[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0032] With the development of communication technology, 5G technology is more widely used in electronic devices. With the rapid development of 5G technology, electronic devices have integrated a variety of 5G technologies, especially in the field of antennas, which will increase the corresponding 5G frequency bands, while the size of electronic devices remains unchanged, so the antenna placement will be very compact.
[0033] In this environment, it is very necessary to design a wideband antenna, which can also save a lot of space for mobile phone terminals and provide more antenna layouts.
[0034] To overcome the problems existing in the related art, the present disclosure provides an antenna assembly and an electronic device.
[0035] An antenna assembly provided by the present disclosure includes: an antenna, wherein the antenna includes an antenna radiator, the length of the antenna radiator is greater than one quarter of the wavelength of the radiation frequency band of the antenna, and the antenna has multiple channels; and a matching circuit, wherein the matching circuit includes an adjustment module, and according to different load values of the adjustment module, the antenna matches different channels in the same frequency band.
[0036] The matching circuit of the antenna assembly disclosed in the present invention includes an adjustment module. According to different load values of the adjustment module, the antenna disclosed in the present invention matches different channels in the same frequency band. Such a setting can tune each channel so that more channels can be tuned in one frequency band, and since a single channel is matched separately, the channel performance can also be better.
[0037] Figure 1 It is a schematic structural diagram of an antenna assembly according to an exemplary embodiment. Figure 2 is a schematic diagram of a matching circuit according to an exemplary embodiment.
[0038] like Figure 1 and Figure 2As shown, the antenna assembly 10 of the present disclosure may include an antenna ANT and a matching circuit 200, and the antenna ANT may include an antenna radiator 110. In the present disclosure, the length of the antenna radiator 110 may be greater than a quarter wavelength of the radiation frequency band of the antenna. With such a configuration, compared to an antenna in which the length of the antenna radiator is equal to a quarter wavelength of the radiation frequency band of the antenna, the antenna ANT of the present disclosure has a larger radiation range, can radiate more frequency bands, or can have a wider frequency band.
[0039] like Figure 1 As shown, the antenna ANT may have a ground point 111, and the end 113 of the antenna ANT and the ground point 111 are respectively located on both sides of the excitation point 112. The length of the antenna radiator 110 may be the length between the end 113 of the antenna ANT and the ground point 111.
[0040] In the exemplary embodiment of the present disclosure, Figure 1 As shown, the antenna radiator 110 can extend in a first direction (from the end 113 of the antenna ANT and the ground point 111). That is, most of the antenna radiator 110 can extend along one direction. Therefore, in such an embodiment, the length of the antenna radiator 110 can be the length in the first direction. When the antenna assembly 10 is set in an electronic device, most of the antenna radiator 110 can be located on a side frame of the electronic device.
[0041] However, the present disclosure is not limited to the above embodiments. In some embodiments, the antenna radiator 110 may also include multiple sides extending in different directions. For example, the antenna radiator 110 may be L-shaped. In such an embodiment, the length of the antenna radiator 110 may be the sum of the lengths extending in different directions. When the antenna assembly 10 is provided in an electronic device in this way, most of the antenna radiator 110 may be located at multiple side frames of the electronic device. For example, one side of the antenna radiator 110 may be a frame of the head of the electronic device, and the other side may be a side frame of the electronic device. Alternatively, one side of the antenna radiator 110 may be a frame of the bottom of the electronic device, and the other side may be a side frame of the electronic device.
[0042] In the exemplary embodiment of the present disclosure, the length of the antenna radiator 110 may be 20 mm-35 mm. For example, the length of the antenna radiator 110 may be about 24 mm, about 26 mm, about 28 mm, about 30 mm or about 32 mm.
[0043] In the present disclosure, the matching circuit 200 may include an adjustment module 231, and the adjustment module 231 may have different load values. The load value of the adjustment module 231 may match the impedance of the antenna ANT. For different frequency bands covered by the antenna ANT, the antenna ANT will switch to different channels, and the impedance of the antenna ANT changes. In this case, the adjustment module 231 may have a load value that matches the impedance, improve the efficiency of the antenna ANT, and enable the antenna ANT to cover different frequency bands.
[0044] In the present disclosure, the load value may refer to the resistance value of a resistor, the capacitance value of a capacitor, the inductance value of an inductor, or the resistance value of other components installed in the adjustment module 231 .
[0045] In the present disclosure, the antenna ANT can cover at least one of the low frequency band (700-960MHz), the medium frequency band (1710-2690MHz) and the high frequency band (3300-4200MHz). For example, the antenna ANT can cover the low frequency band, the medium frequency band and the high frequency band at the same time. By adjusting the module 231 to have different load values, the antenna ANT can switch among the low frequency band, the medium frequency band and the high frequency band to achieve one antenna covering the low frequency band, the medium frequency band and the high frequency band.
[0046] In the exemplary embodiment of the present disclosure, Figure 2 As shown, the adjustment module 231 may include an adjustment unit 211, and the adjustment unit 211 may have different capacitance values so that the adjustment module 231 has different load values. In this case, the adjustment unit 211 may be a capacitor.
[0047] In the present disclosure, for example, the adjustment unit 211 may be a variable capacitor, and the capacitance value of the variable capacitor may change, so that the adjustment unit 211 may have different capacitance values, and the adjustment module 231 may have different load values.
[0048] In the present disclosure, for example, the capacitance value of the variable capacitor may be 0.15 pf to 3.9 pf. For example, the capacitance value of the variable capacitor may be 3.6 pf. For example, the capacitance value of the variable capacitor may be 3.82 pf.
[0049] In the exemplary embodiment of the present disclosure, Figure 2 As shown, the matching circuit 200 may further include a plurality of matching units, for example, may include a first matching unit 201 , and the first matching unit 201 may have a load value corresponding to the impedance of the antenna ANT. The first matching unit 201 may be connected to the adjustment unit 211 .
[0050] In the exemplary embodiment of the present disclosure, Figure 2As shown, the regulating module 231 includes a first switch 221, a first end of the first switch 221 is connected to the regulating unit 211, and the other end of the first switch 221 is connected to the first matching unit 201. For example, the first matching unit 201 can be connected between the other end of the first switch 221 and the regulating unit 211, and the first switch is turned on or off so that the regulating module 231 has different load values.
[0051] like Figure 2 As shown, when the first switch 221 is turned on, the first matching unit 201 connected to the first switch 221 is connected to the circuit of the adjustment module 231, so that the load value of the adjustment module 231 includes the capacitance value of the adjustment unit 211 and the load value of the first matching unit 201.
[0052] like Figure 2 As shown, when the first switch 221 is disconnected, the first matching unit 201 connected to the first switch 221 is not connected to the circuit of the adjustment module 231, so the load value of the adjustment module 231 includes the capacitance value of the adjustment unit 211 but not the load value of the first matching unit 201.
[0053] like Figure 2 As shown, in the exemplary embodiment of the present disclosure, the matching circuit 200 further includes a second switch 222, and the second switch 222 is set to be grounded, that is, the second switch 222 is connected to the ground point G. One end of the second switch 222 can be connected to the ground point G of the matching circuit 200, and the other end of the second switch 222 can be connected to the connection node N between the first matching unit 201 and the third matching unit 203.
[0054] Reference Figure 2 , taking the example that the antenna ANT can cover the low frequency band, the medium frequency band and the high frequency band at the same time, the following explains how the antenna ANT switches different channels:
[0055] The first switch 221 is turned on, the second switch 222 is turned off, the adjustment unit 211 has a first capacitance value, which may be 3.82 pf, and the antenna ANT is switched to the first channel. In the present disclosure, the first channel may be a low-frequency transmission channel. However, the present disclosure is not limited thereto, and in some embodiments, the first channel may also be other channels.
[0056] The first switch 221 is disconnected, the second switch 222 is disconnected, the adjustment unit 211 has a second capacitance value, the second capacitance value may be 3.82 pf, and the antenna ANT is switched to the second channel. In the present disclosure, the second channel may be an intermediate frequency transmission channel. However, the present disclosure is not limited thereto, and in some embodiments, the second channel may also be other channels.
[0057] The first switch 221 is disconnected, the second switch 222 is turned on, the adjustment unit 211 has a third capacitance value, the third capacitance value may be 3.82 pf, and the antenna ANT is switched to the third channel. In the present disclosure, the third channel may be a high-frequency transmission channel. However, the present disclosure is not limited thereto, and in some embodiments, the third channel may also be other channels.
[0058] The first switch 221 is disconnected, the second switch 222 is turned on, the adjustment unit 211 has a fourth capacitance value, the fourth capacitance value may be 3.37 pf, and the antenna ANT is switched to the fourth channel. In the present disclosure, the fourth channel may be a low-frequency receiving channel. However, the present disclosure is not limited thereto, and in some embodiments, the fourth channel may also be other channels.
[0059] The first switch 221 is disconnected, the second switch 222 is turned on, the adjustment unit 211 has a fifth capacitance value, the fifth capacitance value may be 3.06 pf, and the antenna ANT is switched to the fifth channel. In the present disclosure, the fifth channel may be an intermediate frequency receiving channel. However, the present disclosure is not limited thereto, and in some embodiments, the fifth channel may also be other channels.
[0060] The first switch 221 is disconnected, the second switch 222 is turned on, the adjustment unit 211 has a sixth capacitance value, the sixth capacitance value may be 2.79, and the antenna ANT is switched to the sixth channel. In the present disclosure, the sixth channel may be a high-frequency receiving channel. However, the present disclosure is not limited thereto, and in some embodiments, the sixth channel may also be other channels.
[0061] According to the matching circuit 200 and the combined tuning of the first switch 221 / the second switch 222 of the present disclosure, the antenna ANT can switch to multiple states within a single band frequency.
[0062] like Figure 2 As shown, the matching circuit 200 may further include an inductor 206, one end of which may be connected to the second switch 222 and the capacitor 205. The other end of the inductor 206 may be connected to the connection node N.
[0063] Figure 3 It is a schematic diagram showing multiple channels of an antenna assembly according to an exemplary embodiment. Figure 3 It is shown in the figure that the antenna ANT includes the B3 (band 3) frequency band. Taking the B3 frequency band as an example, an embodiment of switching multiple channels within a single frequency band is illustrated.
[0064] like Figure 3 As shown, the antenna ANT switches to at least five states within a single band frequency (for example, Figure 3 As shown in the curves A, B, C, D, and E in the figure, TX_LM channel, TX_H channel, RX_L channel, RX_M channel, and RX_H channel can be cut out in band3.
[0065] Figure 4 FIG. 1 is a schematic diagram of a Smith circle of an antenna assembly according to an exemplary embodiment. Figure 4 As shown, during the debugging process of the antenna ANT, the medium and high frequencies of the antenna ANT can be debugged to the lower 3rd and 4th quadrants and the inductance can be pulled close to 50Ω. It should be noted that the position of about 50Ω is for mobile phone antennas. In other electronic devices, the inductance can also be pulled close to 70Ω. This disclosure does not make specific limitations, as long as it can meet the relevant industry standards.
[0066] Figure 5 The diagram is a Smith circle diagram of an antenna assembly according to an exemplary embodiment. In the debugging process of the antenna ANT, the intermediate frequency can be debugged by connecting an inductor in series with a capacitor in parallel and a capacitor in series near the short-circuit end on the Smith circle.
[0067] like Figure 2 As shown, in the exemplary embodiment of the present disclosure, the matching circuit 200 may further include a second matching unit 202 and a third matching unit 203 respectively connected in series with the adjustment module 231. Figure 2 As shown, the second matching unit 202 is connected to one end of the adjustment module 231 , and the third matching unit 203 is connected between the other end of the adjustment module 231 and the output end F.
[0068] In the present disclosure, the second matching unit 202 may have a load value corresponding to the impedance of the antenna ANT. Figure 2 As shown, the second matching unit 202 may be connected between the input end of the matching circuit 200 and the adjustment module 231 .
[0069] In the present disclosure, the third matching unit 203 may have a load value corresponding to the impedance of the antenna ANT. Figure 2 As shown, the third matching unit 203 may be connected between the first matching unit 201 and the output terminal F of the matching circuit 200 .
[0070] like Figure 1 and Figure 2 As shown, the output terminal F may be an excitation signal terminal. The matching circuit 200 may be connected to the excitation point 112 of the antenna radiator 110 through the output terminal F. The antenna ANT may have a ground point 111, and the end 113 of the antenna ANT and the ground point 111 are located at both sides of the excitation point 112 respectively.
[0071] like Figure 2As shown, in the exemplary embodiment of the present disclosure, the plurality of matching units may be one or more of a capacitor, a resistor, and an inductor. For example, the first matching unit 201 may be a resistor. The second matching unit 202 may be an inductor. The third matching unit 203 may be a resistor. The present disclosure does not make any specific limitation, as long as the relevant functions of the antenna ANT can be realized.
[0072] like Figure 2 As shown, in the exemplary embodiment of the present disclosure, the second switch 222 can be connected in parallel with the capacitor 205, and the capacitor 205 can be grounded. That is, the matching circuit 200 is grounded through the capacitor 205. Such a setting can make the antenna ANT suspended, and then can be configured as a sensing end of a SAR sensor for sensing the electromagnetic wave absorption ratio.
[0073] SAR (Specific Absorption Rate) is the electromagnetic wave energy absorption ratio of mobile phones and other terminals or wireless products.
[0074] Under the influence of external electromagnetic fields, an induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate currents, resulting in the absorption and dissipation of electromagnetic energy. SAR is often used in biological dosimetry to characterize this physical process. The meaning of SAR is the electromagnetic power absorbed or consumed by a unit mass of human tissue.
[0075] The SAR value generally refers to the heat energy generated by electromagnetic waves in mobile phone products, which is a measure of the impact on the human body.
[0076] In the present disclosure, the antenna radiator 110 can be used as a sensing end to sense the electromagnetic wave absorption ratio, and can use the principle of human tissue dissipating electromagnetic energy to accurately determine whether the corresponding antenna area is blocked by an object.
[0077] Since the electromagnetic waves of the communication antenna have a certain impact on the human body, for example, the SAR value indicates how much the heat energy of the mobile phone will affect the human body. The larger the value, the greater the impact on the human body, and vice versa. The detection data of the capacitance detection end can also be used to control the terminal's electromagnetic waves within a certain range when there is an object blocking it, so as to minimize the impact on the human body.
[0078] The United States and Europe have already set regulations on the SAR (Specific Absorption Rate) of mobile phone radiation to the human body. The US standard is 1.6W / kg (1 gram) and the European standard is 2.0W / kg (10 grams). The safety standard value for mobile phones announced by the Federal Communications Commission (FCC) of the United States is 1.6, so as long as the SAR value of a mobile phone is below 1.6, it is a product within the safety standard.
[0079] In the present disclosure, the antenna radiator 110 of the antenna ANT can also serve as a sensing end of the SAR sensor, thereby increasing the sensing range of the SAR sensor and obtaining a more accurate SAR value.
[0080] Based on the same concept, the present disclosure also provides an electronic device, comprising the antenna assembly 10 as described in any one of the aforementioned embodiments.
[0081] Figure 6 FIG. 1 is a schematic diagram showing the structure of an electronic device according to an exemplary embodiment. Figure 6 As shown, in an exemplary embodiment of the present disclosure, the electronic device 30 may include a frame 100, and at least a portion of the frame 100 may be an antenna radiator 110. The electronic device 30 may also include a display screen 32.
[0082] like Figure 1 and Figure 6 As shown, in an exemplary embodiment of the present disclosure, the electronic device 30 may include a button 31 , and the frame 100 is provided with an opening 101 for accommodating the button 31 to pass through, and at least a portion of the frame 100 surrounding the opening 101 may be an antenna radiator 110 .
[0083] Such a configuration utilizes the frame 100 around the button 31. Since the pressing function is to be realized, the antenna clearance condition around the button 31 is generally better. Setting the antenna here can make the antenna have a better radiation range.
[0084] For the antenna ANT of the present disclosure, relevant tests on the antenna radiation effect are carried out by taking the above embodiment as an example. The test results are shown in Table 1.
[0085] Table 1
[0086]
[0087] In Table 1, L represents a low frequency channel of the antenna ANT, M represents a medium frequency channel of the antenna ANT, and H represents a high frequency channel of the antenna ANT.
[0088] In Table 1, PRX is the main receiving antenna, responsible for sending and receiving RF signals. DRX is the diversity receiving antenna, responsible for receiving RF signals. TRP (total radiated power) is the total radiated power of antenna ANT. TIS (total istropic sensitivity) is the total isotropic sensitivity of antenna ANT.
[0089] According to Table 1, it can be seen that the channel-level switching antenna ANT provided in the present disclosure can be optimized separately for PRX and DRX, so that the performance is greatly improved. For example, when the antenna is in DRX, the sensitivity TIS is improved by 3db compared with PRX.
