Differently, the antenna and the mobile terminal provided by the embodiments of the present invention can adjust the effective use area of the antenna according to the strength of the wireless signal received by the antenna, and improve the performance of the antenna.

The above described objects, features and advantages of the present invention will become more apparent from the aspects of the invention.

Specific details are set forth in the following description in order to provide a thorough understanding of the invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar promotion without departing from the scope of the present invention. The invention is therefore not limited by the specific embodiments disclosed below.

As shown in FIG. 7 and FIG. 8 , an embodiment of the present invention provides an antenna, including: an antenna substrate 1 having at least one through hole 11; on an upper surface of the antenna substrate 1 and covering the a first conductive layer 2 of the via hole 11, the first conductive layer 2 having a first state in which the surface of the first conductive layer 2 is planar (as shown in FIG. 7) and a surface of the first conductive layer 2 having a convex surface The second state of 21 (shown in Figures 8 and 9); a driving device (not shown) that controls the first conductive layer 2 to switch between the first state and the second state. The antenna provided by the embodiment of the present invention can control the first conductive layer to be in different states according to the strength of the received wireless signal, because the effective use area of the antenna corresponding to the first conductive layer is different in different states. In order to adjust the effective use area of the antenna, the performance of the antenna is improved.

Specifically, in a preferred embodiment of the present invention, when the wireless signal received by the antenna is strong, that is, when the strength of the wireless signal received by the antenna is greater than or equal to the first threshold, the driving device controls the first a conductive layer is switched to the first state; in the embodiment, when the wireless signal received by the antenna is weak, that is, when the strength of the wireless signal received by the antenna is less than a second threshold, the driving device controls the first A conductive layer is switched to the second state. The first threshold and the second threshold may be preset values, and the first threshold and the second threshold may be the same or different. It should be noted that, in the embodiment of the present invention, the material of the first conductive layer 2 is a conductive material having ductility, and when the first conductive layer 2 is in the second state, the through hole 11 is The protrusions 21 are in one-to-one correspondence.

It should be noted that the wireless signal received by the antenna in the embodiments of the present invention may be a wireless signal that the antenna is receiving, or may be a wireless signal that the antenna has received, or may be a wireless antenna to be received by the antenna. signal.

In an embodiment of the present invention, as shown in FIG. 10, the driving device includes: a support member 31 located in the through hole 11 and movable in the direction of the through hole 11, and connected to the support member 31 for controlling The first driving member 32 is moved in the direction of the through hole 11 by the support member 31. The first driving member 32 controls the first conductive layer 2 by controlling the relative positions of the supporting member 31 and the through hole 11. Switching between the first state and the second state. The support member 31 has a one-to-one correspondence with the through holes 11. When there are a plurality of through holes 11, there are a plurality of support members 31. In this embodiment, since the material of the first conductive layer 2 is a conductive material having ductility, when the first driving member 32 controls the support member 31 to move upward in the direction of the through hole 11 to a certain distance. The support member 31 will give the first conductive layer 2 an upward external force. Under the external force, the position of the first conductive layer 2 to which the force is applied will bulge upward with the support member 31. So that the first conductive layer 2 assumes a second state in which the surface has the protrusions 21. When the support member 31 is gradually moved downward in the direction of the through hole 11, the force applied to the first conductive layer 2 is gradually reduced until it disappears, when the support member 31 is applied to the first When the force on the conductive layer 2 completely disappears, the surface of the first conductive layer 2 returns to a first state in which the surface is flat under the action of its own ductility.

It should be noted that, in the embodiment of the present invention, the top end of the support member 31 is preferably a hemispherical shape, so that when the support member 31 gives the first conductive layer 2 a direction along the through hole 11 When the force is the same, the pressure at the contact area between the support member 31 and the first conductive layer 2 is small under the same force, and the first conductive layer 2 is less likely to be broken.

In the antenna provided by the embodiment of the present invention, when the wireless signal received by the antenna is strong, the support member 31 can be controlled to move downward by the first driving member 32, so that the first conductive layer 2 is in the The first conductive layer surface is in a planar first state to reduce the occupied space of the antenna, and when the wireless signal strength received by the antenna is weak, the support member 31 is controlled to be upward by the first driving member 31. Moving, the first conductive layer 2 is switched to a second state in which the surface of the first conductive layer has the protrusions 21 to increase the effective use area of the antenna and improve the antenna performance of the antenna. That is, the antenna provided by the embodiment of the present invention can switch the first conductive layer 2 between the first state and the second state by moving the support member 31 up and down by the first driving member 32. It is applicable to wireless signals of different strengths, with strong adaptability and high antenna performance.

It should be noted that the second state of the first conductive layer 2 may have various conditions. By controlling the amplitude of the up and down movement of the first driving member 32, different second states can be obtained. For example, when the first driving member 32 is moved up to the maximum, the protrusion 21 is the largest protrusion, and the effective area of the antenna at this time. At the maximum, when the amplitude of the upward movement of the first driving member 32 is reduced, the size of the protrusions 21 is also reduced; by controlling the amplitude of the upward movement of the first driving member 32, different protrusion sizes can be obtained, that is, different sizes can be obtained. The effective area of the antenna. In practical applications, the wireless signal strength received by the antenna can be used to determine how large the effective area of the antenna is, and then the desired antenna effective area is obtained by controlling the amplitude of the movement of the first driving member.

In practice, a mobile communication base station antenna typically radiates a signal to the ground in the shape of a sector, which receives the signal and converts it into a form that the user can perceive. Therefore, in the connection between the antenna and the mobile communication base station, the antenna simultaneously receives signals transmitted by one or more base stations, and the signals are strong and weak, and the stronger signal direction is not necessarily perpendicular to the antenna. The plane of the substrate is located, so in an embodiment of the invention, the first driving member 32 is further used to control the support member 31. Moving in a direction at an angle a to the axial direction of the through hole 11, as shown in Fig. 11, when the first conductive layer 2 is in the second state, the protrusions 21 on the surface thereof are in different directions. Among them, the angle α can be determined by the signal direction.

Wherein, the angle α ranges from [0°, 90°], including the endpoint value. Preferably, the angle α is matched with an angle formed by a direction of a strongest signal of the wireless signal received by the antenna and an axial direction of the through hole 11 , and specifically may be: an axial direction of the support member 31 and wireless The direction of the strongest signals in the signal is the same or parallel. The angle between the axial direction of the support member 31 and the axial direction of the through hole 11 is an angle α. The strongest signal is the signal with the highest signal strength among the plurality of wireless signals.

It should be noted that, in different situations, the wireless signal strength of the wireless signals received by the antenna may be different, and the direction of the strongest signal in the wireless signal may not be a fixed direction. In the embodiment of the present invention, The first driving member 32 controls the distance of the support member 31 in the direction of the through hole 11 and the angle between the support member 31 and the through hole 11 in the axial direction to control the first conductive layer 2 to be at In the second state, the area and angle of the protrusion 21 are used to obtain an optimization of the antenna area and performance.

In this embodiment, the second driving component 5 can be used to control the antenna detecting terminal 4 to rotate around its center to detect each wireless signal received by the antenna, and detect each detected signal. The wireless signal and its corresponding direction are sent to the processor, and the processor calculates the strength of each wireless signal and its corresponding direction, and selects the strongest (ie, the strongest) wireless signal and its direction, thereby The direction of the strongest wireless signal adjusts the angle of the surface protrusion 21 of the first conductive layer 2 to receive the strongest wireless signal and improve the antenna performance of the antenna. That is, according to the direction of the strongest wireless signal acquired, the axial direction of the control support 31 is the same or parallel to the direction of the strongest wireless signal.

It should be noted that, when the first conductive layer 2 is in the second state, the first driving member 32 preferably controls the rotation of the support member 31 to the direction in which the wireless signal is strong, wherein the support When the member 31 is rotated to the direction in which the wireless signal is strongest, the axial direction of the support member 31 is the same as the direction in which the wireless signal is strongest.

In an embodiment, the first driving member 32 can also be automatically controlled to adjust the size and angle of the surface protrusions 21 of the first conductive layer 2.

The current position of the member 31, when the current position of the support member 31 matches the strongest direction of the wireless signal obtained by the processor, controlling the first driving member 32 to be inoperative; when the current position of the support member 31 is When the strongest direction of the wireless signal obtained by the processor does not match, the first driving member 32 controls the support member 31 to rotate to the direction in which the wireless signal is strongest, thereby achieving active adjustment without being affected by the position of the antenna substrate. The effect is to achieve more energy field conversion, greatly improving the signal strength and sensitivity of the antenna. Preferably, when the support member 31 is rotated to the direction in which the wireless signal is strongest, the direction of the surface protrusion 21 of the first conductive layer 2 is the same as the direction of the strongest signal in the wireless signal.
