Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

As shown in fig. 1 and 2, the present application discloses an electronic device 600, the electronic device 600 includes an antenna module 100 for receiving and transmitting signals. In this embodiment, the electronic device 600 is a mobile phone. A handset may typically have one or two sets of antenna modules 100. When the mobile phone has two sets of antenna modules 100, one set of antenna module 100 is located at the top of the mobile phone, and the other set of antenna module 100 is located at the bottom of the mobile phone. Of course, in other embodiments, the electronic device 600 may also be other devices with the antenna module 100 and having a communication function, such as: computers, tablet devices, electronic books, watches, headsets, medical devices, fitness devices, personal digital assistants, and the like.

The electronic device 600 further includes a device middle frame 200, and the antenna module 100 is disposed inside the device middle frame 200. The device middle frame 200 can support and protect the antenna module 100 and other electronic components.

As shown in the figure, in the present embodiment, the antenna module 100 includes a feeding terminal 110, a first antenna radiator 120, a control switch 130, and a first frequency modulation circuit 140. The first tuning circuit 140 can adjust the equivalent capacitance or inductance of the antenna module 100.

Wherein the first antenna radiator 120 is electrically connected to the feeding terminal 110. The first frequency modulation circuit 140 has one end electrically connected to the ground point and the other end electrically connected to the first antenna radiator 120 through the control switch 130. The control switch 130 is switchable between an open position 131 and a closed position 132. Referring to fig. 2, when the control switch 130 is switched to the off position 131, the first fm circuit 140 and the first antenna radiator 120 are disconnected. Referring to fig. 1, when the control switch 130 is switched to the closed position 132, the control switch 130 can be used as a conductive wire, and two ends of the conductive wire are electrically connected to the first frequency modulation circuit 140 and the first antenna radiator 120, respectively, so that the first frequency modulation circuit 140 and the first antenna radiator 120 are electrically connected.

The antenna module 100 can be switched between a first mode and a second mode.

As shown in fig. 2, when the antenna module 100 is in the first mode 101, a frequency band covered by the antenna module 100 is the first frequency band. As shown in fig. 1, 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, a frequency band covered by the antenna module 100 is referred to as a low frequency band, and therefore, the first mode 101 is also referred to as a low frequency mode. The frequency range covered by the antenna module 100 is about 700MHz to 960MHz, in other words, the antenna module 100 operates in 700MHz to 960 MHz. Meanwhile, in the present embodiment, the second mode further includes an intermediate frequency mode 102 and a high frequency mode 103 (shown with reference to fig. 9 and 10). When the antenna module 100 is in the if mode 102 of the second mode, a frequency band covered by the antenna module 100 is referred to as an if band, and the frequency band covered by the antenna module 100 is about 1710MHz to 2170MHz, in other words, the antenna module 100 operates at 1710MHz to 2170 MHz. Correspondingly, the first frequency band is 1710MHz to 2170 MHz. When the antenna module 100 is in the high-frequency mode 103 of the second mode, a frequency band covered by the antenna module 100 is referred to as a middle frequency band, and the frequency band covered by the antenna module 100 is about 2300MHz to 2690MHz, in other words, the antenna module 100 operates at 2300MHz to 2690 MHz. Of course, in other embodiments, the second mode is also only the intermediate frequency mode 102, or only the high frequency mode 103. The second frequency range is 2300MHz to 2690 MHz.

As shown in fig. 3, 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 electrically connects the feeding end 110. No matter 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 ground point through a capacitor or an inductor, so as to implement grounding. In the above design, when the first antenna radiator 120 is located in the first mode 101 (low frequency mode), radiation is mainly taken part in by the first antenna radiator 120. At this time, the current on the first antenna radiator 120 is as shown in fig. 4. Since the low-frequency current zero of the antenna is located at the end of the low-frequency branch of the antenna, the low-frequency current zero of the antenna at the terminal is located on the left side of the antenna. And, a current strong point is generated at both the first electrical connection point a and the second electrical connection point B. When the user uses the mode of holding the terminal by the right hand to carry out communication, the right hand is closer to the left side of the antenna. The hand mold causes the low frequency to be low, and absorbs the antenna efficiency, and the communication performance is degraded. At the same time, the current intensity at the positions of the first electrical connection point a and the second electrical connection point B is severely affected. When the user uses the left hand to hold the terminal for communication, the left hand is far away from the left side of the antenna, so that the influence on the communication performance is small, and the influence on the current strong points at the positions of the first electric connection point A and the second electric connection point B is small. Thus, the low frequency right hand mode performance is worse than the left hand mode performance by substantially 3 dB.

Based on this, the antenna disclosed in the embodiment of the present application is to solve the problem that the performance of the antenna in the low-frequency left and right head-hand modes is unbalanced, which affects the communication quality of the terminal in the head-hand mode state.

As shown in fig. 2, in the present embodiment, the first electrical connection point a of the first antenna radiator 120 is electrically connected to the feeding terminal 110, and the second electrical connection point B of the first antenna radiator 120 is electrically connected to the control switch 130.

When the antenna module 100 is in the first mode 101, the first antenna radiator 120 is disconnected from the ground point at a position far from the feeding end 110. In other words, when the control switch 130 is switched to the open position 131, the second electrical connection point B is disconnected from the first frequency modulation circuit 140 and the grounding point. At this time, the current on the first antenna radiator 120 is as shown in fig. 5. With the above arrangement, when the antenna module 100 is in the first mode 101, the first antenna radiator 120 has only one current strong point in the first mode 101, that is, the current strong point exists at the first electrical connection point a. A large number of experiments show that when the antenna module 100 is in the first mode 101 (low frequency mode), the first antenna radiator 120 has only one current strong point, and no matter whether the user uses the right hand or left hand to hold the terminal for communication, the difference between the two scenarios in the influence on the current strong point is small. In other words, when the user holds the electronic device 600 with the left hand or the right hand, the influence on the current intensity point when the user holds the electronic device with the left hand or the right hand can be reduced, and the difference of the influence on the current intensity point when the user holds the electronic device with the left hand or the right hand can be reduced, so that the phenomenon that the performance of the left head module and the performance of the right head module are unbalanced is reduced, and the communication quality of the terminal in the head module state is ensured.

As shown in fig. 1, when the antenna module 100 is in the second mode, the control switch 130 is switched to the closed position 132, and the first frequency modulation circuit 140 is electrically connected to the first antenna radiator 120. At this time, the first tuning circuit 140 may adjust its capacitance or inductance value, thereby adjusting the middle-high frequency resonant frequency of the antenna module 100, and realizing full-band coverage.

As shown in fig. 1 and fig. 2, in the present embodiment, the antenna module 100 includes a second frequency modulation circuit 150, and two ends of the second frequency modulation circuit 150 are electrically connected to the feeding terminal 110 and the first antenna radiator 120, respectively. The second tuning circuit 150 includes a first capacitor C1, and two ends of the first capacitor C1 are electrically connected to the feeding terminal 110 and the first electrical connection point a of the first antenna radiator 120, respectively. In the present embodiment, the first capacitor C1 is a variable capacitor. No matter 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 of the first capacitor C1, for example, by reducing the capacitance of the equivalent capacitor, the resonant frequency of the antenna module 100 can be increased, thereby achieving full-band coverage.

Further, the second frequency modulation circuit 150 further includes a second capacitor C2. One end of the second capacitor C2 is electrically connected to the ground point. The other end of the second capacitor C2 is electrically connected between the feeding terminal 110 and the first capacitor C1 (see fig. 1 and 2). Alternatively, the other end of the second capacitor C2 is electrically connected between the first capacitor C1 and the first antenna radiator 120 (see fig. 6). In this embodiment, the second capacitor C2 is a variable capacitor, and the capacitance of the second capacitor C2 is adjusted, and the first capacitor C1 and the first capacitor C1 can be used in combination, so that the resonant frequency of the antenna module 100 is adjusted by adjusting the equivalent capacitance of the antenna module 100, for example, by reducing the capacitance of the equivalent capacitor, the resonant frequency of the antenna module 100 can be increased, and full-band coverage is achieved.

In this embodiment, no matter the antenna module 100 is in the first mode 101 or the second mode, the first capacitor C1 and the second capacitor C2 can be adjusted, so as to adjust the resonant frequency of the antenna module 100, and further achieve full-band coverage. Meanwhile, the change of the resonant position can be realized by adjusting the second capacitor C2, so that the impedance is adjusted, the transmitter is better matched, the return loss is effectively reduced, and the radiation efficiency is improved.

In this embodiment, as shown in fig. 7, the device middle frame 200 further includes a grounding middle frame 160 and a control circuit board 170 made of metal. The grounding middle frame 160 is grounded, and an end of the first frequency modulation circuit 140 away from the control switch 130 can be electrically connected to the grounding middle frame 160, so that an end of the first frequency modulation circuit 140 is electrically connected to the grounding point. One end of the second capacitor C2 can be electrically connected to the grounding middle frame 160, so that one end of the second capacitor C2 is electrically connected to the grounding point. The first capacitor C1 and the second capacitor C2 in the second fm circuit 150, the control switch 130, and the first fm circuit 140 may all be fixedly connected to the control circuit board 170. The control circuit board 170 is further provided with a control chip, and the control chip can be electrically connected to the feeding terminal 110 and the control switch 130, and can control the feeding terminal and the control switch.

As shown in fig. 1, fig. 2 and fig. 7, the first frequency modulation circuit 140 includes a plurality of energy storage elements 141 connected in parallel, one end of each energy storage element 141 is electrically connected to the control switch 130, and the other end is electrically connected to the ground point. In this embodiment, the other end of the energy storage element 141 may be electrically connected to the grounding middle frame 160. The control switch 130 is optionally electrically connected to any one of the energy storage elements 141. Of course, in other embodiments, the control switch 130 may also be optionally 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 the energy storage elements 141, the number of capacitors or inductors, and the corresponding inductance and capacitance values can be selected according to the actual test requirements. The capacitor may be a variable capacitor having a variable capacitance value, or may be a fixed capacitor having an invariable capacitance value; similarly, the inductor may be a variable inductor having a variable inductance value, or may be a fixed inductor having a non-variable inductance value.

Referring to fig. 9 and 10, and optionally fig. 1, in the present embodiment, when the antenna module 100 is in the second mode, that is, when the antenna module 100 is in the intermediate frequency mode 102 and the high frequency mode 103, the control switch 130 is both 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 position of the control switch 130 can be used to determine the value energy storage element 141 to which the control switch 130 is specifically connected. For example, in the present embodiment, the number of the energy storage elements 141 is 4, and the four energy storage elements 141 are all fixed capacitors whose capacitance values are invariable, and the capacitance values of the four fixed capacitors are different. When the antenna module 100 is in the if mode 102, the control switch 130 is electrically connected to one of the fixed capacitors, and the fixed capacitor is used 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 used as the fourth capacitor C4. The capacitance value of the third capacitor C3 is larger than that of the fourth capacitor C4. In other embodiments, the number of the energy storage elements 141 may be determined according to actual test conditions.

The energy storage element 141 with different capacitance or inductance values is selected to change the equivalent capacitance or inductance of the antenna module 100, so as to adjust the resonant frequency of the antenna module 100, and further realize the full-band coverage.

As shown in fig. 1 and 2, the first antenna radiator 120 includes a first end portion 121 and a second end portion 122 which are oppositely disposed, and the feeding terminal 110 is electrically connected to the first end portion 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 tuning circuit 140 is electrically connected to the middle portion of the first antenna radiator 120 through the control switch 130. With the above arrangement, when the antenna module 100 is in the intermediate frequency mode 102, the antenna module 100 can form an Inverted F Antenna (IFA) (shown with reference to fig. 9). It should be noted that the first end 121 and the second end 122 are portions 1/3 of the first antenna radiator 120 from left to right or from right to left. The middle is the position between the first end 121 and the second end 122 of the antenna radiator, i.e. the position 1/3 to 2/3.

The antenna module 100 further includes a second antenna radiator 190, a gap structure 210 is disposed between the second antenna radiator 190 and the first antenna radiator 120, and an insulating layer 220 is filled in the gap structure 210 to block the first antenna radiator 120 and the second antenna radiator 190 from being directly electrically connected. In this embodiment, at least part of the device middle frame 200 serves as the first antenna radiator 120 and the second antenna radiator 190. The device middle frame 200 is provided with a slit structure 210, and at least portions of the device middle frame 200 located at both sides of the slit structure 210 are respectively used as the first antenna radiator 120 and the second antenna radiator 190.

Further, in this embodiment, the number of the second antenna radiators 190 is two, the two second antenna radiators 190 are disposed on two sides of the first antenna radiator 120, and a gap structure 210 filled with an insulating layer 220 is disposed between each of the two second antenna radiators 190 and the first antenna radiator 120. Of course, in the embodiment, the number of the second antenna radiators 190 may also be 1.

When the antenna module 100 is in the first mode 101, an equivalent circuit diagram of the antenna module 100 is shown in fig. 8. When the antenna module 100 is operated, the first antenna radiator 120 mainly participates in radiation. When the antenna module 100 is in the if mode 102, an equivalent circuit diagram of the antenna module 100 is shown in fig. 9. When the antenna module 100 is operated, the first antenna radiator 120 mainly participates in radiation, and at this time, the antenna module 100 may form an Inverted F Antenna (IFA). When the antenna module 100 is in the high-frequency mode 103, an equivalent circuit diagram of the antenna module 100 is shown in fig. 10. When the antenna module 100 operates, two second antenna radiators 190 mainly participate in radiation at the same time, and at this time, two surfaces of the first antenna radiator 120 and the second antenna radiator 190, which are oppositely disposed, form a capacitor structure.

In the present embodiment, the length of the seam-breaking structure 210 is less than or equal to 0.5 mm and less than or equal to 2 mm. It has been shown through a lot of experiments that when the length of the slot-break structure 210 is greater than 2 mm, the distance between the first antenna radiator 120 and the second antenna radiator 190 is excessively long, and it is difficult to form a capacitive structure between the first antenna radiator 120 and the second antenna radiator 190 when the antenna module 100 is in the 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, and the first antenna radiator 120 and the second antenna radiator 190 are easily and directly electrically connected.

Further, the length of the second antenna radiator 190 is smaller than the length of the first antenna radiator 120. In terms of frequency bands, the longer the length of the antenna, the lower the frequency band can be covered. 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, the low frequency band can be more completely covered; when the antenna module 100 is in the high frequency mode 103, the high frequency band can be covered more completely.

Specifically, in the present embodiment, the length of the first antenna radiator 120 is equal to or greater than 50 mm, and equal to or less than 80 mm; the length of the second antenna radiator 190 is equal to or greater than 15 mm and equal to or less than 25 mm. A number of experiments show that when the first antenna radiator 120 is in the above range, the first antenna radiator 120 mainly participating in radiation can cover a wider frequency band when the antenna module 100 is in the first mode 101 and the middle frequency mode 102 by adjusting the equivalent capacitance values of the first capacitor C1, the second capacitor C2, and the first fm circuit 140. When the second antenna radiator 190 is in the above range, the equivalent capacitance values of the first capacitor C1, the second capacitor C2 and the first frequency modulation circuit 140 can be adjusted, so that when the antenna module 100 is located in the high-frequency mode 103, the second antenna radiator 190 mainly participating in radiation can cover a wider frequency band, thereby facilitating the antenna module 100 to realize efficient radiation in the full frequency band.
