Detailed Description
Fig. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. Referring to fig. 1, in the present embodiment, the electronic device 10 is, for example, a notebook computer, a tablet computer, a mobile phone or other devices. The electronic device of the present embodiment includes a housing 11, an antenna control assembly 12 disposed in the housing 11, and a plurality of antennas 13, 14, 15, 16 disposed in the housing 11. The antennas 13, 14, 15, 16 are electrically connected to the antenna control assembly 12. In the present embodiment, these antennas 13, 14, 15, 16 are located inside the housing 11 and can be regarded as internal antennas.
In addition, the number of the antennas 13, 14, 15, 16 is exemplified by 4, but not limited thereto, and in other embodiments, the number of the antennas may be 6, 8, or more. In the present embodiment, the four antennas 13, 14, 15, 16 are respectively disposed at four corners of the housing 11 to receive signals in different directions, so as to enhance the reception and transmission of the antenna signals. Of course, the positions where the antennas 13, 14, 15, 16 are arranged are not limited thereto.
Since a portion of the housing 11 of the electronic device 10 may be metal, the antennas 13, 14, 15, 16 may be shielded by metal and may not fully exert their original efficiency, in this embodiment, the antenna control unit 12 may detect the receiving and transmitting states of the antennas 13, 14, 15, 16, respectively, and adjust the optimal antenna settings accordingly.
The electronic device 10 may detect traffic, noise conditions, signal strength (RSSI), and signal-to-noise ratio (SNR) of the antennas 13, 14, 15, 16 through the antenna control component 12. The electronic apparatus 10 controls the antennas 13, 14, 15, 16 in accordance with the CPU state (use rate or efficiency), memory state (use rate or efficiency), states of the internal devices such as temperature, voltage, current, power consumption, and frequency, memory state, and Power supply (Power) state.
In the present embodiment, the antennas 13, 14, 15, 16 can provide multi-band effect and have good antenna efficiency by the following control method. In the following, four antennas are exemplified, but the number of antennas is not limited thereto.
Fig. 2 is a flow chart of a control method of a multi-antenna module according to an embodiment of the invention. Referring to fig. 2, the control method 100 of the multi-antenna module of the present embodiment includes the following steps.
First, in step 110, a plurality of antennas are provided, and the antennas excite at least a signal in a first frequency band and a signal in a second frequency band. In this embodiment, the first frequency Band and the second frequency Band may be different frequency bands in the 4G signal, such as any two of FDD-LTE Band 1 (2100 MHz), FDD-LTE Band3 (1800 MHz), FDD-LTE Band 7 (2600 MHz), FDD-LTE Band 8 (900 MHz), FDD-LTE Band 28 (700 MHz) and TD-LTE Band 38 (2600 MHz). Of course, the first frequency band and the second frequency band are not limited thereto. In other embodiments, the first frequency band and the second frequency band may be different frequency bands in WIFI, BT, and 5G signals.
Then, in step 120, the performance of the antennas in the first frequency band and the second frequency band is detected, and the antennas are divided into a first group and a second group outside the first group, wherein the performance in the first frequency band is better than the performance in the second frequency band, and the number of antennas in each of the first group and the second group is at least two. The performance of the antenna in the frequency band refers to the power intensity of the antenna for signal transmission in the frequency band.
For example, in the present embodiment, two antennas perform better in the first frequency band than in the second frequency band, and the other two antennas perform better in the second frequency band than in the first frequency band, the two antennas with better performance in the first frequency band are classified as a first group, and the two antennas with better performance in the second frequency band are classified as a second group. Of course, in an embodiment, two of the four antennas that perform better in the first frequency band than in the second frequency band may be selected as the first group, and the rest may be divided into the second group.
Then, in step 130, the first group is instructed to deactivate the signal of the first frequency band, and the second group is instructed to deactivate the signal of the second frequency band. Since the first group performs well in the first frequency band, signals indicative of the first group de-energizing the first frequency band ensure good performance of the antenna in the first frequency band. Furthermore, since the second group contributes less to the first frequency band, there is a limited increase in antenna efficiency compared to using the second group to excite the first frequency band. In particular, the second group may have a better performance in the second frequency band, and the control method 100 of the multi-antenna module uses the second group to excite the second frequency band, so that the antenna can achieve the effect of using multiple frequency bands simultaneously, and can have good antenna efficiency in the first frequency band and the second frequency band. The antenna efficiency referred to in the present invention refers to the power of signal transmission (i.e. the power of data uploading), and its unit may be dBm, which represents the absolute value of power, or a ratio (%) based on 1mW of power, where the larger the value or ratio, the higher the power of signal transmission, i.e. the better the antenna efficiency.
In addition, in an embodiment, the control method of the multi-antenna module optionally further includes step 140, operating both of the antennas with optimal efficiency at the optimal setting, and operating a plurality of remaining antennas of the antennas with a plurality of ratios increasing in equal difference from the initial ratio with 30% -50% of the optimal setting as an initial ratio, and measuring a plurality of antenna efficiencies of the remaining antennas when operating at the ratios, so as to select an optimal ratio among the ratios.
Specifically, due to the difference in antenna positions, the antennas in different directions may have different antenna efficiencies, and for optimization, in the control method of the multi-antenna module of the present embodiment, two antennas with the best antenna efficiency are selected first, and the two antennas are operated with an optimal setting (for example, 100%). The present invention refers to an optimization setting, in which the multi-antenna module detects and determines the antenna efficiency of a plurality of frequency bands (for example, 4G, WIFI, BT or 5G) provided by a telecommunications carrier, and sets the antenna in the frequency band with the best antenna efficiency.
In addition, other antennas may be operated and the antenna efficiency of the antennas may be measured, first with an optimally set 30% to 50% as an initial ratio, and with 1% to 10% as an interval step by step. For example, the other antennas may be first stepped up at an initial rate of 30% for the optimal setting and at 5% intervals, and tested for antenna efficiency at 30%, 35%, 40%, 45%, 50% for the optimal setting.
Then, the antenna efficiencies corresponding to the ratios from small to large are compared, and in the antenna efficiencies, when the amplification of one of the antenna efficiencies is smaller than a preset value (for example, 0.5dBm or a preset ratio (for example, 5%) compared with the former, the amplification representing the antenna efficiency is limited, so that the ratio corresponding to the antenna efficiency is used as an optimization ratio, and energy can be saved.
Finally, as in step 150, the remaining antennas (other than the two antennas with the best antenna efficiency) are operated at this optimized ratio.
In another embodiment, the control method of the multi-antenna module optionally further includes a step 142 of operating both of the antennas with optimal antenna efficiency at a preset ratio, wherein the preset ratio is 70% -100%, and operating a plurality of remaining antennas of the antennas at a plurality of ratios decreasing from the preset ratio with equal difference, and measuring a plurality of antenna efficiencies of the remaining antennas when operating at the ratios to select an optimal ratio among the ratios; and operating the remaining antennas at an optimized ratio.
Specifically, in the control method of the multi-antenna module of the present embodiment, two antennas with optimal antenna efficiency are selected first, and the two antennas are operated at a predetermined ratio (e.g., 80%).
Further, it is possible to operate other antennas starting from a preset ratio (for example, 70% to 100%) with, for example, 1% to 10% as an interval step-down, and measure the multiple antenna efficiency when operating at these ratios. For example, the other antennas may be first stepped down at 80% as a predetermined ratio and 5% as intervals, and the antennas are tested for antenna efficiency under 80%, 75%, 70%, 65%, 60%, etc.
Then, comparing the antenna efficiencies corresponding to the ratios from large to small, in the antenna efficiencies, when the decreasing amplitude of one of the antenna efficiencies compared with the former antenna efficiency is larger than a preset value (for example, 0.5 dBm) or a preset ratio (for example, 5%), the ratio corresponding to the antenna efficiency is used as an optimized ratio, so that energy can be saved.
Finally, as in step 150, the remaining antennas (other than the two antennas with the best antenna efficiency) are operated at this optimized ratio.
In yet another embodiment, the control method of the multi-antenna module optionally further includes step 144 of operating the first group with the optimal setting, and operating the second group with a plurality of rates in equal increments starting from the initial rate with 30% -50% of the optimal setting as an initial rate, and measuring a plurality of antenna efficiencies of the second group when operating at the rates to select an optimal rate among the rates. Finally, the second group is run at this optimized ratio, as in step 152.
In this embodiment, the first frequency band is used as the main frequency band, and the antennas for exciting the first frequency band are all operated at the optimal setting. The second frequency band is used as a secondary frequency band, and the running setting is adjusted on the premise of saving energy.
In yet another embodiment, the control method of the multi-antenna module optionally further includes a step 146 of operating the first group at a predetermined ratio and operating the second group at a plurality of ratios decreasing from the predetermined ratio with equal difference, and measuring a plurality of antenna efficiencies of the second group when operating at the ratios to select an optimized ratio among the ratios, wherein the predetermined ratio is 70% -100%. Finally, the second group is run at this optimized ratio, as in step 152. In this embodiment, the first frequency band is used as the main frequency band, and the antennas for exciting the first frequency band are operated at a higher predetermined ratio. The second frequency band is used as a secondary frequency band, and the running setting is adjusted on the premise of saving energy.
Fig. 3 is a schematic diagram of an electronic device according to another embodiment of the invention. Referring to fig. 3, the electronic device 10a of the present embodiment includes four antennas 13, 14, 15, 16 located inside the housing 11 and two antennas 15a, 16a outside the housing 11. The antennas 13, 14, 15, 16, 15a, 16a are electrically connected to the antenna control assembly 12. In the present embodiment, the four antennas 13, 14, 15, 16 located within the housing 11 may be regarded as internal antennas. The two antennas 15a, 16a located outside the housing 11 may be regarded as external antennas. Of course, the number and configuration of the antennas are not limited thereto. In other embodiments, the electronic device 10a may also include eight or other numbers of antennas.
For the multi-antenna module with the internal antenna and the external antenna, the electronic device 10a can detect the signal flow, the signal intensity, the noise intensity and the temperature, and then match with the identification system to determine whether a person or an object is near to use, so as to automatically adjust the receiving and transmitting of the antenna intensity signal. The system can adjust the signal strength, idle or operation and 3G/4G/5G switching functions for each antenna 13, 14, 15, 16, 15a, 16a, respectively, and can detect the information such as flow, noise status, signal strength RSSI, and signal-to-noise ratio (SNR). The control method 100a of the multi-antenna module is provided below.
Fig. 4 is a flow chart of a control method of a multi-antenna module according to another embodiment of the invention. Referring to fig. 4, in step 110a, a plurality of antennas are provided, which at least excite signals in a first frequency band and signals in a second frequency band, and include a plurality of internal antennas and a plurality of external antennas. In this embodiment, the first frequency Band and the second frequency Band may be different frequency bands in the 4G signal, such as any two of FDD-LTE Band 1 (2100 MHz), FDD-LTE Band3 (1800 MHz), FDD-LTEBand 7 (2600 MHz), FDD-LTE Band 8 (900 MHz), FDD-LTE Band 28 (700 MHz) and TD-LTE Band 38 (2600 MHz). Of course, the first frequency band and the second frequency band are not limited thereto. In other embodiments, the first frequency band and the second frequency band may be different frequency bands in WIFI, BT, and 5G signals.
Then, in step 120, the performance of the antennas in the first frequency band and the second frequency band is detected, and the antennas are divided into a first group and a second group outside the first group, wherein the performance in the first frequency band is better than the performance in the second frequency band, and the number of antennas in each of the first group and the second group is at least two. Then, in step 130, the first group is instructed to deactivate the signal of the first frequency band, and the second group is instructed to deactivate the signal of the second frequency band.
In this embodiment, the control method of the multi-antenna module further includes step 170 of determining whether a person or object is close to the housing. In the step of determining whether a person or object is approaching the housing, the antenna control assembly 12 in the housing 11 further includes a detection module (not shown), for example, including at least one of an optical detection module, a sound receiving module, a distance detection module and a peripheral module to detect whether a person or object is approaching the housing.
In detail, the optical detection module includes a face recognition system or an infrared module, and can optically detect whether a person or object is approaching. The sound receiving module comprises a microphone and can detect whether sound is received. The distance detection module comprises an ultrasonic detection module and can detect whether the distance between surrounding objects or people is changed. The peripheral module is electrically connected to the electronic device and comprises a keyboard or a mouse, and the system can judge whether a person approaches by judging whether an input signal exists.
In step 180, the antenna control unit 12 in the housing 11 further includes a detection chip (not shown), such as an operation element including an SOC or an MCU, and when the detection module detects that a person or object is approaching, the detection chip sends an approaching signal to the detection chip, and the detection chip determines and controls the operation of the antennas respectively to optimize the settings for operating the external antennas and to lower the settings for operating the internal antennas. The internal antennas operate at a lower setting (i.e., lower signal transmit power) to reduce electromagnetic wave effects in close proximity to the human body, and the external antennas operate at an optimized setting that can be used to maintain stability and transmission speed at the original high rate.
In one embodiment, the step of operating the internal antennas at a lower setting includes step 182 of operating the internal antennas at a plurality of rates in equal increments starting from the initial rate with an optimal setting of 30% -50% as an initial rate, and measuring the antenna efficiencies of the internal antennas when operating at the rates to select an optimal rate among the rates. Finally, the internal antennas are operated at an optimized ratio, as in step 186.
In another embodiment, the step of operating the internal antennas at a lower setting includes step 184 of operating the internal antennas at a plurality of rates decreasing equally from a predetermined rate, and measuring the antenna efficiencies of the internal antennas when operating at the rates to select an optimal rate among the rates, wherein the predetermined rate is 70% -100%. Finally, the internal antennas are operated at an optimized ratio, as in step 186.
Of course, the manner of operating the internal antennas is not limited to the above, and in other embodiments, in the step of operating the internal antennas at a lower setting, the internal antennas may be operated at an optimum setting of 40% -70% (e.g., 50%).
In addition, in an embodiment, the control method of the multi-antenna module may also be step 170 and step 180 following step 110 a. Then, step 120 and step 130 are performed. In an embodiment, the control method of the multi-antenna module may be performed as shown in fig. 4, and after step 180, the system may determine the performances of the antennas in the first frequency band and the second frequency band again, and re-divide the new first group and the new second group.
In summary, the method for controlling a multi-antenna module according to the present invention divides the antennas into a first group and a second group outside the first group, which have better performance in the first frequency band than the second frequency band, by detecting the performance of the antennas in the first frequency band and the second frequency band. Thereafter, the first group is instructed to deactivate signals of the first frequency band and the second group is instructed to deactivate signals of the second frequency band. Therefore, the control method of the multi-antenna module can ensure that the antenna has good performance in the first frequency band. In addition, since the second group has less contribution to the first frequency band, the control method of the multi-antenna module of the present invention uses the second group to excite the second frequency band, so as to achieve the multi-frequency band effect, compared with the method of using the second group to excite the first frequency band to have limited increase of the antenna efficiency.
