The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

With the development of communication technology, more and more antennas are required for electronic devices such as mobile phones. Electromagnetic waves exist in the communication antenna, and an induction electromagnetic field is generated in a human body under the action of an external electromagnetic field. Therefore, when the user uses the communication device, the user may interfere with the communication antenna by holding the communication device with hands or hands, which may cause abnormality or missing of the communication signal.

An electromagnetic wave absorption ratio detector is generally disposed in a mobile phone for detecting whether a human body approaches an electronic device. However, the current electromagnetic wave absorption ratio detector can only be used for detecting whether a human body approaches to the electronic equipment, and cannot judge specific operation postures such as holding by hands or holding by hands.

To overcome the problems in the related art, the present disclosure provides a terminal.

The terminal of the present disclosure includes: a metal frame; the antennas are electrically connected to the metal frame and correspondingly form a plurality of antenna areas; the capacitance value sensor is provided with a capacitance value detection end which is arranged in the antenna area.

The terminal of this disclosure is including one or more capacitance value sensor, and capacitance value sensor is provided with a plurality of capacitance value detection ends, and the capacitance value detection end sets up in the antenna area for whether the detection antenna area is sheltered from by the object. By the arrangement, whether the antenna area is blocked by an object or not can be accurately detected by the capacitance value detection end arranged in the antenna area. If it is detected that the antenna area is blocked by an object, the capacitance detection end can transmit the signal to the capacitance sensor, and the signal is transmitted to a corresponding control center by the capacitance sensor to control the antennas in other areas to perform communication work. By means of the arrangement, the antenna area which is shielded by the object on the terminal can be judged, so that the terminal can switch the communication antenna to the antenna which is not shielded by the object, stability of communication signals is guaranteed, and use experience of a user is improved.

Fig. 1 is a schematic diagram illustrating a structure of a terminal according to an exemplary embodiment. As shown in fig. 1, the terminal of the present disclosure includes: a metal bezel 400, a plurality of antennas, and a capacitance sensor 200.

In the present disclosure, the antennas are electrically connected to the metal frame 400, and a plurality of antennas correspondingly form a plurality of antenna regions.

As shown in fig. 1, the present disclosure may include 10 antennas connected with a metal bezel 400 to form a first antenna region 101, a second antenna region 102, a third antenna region 103, a fourth antenna region 104, a fifth antenna region 105, a sixth antenna region 106, a seventh antenna region 107, an eighth antenna region 108, a ninth antenna region 109, and a tenth antenna region 110, respectively.

Generally, the antenna is connected to the metal frame, and may be connected to the antenna by disposing a grounding point and a feeding point on the metal frame. According to the antennas with different purposes, the required frequency bands are different, the occupied space of the antennas for receiving different frequency bands is different, and the space occupied by each antenna is the antenna area of the antenna.

It should be noted that the antenna space is only used for illustrating the spatial position, and there is no physical structure, and all the antenna spaces are illustrated by dotted lines in the drawings.

In exemplary embodiments of the present disclosure, the plurality of antennas form a MIMO array.

Specifically, MIMO (Multiple-Input Multiple-Output) technology is to use Multiple transmitting antennas and Multiple receiving antennas at a transmitting end and a receiving end, respectively, so that signals are transmitted and received through the Multiple antennas at the transmitting end and the receiving end, thereby improving communication quality. The multi-antenna multi-transmission multi-receiving system can fully utilize space resources, realizes multi-transmission and multi-reception through a plurality of antennas, can improve the system channel capacity by times under the condition of not increasing frequency spectrum resources and antenna transmitting power, and has obvious advantages.

The transmitting terminal maps the data signals to be transmitted to a plurality of antennas through space-time mapping and transmits the data signals, and the receiving terminal performs space-time decoding on the signals received by each antenna so as to recover the data signals transmitted by the transmitting terminal.

As shown in fig. 1, taking ten antennas as an example, the MIMO array antenna of the present disclosure may employ a spatial diversity technique. Space diversity refers to transmitting signals with the same information through different paths by using multiple transmitting antennas, and obtaining multiple independently fading signals of the same data symbol at a receiver end, thereby obtaining reception reliability improved by diversity. For example, in a slow rayleigh fading channel, n receiving antennas are used for one transmitting antenna, and a signal is transmitted through n different paths. If the fading between the antennas is independent, a maximum diversity gain of n can be achieved. For the transmit diversity technique, the gains of multiple paths are also used to improve the reliability of the system. In a system with m transmit antennas and n receive antennas, if the path gain between antenna pairs is independent uniformly distributed rayleigh fading, the maximum diversity gain that can be obtained is mn. Space diversity techniques commonly used in MIMO systems are mainly Space Time Block Code (STBC) and beamforming techniques.

At present, with the coming of the 5G era, more and more antennas are needed on terminals such as mobile phones, and the requirement of the 5G antennas can be met by adopting the MIMO array antenna.

As shown in fig. 1, in the present disclosure, at least one long side of the terminal is provided with an antenna. The terminal can be used by users in various modes, and the terminal can be held vertically or horizontally. The multifunctional pen can be held vertically when using communication and other functions, and can be held horizontally when playing games or playing videos.

When the terminal is operated in a lateral grip, the antenna of the short side of the terminal is often shielded. This above-mentioned setting of disclosure can ensure when the antenna of the minor face at terminal is often sheltered from, also be provided with the antenna on the long limit at terminal, the terminal can switch to the antenna that sets up on the long side of terminal and communicate, ensures that the passage at terminal is not interrupted. It is understood that the long side in the present disclosure is a longer side of the sides of the mobile terminal surrounding the display area.

As in the present disclosure, the capacitance sensor 200 is provided with a plurality of capacitance detection terminals, and the capacitance detection terminals are disposed in the antenna area.

As shown in fig. 1, the capacitance sensor 200 may be provided with four capacitance detection terminals, each of which is disposed in a different antenna region.

As shown in fig. 1, the capacitance sensor 200 has a first capacitance detecting terminal 201, a second capacitance detecting terminal 202, a third capacitance detecting terminal 203 and a fourth capacitance detecting terminal 204.

Furthermore, the first capacitance detecting terminal 201 is disposed in the first antenna region 101 and is close to the metal frame within the first antenna region 101. Correspondingly, the second capacitance detecting terminal 202 is disposed in the second antenna region 102 and is close to the metal frame in the second antenna region 102. The third capacitance detecting terminal 203 is disposed in the third antenna region 103 and is close to the metal frame in the range of the third antenna region 103.

Taking the first capacitance detecting terminal as an example, the first capacitance detecting terminal 201 is used for detecting whether an object is blocked at the first antenna area 101. If the first capacitance detecting terminal 201 detects that an object is blocked at the first antenna area 101, a signal is sent to the capacitance sensor 200.

After receiving the signal, the capacitance sensor 200 may transmit the signal to the control unit 300 inside the terminal, and the control unit 300 operates another antenna to start communication operation, thereby avoiding a lack or an abnormality of the communication signal.

Specifically, taking ten antennas as an example, for example, if the user holds the terminal in a hand-held posture in a MIMO array mode, the communication between the two antennas in the seventh antenna area 107 and the eighth antenna area 108 may be interrupted.

In the MIMO array antenna, ten antennas receive signals, and accordingly, the signals received by the ten antennas need to be decoded completely to acquire information. If the communication between two antennas is interrupted and the signal cannot be received, the received signal will not be complete.

Fig. 2 is a schematic diagram illustrating a structure of a terminal according to another exemplary embodiment. As shown in fig. 2, in the exemplary embodiment of the present disclosure, one capacitance value detection terminal is disposed in each antenna area.

In the present disclosure, the capacitance sensor 200 may be provided with ten capacitance detection terminals, which are a fifth capacitance detection terminal 205, a sixth capacitance detection terminal 206, a seventh capacitance detection terminal 207, an eighth capacitance detection terminal 208, a ninth capacitance detection terminal 209 and a tenth capacitance detection terminal 210.

In this disclosure, each capacitance detection end is disposed in each antenna area and is close to a metal frame in the corresponding antenna area, so that the capacitance sensor 200 can determine whether each antenna area is shielded by an object, and then the terminal can switch to start working of an antenna which is not shielded by the object.

In an exemplary embodiment of the present disclosure, the capacitance value detecting terminal is configured to detect an electromagnetic wave absorption ratio and transmit an electromagnetic wave absorption ratio signal to the capacitance value sensor.

Sar (specific Absorption rate) is an electromagnetic wave energy Absorption ratio of a terminal such as a mobile phone or a wireless product.

Under the action of the external electromagnetic field, an induction electromagnetic field is generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate electric currents, resulting in absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterize this physical process. SAR has the meaning of the electromagnetic power absorbed or consumed by a unit mass of human tissue.

The SAR value generally refers to heat energy generated by electromagnetic waves in a mobile phone product, and is measurement data which affects a human body.

In the disclosure, the capacitance detection end is configured to detect the electromagnetic wave absorption ratio, and whether an object is shielded in a corresponding antenna area can be accurately judged by using the principle that human tissues dissipate electromagnetic energy.

In addition, since the electromagnetic wave of the communication antenna has a certain influence on the human body, for example, the SAR value indicates how much the thermal energy of the mobile phone has an influence on the human body, and the larger the value is, the larger the influence on the human body is, and the smaller the influence is. The detection data of the capacitance value detection end can be utilized, when an object is shielded, the electromagnetic wave of the terminal is controlled within a certain range, and the influence on the human body is reduced to the minimum.

With respect to the radiation SAR (Specific Absorption Rate) of a mobile phone to a human body, regulations have been made in the United states and Europe, and the U.S. standard is 1.6W/kg (1 g) and the European standard is 2.0W/kg (10 g). The standard safety value of mobile phones published by the federal commission of the united states (FCC) is 1.6, and therefore, mobile phones are products within the standard safety value as long as the SAR value of the mobile phones is below 1.6.

According to the embodiment, in the present disclosure, it is not only possible to detect whether the antenna area at the corresponding position is blocked by an object by using the capacitance detection end, and then the terminal switches the antenna. And when the shielding of an object is detected, the electromagnetic wave of the terminal is reduced, and the influence on a human body is reduced. By means of the arrangement, the use feeling of a user is improved, and the competitiveness of a product is improved.

It should be noted that the capacitance value detection terminal of the present disclosure is not limited to be used for detecting the electromagnetic wave absorption ratio. In some embodiments, the capacitance value detection terminal may be further configured to detect an ultrasonic absorption ratio.

For example, in an embodiment, the capacitance value detection end may be further used to transmit ultrasonic waves and receive reflected ultrasonic waves at the same time, and whether an object blocks an antenna area may also be detected by using the principle that a human body absorbs ultrasonic waves.

In exemplary embodiments of the present disclosure, upper and lower sides of the capacitance value detecting terminal are set as clearance areas through which no current passes. Due to the arrangement, the interference of the electromagnetic field generated by the current passing through the electromagnetic field to the electromagnetic field transmitted and received by the capacitance value detection end can be avoided, and the capacitance value detection end can accurately judge whether an object is shielded in a certain antenna area.

In an exemplary embodiment of the present disclosure, the capacitance value detecting terminal is sheet-shaped. The capacitance value detection end is arranged in a sheet shape, and can also detect in a larger range, namely the detection range of the capacitance value detection end is enlarged.

In the present disclosure, the setting size of the capacitance detection end may be adapted to the corresponding antenna area, so as to cover the corresponding antenna area as much as possible. Therefore, the detection area can be further enlarged, the detection is carried out in the whole antenna area range, and the probability of accurately detecting whether the human body is close to the antenna is increased.

The capacitance value detection end of this disclosure can be metal, and the ductility of metal is strong, and has certain intensity, can suspend and set up in the air. Therefore, the device is convenient to set, a supporting device can be omitted, and materials and a manufacturing process are saved. And may be electrically connected to the metal bezel.

In some embodiments, the capacitance value detecting terminal may be formed of a metal sheet.

In an exemplary embodiment of the present disclosure, the capacitance sensor may be electrically connected to the capacitance detecting terminal through a microstrip line.

Microstrip lines are microwave transmission lines consisting of a single conductor strip supported on a dielectric substrate. The planar structure transmission line is suitable for manufacturing microwave integrated circuits. Compared with a metal waveguide, the waveguide has the advantages of small volume, light weight, wide use frequency band, high reliability, low manufacturing cost and the like; but the loss is slightly larger and the power capacity is small. The dielectric substrate is made of a material with high dielectric constant and low microwave loss. The conductor should have the characteristics of high conductivity, good stability, strong adhesion with the substrate, and the like.

Utilize microstrip line connection capacitance value sensor and capacitance value sense terminal, can be so that walk the line thinner, shared space is less to can be used for setting up the capacitance value sense terminal with more space, make the testing result more accurate.

In an exemplary embodiment of the present disclosure, the metal bezel is a middle bezel of the terminal. Generally, the middle frame is used as an existing device of the terminal, and the metal frame is used for arranging the antenna and the capacitance value detection end, so that the detection requirement can be completed, and the increase of manufacturing cost caused by newly added components can be avoided.

Moreover, the middle frame is generally positioned outside the terminal, so that the requirements of antenna clearance and capacitance value detection end clearance can be met.

As shown in fig. 2, in an exemplary embodiment of the present disclosure, the terminal further includes a controller, the capacitance sensor being electrically connected to the controller; the controller is configured to receive a signal of the capacitance sensor and switch an operating state of the antenna.

In the present disclosure, the controller may be a control chip inside the terminal, or may be a control circuit on a circuit board. The controller can receive the signal and send a corresponding control signal according to the received signal so as to control the starting or the closing of various components on the terminal.

In the disclosure, when the capacitance detection end detects that the capacitance reaches a certain value and determines that the object is blocked, a signal is sent to the capacitance sensor. The capacitance value sensor receives the signal and then sends the signal to the controller. And after receiving the signal, the controller sends a control signal to the antenna management module, and the antenna management module switches the antenna to carry out communication.

Taking MIMO array antennas as an example, when a user holds the mobile phone, two of the ten antennas are blocked from communication. The controller may switch the antennas to switch the ten-array antenna to an antenna having the remaining eight antennas as the eight-array antenna as the communication antenna. By means of the arrangement, when part of the antennas cannot communicate, the terminal can switch other antennas, and normal communication of the terminal is guaranteed. The communication quality of the terminal is improved.

Fig. 3 is a schematic diagram illustrating a structure of a terminal according to another exemplary embodiment. As shown in fig. 3, in an exemplary embodiment of the present disclosure, the terminal may further include a plurality of capacitance value sensors.

As shown in fig. 3, the terminal of the present disclosure may include two capacitance value sensors, a first capacitance value sensor 211 and a second capacitance value sensor 220, respectively.

The first capacitance sensor 211 is disposed near the top of the terminal and the second capacitance sensor 220 is disposed near the bottom of the terminal.

Such setting is favorable to setting up the capacitance value sensor that enough detection has the object to shelter from in a plurality of antenna area at the complicated inside line setting in terminal. Generally, a terminal has a plurality of electronic components and various complex circuits inside.

The capacitance sensors are arranged at the top and the bottom of the terminal respectively, so that the wiring difficulty can be reduced, and the wiring quality is ensured. The stability of the internal circuit of the terminal is maintained, and the capacitance sensor and the capacitance detection end are effectively used.

Fig. 4 is a schematic diagram illustrating a structure of a terminal according to another exemplary embodiment. As shown in fig. 4, the present disclosure also provides a terminal, including: a metal bezel 400, a plurality of antennas, and a capacitance sensor 200.

In the present disclosure, the antennas are electrically connected to the metal frame 400, and a plurality of antennas correspondingly form a plurality of antenna regions.

As shown in fig. 4, the present disclosure may include 10 antennas connected with a metal bezel 400 to form a first antenna region 101, a second antenna region 102, a third antenna region 103, a fourth antenna region 104, a fifth antenna region 105, a sixth antenna region 106, a seventh antenna region 107, an eighth antenna region 108, a ninth antenna region 109, and a tenth antenna region 110, respectively.

In the present disclosure, the metal frame in the antenna area is electrically connected to the capacitance sensor, and the metal frame in the corresponding antenna area is configured as a capacitance detection end to detect whether there is an object shelter in the corresponding antenna area.

As shown in fig. 4, the metal frame in each antenna area is electrically connected to the capacitance sensor 200, and the metal frame is used as a capacitance detecting end of the capacitance sensor 200 to detect whether the corresponding antenna area is blocked by an object.

According to the arrangement, the metal frame is used as the capacitance value detection end of the capacitance value sensor, one part in the terminal is used for playing two functions, and raw materials of the terminal production process can be saved.

In addition, because the independently arranged capacitance value detection end is omitted, the space for placing the independently arranged capacitance value detection end is not required to be reserved in the terminal, so that the internal space of the terminal is saved, and the terminal is light and thin.

In the present disclosure, the capacitance Sensor may be referred to as Sar Sensor, the capacitance detection terminal may be referred to as pad, and the controller may be referred to as cotrol.

The Sar sensor is designed on the mobile equipment, when the hand holding is detected, an antenna of a certain communication system can be switched, for example, when the Sar is designed at the top end of the mobile equipment, when gsm conversation is carried out, if the Sar does not detect that the top is close to the Sar, the upper antenna is opened, because the lower antenna can not be held by the hand to communicate at the moment; when the upper antenna is detected to be close to the lower antenna, the upper antenna is closed, and the lower antenna is used for communication;

with the arrival of 5g, the middle frame of the mobile device is completely provided with the antenna in one circle, so that the switching of different antennas in one circle of the middle frame can be realized by designing the double sar sensors from top to bottom.

If the mobile device is provided with n antennas, based on the current sar, the output of the sar is set to be n detection pads, the detection of each sar and one of the antennas or the adjacent antenna multiplexes the metal of the mobile device frame, the internal part of the sar codes different detections, for example, a first detection antenna area corresponds to a first detection pin, a certain pin detects the capacitance change, the coded capacitance identification area sends the capacitance change identified by the certain area to a control center through a communication protocol, the control center can be that the sar is directly connected with a modem core through a sensor core or a communication interface, the control center knows the information port, and the current communication antenna is switched to the antenna which is not shielded.

When the mobile equipment is in communication, all pads are in operation, when no object approaches, the parasitic capacitance is Cx, when the object approaches, the object serves as a second polar plate Cp, the detection approach threshold is Ct, when Cp > Ct, the object is judged to approach, according to the fact that the capacitance of the pad exceeds the threshold, the coded detection pad is sent to a control through a communication protocol sar, the control identifies the corresponding antenna area to be accessed according to the coding, and then the communication is continued through other multiplexing antennas of the communication system.

Generally, the detection pad area is empty, that is, there is no ground area above and below the main board in the area, only the detection pad is empty, the routing needs to be as thin as possible, and the area of the pad is as large as possible.

According to the embodiment, the scheme can optimize the experience during communication, avoid the shielded antenna signal from deteriorating and optimize the experience of the terminal equipment.
