Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, fig. 1 is a schematic flowchart of an antenna tuning method provided in an embodiment of the present application, where the antenna tuning method is applied to an electronic terminal, and as shown in fig. 2, the electronic terminal 20 includes a radiation antenna 21 and a plurality of detection antennas located around the radiation antenna 21, the radiation antenna 21 is generally disposed at the bottom of the electronic terminal 20, and the detection antennas are used for detecting a blocked condition of the radiation antenna 21. The plurality of detecting antennas are located near the radiating antenna 21 and cover the left, right and upper positions of the radiating antenna 21. Each detection antenna may be adjacent to, semi-surrounding, or partially surrounding the radiation antenna 21, and the shape of each detection antenna may be rectangular, polygonal, curved, or the like, and is not particularly limited herein. The closer the distance between the detecting antenna and the radiating antenna 21 is, the better the detecting effect is, but the too close distance affects the radiating effect of the radiating antenna 21, so the distance between the detecting antenna and the radiating antenna 21 can be set to be 4-5 mm. The more the number of the detection antennas, the better the detection effect, but considering the cost and the space size, it is preferable to provide three detection antennas, i.e., the first detection antenna 22, the second detection antenna 23, and the third detection antenna 24. The first detection antenna 22 is located on the left side of the radiation antenna 21, the second detection antenna 23 is located above the radiation antenna 21, and the third detection antenna 24 is located on the right side of the radiation antenna 21.
As shown in fig. 1, the antenna tuning method may include steps 101 to 104:
101. and determining the current posture of the electronic terminal.
In the embodiment of the application, the gesture of the electronic terminal may include a landscape screen state or a portrait screen state, for example, when a user calls or sends information by using the electronic terminal, the gesture of the electronic terminal is generally the portrait screen state; when a user plays a game and watches a video by adopting the electronic terminal, the posture of the electronic terminal is generally a landscape screen posture. And determining the current posture of the electronic terminal, namely determining whether the electronic terminal is in a horizontal screen state or a vertical screen state currently. The posture of the electronic terminal can be detected by a gravity sensor built in the electronic terminal.
102. And determining a tuning trigger condition corresponding to the gesture.
In the embodiment of the application, when the electronic terminal is in different postures, the positions of the palms and the fingers of the hands covering the electronic terminal are different, so that the areas of the hands shielding the detection antennas are different. The detection antenna is located at the periphery of the radiation antenna, and the shielded area condition of the detection antenna can reflect the shielded area condition of the radiation antenna, namely when the electronic terminal is in different postures, the shielded areas of the radiation antenna are different, and the condition for triggering the tuning of the radiation antenna and the parameter required for tuning of the radiation antenna are different.
Presetting tuning trigger conditions when the electronic terminal is in different postures, for example, if the landscape screen state corresponds to a first tuning trigger condition, and the portrait screen state corresponds to a second tuning trigger condition, and the first tuning trigger condition is different from the second tuning trigger condition, determining the first tuning trigger condition when the posture of the electronic terminal is in the landscape screen state; and when the posture of the electronic terminal is in a vertical screen state, determining a second tuning trigger condition.
103. And detecting the capacitance value formed by each detection antenna in real time.
In this embodiment of the application, the tuning trigger conditions corresponding to different gestures of the electronic terminal may be conditions related to a capacitance value formed by the detection antenna, or conditions related to a shielded area of the detection antenna. And comparing the detected capacitance value or the shielded area with a tuning trigger condition corresponding to the current posture of the electronic terminal by detecting the capacitance value or the shielded area formed by each detection antenna so as to judge whether to trigger tuning of the radiation antenna. The shielded area of the detection antenna can be determined by the capacitance value formed by the detection antenna, and the larger the shielded area of the detection antenna is, the larger the capacitance value formed by the detection antenna is, so that the corresponding relation between the capacitance value and the shielded area can be preset, and the shielded area of the detection antenna can be determined according to the size of the detected capacitance value.
When a human hand holds the electronic terminal, the radiation antenna is shielded, the detection antenna is shielded, a capacitor is formed between the detection antenna and the human hand, the detection antenna is equivalent to one polar plate of the capacitor, and the human hand is equivalent to the other polar plate of the capacitor. A capacitance detection chip is arranged in the electronic terminal, each detection antenna is connected with the capacitance detection chip, and the capacitance detection chip can detect the capacitance value of a capacitor formed between a human hand and the detection antenna in real time. When the electronic terminal is not held by a hand of a person, no capacitor is formed at the detection antenna, or the capacitance value of the formed capacitor is infinitesimal, and the shielded area of the detection antenna approaches to 0.
Because when electronic terminal placed on wooden or metal material's object, the detection antenna of radiation antenna top is sheltered from, and the capacitance value of the certain size of capacitance detection chip can detect top detection antenna, but this kind of condition is less to radiation antenna's performance influence, need not to tune radiation antenna. Therefore, in order to avoid false triggering of tuning in this case, the capacitance values formed by all the detection antennas can be combined to determine whether to trigger tuning of the radiating antenna.
In one embodiment, the tuning trigger condition comprises a capacitance threshold. The method further comprises the following steps:
detecting whether the capacitance value formed by each detection antenna is larger than the capacitance threshold value; and if so, judging that the capacitance values formed by the plurality of detection antennas meet the tuning trigger condition, otherwise, judging that the shielded areas of the plurality of detection antennas do not meet the tuning trigger condition.
It should be noted that the capacitance thresholds in the tuning trigger conditions corresponding to different postures are different, for example, the first tuning trigger condition corresponding to the landscape screen state includes a first capacitance threshold, the second tuning trigger condition corresponding to the portrait screen state includes a second capacitance threshold, and the first capacitance threshold is different from the second capacitance threshold.
Because the positions of the multiple detection antennas are different, the shielded areas are different, and the requirements of capacitance values are also different, the capacitance threshold value in the tuning triggering condition can comprise multiple capacitance threshold value parameters, so that the multiple capacitance threshold value parameters correspond to the multiple detection antennas one to one. The plurality of capacitance threshold parameters may be the same or different. Respectively detecting whether the capacitance value formed by each detection antenna is larger than the corresponding capacitance threshold parameter, if so, indicating that the electronic terminal is held by hands, and determining that the capacitance values formed by the plurality of detection antennas meet the tuning trigger condition; if the capacitance value formed by any detection antenna is smaller than the corresponding capacitance threshold value parameter, the electronic terminal is not held by a human hand, and the capacitance values formed by the multiple detection antennas are determined not to meet the tuning trigger condition.
In another embodiment, the tuning trigger condition comprises a tolerance threshold. The method further comprises the following steps:
forming any two detection antennas into a group of antennas, and detecting whether the difference value of the capacitance values formed by the two detection antennas in each group of antennas is larger than the capacitance difference threshold value; and if the tuning trigger condition is met, judging that the capacitance values formed by the plurality of detection antennas meet the tuning trigger condition, and if the tuning trigger condition is not met, judging that the capacitance values formed by the plurality of detection antennas do not meet the tuning trigger condition.
It should be noted that the capacitance difference thresholds of the tuning trigger conditions corresponding to different postures are different, for example, the first tuning trigger condition corresponding to the landscape screen state includes a first capacitance difference threshold, the second tuning trigger condition corresponding to the portrait screen state includes a second capacitance difference threshold, and the first capacitance difference threshold is different from the second capacitance difference threshold.
Because the hand-held electronic terminal has certain regularity, the shielded areas of the detection antennas at different positions have certain regularity, and the capacitance difference values among different detection antennas are different, the capacitance difference threshold value in the tuning triggering condition can comprise a plurality of capacitance difference threshold value parameters, so that the plurality of capacitance difference threshold value parameters correspond to the plurality of groups of antennas one to one. The plurality of capacitance difference threshold parameters may be the same or different. Respectively detecting whether the difference value of capacitance values formed by two detection antennas in each group of antennas is larger than a capacitance difference threshold parameter corresponding to the group of antennas, if so, indicating that the electronic terminal is held by hands, and determining that the capacitance values formed by the multiple detection antennas meet the tuning trigger condition; and if the difference value of the capacitance values formed by any group of antennas is smaller than the capacitance difference threshold parameter corresponding to the group of antennas, the electronic terminal is not held by hands, and the capacitance values formed by the multiple detection antennas are determined not to meet the tuning trigger condition.
In yet another embodiment, the tuning trigger condition includes a total capacitance threshold. The method further comprises the following steps:
detecting whether the sum of the capacitance values formed by the plurality of detection antennas is greater than the total capacitance threshold value; and if the tuning trigger condition is met, judging that the capacitance values formed by the plurality of detection antennas meet the tuning trigger condition, and if the tuning trigger condition is not met, judging that the capacitance values formed by the plurality of detection antennas do not meet the tuning trigger condition.
It should be noted that the total capacitance thresholds in the tuning trigger conditions corresponding to different postures are different, for example, the first tuning trigger condition corresponding to the landscape screen state includes a first total capacitance threshold, the second tuning trigger condition corresponding to the portrait screen state includes a second total capacitance threshold, and the first total capacitance threshold is different from the second total capacitance threshold.
During detection, firstly calculating the sum of capacitance values formed by the multiple detection antennas, and then detecting whether the calculated sum of the capacitance values is larger than a total capacitance threshold value, if so, indicating that the electronic terminal is held by a hand, and determining that the capacitance values formed by the multiple detection antennas meet the tuning trigger condition; if not, the electronic terminal is not held by hands, and the capacitance formed by the detection antennas is determined not to meet the tuning trigger condition.
104. And tuning the radiation antenna when the capacitance values formed by the plurality of detection antennas meet the tuning trigger condition.
In the embodiment of the application, when the capacitance formed by the plurality of detection antennas does not meet the tuning trigger condition, tuning operation is not triggered, namely, the radiation antenna is not tuned, so that the antenna resonance in a free space state is just corresponding to the required frequency range, and the performance of the radiation antenna is ensured.
When the capacitance values formed by the plurality of detection antennas meet the tuning trigger condition, the tuning operation is triggered, namely, the radiation antenna is tuned. The tuning device is arranged at the position of the radiating antenna, and when the radiating antenna is tuned, different control instructions are transmitted to the tuning device according to capacitance values formed by the plurality of detection antennas, so that the tuning device can realize different capacitance values, the radiating antenna can be straightened through the tuning device, smaller return loss is ensured, and the efficiency of the radiating antenna is improved. For example, the current communication frequency band of the electronic terminal operates at 800MHz, the resonant frequency of the electronic terminal in a free space state is 800MHz, when the electronic terminal is held by a hand, the resonant frequency of the radiation antenna shifts to 700MHz due to the influence of the hand, and the performance of the 800MHz antenna is poor, so that the resonant frequency of the radiation antenna is pulled back to 800MHz by adjusting the capacitance value of the tuning device.
Specifically, the tuning the radiation antenna includes:
determining a target capacitance range to which capacitance values formed by the plurality of detection antennas belong from a plurality of preset capacitance ranges; determining a tuning parameter corresponding to the target capacitance range; and tuning the radiation antenna according to the tuning parameters.
It should be noted that, because the electronic terminal is held by a human hand in different postures, the human hand can hold the electronic terminal in different ways, such as a left hand, a right hand or both hands. Different hand-held modes lead to different positions and areas for shielding the detection antennas, and further lead to different capacitance values formed by each detection antenna and different tuning required by the radiation antennas.
The capacitance ranges are preset, for example, the range of capacitance values which can be generated by each hand-holding manner is preset, tuning parameters corresponding to each hand-holding manner are set, and a one-to-one correspondence relationship between the capacitance ranges and the tuning parameters is established.
Furthermore, a target capacitance range to which capacitance values formed by the plurality of detection antennas belong is detected, for example, a preset capacitance range is a capacitance range corresponding to the whole of the plurality of detection antennas, a target capacitance range to which the sum of capacitance values formed by the plurality of detection antennas belongs is detected to determine a tuning parameter corresponding to the target capacitance range, and the capacitance value of the tuning device is adjusted according to the tuning parameter, thereby tuning the radiation antenna.
Therefore, the antenna tuning method provided by the application can determine the current attitude of the electronic terminal, and further determine the tuning trigger condition corresponding to the attitude, so as to detect the capacitance value formed by each detection antenna in real time, and tune the radiation antenna when the capacitance values formed by a plurality of detection antennas meet the tuning trigger condition, thereby ensuring that the radiation antenna keeps the optimal efficiency or the optimal performance state in different use scenes.
