As shown in fig. 2a and 3a, the present application provides an electronic device. In one embodiment, the electronic device includes a housing assembly 20, wherein a receiving cavity is disposed in the housing assembly 20; an ejection mechanism 110 including a radiation unit 111 for supporting millimeter wave communication; a conductive mechanism 120 fixed in the housing assembly 20 and spaced apart from the radiation unit 111; a driving mechanism 130 connected to the ejection mechanism 110, for driving the ejection mechanism 110 to extend out of the accommodating cavity or retract back into the accommodating cavity, so as to move the radiation unit 111 relative to the conductive mechanism 120; when the radiation unit 111 moves relative to the conductive mechanism 120, the radiation direction and/or radiation power of the millimeter wave signal radiated by the radiation unit 111 changes.

Millimeter waves refer to electromagnetic waves having a wavelength on the order of millimeters, and having a frequency of about 30GHz to 300 GHz. The electromagnetic wave is an oscillating particle wave which is derived and emitted in space by an electric field and a magnetic field which are in the same phase and are perpendicular to each other, is an electromagnetic field which propagates in a wave form and has the particle duality. The electric field and the magnetic field which oscillate in phase and are perpendicular to each other move in space in the form of waves, and the propagation direction of the waves is perpendicular to the plane formed by the electric field and the magnetic field.

The 3GPP has specified a list of frequency bands supported by 5G NR, the 5G NR spectrum range can reach 100GHz, and two frequency ranges are specified: frequency range 1(FR1), i.e. the sub-6 GHz band, and Frequency range 2(FR2), i.e. the millimeter wave band. Frequency range of FR 1: 450MHz to 6.0GHz and maximum channel bandwidth of 100 MHz. The frequency range of FR2 is 24.25GHz-52.6GHz, and the maximum channel bandwidth is 400 MHz. The near 11GHz spectrum for 5G mobile broadband comprises: 3.85GHz licensed spectrum, for example: 28GHz (24.25-29.5GHz), 37GHz (37.0-38.6GHz), 39GHz (38.6-40GHz) and 14GHz unlicensed spectrum (57-71 GHz). The working frequency bands of the 5G communication system comprise three frequency bands of 28GHz, 39GHz and 60 GHz.

In one embodiment, the radiation unit 111 may be fixed to the ejection mechanism 110. Radiating element 111, for example, radiating element 111 for supporting millimeter wave communications may be implemented as a phased antenna array, which may be an antenna array of patch antennas, dipole antennas, yagi antennas, beam antennas, or other suitable antenna elements.

In one embodiment, the ejection mechanism 110 may include a slide rail disposed within the housing assembly 20 within the electronic device on which the radiating element 111 may be disposed and a locking mechanism (not shown) that may be used to lock or unlock the radiating element 111. When the locking mechanism releases the radiation unit 111, the driving mechanism 130 can drive the radiation unit 111 to move, and when the radiation unit 111 moves into the housing assembly 20 of the electronic device, the locking mechanism locks the radiation unit 111.

It should be noted that the structure of the ejection mechanism 110 is not limited in the present application, so as to implement the ejection function.

In one embodiment, the conductive element 120 is fixed and the conductive element 120 is spaced apart from the ejection element 110, i.e. the conductive element 120 is spaced apart from the radiation unit 111 of the ejection element 110. For example, the conductive mechanism 120 may be secured within the housing assembly 20 of the electronic device.

In one embodiment, the conductive mechanism 120 is made of a magnetic conductive material or an electrically conductive material. For example, the conductive member 120 can be made of a metal conductive material, a copper material, a ferrite material, or the like. In the present application, the material of the conductive mechanism 120 is not limited further, and may be a material having a high magnetic permeability, a material having a high dielectric constant, or the like. When the radiation element 111 moves relative to the conductive mechanism 120, the electromagnetic field distribution around the radiation element 111, the resonant frequency of the antenna, the gain, etc. are affected.

In one embodiment, the drive mechanism 130 may include a power motor and transmission unit (not shown). The transmission unit may be a pushing member directly abutting against the ejection mechanism 110, so as to simply and directly convert the power of the power motor into a pushing force for the ejection mechanism 110. In addition, the power motor may also be directly associated with an electronic device through which intelligent control of the ejection mechanism 110 is achieved.

In an embodiment, the driving mechanism 130 may further include a spring assembly (not shown) having a snap-fit function, and the spring assembly cooperates with the ejection mechanism 110 to control the position of the conductive mechanism 210 relative to the radiation unit 111. For example, the relative displacement of the ejection mechanism 110 and the conductive mechanism 120 is minimal (original state) when the springs in the spring assembly are in a compressed state, i.e., the conductive mechanism 120 is not moving relative to the radiating element 111 of the ejection mechanism 110. The spring returns to the original shape, i.e. pushes the ejection mechanism 110 to move, so that the radiation unit 111 of the ejection mechanism 110 moves relative to the conductive mechanism 120; alternatively, when the spring in the spring assembly is in a stretched state, the relative displacement between the pop-up mechanism 110 and the conductive mechanism 120 is the largest, and the spring returns to its original state by pulling the pop-up mechanism 110.

It should be noted that the structure of the driving mechanism 130 is not limited in the present application, so as to implement the driving function of the ejection mechanism 110.

The radiation of the millimeter wave has directivity. For a dipole array antenna, the conductive structure 120 corresponds to a planar radiator. As long as the radiation unit 111 is not completely attached to the conductive member 120, the directivity or gain of the millimeter wave radiated by the radiation unit 111 is higher than that of the free space. From the perspective of the radiation pattern in which the radiation unit 111 radiates the millimeter wave, the radiation performance variation of the radiation unit 111 under the influence of the conductive mechanism 120 can also be reflected on the radiation pattern. The radiation pattern is a graph describing the dependence relationship between the intensity and the direction (angle) of radio waves emitted by an antenna or other signal sources, and the radiation pattern is a relationship curve in the same direction of the ratio of the field intensity of a certain point in any direction of a far zone to the maximum field intensity of the same distance. The radiation pattern is a mathematical function or a graphically represented spatial coordinate function representing the radiation characteristics of the antenna.

When the radiation unit 111 moves relative to the conductive mechanism 120, the waveform (electromagnetic wave) of the millimeter wave signal radiated by the radiation unit 111 is disturbed, the radiation pattern of the millimeter wave radiated by the radiation unit 111 is different, and the number of lobes and the gain of the beam formed by the radiation unit 111 are also changed, so as to adjust the radiation direction and the radiation power of the millimeter wave signal radiated by the radiation unit 111.

In the embodiment of the present application, the electronic device includes a housing assembly 20, an ejection mechanism 110, a driving mechanism 130, and a conductive mechanism 120, wherein: a radiation unit 111 for supporting millimeter wave communication is arranged on the ejection mechanism 110; the conductive mechanism 120 is spaced apart from the radiation unit 111; the driving mechanism 130 is connected to the ejection mechanism 110, and is configured to drive the ejection mechanism 110 to extend out of the accommodating cavity or retract back into the accommodating cavity, so as to move the radiation unit 111 relative to the conductive mechanism 120; when the radiation unit 111 moves relative to the conductive mechanism 120, the radiation direction and/or the radiation power of the millimeter wave signal radiated by the radiation unit 111 changes, so that higher gain and impedance period change can be realized, and further, high gain, beam forming and beam scanning functions required by millimeter wave 5G communication are realized, so as to improve the communication quality. The design structure occupies small space and volume, is easy to debug and has high stability.

It should be noted that, in the embodiment of the present application, the radiation Power may be understood as an Effective Isotropic Radiated Power (EIRP).

It should be noted that the ejection mechanism 110 may be ejected along any border of the middle frame of the periphery of the housing assembly 20 under the driving of the driving mechanism 130, or may be ejected from the rear cover of the housing assembly 20. For example, the eject mechanism 110 may eject toward the top edge of the center frame, the eject mechanism 110 may eject toward the side edge of the center frame, and the eject mechanism 110 may eject toward the rear cover. The ejection direction of the ejection mechanism 110 is not particularly limited in this embodiment, and in this embodiment, the ejection mechanism 110 ejects toward the top edge of the middle frame or ejects toward the rear cover without making a special statement.

In one embodiment, the conductive mechanism 120 is fixed in the receiving cavity of the housing assembly 20. Specifically, the conductive mechanism 120 may be disposed parallel to the rear cover, or may be disposed perpendicular to the rear cover. In this embodiment, the arrangement direction of the conductive mechanism 120 is not specifically limited, and in this embodiment, the conductive mechanism 120 is arranged parallel to the rear cover without special statement.

In one embodiment, the conductive structure 120 may be a planar structure, such as a rectangle, a triangle, a circle, a polygon, an irregular pattern, and the like.

Optionally, the conductive mechanism 120 may also be a curved structure.

In one embodiment, the conductive mechanism 120 is adjustable in size. For example, the shape, size, etc. of the conductive mechanism 120 may be set according to the radiation requirement of the millimeter wave signal.

As shown in fig. 2a, when the eject mechanism 110 is maintained at the first position, the radiation unit 111 is disposed parallel to the conductive mechanism 120, and the distance between the radiation unit 111 and the conductive mechanism 120 is a first distance L1. For example, the conductive mechanism 120 may be located on the same plane as the radiation unit 111, or may be located on a different plane from the radiation unit 111. It should be noted that, when the conductive mechanism 120 and the radiation unit 111 are located on the same plane, the conductive mechanism 120 and the radiation unit 111 are disposed at a distance, and the first distance L1 is maintained.

The first position may be understood as a position where the ejection mechanism 110 is closest to the conductive mechanism 120, i.e., the ejection mechanism 110 is located at an original position within the housing assembly 20 of the electronic device where no movement occurs.

It should be noted that the information such as the shape, the size, the first distance L1 from the radiation unit 111, and the like of the conductive mechanism 120 can be set according to actual requirements, and is not further limited herein. The first distance L1 should satisfy the minimum requirement of millimeter wave radiation, and under the condition of the first distance L1, the radiating unit 111 can radiate a millimeter wave signal with good directivity or high gain, and the millimeter wave signal can satisfy the basic requirement of communication.

In one embodiment, the drive mechanism 130 is capable of driving the eject mechanism 110 to move from the first position to the second position in the first direction. Specifically, when the ejection mechanism 110 is held at the first position, the driving mechanism 130 is disposed in parallel with the conductive mechanism 120 at a distance from the conductive mechanism 120, and the ejection mechanism 110 is disposed close to the rear cover. The ejection mechanism 110 is provided with a radiation unit 111 for radiating a millimeter wave signal, and the radiation unit 111 includes a radiation layer and a ground dielectric layer, where the radiation layer and the ground dielectric layer are disposed opposite to each other. The wave beam direction of the millimeter wave signal is radiated towards the direction of the rear cover by taking the radiation layer as a reference surface, namely, the direction from the grounding medium layer to the radiation layer is the positive direction of the wave beam direction. The conductive means 120 is arranged adjacent to the display screen of the electronic device, i.e. adjacent to the ground dielectric layer of the radiating element 111.

The first direction may be a direction in which the electronic device is directed from the screen to the rear cover, that is, a beam direction of the millimeter wave signal, and may also be a direction perpendicular to a plane in which the conductive mechanism 120 is located.

As shown in fig. 2b, when the ejection mechanism 110 moves from the first position to the second position along the first direction, the radiation unit 111 is disposed parallel to the conductive mechanism 120, and the distance between the radiation unit 111 and the conductive mechanism 120 is a second distance, wherein the second distance is greater than the first distance L1. Of course, the ejection mechanism 110 may drive the radiation unit 111 to move back and forth in a first direction (refer to the solid arrow direction in fig. 2) relative to the conductive mechanism 120 under the driving of the driving mechanism 130.

In an embodiment, the driving mechanism 130 may drive the ejection mechanism 110 to move to the second position along the first direction, that is, may drive the radiation unit 111 to move to the second position along the first direction relative to the conductive mechanism 120. When the radiation unit 111 moves to the second position, that is, the eject mechanism 110 ejects toward the back cover.

As shown in fig. 3a, in one embodiment, when the ejection mechanism 110 is maintained at the first position, the radiation unit 111 is disposed parallel to the conductive mechanism 120, and the radiation unit 111 is spaced apart from the conductive mechanism 120 by a first distance L1.

As shown in fig. 3b, the driving mechanism 130 is capable of driving the eject mechanism 110 to move from the first position to the third position in the second direction. The second direction is a direction parallel to the plane of the conductive mechanism 120. The second direction may also be understood as a direction from the center point of the middle frame to the peripheral edge of the middle frame. When the middle frame comprises an upper frame, a lower frame, a left frame and a right frame, wherein the upper frame can be understood as being close to the frame for arranging the receiver, and the lower frame can be understood as being close to the frame for arranging the receiver. As shown in fig. 3, the second direction may include any scattering direction pointing from the center point of the middle frame to the peripheral edges (upper frame, lower frame, left frame, and right frame), for example, may be pointing from the center point of the middle frame to the upper frame (refer to the direction of the solid arrow in fig. 3). That is, when the eject mechanism 110 is capable of moving from the first position to the third position along the second direction, the eject mechanism 110 thereof can also eject toward any peripheral edge of the middle frame.

When the ejection mechanism 110 moves from the first position to the third position along the second direction, the radiation unit 111 is disposed parallel to the conductive mechanism 120, and a distance between a plane of the radiation unit 111 and a plane of the conductive mechanism 120 is the first distance L1. That is, when the ejection mechanism 110 moves, the vertical distance between the radiation unit 111 and the conductive mechanism 120 does not change, and the linear distance changes. Here, the vertical distance may be understood as a distance between a first plane in which the radiation unit 111 is located and a second plane in which the conductive mechanism 120 is located. The straight distance may be understood as the distance between the center point of the radiation unit 111 and the center point of the conductive means 120.

In an embodiment, the number of the conductive mechanisms 120 may be multiple, and the multiple conductive mechanisms 120 are arranged in an array. For example, the number of the conductive mechanisms 120 may be two, three, four or more, and the plurality of conductive mechanisms 120 are all located in the same plane and are arranged in parallel with the radiation unit 111.

In an embodiment, the radiation unit 111 comprises at least a dipole antenna array, and the conductive mechanism 120 moves relative to the dipole antenna array. When the dipole antenna array is not moved, part or all of the dipole antenna array is orthographically projected on the conductive structure 120.

In one embodiment, the dipole antenna array includes a plurality of dipole antennas arranged in an array. The dipole antenna array can be a linear array, a two-dimensional rectangular array, or the like. As shown in fig. 4, dipole antenna 40 may include a first arm 410 and a second arm 420, and is fed at an antenna feed. Wherein the feeding portion includes a first feeding point 410a disposed on the first arm 410 and a second feeding point 410b disposed on the second arm 420. The current signal is fed through the first feeding point 410a and the second feeding point 410b, and the directivity of the dipole antenna can be controlled by adjusting the magnitude and phase of the current signal.

In an embodiment, as shown in fig. 5a and 5b, the radiating element 111 comprises a dipole antenna array 510 and a patch antenna array 520. The dipole antenna array 510 shown in fig. 5a has a phase-scan function, and the dipole antenna array 510 shown in fig. 5b does not have a phase-scan function. The dipole antenna array 510 is disposed around the patch antenna array 520, that is, the dipole antenna array 510 is disposed at the periphery of the patch antenna array 520, and the patch antenna array 520 is entirely orthographically projected on the conductive mechanism 120, so that the radiation coverage of the antenna module 10 can be improved, and the radiation intensity of an antenna system in the electronic device can be improved.

Optionally, the radiating element 111 may also include a yagi antenna into which a dipole antenna may be incorporated (e.g., by incorporating a reflector and director into the dipole antenna).

As shown in fig. 6, in an embodiment, the electronic device further includes a detection module 140 and a control module 150. The detection module 140 is configured to detect gain information of a main lobe of the radiation unit 111 towards a base station; and the control module 150 is respectively connected to the detection module 140 and the driving mechanism 130, and configured to send a driving signal according to the gain information, so that the driving mechanism 130 drives the ejection mechanism 110 to move, where the driving signal at least includes movement vector information for driving the ejection mechanism 110 to move.

In this embodiment, the base station and the electronic device implement communication connection by using a beamforming technology. Based on beam management, it can be seen that the beams of the base station and the beams of the electronic device are aligned with each other to achieve maximization of the receive gain and the transmit gain in the link. Beam management principle: the base station transmits wireless signals (beam scanning) by using different beams (t 1-t 8) in sequence, the electronic equipment switches the beams (r 1-r 4) to receive the wireless signals and reports related information (beam report) to the base station, and the electronic equipment determines a preferred beam (beam measurement) for receiving the wireless signals according to the wireless signals with the maximum receiving value.

In this embodiment, the following beam management method may be adopted: the base station transmits a radio signal using different beams in turn, the electronic device switches the beams to receive the radio signal, and determines the gain of the main lobe of the radiating element 111 towards the base station.

The control module 150 may send a driving signal according to the magnitude of the gain, so that the driving mechanism 130 drives the ejection mechanism 110 to move, where the driving signal at least includes information of a movement vector for driving the ejection mechanism 110 to move. The motion vector information may include information such as a direction of movement, a size of a movement distance, and the like.

In this embodiment, the electronic device may obtain gain information of the main lobe of the radiation unit 111 facing the base station, and drive the radiation unit 111 to move relative to the conductive mechanism 120 according to the gain information, that is, may dynamically adjust the radiation direction and/or radiation power of the radiation unit 111 for radiating the millimeter waves according to the environmental change of the radiation unit 111, thereby implementing high gain, beam forming, and beam scanning functions required by millimeter wave 5G communication to improve communication quality.

In an embodiment, the control module 150 stores a corresponding relationship table of motion vector information and gain magnitude in advance. That is, the correspondence table between the motion vector information and the gain size may be preset and obtained in different scenes, and the obtained correspondence table may be stored.

It should be noted that, in other embodiments, other beam management methods may also be used, which is only an example, and the layout of the antenna system in this embodiment is not affected by any beam management method.

In an embodiment, the electronic device further comprises: and the trigger key (not shown) is connected with the driving mechanism and is used for triggering the driving mechanism so as to drive the ejection mechanism to extend out of the accommodating cavity or retract back into the accommodating cavity. Specifically, the trigger button is connected with the driving mechanism and movably arranged on the outer periphery of the shell assembly, and the ejecting direction of the ejecting mechanism and the trigger button are positioned on the same side. The structure realizes the movement of the radiation unit through the mechanical mechanism, does not need complex circuit control, and can realize the movement of the radiation unit in the accommodating cavity, and meanwhile, because the pop-up direction of the pop-up mechanism and the trigger key are positioned on the same side, the installation and the layout of other components in the shell can be convenient.

In one embodiment, the ejection mechanism may be a camera module. For example, the pop-up mechanism may be integrated with a flash, an earpiece, an ambient light sensor, a battery, a microprocessor, a camera, etc. It should be noted that the number of the cameras may be one, two, three, four, or more to form multi-camera shooting, and in this embodiment, the number and the position of the specific integration of the cameras are not specifically limited. The ejecting mechanism can move to the outside of the shell assembly by means of power provided by the driving mechanism in a working state, and can also be hidden in the accommodating cavity in a non-working state.

In one embodiment, the circuit board may be a motherboard of the electronic device. Wherein the processor of the electronic device may be disposed on the circuit board. One, two or more of functional components such as a motor, a microphone, a loudspeaker, a receiver, an earphone interface, a universal serial bus interface (USB interface), a camera, a distance sensor, an ambient light sensor, a gyroscope and the like can be integrated on the circuit board.

The electronic Device may be a communication module including a Mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable Device (e.g., a smart watch, a smart bracelet, a pedometer, etc.), or other settable antenna.

As shown in fig. 7, an embodiment of the present application further provides an antenna performance adjusting method, which is applied to the electronic device in any of the embodiments. The antenna performance adjustment method includes steps 702-704. Wherein:

step 702, detecting gain information of a main lobe of a radiation unit towards a base station.

In this embodiment, the base station and the electronic device including the electronic device implement communication connection by using a beamforming technology. Based on beam management, it can be seen that the beams of the base station and the beams of the electronic device are aligned with each other to achieve maximization of the receive gain and the transmit gain in the link.

Specifically, the base station sequentially uses different beams (t 1-t 8) to transmit wireless signals (beam scanning), and the electronic equipment switches beams (r 1-r 4) to receive the wireless signals and reports beam information (beam report) to the base station; when the electronic device determines the gain of the main lobe of the radiating element towards the base station direction (beam measurement) according to the received wireless signal with the maximum value.

In an embodiment, the electronic device may store a corresponding relationship table of motion vector information and gain magnitude in advance. That is, the correspondence table between the motion vector information and the gain size may be preset and obtained in different scenes, and the obtained correspondence table may be stored.

In an embodiment, if the number of the conductive mechanisms in the electronic device is multiple, the driving signal further includes identification information of the conductive mechanisms. The identification information can be used for identifying the identity of the conductive mechanism. That is, when there are a plurality of conductive mechanisms, the electronic device may transmit a driving signal carrying identification information and motion vector information according to the magnitude of the gain. That is, the number of the driving signals may be one or more, wherein one driving signal is used for controlling one conductive mechanism to move relative to the radiation unit. The electronic device can simultaneously control the plurality of conductive mechanisms to move relative to the radiating unit according to the gain by a plurality of driving signals so as to adjust the radiation power and/or the radiation direction of the millimeter wave signals radiated by the radiating unit, realize higher gain and impedance periodic variation, and further realize high gain, beam forming and beam scanning functions required by millimeter wave 5G communication so as to improve the communication quality.
