Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a schematic diagram of an internal structure of an electronic device in one embodiment. As shown in fig. 1, the electronic device includes a processor and a memory connected by a system bus. Wherein, the processor is used for providing calculation and control capability and supporting the operation of the whole electronic equipment. The memory may include a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The computer program can be executed by a processor to implement an antenna module switching method provided in the following embodiments. The internal memory provides a cached execution environment for the operating system computer programs in the non-volatile storage medium. The electronic equipment can be various mobile phones, computers, portable equipment and the like.
The electronic equipment comprises a millimeter wave sensor, a first antenna module and a second antenna module. As shown in fig. 2, the millimeter wave sensor includes a microstrip filter 200 including an artificial surface plasmon 210 and a defect cell 220, and further includes an input terminal 230, an output terminal 240, and a medium 250 (load bearing function). In fig. 2, a periodic rectangular metal sheet with a long length forms surface artificial surface plasmons, and a rectangular metal sheet with a short length is called a defect unit, and mainly plays a role in introducing a band-stop effect into a transmission characteristic curve. The millimeter wave sensor is arranged in the electronic equipment shell, the millimeter wave sensor is attached to the inner wall of the electronic equipment shell, the distance between the millimeter wave sensor and the first antenna module is smaller than a preset distance, and the distance between the millimeter wave sensor and the second antenna module is larger than or equal to the preset distance.
Fig. 3 is a flowchart of an antenna module switching method in an embodiment, which is applied to an electronic device, and as shown in fig. 3, the antenna module switching method includes steps 320 to 340.
And 320, detecting whether the outer wall corresponding to the inner wall of the electronic equipment shell attached with the millimeter wave sensor is in a shielding state or not through the millimeter wave sensor.
Because the metal layer in the millimeter wave sensor comprises the microstrip filter, the microstrip filter comprises the artificial surface plasmon and the defect unit, and the defect unit mainly plays a role in introducing a band elimination effect into a transmission characteristic curve. When the outer wall that the electronic equipment shell inner wall that millimeter wave sensor laminated corresponds was in the state of sheltering from like this, then after millimeter wave sensor launches the millimeter wave signal input of different frequencies in proper order to the metal level, the transmission coefficient of the millimeter wave signal that is close specific frequency can be less than the transmission coefficient of the millimeter wave signal of other frequencies far away. When different media are attached to the outer wall corresponding to the inner wall of the electronic device shell to which the millimeter wave sensor is attached, the transmission coefficients of millimeter wave signals with different frequencies, which are sequentially transmitted by the millimeter wave sensor, input into the metal layer are affected due to the different dielectric constants of the different media. The transmission coefficient is the attenuation coefficient of the signal during transmission. Therefore, after the signal processing chip receives the output millimeter wave signal, the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient is analyzed to determine whether the frequency is consistent with the preset frequency. The preset frequency is the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient when different media are attached to the outer wall corresponding to the inner wall of the electronic equipment shell to which the millimeter wave sensor is attached.
And 340, when the outer wall corresponding to the inner wall of the electronic equipment shell attached with the millimeter wave sensor is detected to be in a shielding state, switching to a second antenna module for communication.
If the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient is analyzed to be consistent with the preset frequency, the outer wall corresponding to the inner wall of the electronic equipment shell attached to the millimeter wave sensor is in a shielding state. When only the first millimeter wave sensor is arranged in the electronic equipment, because the distance between the first antenna module and the first millimeter wave sensor is smaller than the preset distance, the first antenna module can be shielded, the antenna module is shielded to influence the communication quality, and therefore the communication is carried out by switching to the second antenna module. The distance between the second antenna module and the first millimeter wave sensor is larger than or equal to the preset distance, so that the second antenna module is not shielded and the communication quality is not influenced.
In the embodiment of the application, because the millimeter wave sensor comprises the microstrip filter, the microstrip filter comprises the artificial surface plasmon and the defect unit, and the defect unit mainly plays a role in introducing a band elimination effect into a transmission characteristic curve. When the outer wall that the electronic equipment shell inner wall that millimeter wave sensor was laminated corresponds was in the state of sheltering from like this, then the millimeter wave sensor launches the millimeter wave signal of different frequencies in proper order and inputs to the microstrip filter after, and the transmission coefficient of the millimeter wave signal that is close specific frequency after the filtering can be less than the transmission coefficient of the millimeter wave signal of other frequencies far away. Thereby, detect out that the outer wall that the electronic equipment shell inner wall that first millimeter wave sensor laminated corresponds is in and shelters from the state, because the distance between first antenna module and the first millimeter wave sensor is less than and predetermines the distance, so first antenna module also can be sheltered from to switch over to the second antenna module and communicate. The distance between the second antenna module and the first millimeter wave sensor is larger than or equal to the preset distance, so that the second antenna module is not shielded and the communication quality is not influenced. Therefore, the antenna module can be switched in time for communication, and the communication quality of the electronic equipment is improved.
In one embodiment, as shown in fig. 4, step 320 of detecting, by the millimeter wave sensor, whether an outer wall corresponding to an inner wall of the electronic device housing area attached to the millimeter wave sensor is in a shielding state includes:
In step 324, millimeter wave signals with different frequencies are output after being filtered by artificial surface plasmons and defect units on the microstrip filter, and the transmission coefficient of the output millimeter wave signals with each frequency is calculated.
In step 326, the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient is obtained as the target frequency.
Specifically, the millimeter wave sensor may be connected to the radio frequency generator, so that millimeter wave signals with different frequencies transmitted by the radio frequency transmitter may be input to the input end of the microstrip filter. Millimeter wave signals with different frequencies are output from an output end after being filtered by artificial surface plasmons and defect units on the microstrip filter, a signal processing chip calculates transmission coefficients of the output millimeter wave signals with different frequencies, the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient at the moment is analyzed, and the frequency of the millimeter wave signal is taken as a target frequency.
And then, comparing the target frequency with a preset frequency, and when the difference value between the target frequency and the preset frequency is smaller than a preset threshold value, detecting that the outer wall corresponding to the inner wall of the electronic equipment shell region attached with the millimeter wave sensor is in a shielding state. For example, the preset threshold is any value between (-1, 1), although the application is not limited thereto. And under the condition that the preset frequency is that various shelters are sheltered on the outer wall corresponding to the inner wall of the electronic equipment shell region attached to the millimeter wave sensor in advance, millimeter wave signals with different frequencies are input into the microstrip filter, are output after being filtered by the artificial surface plasmon and the defect unit on the microstrip filter, and the transmission coefficient of the output millimeter wave signals with each frequency is calculated. And acquiring the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient, namely the preset frequency of the preset obstruction.
For example, as shown in fig. 5, fig. 5(a) is a schematic diagram of an operating state when an outer wall corresponding to an inner wall of a housing area of an electronic device to which the millimeter wave sensor is attached is in a shielding state, that is, when a shielding object (for example, a human hand) exists on the outer wall, the housing area of the electronic device may refer to a middle frame of the electronic device, and of course, the electronic device may also be provided with an antenna module and other components of the millimeter wave sensor. Fig. 5(b) is a schematic view of an operating state when an outer wall corresponding to an inner wall of a housing region of the electronic device attached with the millimeter wave sensor is in a non-shielding state, that is, when no shielding object exists on the outer wall. Because the shielding object (such as a human hand) is a medium with a large dielectric constant compared with air, when the shielding object exists on the outer wall, a band-stop effect can occur in the obtained transmission characteristic curve, that is, the transmission coefficient of the millimeter wave signal close to a specific frequency is far smaller than that of the millimeter wave signals of other frequencies. And the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient is reduced along with the increase of the dielectric constant of the medium. Therefore, as shown in fig. 6, the horizontal axis of the transmission characteristic curve represents the frequency of the millimeter wave signal and the vertical axis represents the transmission coefficient S21 of the millimeter wave signal, which are obtained through a plurality of experiments, in the hand-held state and the non-hand-held state. Fig. 6(a) is a transmission characteristic curve in the hand-held state, and the frequency average value of the millimeter wave signal corresponding to the lowest transmission coefficient in the hand-held state is close to 28 GHz. Fig. 6(b) is a transmission characteristic curve in the non-grip state, and the frequency average of the millimeter wave signal corresponding to the lowest transmission coefficient in the non-grip state is approximately 29 GHz. And assuming that the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient measured by the millimeter wave sensor at this time is 27.5GHz, and the difference between the 27.5GHz and the 28GHz in the hand-held state is smaller than a preset threshold, the hand-held state can be determined. Therefore, it can be determined whether the millimeter wave signal is in the shielding state (the hand-held state) according to the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient analyzed by the signal processing chip. Here, the human hand is only a kind of shelter, and of course, other shelters exist, for example, when the mobile phone is put into a pocket of clothes, the pocket is a shelter; when the mobile phone is close to the ear, the ear is also a shelter. The above is not exhaustive. For each type of sheltering object, whether the outer wall corresponding to the inner wall of the electronic equipment shell area attached by the millimeter wave sensor is in the sheltering state or not is detected in the same way.
In the embodiment of the application, because the millimeter wave sensor comprises the microstrip filter, the microstrip filter comprises the artificial surface plasmon and the defect unit, and the defect unit mainly plays a role in introducing a band elimination effect into a transmission characteristic curve. Based on the band elimination effect, millimeter wave signals with different frequencies are input into the microstrip filter and output after being filtered by the artificial surface plasmon and the defect unit on the microstrip filter. The signal processing chip calculates the transmission coefficient of the output millimeter wave signal of each frequency, and obtains the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient as the target frequency. And comparing the target frequency with a preset frequency, and when the difference value between the target frequency and the preset frequency is smaller than a preset threshold value, detecting that the outer wall corresponding to the inner wall of the electronic equipment shell region attached with the millimeter wave sensor is in a shielding state.
In one embodiment, the preset frequency is calculated by:
when a preset shielding object exists on the outer wall corresponding to the inner wall of the electronic equipment shell region attached to the millimeter wave sensor, millimeter wave signals with different frequencies are input to the microstrip filter;
millimeter wave signals with different frequencies are output after being filtered by artificial surface plasmons and defect units on the microstrip filter, and the transmission coefficient of the output millimeter wave signals with each frequency is calculated;
and acquiring the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient as the preset frequency of the preset shelter.
Specifically, different shelters are selected in advance to shelter the outer wall corresponding to the inner wall of the electronic equipment shell area, which is attached to the meter wave sensor, and then the frequency average value of the millimeter wave signal corresponding to the lowest transmission coefficient corresponding to the shelters is calculated. The millimeter wave sensor may be connected to the radio frequency generator so that millimeter wave signals of different frequencies transmitted by the radio frequency transmitter may be input to the input of the microstrip filter. Millimeter wave signals with different frequencies are output after being filtered by artificial surface plasmons and defect units on the microstrip filter, the signal processing chip calculates transmission coefficients of the output millimeter wave signals with different frequencies, and the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient at the moment is analyzed and used as the preset frequency of the preset shelter.
The frequencies f of the millimeter wave signals corresponding to the lowest transmission coefficients corresponding to media (shields) having different dielectric constants are different. And the frequency of the millimeter wave signal corresponding to the lowest transmission coefficient is reduced along with the increase of the dielectric constant of the medium.
In the embodiment of the application, different shelters are selected in advance to shelter from the outer wall corresponding to the inner wall of the electronic equipment shell area, which is attached to the meter wave sensor, and then the frequency mean value of the millimeter wave signal corresponding to the lowest transmission coefficient corresponding to the shelters is calculated. Therefore, in the actual detection, whether shielding exists or not can be judged according to the difference value between the target frequency and the preset frequency, and the type of the shielding object is judged. So as to switch the antenna in time or take other measures to improve the communication quality of the electronic equipment.
In one embodiment, comparing the target frequency with a preset frequency, and when a difference between the target frequency and the preset frequency is smaller than a preset threshold, detecting that an outer wall corresponding to an inner wall of an electronic device housing area attached to the millimeter wave sensor is in a shielding state, includes:
comparing the target frequency with the preset frequency of a preset shelter, and detecting that the preset shelter exists on the outer wall corresponding to the inner wall of the electronic equipment shell area attached to the millimeter wave sensor when the difference value between the target frequency and the preset frequency of the preset shelter is smaller than a preset threshold value;
after detecting out that the outer wall that the regional inner wall of electronic equipment shell that millimeter wave sensor laminated corresponds is in the state of sheltering from, include:
sending prompt information according to the type of the preset shielding object to prompt a user to remove the preset shielding object, and communicating through the first antenna module after the preset shielding object is removed.
In the embodiment of the application, the target frequency is compared with the preset frequency of each preset obstruction until the preset frequency with the difference value smaller than the preset threshold value is found, and the preset obstruction corresponding to the preset frequency is correspondingly obtained. Then send out the prompt message according to the type of predetermineeing the shelter to the suggestion user removes predetermineeing the shelter, after removing predetermined shelter, communicates through first antenna module.
In one embodiment, the distance between the millimeter wave sensor and the first antenna module is smaller than a preset distance, including:
the millimeter wave sensor is arranged on the inner surface of the middle frame of the electronic equipment, the first antenna module is arranged on the inner surface of the middle frame of the electronic equipment, and the millimeter wave sensor is connected with the tail end of the first antenna module.

And antenna module generally also sets up at the center internal surface, and the distance between millimeter wave sensor and the first antenna module is less than predetermineeing the distance like this, then detects the outer wall that the inner wall of the electronic equipment center that millimeter wave sensor laminated corresponds through millimeter wave sensor and is in sheltering from the state, then first antenna module will also be in sheltering from the state. In order to ensure the communication quality of the electronic device, the second antenna module can be switched to perform communication.
In the embodiment of the application, the millimeter wave sensor and the first antenna module are both arranged on the inner wall of the middle frame of the electronic equipment, and the millimeter wave sensor is connected with the tail end of the first antenna module. Like this when detecting the outer wall that the inner wall of the electronic equipment center that the millimeter wave sensor was laminated corresponds through the millimeter wave sensor and be in the state of sheltering from, then will accurately detect that first antenna module will also be in the state of sheltering from.

The dielectric constant of each preset shielding object is different, and the length of the first metal sheet and the length of the second metal sheet influence the transmission coefficient of the output millimeter wave signal of each frequency. Therefore, when the length of the first metal sheet, the length of the second metal sheet and the preset shielding object are fixed, the calculated target frequency is in one-to-one correspondence with the length of the first metal sheet, the length of the second metal sheet and the preset shielding object.
