Abstract

The present disclosure relates to an antenna module and an electronic device. The antenna module includes a feed end, a first antenna radiator, a control switch and a first frequency tuning circuit. The first antenna radiator is electrically connected to the feed end. One end of the first frequency tuning circuit is electrically connected to a ground point, and the other end is electrically connected to the first antenna radiator through the control switch. When the antenna module is in a first mode, the control switch is switched to an open position, and the first frequency tuning circuit and the first antenna radiator are disconnected. When the antenna module is in a second mode, the control switch is switched to a closed position, and the first frequency tuning circuit and the first antenna radiator are electrically connected. In the above arrangement, when the antenna module is in the first mode, the position of the first antenna radiator away from the feed end is disconnected from the ground point, so that the first antenna radiator only has one current strong point in the first mode, thereby reducing the performance imbalance of the left and right head models.

[0078] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0079] like Figure 1 and Figure 2 As shown, this application discloses an electronic device 600, which includes an antenna module 100 for receiving and transmitting signals. In this embodiment, the electronic device 600 is a mobile phone. A mobile phone typically has one or two antenna modules 100. When a mobile phone has two antenna modules 100, one antenna module 100 is located at the top of the phone, and the other antenna module 100 is located at the bottom of the phone. Of course, in other embodiments, the electronic device 600 can also be other devices with antenna modules 100 and communication functions, such as computers, tablets, e-readers, watches, headphones, medical devices, fitness equipment, personal digital assistants, etc.

[0080] The electronic device 600 also includes a device frame 200, and the antenna module 100 is disposed inside the device frame 200. The device frame 200 can provide support and protection for the antenna module 100 and other electronic components.

[0081] As shown in the figure, in this embodiment, the antenna module 100 includes a feed terminal 110, a first antenna radiator 120, a control switch 130, and a first frequency modulation circuit 140. The first frequency modulation circuit 140 can adjust the equivalent capacitance or inductance value of the antenna module 100.

[0082] The first antenna radiator 120 is electrically connected to the feed terminal 110. One end of the first frequency modulation circuit 140 is electrically connected to a ground point, and the other end is electrically connected to the first antenna radiator 120 via a control switch 130. The control switch 130 can be switched between an open position 131 and a closed position 132. (Reference) Figure 2 As shown, when the control switch 130 is switched to the off position 131, the first frequency modulation circuit 140 and the first antenna radiator 120 are disconnected. (Reference) Figure 1 As shown, when the control switch 130 is switched to the closed position 132, the control switch 130 can act as a conductive wire, with its two ends electrically connected to the first frequency modulation circuit 140 and the first antenna radiator 120, so that the first frequency modulation circuit 140 and the first antenna radiator 120 are electrically connected.

[0083] Antenna module 100 can switch between a first mode and a second mode.

[0084] like Figure 2 As shown, when the antenna module 100 is in the first mode 101, the frequency band covered by the antenna module 100 is the first frequency band. Figure 1 As shown, when the antenna module 100 is in the second mode, the frequency band covered by the antenna module 100 is the second frequency band. The first frequency band is smaller than the second frequency band. In this embodiment, when the antenna module 100 is in the first mode 101, the frequency band covered by the antenna module 100 is called the low frequency band; therefore, the first mode 101 is also called the low frequency mode. Its covered frequency band is approximately 700MHz to 960MHz; in other words, the antenna module 100 operates in the 700MHz to 960MHz range. Meanwhile, in this embodiment, the second mode also includes a mid-frequency mode 102 and a high-frequency mode 103 (see reference). Figure 9 and Figure 10 (As shown). When antenna module 100 is in the intermediate frequency (IF) mode 102 of the second mode, the frequency band covered by antenna module 100 is called the IF band, which is approximately 1710MHz to 2170MHz. In other words, antenna module 100 operates in the range of 1710MHz to 2170MHz. Correspondingly, the first frequency band is 1710MHz to 2170MHz. When antenna module 100 is in the high frequency (HF) mode 103 of the second mode, the frequency band covered by antenna module 100 is called the IF band, which is approximately 2300MHz to 2690MHz. In other words, antenna module 100 operates in the range of 2300MHz to 2690MHz. Of course, in other embodiments, the second mode may only be IF mode 102 or only HF mode 103. Correspondingly, the second frequency band is 2300MHz to 2690MHz.

[0085] like Figure 3As shown, in one design, the first antenna radiator 120 is provided with a first electrical connection point A and a second electrical connection point B. The first electrical connection point A is electrically connected to the feed terminal 110. Regardless of whether the antenna module 100 is in the first mode 101 or the second mode, the second electrical connection point B is electrically connected to the grounding point through a capacitor or an inductor to achieve grounding. In the above design, when the first antenna radiator 120 is in the first mode 101 (low-frequency mode), the first antenna radiator 120 mainly participates in radiation. At this time, the current on the first antenna radiator 120 is as follows: Figure 4 As shown. Since the low-frequency current null point of the antenna is located at the end of the low-frequency stub of the antenna, the low-frequency current null point of the terminal's antenna will be located on the left side of the antenna. Furthermore, strong current points are generated at both the first electrical connection point A and the second electrical connection point B. When the user communicates using their right hand to hold the terminal, the right hand is closer to the left side of the antenna. This hand position causes the low frequency to be lower and absorbs antenna efficiency, thus reducing communication performance. Simultaneously, it severely affects the strong current points at the first electrical connection point A and the second electrical connection point B. When the user communicates using their left hand to hold the terminal, the left hand is farther from the left side of the antenna, resulting in less impact on communication performance and less impact on the strong current points at the first electrical connection point A and the second electrical connection point B. Therefore, the low-frequency performance of the right-hand hand position is worse than that of the left-hand hand position, with a difference of approximately 3dB.

[0086] Based on this, the present application discloses an antenna to solve the problem that the performance imbalance of the antenna in the left and right head and hand modes at low frequencies affects the communication quality of the terminal in the head and hand mode state.

[0087] like Figure 2 As shown, in this embodiment, the first electrical connection point A on the first antenna radiator 120 is electrically connected to the feed terminal 110, and the second electrical connection point B on the first antenna radiator 120 is electrically connected to the control switch 130.

[0088] When antenna module 100 is in the first mode 101, the position of the first antenna radiator 120 furthest from the feed terminal 110 is disconnected from the ground point. In other words, when control switch 130 is switched to the off position 131, the second electrical connection point B is disconnected from the electrical connection between the first frequency modulation circuit 140 and the ground point. At this time, the current on the first antenna radiator 120 is as follows: Figure 5As shown. With the above settings, when the antenna module 100 is in the first mode 101, the first antenna radiator 120 has only one strong current point in the first mode 101, that is, the strong current point exists at the first electrical connection point A. Extensive experiments have shown that when the antenna module 100 is in the first mode 101 (low-frequency mode), the first antenna radiator 120 has only one strong current point. Regardless of whether the user uses their right or left hand to hold the terminal for communication, the difference in the impact on the strong current point between the two scenarios is small. In other words, when the user holds the electronic device 600 with their left or right hand, the impact of left- or right-hand holding on the strong current point can be reduced, and the difference in the impact of left- or right-hand holding on the strong current point can be reduced, thereby reducing the performance imbalance between the left and right head modes, and thus ensuring the communication quality of the terminal in head-and-hand mode.

[0089] like Figure 1 When the antenna module 100 is in the second mode, the control switch 130 switches to the closed position 132, and the first frequency modulation circuit 140 and the first antenna radiator 120 are electrically connected. At this time, the first frequency modulation circuit 140 can adjust its capacitance or inductance value to adjust the mid-to-high frequency resonant frequency of the antenna module 100, thereby achieving full-band coverage.

[0090] like Figure 1 and Figure 2 As shown, in this embodiment, the antenna module 100 includes a second frequency modulation circuit 150, with its two ends electrically connected to the feed terminal 110 and the first antenna radiator 120, respectively. The second frequency modulation circuit 150 includes a first capacitor C1, with its two ends electrically connected to a first electrical connection point A of the feed terminal 110 and the first antenna radiator 120, respectively. In this embodiment, the first capacitor C1 is a variable capacitor. Regardless of whether the antenna module 100 is in the first mode 101 or the second mode, the resonant frequency of the antenna module 100 can be adjusted by adjusting the capacitance value of the first capacitor C1. For example, by reducing the capacitance value of the equivalent capacitor, the resonant frequency of the antenna module 100 can be increased, thereby achieving full-band coverage.

[0091] Furthermore, the second frequency modulation circuit 150 also includes a second capacitor C2. One end of the second capacitor C2 is electrically connected to a ground point. The other end of the second capacitor C2 is electrically connected between the feed terminal 110 and the first capacitor C1 (see reference). Figure 1 and Figure 2 (As shown). Alternatively, the other end of the second capacitor C2 is electrically connected between the first capacitor C1 and the first antenna radiator 120 (see reference). Figure 6(As shown). In this embodiment, the second capacitor C2 is a variable capacitor. By adjusting the capacitance value of the second capacitor C2, and by using the first capacitor C1 in conjunction with it, the resonant frequency of the antenna module 100 can be adjusted by adjusting the equivalent capacitance value of the antenna module 100. For example, by reducing the capacitance value of the equivalent capacitor, the resonant frequency of the antenna module 100 can be increased, thereby achieving full-band coverage.

[0092] In this embodiment, regardless of whether the antenna module 100 is in the first mode 101 or the second mode, the resonant frequency of the antenna module 100 can be adjusted by adjusting the first capacitor C1 and the second capacitor C2, thereby achieving full-band coverage. Simultaneously, adjusting the second capacitor C2 can also change the resonant position, thereby adjusting the impedance, better matching the transmitter, effectively reducing return loss, and improving radiation efficiency.

[0093] In this embodiment, as Figure 7 As shown, the device frame 200 also includes a metal grounding frame 160 and a control circuit board 170. The grounding frame 160 is grounded, and one end of the first frequency modulation circuit 140, away from the control switch 130, can be electrically connected to the grounding frame 160, thus connecting one end of the first frequency modulation circuit 140 to the grounding point. One end of the second capacitor C2 can be electrically connected to the grounding frame 160, thus connecting one end of the second capacitor C2 to the grounding point. The first capacitor C1 and the second capacitor C2 in the second frequency modulation circuit 150, the control switch 130, and the first frequency modulation circuit 140 can all be fixedly connected to the control circuit board 170. The control circuit board 170 also has a control chip, which can be electrically connected to the power supply terminal 110 and the control switch 130, and can control them, etc.

[0094] Combination Figure 1 , Figure 2 and Figure 7As shown, the first frequency modulation circuit 140 includes multiple parallel energy storage elements 141. One end of each energy storage element 141 is electrically connected to a control switch 130, and the other end is electrically connected to a grounding point. In this embodiment, the other end of the energy storage element 141 can be electrically connected to a grounded frame 160. The control switch 130 can optionally be electrically connected to any one of the energy storage elements 141. Of course, in other embodiments, the control switch 130 can also optionally be electrically connected to any one or more of the energy storage elements 141. It should be noted that the energy storage element 141 includes an inductor or a capacitor. The number of energy storage elements 141, the number of capacitors or inductors, and the corresponding inductance and capacitance values ​​can be selected according to the actual testing requirements. The capacitor can be a variable capacitor with a variable capacitance value, or it can be a fixed capacitor with a fixed capacitance value; similarly, the inductor can be a variable inductor with a variable inductance value, or it can be a fixed inductor with a fixed inductance value.

[0095] Combination Figure 9 and Figure 10 As shown, combine with if necessary Figure 1 As shown, in this embodiment, when the antenna module 100 is in the second mode, i.e., when the antenna module 100 is in the intermediate frequency mode 102 and the high frequency mode 103, the control switch 130 is in the closed position 132, and the second electrical connection point B is electrically connected to the energy storage element 141 through the control switch 130. At this time, the specific value of the energy storage element 141 connected to the control switch 130 can be determined by the specific position of the control switch 130. For example, in this embodiment, there are four energy storage elements 141, all of which are fixed capacitors with variable capacitance values, and the capacitance values ​​of the four fixed capacitors are different. When the antenna module 100 is in the intermediate frequency mode 102, the control switch 130 is electrically connected to one of the fixed capacitors, which is designated as the third capacitor C3. When the antenna module 100 is in the high frequency mode 103, the control switch 130 is electrically connected to another fixed capacitor, which is designated as the fourth capacitor C4. The capacitance value of the third capacitor C3 is greater than the capacitance value of the fourth capacitor C4. In other embodiments, the number of energy storage elements 141 may be determined based on actual test conditions.

[0096] By selecting energy storage elements 141 with different capacitance or inductance values, the equivalent capacitance or inductance value of the antenna module 100 can be changed, thereby adjusting the resonant frequency of the antenna module 100 and achieving full-band coverage.

[0097] like Figure 1 and Figure 2As shown, the first antenna radiator 120 includes a first end 121 and a second end 122 disposed opposite to each other, and a feed terminal 110 is electrically connected to the first end 121 of the first antenna radiator 120. In other words, the first electrical connection point A is located at the first end 121 of the first antenna radiator 120. The first frequency modulation circuit 140 is electrically connected to the middle of the first antenna radiator 120 via a control switch 130. With the above configuration, when the antenna module 100 is in intermediate frequency mode 102, the antenna module 100 can form an inverted F antenna (IFA) (see reference). Figure 9 (As shown). It should be noted that the first end 121 and the second end 122 mentioned above refer to the first antenna radiator 120 from left to right or from right to left 1 / 3 of the length. The middle part is the position between the first end 121 and the second end 122 of the antenna radiator, that is, the 1 / 3 to 2 / 3 position.

[0098] The antenna module 100 also includes a second antenna radiator 190. A gap structure 210 is provided between the second antenna radiator 190 and the first antenna radiator 120. The gap structure 210 is filled with an insulating layer 220 to prevent direct electrical connection between the first antenna radiator 120 and the second antenna radiator 190. In this embodiment, at least a portion of the device frame 200 serves as the first antenna radiator 120 and the second antenna radiator 190. The gap structure 210 is provided in the device frame 200, and at least a portion of the device frame 200 located on both sides of the gap structure 210 serves as the first antenna radiator 120 and the second antenna radiator 190, respectively.

[0099] Furthermore, in this embodiment, there are two second antenna radiators 190, which are disposed on both sides of the first antenna radiator 120. A gap structure 210 filled with an insulating layer 220 is provided between each of the two second antenna radiators 190 and the first antenna radiator 120. Of course, in this embodiment, there may also be only one second antenna radiator 190.

[0100] When the antenna module 100 is in the first mode 101, the equivalent circuit diagram of the antenna module 100 is as follows: Figure 8 As shown. When the antenna module 100 is working, the first antenna radiator 120 mainly participates in radiation. When the antenna module 100 is in intermediate frequency mode 102, the equivalent circuit diagram of the antenna module 100 is as follows. Figure 9 As shown. When the antenna module 100 is working, the first antenna radiator 120 mainly participates in radiation. At this time, the antenna module 100 can form an inverted-F antenna (IFA). When the antenna module 100 is in high-frequency mode 103, the equivalent circuit diagram of the antenna module 100 is as follows. Figure 10As shown. When the antenna module 100 is working, it is mainly radiated by two second antenna radiators 190 at the same time. At this time, the two surfaces of the first antenna radiator 120 and the second antenna radiator 190 are arranged opposite to each other to form a capacitor structure.

[0101] In this embodiment, the length of the slit structure 210 is less than or equal to 0.5 mm and less than or equal to 2 mm. Extensive experiments have shown that when the length of the slit structure 210 is greater than 2 mm, the distance between the first antenna radiator 120 and the second antenna radiator 190 is too long, making it difficult to form a capacitor structure between the first antenna radiator 120 and the second antenna radiator 190 when the antenna module 100 is in high-frequency mode 103. When the length of the slit structure 210 is greater than 1 mm, the distance between the first antenna radiator 120 and the second antenna radiator 190 is too short, making it easy for the first antenna radiator 120 and the second antenna radiator 190 to be directly electrically connected.

[0102] Furthermore, the length of the second antenna radiator 190 is less than the length of the first antenna radiator 120. In terms of frequency band, the longer the antenna, the lower the frequency band it can cover. By limiting the lengths of the first antenna radiator 120 and the second antenna radiator 190, when the antenna module 100 is in the first mode 101, it can more comprehensively cover the low-frequency band; and when the antenna module 100 is in the high-frequency mode 103, it can more comprehensively cover the high-frequency band.

[0103] Specifically, in this embodiment, the length of the first antenna radiator 120 is greater than or equal to 50 mm and less than or equal to 80 mm; the length of the second antenna radiator 190 is greater than or equal to 15 mm and less than or equal to 25 mm. Extensive experiments have shown that when the first antenna radiator 120 is within the above-mentioned range, by adjusting the equivalent capacitance values ​​of the first capacitor C1, the second capacitor C2, and the first frequency modulation circuit 140, the first antenna radiator 120, which mainly participates in radiation, can cover a wider frequency band when the antenna module 100 is in the first mode 101 and the intermediate frequency mode 102. When the second antenna radiator 190 is within the above-mentioned range, by adjusting the equivalent capacitance values ​​of the first capacitor C1, the second capacitor C2, and the first frequency modulation circuit 140, the second antenna radiator 190, which mainly participates in radiation, can cover a wider frequency band when the antenna module 100 is in the high frequency mode 103, thereby facilitating efficient radiation across the entire frequency band by the antenna module 100.

[0104] like Figure 11As shown, the electronic device 600 may further include one or more of the following components: a processing component 602, a memory 604, a power supply component 606, a multimedia component 608, an audio component 66, an input / output (I / O) interface 612, a sensor component 614, and a communication component 616. The communication component 616 includes the antenna module 100 described above.

[0105] Processing component 602 typically controls the overall operation of electronic device 600, such as operations associated with display, telephone calls, data communication, camera operation, and recording operations. Processing component 602 may include one or more processors 620 to execute instructions to perform all or part of the steps of the methods described above. Furthermore, processing component 602 may include one or more modules to facilitate interaction between processing component 602 and other components. For example, processing component 602 may include a multimedia module to facilitate interaction between multimedia component 608 and processing component 602.
