With the rapid development of communication technology and the wide application of terminal devices, a variety of antennas (such as a high-frequency antenna and a low-frequency antenna) are generally required to be arranged in the terminal devices to meet the increasing use requirements of users.

Generally, the antenna of the terminal device needs to be provided with an independent clearance area, and the lower the operating frequency of the antenna, the larger the clearance area is needed. However, with the development of terminal devices, the space in the terminal device is smaller, that is, the area in the terminal device that can be used as the headroom area of the antenna is smaller, which may result in insufficient headroom area of the low-frequency antenna, thereby affecting the working performance of the low-frequency antenna and further causing poor antenna performance of the terminal device.

An execution main body of the antenna control method provided in the embodiment of the present invention may be the antenna apparatus, the terminal device, or a hardware module and/or a hardware entity (for example, a chip or the like in the antenna apparatus or the terminal device, which can implement the antenna control method) in the antenna apparatus or the terminal device. The specific method can be determined according to actual use requirements, and the embodiment of the invention is not limited. The following takes a terminal device as an example to exemplarily describe the antenna control method provided by the embodiment of the present invention.

The terminal equipment in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.

In the embodiment of the present invention, the antenna apparatus provided in the embodiment of the present invention may be provided with a plurality of high-frequency antennas, so that the antenna apparatus may implement an MIMO technology and a carrier aggregation technology. Wherein the plurality of high frequency antennas may be arranged in an array form.

In the embodiment of the present invention, each high-frequency antenna in the antenna device may have its own independent sine wave analog signal, that is, the antenna device may control the input and output signals of each high-frequency antenna in the antenna device separately.

Illustratively, as shown in fig. 1, at least two high-frequency antennas may be included in the antenna device. Wherein, each high frequency antenna a1 may include a feed point a1 and an element a 2.

The following describes an antenna apparatus, an antenna control method, and a terminal device according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 2, an embodiment of the present invention provides an antenna device 20. The antenna device 20 includes M high-frequency antennas 21, M shutdown modules 22 connected to the M high-frequency antennas 21, and a control module 23 connected to the M shutdown modules 22.

Wherein, M is an integer greater than or equal to 2, and each high-frequency antenna can be respectively connected with a closing module; and the control module can be used for controlling the mutually connected closing module to be electrically connected with or disconnected from the high-frequency antenna.

In the embodiment of the present invention, since signals sent by the multiple high frequency antennas can be fitted to a low frequency signal, when the antenna device needs to send a low frequency signal, the control module may control the at least two interconnected shutdown modules to disconnect from the high frequency antennas, control the at least two high frequency antennas to send signals, and control the at least two high frequency antennas to stop sending signals by controlling the at least two interconnected shutdown modules to electrically conduct with the high frequency antennas, so that signals sent by the multiple high frequency antennas can be fitted to a low frequency signal, and thus the antenna device provided in the embodiment of the present invention can send a low frequency signal, that is, the antenna device provided in the embodiment of the present invention can normally transmit the low frequency signal.

The embodiment of the invention provides an antenna device, which can stop working because the high-frequency antenna is in electric conduction with the high-frequency antenna when a module is closed; under the condition that the closing module is disconnected from the high-frequency antenna, the high-frequency antenna can normally work; and the signals sent by the plurality of high-frequency antennas can be fitted into a low-frequency signal, so that when the antenna device needs to send the low-frequency signal, the control module can be disconnected from the high-frequency antennas by controlling at least two mutually connected closing modules in the antenna device, control the at least two high-frequency antennas to send the signal, and control the at least two high-frequency antennas to stop sending the signal by controlling the at least two mutually connected closing modules to be electrically communicated with the high-frequency antennas, so that the antenna device provided by the embodiment of the invention can normally transmit the low-frequency signal. In addition, since the clearance required when the high-frequency antenna radiates the signal is relatively small, the antenna device can transmit the low-frequency signal through the plurality of high-frequency antennas under the condition that the space in the antenna device is relatively small, namely, the area which can be used as the clearance of the antenna in the antenna device is relatively small, so that the problem that the low-frequency signal cannot be normally transmitted due to insufficient clearance in the antenna device can be avoided, and the performance of the antenna device can be improved.

Optionally, in an embodiment of the present invention, with reference to fig. 2, as shown in fig. 3, each of the M shutdown modules 22 includes a first switch 220 and a wave-absorbing load 221.

The first end 2200 of the first switch 220 is connected to the high-frequency antenna 21, the second end 2201 of the first switch 220 is connected to the first end 2210 of the wave-absorbing load 221, the second end 2211 of the wave-absorbing load 221 is grounded, and the third end 2202 of the first switch 220 is connected to the control module 23.

The control module is specifically used for controlling the closing module connected with each other to be electrically conducted with the high-frequency antenna by controlling the closing of the first switch in the closing module, or the control module is specifically used for controlling the closing module connected with each other to be disconnected with the high-frequency antenna by controlling the opening of the first switch in the closing module.

In the embodiment of the invention, the control module can rapidly control the mutually connected closing module to be electrically conducted with the high-frequency antenna by controlling the closing of the first switch in the closing module, and can rapidly control the mutually connected closing module to be disconnected with the high-frequency antenna by controlling the opening of the first switch in the closing module, so that the high-frequency antenna in the antenna device can be accurately controlled to send signals.

The embodiment of the invention provides terminal equipment which can comprise an antenna device. The antenna device may be the antenna device described above in any of the embodiments of fig. 2 to 3. For the description of the antenna device, reference may be specifically made to the description of the antenna device in the embodiment corresponding to fig. 2 to fig. 3, and for avoiding repetition, the description is not repeated here.

Optionally, the terminal device in the embodiment of the present invention may be a mobile terminal device, and may also be a non-mobile terminal device. For example, the mobile terminal device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, and the like. The method can be determined according to actual use requirements, and the embodiment of the invention is not particularly limited.

The embodiment of the invention provides a terminal device, wherein the high-frequency antenna can stop working under the condition that a closing module is electrically communicated with the high-frequency antenna; under the condition that the closing module is disconnected from the high-frequency antenna, the high-frequency antenna can normally work; and the signals sent by the plurality of high-frequency antennas can be fitted into a low-frequency signal, so that when the antenna device needs to send the low-frequency signal, the control module can be disconnected from the high-frequency antennas by controlling at least two mutually connected closing modules in the antenna device, control the at least two high-frequency antennas to send the signal, and control the at least two high-frequency antennas to stop sending the signal by controlling the at least two mutually connected closing modules to be electrically communicated with the high-frequency antennas, so that the antenna device provided by the embodiment of the invention can normally transmit the low-frequency signal. In addition, since the clearance required when the high-frequency antenna radiates the signal is relatively small, the antenna device can transmit the low-frequency signal through the plurality of high-frequency antennas under the condition that the space in the antenna device is relatively small, namely, the area which can be used as the clearance of the antenna in the antenna device is relatively small, so that the problem that the low-frequency signal cannot be normally transmitted due to insufficient clearance of the low-frequency antennas can be avoided, and the performance of the antenna device can be improved.

As shown in fig. 4, an embodiment of the present invention provides an antenna control method, which is applied to a terminal device including an antenna apparatus provided in the embodiment of the present invention. The method includes S301-S302 described below.

S301, the terminal device obtains a target signal.

S302, the terminal equipment sends the target signal through N high-frequency antennas in M high-frequency antennas in the terminal equipment at the first moment.

Wherein M is more than or equal to N and more than or equal to 2, and M, N are integers.

In this embodiment of the present invention, when the terminal device sends a certain signal (i.e., the target signal), the terminal device may first obtain the target signal, and then send the target signal through the M high-frequency antennas at the first time.

In an embodiment of the present invention, the target signal may be a low frequency signal. It is understood that the terminal device may transmit the low frequency signal through the above-mentioned N high frequency antennas.

Specifically, in the embodiment of the present invention, the terminal device may send a signal through each of the N high-frequency antennas, and the N signals may be fit to a low-frequency signal (i.e., the target signal).

Optionally, in the embodiment of the present invention, the first time may be any time after the terminal device acquires the target signal, and may specifically be determined according to an actual use requirement, which is not limited in the embodiment of the present invention.

Embodiments of the present invention provide an antenna control method, where a terminal device may send a low-frequency signal (i.e., the target signal) through N high-frequency antennas of the M high-frequency antennas, and a headroom required when the high-frequency antennas radiate the signal is relatively small, so that the terminal device may send the low-frequency signal through the multiple high-frequency antennas under a condition that a space in an antenna apparatus is relatively small, i.e., a region that can be used as a headroom region of an antenna in the terminal device is relatively small, so as to avoid a problem that the low-frequency signal cannot be normally sent due to insufficient headroom in the terminal device, thereby improving antenna performance of the terminal device.

Optionally, in this embodiment of the present invention, before the terminal device sends the target signal through N high-frequency antennas of M high-frequency antennas in the terminal device at the first time, the terminal device may first obtain a wavelength (for example, a target wavelength in this embodiment of the present invention) of the target signal, and then determine the N high-frequency antennas from the M high-frequency antennas according to the wavelength. In this manner, after the N high-frequency antennas are determined, the terminal device can transmit the target signal through the N high-frequency antennas at the first timing.

For example, in conjunction with fig. 4, as shown in fig. 5, before S302, the antenna control method provided in the embodiment of the present invention may further include S303 to S304 described below.

S303, the terminal equipment acquires the target wavelength.

The target wavelength may be a wavelength of a target signal.

S304, the terminal device determines N high-frequency antennas from the M high-frequency antennas according to the target wavelength.

In this embodiment of the present invention, when the terminal device needs to transmit the target signal (e.g., a low-frequency signal), after the terminal device acquires the target signal, the terminal device may determine, according to a wavelength of the target signal (i.e., the target wavelength), the number of high-frequency antennas that transmit the target signal, that is, determine the N high-frequency antennas from the M high-frequency antennas.

In the embodiment of the present invention, the relationship between the frequency (denoted by f) and the wavelength (denoted by λ) is:

wherein the unit of frequency is MHz. The relationship between frequency and wavelength can be determined, the higher the frequency, the shorter the wavelength; the lower the frequency is,the longer the wavelength. Therefore, the wavelength of the low-frequency signal is larger than the working wavelength of the high-frequency antenna, so that the terminal equipment can adopt at least two high-frequency antennas to transmit the target low-frequency signal.

Optionally, in this embodiment of the present invention, the terminal device may obtain the target wavelength by obtaining a frequency of the target signal.

In this embodiment of the present invention, when the terminal device sends a certain signal (generally, a digital signal), the terminal device may convert the signal from the digital signal into an analog signal, and then output the analog signal to the feed point of the high-frequency antenna through the radio frequency circuit, after the feed point receives the analog signal, the feed point may output the analog signal to the element of the high-frequency antenna, and then the element may radiate the signal outwards. In this manner, the terminal device can transmit the signal.

For example, the terminal device may convert the digital signal shown in (a) of fig. 6 into an analog signal shown in (b) of fig. 6. The peak-to-average power ratio (PAPR) is a ratio of an amplitude of a waveform of a signal to an effective value of the amplitude, and is a measurement parameter of the waveform, which may also be referred to as a crest factor.

It should be noted that, in the embodiment of the present invention, the larger the value of the peak-to-average ratio is, the better the transmission performance of the antenna is, and the higher the applicable modulation mode is.

Optionally, in the embodiment of the present invention, the N high-frequency antennas may be high-frequency antennas that are disposed adjacent to each other in the terminal device.

In the embodiment of the present invention, on one hand, in the process of operating the high-frequency antenna, other components in the terminal device may generate interference on the N high-frequency antennas, so that by selecting the N high-frequency antennas that are disposed adjacent to each other in the terminal device as the high-frequency antenna for transmitting the target signal, the interference of the other components in the terminal device on the N high-frequency antennas is reduced, and thus the low-frequency signal transmitted by the terminal device can be more stable. On the other hand, N high-frequency antennas which are arranged in adjacent positions in the terminal equipment are selected, so that the terminal equipment can conveniently control the high-frequency antennas. Therefore, the antenna performance of the terminal equipment can be more stable, and the antenna performance of the terminal equipment can be more excellent.

Optionally, in this embodiment of the present invention, the terminal device may divide the target wavelength into multiple segments, and then determine, according to the number of segments of the divided wavelength, the number of high-frequency antennas that transmit the target signal.

Illustratively, in conjunction with fig. 5, as shown in fig. 7, S304 may be implemented by S304a and S304b, which are described below.

S304a, the terminal device divides the target wavelength into N sub-wavelengths.

S304b, the terminal device determines N high-frequency antennas from the M high-frequency antennas according to the N sub-wavelengths.

Each of the N high-frequency antennas may correspond to one sub-wavelength, and a radiation wavelength of the high-frequency antenna corresponding to one sub-wavelength may be greater than or equal to the one sub-wavelength.

In this embodiment of the present invention, after the terminal device obtains the target wavelength, the terminal device may divide the target wavelength into N sub-wavelengths, and determine a high-frequency antenna for each sub-wavelength, so that the N high-frequency antennas may be determined from the M high-frequency antennas.

It should be noted that, in the embodiment of the present invention, the more the number of segments into which the terminal device divides the target wavelength, that is, the more the number of sub-wavelengths into which the terminal device divides the target wavelength, the better the effect of the terminal device in transmitting the target signal, that is, the greater N, the better the effect of the terminal device in transmitting the target signal.

In the embodiment of the present invention, the terminal device may determine the number of segments for dividing the target wavelength, that is, the size of N, according to the size of the target wavelength.

Optionally, in the embodiment of the present invention, a rule for wavelength division may be preset in the terminal device. Specifically, a plurality of bands and the number of segments of each band corresponding to each band may be preset in the terminal device, and after the terminal device determines the target wavelength, the terminal device may determine the band to which the target wavelength belongs, and then may determine the number of segments of the target wavelength, that is, may determine the N sub-wavelengths.

Of course, in actual implementation, the terminal device may also divide the target wavelength in any other possible manner, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

For example, in the embodiment of the present invention, the terminal device may divide the target wavelength into 4 segments (N ═ 4), that is, the terminal device may divide the target wavelength into 4 sub-wavelengths. In this way, the terminal device can determine one high-frequency antenna for each of the 4 sub-wavelengths, and thus can determine 4 high-frequency antennas.

In the embodiment of the present invention, the terminal device may determine the number of high frequency antennas transmitting the target signal by the number of sub-wavelengths into which the target wavelength is divided, so that the N high frequency antennas may be accurately determined from the M high frequency antennas.

Optionally, in this embodiment of the present invention, since each of the N high-frequency antennas corresponds to one sub-wavelength, the terminal device may radiate a signal of one sub-wavelength through each of the N high-frequency antennas at a first time, so that the terminal device may accurately transmit the target signal.

Illustratively, in conjunction with fig. 7, as shown in fig. 8, the above S302 may be specifically implemented by the following S302 a.

S302a, the terminal device transmits a target signal by radiating a sub-wavelength signal through each of the N high-frequency antennas at a first time.

In this embodiment of the present invention, the terminal device may radiate a sub-wavelength signal corresponding to each of the N high-frequency antennas through the N high-frequency antennas at a first time, that is, the terminal device radiates N sub-wavelength signals through the N high-frequency antennas at the first time, so as to transmit the target signal.

It should be noted that, in the embodiment of the present invention, since the wavelength of the target signal may be divided into multiple segments, that is, the wavelength of the target signal may be divided into multiple sub-wavelengths (that is, the N sub-wavelengths), the signals of the N sub-wavelengths may be synthesized into the target signal.

In this embodiment of the present invention, the terminal device may control the N high-frequency antennas to operate simultaneously at the first time.

Of course, in actual implementation, the terminal device may also control the N high-frequency antennas to transmit the target signal in any other possible manner, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

For ease of understanding, the following description will first exemplify the operation principle of the terminal device radiating low-frequency signals through the low-frequency antenna.

For example, as shown in fig. 9, when the terminal device sends a low-frequency signal through the low-frequency antenna, the terminal device may output the low-frequency signal after digital-to-analog conversion to the feed point 41 of the low-frequency antenna, and the feed point 41 of the low-frequency antenna may output the low-frequency signal to the element 42 of the low-frequency antenna, so that the element 42 of the low-frequency antenna may radiate the low-frequency signal outwards, that is, the terminal device may send the low-frequency signal through the low-frequency antenna. Among them, 43 in fig. 9 is used to indicate a current flow direction when the low frequency antenna radiates a low frequency signal, and 44 in fig. 9 is used to indicate a radiation effect when the low frequency antenna radiates a low frequency signal.

In this embodiment of the present invention, the terminal device may control each of the N high frequency antennas to radiate a sub-wavelength signal, and the signals radiated by the plurality of high frequency signals may be fitted to a low frequency signal, for example, the target signal.

The following is an exemplary description of the radiation effects of one high-frequency antenna radiation signal and a plurality of high-frequency antenna radiation signals, respectively.

Illustratively, as shown in fig. 10, the terminal device may control the high-frequency antenna 211 to radiate a signal of one sub-wavelength. Wherein 51 in fig. 10 is used to indicate the current flow direction of the signal of the sub-wavelength radiated by the high- frequency antenna 211, and 52 in fig. 10 is used to indicate the radiation effect of the signal of the sub-wavelength radiated by the high-frequency antenna 211.

As another example, as shown in fig. 11, the terminal device may control the high-frequency antenna 211 and the high-frequency antenna 212 to radiate signals of one sub-wavelength, respectively. Here, 53 in fig. 11 indicates a current flow direction in which the high-frequency antenna 212 radiates a signal of the sub-wavelength, and 54 in fig. 11 indicates a radiation effect in which the high-frequency antenna 211 and the high-frequency antenna 212 radiate signals of one sub-wavelength, respectively.

As another example, as shown in fig. 12, the terminal device may control the high-frequency antenna 211, the high-frequency antenna 212, and the high-frequency antenna 213 to radiate signals of one sub-wavelength, respectively. In fig. 12, 55 indicates the current flow direction in which the high-frequency antenna 213 radiates signals of the sub-wavelength, and 56 indicates the radiation effect in which the high-frequency antenna 211, the high-frequency antenna 212, and the high-frequency antenna 213 radiate signals of one sub-wavelength, respectively.

As another example, as shown in fig. 13, the terminal device may control n high-frequency antennas (e.g., the high-frequency antenna 211, the high-frequency antenna 212, the high-frequency antenna 213, up to the high-frequency antenna 21n, and the like shown in fig. 13) to radiate signals of one sub-wavelength, respectively. In fig. 13, 57 indicates a current flow direction in which the high-frequency antenna 21n radiates a signal of one sub-wavelength, and 58 indicates a radiation effect in which the high-frequency antenna 211, the high-frequency antenna 212, and the high-frequency antenna 213 radiate a signal of one sub-wavelength, respectively, until the high-frequency antenna 21n radiates a signal of one sub-wavelength.

In the embodiment of the present invention, as can be seen from fig. 10 to 13, the effect of the low frequency signal transmitted by the terminal device is closer to the effect of the low frequency signal transmitted by the terminal device through the low frequency antenna as the number of high frequency antennas participating in the radiation of the low frequency signal (i.e., the target signal) is larger. Thus, the greater the number of high frequency antennas (i.e., the greater N) participating in the radiation of the low frequency signal, the better the effect of the low frequency signal transmitted by the terminal device.

Optionally, in this embodiment of the present invention, after the N high-frequency antennas finish transmitting the target signal, the terminal device may turn off the N high-frequency antennas, that is, control the N high-frequency antennas to stop working.

Optionally, in the embodiment of the present invention, the terminal device may turn off the N high-frequency antennas in two ways, where the two ways may be a first way and a second way, and the two ways are specifically described as examples below.

The first method is as follows: and at a second moment after the first moment, the terminal equipment simultaneously turns off the N high-frequency antennas.

The second method comprises the following steps: and the terminal equipment turns off the N high-frequency antennas in sequence from a third time after the first time.

In the embodiment of the present invention, the above-described "mode one" is first exemplarily described below.

For example, with reference to fig. 4, as shown in fig. 14, after S302, the antenna control method according to the embodiment of the present invention may further include S305 described below.

And S305, at a second moment after the first moment, the terminal equipment simultaneously turns off the N high-frequency antennas.

In the embodiment of the present invention, for the "mode one", the terminal device may control each of the N high-frequency antennas to operate for the same time duration, so as to control signals sent by the N high-frequency antennas to be synthesized into the target signal.

In an embodiment of the present invention, the working duration of the N high-frequency antennas may be a difference between the second time and the second time.

It should be noted that, in the embodiment of the present invention, the terminal device may control the current flow direction of the high-frequency antenna and the radiation effect of the high-frequency antenna by controlling the operating time lengths of the N high-frequency antennas.

Optionally, in this embodiment of the present invention, the second time may be determined according to performance of each of the N high-frequency antennas.

In the embodiment of the present invention, after the terminal device sends the target signal through the N high-frequency antennas at the first time, the terminal device may simultaneously turn off the N high-frequency antennas at a second time, that is, the terminal device controls the N high-frequency antennas to stop working at the same time, so that the terminal device can control the high-frequency antennas conveniently.

In the embodiment of the present invention, the above-described "means two" will be described below by way of example.

For example, in conjunction with fig. 4, as shown in fig. 15, after S302, the antenna control method provided in the embodiment of the present invention may further include S306.

And S306, from the third moment after the first moment, the terminal equipment closes the N high-frequency antennas in sequence.

In the embodiment of the present invention, as for the "mode two", after the terminal device transmits the target signal through the N high-frequency antennas at the first time, the terminal device may sequentially turn off the N high-frequency antennas from a third time after the first time, so as to ensure that signals transmitted by the N high-frequency antennas can be synthesized into the target signal.

In this embodiment of the present invention, in order to increase the peak-to-average ratio when the terminal device transmits the target signal through the N high-frequency antennas, the terminal device may sequentially control the N high-frequency antennas to stop working, that is, the terminal device sequentially turns off the N high-frequency antennas.

Optionally, in the embodiment of the present invention, the step S306 may be specifically implemented by the step S306a described below.

S306a, the terminal device turns off a high-frequency antenna every preset time period from the third time along the target direction.

The target direction may be a direction opposite to a radiation direction of the antenna device in the terminal device.

In this embodiment of the present invention, the terminal device may turn off one high-frequency antenna every predetermined time period from the third time point in a direction (i.e., the target direction) opposite to the radiation direction of the antenna apparatus in the terminal device, so as to turn off the N high-frequency antennas.

It should be noted that, in the embodiment of the present invention, the radiation direction of the antenna device in the terminal device may be a current direction of the antenna device in the terminal device.

In the embodiment of the present invention, the terminal device may control the high-frequency antenna at the end of the current flow to stop working according to the current flow direction when the N high-frequency antennas transmit signals, and then sequentially turn off the N high-frequency antennas according to the reverse direction of the current flow direction, so that the high-frequency antennas may generate a larger peak-to-peak value when working, that is, the amplitude of the signal may be increased, thereby increasing the peak-to-average ratio.

Illustratively, as shown in fig. 16, a simplified diagram of the peak-to-average ratio is provided for the embodiment of the present invention. 61 in fig. 16 is configured to instruct the terminal device to control the N high-frequency antennas to stop operating simultaneously, where the N high-frequency antennas transmit peak-to-average power ratio curves of the target low-frequency signal; fig. 16 is a graph 62 for indicating that when the terminal device controls two high-frequency antennas to stop working in sequence, the two high-frequency antennas transmit the peak-to-average ratio curve of the target low-frequency signal; fig. 63 is a graph 63 for instructing the terminal device to control 3 high-frequency antennas to stop working in sequence, where the 3 high-frequency antennas transmit the peak-to-average ratio curve of the target low-frequency signal; fig. 16 is 64 for instructing the terminal device to control 4 high-frequency antennas to stop working sequentially, where the 4 high-frequency antennas transmit the peak-to-average ratio curve of the target low-frequency signal; fig. 16 is 65 a diagram for instructing the terminal device to control 5 high-frequency antennas to stop working in sequence, where the 5 high-frequency antennas transmit the peak-to-average ratio curve of the target low-frequency signal; fig. 16 is a graph 66 for instructing the terminal device to control 6 high-frequency antennas to stop working in sequence, where the 6 high-frequency antennas transmit the peak-to-average ratio curve of the target low-frequency signal; 67 in fig. 16 is used to instruct the terminal device to control 7 high-frequency antennas to stop operating sequentially, and the 7 high-frequency antennas transmit the peak-to-average ratio curve of the target low-frequency signal.

As can be seen from comparison of the respective peak-to-average ratio curves in fig. 16, when the number of the high-frequency antennas participating in the transmission of the target signal is larger, the terminal device controls the high-frequency antennas to stop operating in sequence, so that the effect of increasing the peak-to-average ratio is better.

In the embodiment of the present invention, the terminal device may sequentially turn off the N high-frequency antennas from the third time of the first time, so as to improve a peak-to-average ratio of a target signal transmitted by the terminal device through the N high-frequency antennas, so as to improve an effect of the terminal device transmitting the target signal through the N high-frequency antennas, and further improve antenna performance of the terminal device.

Optionally, in the embodiment of the present invention, the terminal device may control the N high-frequency antennas to stop working in a manner of absorbing electromagnetic waves, that is, the terminal device may close the N high-frequency antennas in a manner of absorbing electromagnetic waves.

Optionally, in this embodiment of the present invention, the terminal device may control the N high-frequency antennas to stop working by controlling the N first loads to respectively absorb the electromagnetic waves emitted by one high-frequency antenna.

Optionally, in this embodiment of the present invention, each high-frequency antenna in the terminal device may be connected to a first load through a switch. The terminal equipment can trigger the first load to absorb electromagnetic waves on the high-frequency antenna by controlling the conduction of the switch arranged between the first load and the high-frequency antenna, so that the high-frequency antenna is controlled to stop working.

In actual implementation, of course, the terminal device may also turn off the N high-frequency antennas in any other possible manner, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

In the embodiment of the invention, the terminal equipment can rapidly control the N high-frequency antennas to stop working in a mode of absorbing electromagnetic waves.

In specific implementation, the antenna control method shown in each of the above drawings may also be implemented by combining any other drawings that may be combined, which are illustrated in the above embodiments, and are not described herein again.
