direction, the upper end is the top end of the housing 11, and the lower end is the bottom end of the housing 11; the Z-axis is the thickness direction of the housing.
The housing 11 may be provided with an opening adapted to the telescopic assembly 12, and when the telescopic assembly 12 is located at the first position, the top surface of the telescopic assembly 12 may cover the opening. In an alternative embodiment, the retraction assembly 12 is manually movable between a first position and a second position; in an alternative embodiment, a drive member may be provided within housing 11, whereby retraction assembly 12 is driven from the first position to the second position, and whereby retraction assembly 12 is controlled manually or by the drive member to return from the second position to the first position. The driving component may be a motor, an electromagnet, or an elastic component, and the specific structure may refer to the related art, which is not further limited herein.
Specifically, the housing 11 is further provided with a display module, and the display module is disposed below the screen glass 111. The active vibrator 131 may be located at one side of the display module.
In an alternative embodiment, the yagi antenna may be a millimeter wave antenna. Of course, in other embodiments, the yagi antenna may also be used as an antenna in other forms, such as a microwave antenna.
It will be appreciated that since the directors 132 are provided on the telescoping assembly 12, they do not interfere with and are not easily affected by the side and bottom ITO traces. In addition, when director 132 was out of work, can control flexible subassembly 12 and contract in casing 11 to can not occupy the peripheral extra space of screen, be favorable to satisfying comprehensive screen narrow frame design demand.
In the embodiment of the invention, the active oscillator is arranged below the screen cover plate 111, and the director is arranged on the telescopic component 12, so that the application of the yagi antenna on the mobile terminal is realized. Therefore, the gain of the antenna can be improved in a smaller installation space.
Optionally, in an optional embodiment, the guiding device 132 is disposed on a side of the telescopic assembly 12 facing the screen cover 111 (a side facing the screen cover 111 when the telescopic assembly 12 is located at the first position). Of course, in other embodiments, the guide 132 may be disposed on either side of the telescoping assembly 12 adjacent the top surface if the telescoping assembly 12 is rotatable in the XY plane when the telescoping assembly 12 is in the second position. Since the guiding device 132 is disposed on the side of the retractable assembly 12 facing the screen cover 111, the rotation control of the retractable assembly 12 is not required, and the guiding device can be applied to a mobile terminal in which the retractable assembly 12 cannot rotate, thereby improving the application range. In addition, when the retractable assembly 12 is applied to a mobile terminal with a rotatable retractable assembly 12, the retractable assembly 12 does not need to be controlled to rotate, so that the consumption of electric energy can be reduced.
Optionally, the active vibrator 131 is disposed in parallel with the director 132. For example, in the present embodiment, the active vibrator 131 and the director 132 are both parallel to the edge of the top of the housing 11.

Of course, in other embodiments, if the director 132 is configured as a movable structure, the active element 131 and the director 132 may not be arranged in parallel, as long as the active element 131 and the director 132 may keep relatively parallel arrangement when the yagi antenna 13 is in operation, and at the same time, the distance between any two adjacent directors 132 for operation is equal.
It should be understood that, in the embodiment of the present invention, when the plurality of directors 132 are provided, if the communication environment is good and the requirement on the antenna gain is not high, the telescopic assembly 12 may be controlled to be located between the first position and the second position, so that part of the directors 132 are exposed out of the housing.

When the yagi antenna 13 is provided as one, its maximum radiation direction is as indicated by the arrow in fig. 1; when the yagi antenna 13 is provided in plural, its maximum radiation direction is as indicated by an arrow in fig. 2. In this embodiment, since the plurality of yagi antennas 13 are provided, beam scanning can be performed after the array is formed, so as to obtain a larger spatial coverage.
