[0056] 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, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described exemplarily below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the attached claims. It should be noted that the features in the following embodiments and implementations may be combined with each other without conflict.

[0057] The embodiments of the present disclosure provide an antenna assembly and an electronic device. The antenna assembly can be applied to an electronic device, the electronic device includes the above antenna assembly, and the electronic device includes a first frame and a second frame, the first frame is used as the antenna body of the first antenna, the second frame is used as the antenna body of the second antenna, and a gap is provided at the first end of the antenna body of the first antenna and the second end of the antenna body of the second antenna. Considering that the antenna assembly is usually used in electronic devices, the subsequent embodiments take electronic devices as an example to describe the composition and working principle of the antenna assembly.

[0058] See also Figure 1 , the electronic device includes a first antenna A1 and a second antenna A2. The antenna body of the first antenna A1 is implemented by a first frame 20, and the antenna body of the second antenna A2 is implemented by a second frame 30; a gap 10 is provided between the first end of the first frame 20 and the second end of the second frame 30, and the width of the gap 10 is between 0.8 and 1.6 mm. In one example, the width of the gap 10 is 1 mm. The second antenna A2 includes a switching switch SW1; the switching switch SW1 is used to switch the working frequency bands of the first antenna A1 and the second antenna A2. In one example, the switching switch can be implemented by a 4SPST switch, and of course, it can also be implemented by 4 transistors (such as field effect transistors).

[0059] In this embodiment, the operating frequency bands of the two antennas can be adjusted through one switching switch, thereby reducing the number of antenna switches, which is conducive to reducing switch costs.

[0060] See also Figure 2The first antenna A1 includes a first upper frame point, and the distance between the first upper frame point and the slot 10 is in a first preset distance range. The first preset distance range is [14, 18] mm. In an example, the distance between the first upper frame point and the slot 10 is 15 mm.

[0061] In this embodiment, the first antenna A1 further includes a first capacitor. Figure 3 , the first end of the first capacitor C1 is electrically connected to the first upper frame point A, and the second end of the first capacitor C1 is grounded GND. In this way, the present embodiment can construct a quarter-mode of the intermediate frequency antenna from the slot 10 to the A position, that is, the distance between the upper frame point A at the A position and the slot 10 is one quarter of the wavelength of the intermediate frequency signal, thereby ensuring the radiation efficiency of the intermediate frequency signal.

[0062] In one embodiment, the first antenna further includes a second upper frame point. Figure 2 , the distance between the second upper frame point B and the slot 10 is within the second preset distance range, and the second preset distance range is [5, 8] mm. In one example, the distance between the second upper frame point and the slot 10 is 6.5 mm. In this way, the present embodiment can construct a high-frequency quarter mode from the slot to the first feeding point at the B position, that is, the distance from the slot 10 to the first feeding point FB1 is one quarter of the wavelength of the high-frequency signal, thereby ensuring the radiation efficiency of the high-frequency signal.

[0063] In this embodiment, continue to refer to Figure 3 , the first antenna also includes a DC signal isolation unit 41, an intermediate frequency waveform matching unit 42 and a high frequency waveform matching unit 43. The first end of the DC signal isolation unit 41 is electrically connected to the first upper frame point A, and the second end of the DC signal isolation unit 41 is electrically connected to the first end of the intermediate frequency waveform matching unit 42; the first end of the intermediate frequency waveform matching unit 42 is electrically connected to the first end of the high frequency waveform matching unit 43; the second end of the high frequency waveform matching unit 43 is electrically connected to the first feeding point. Among them, the DC signal isolation unit 41 is used to filter out the DC signal in the intermediate and high frequency signals, so as to meet the requirements of the SAR sensor. The intermediate frequency waveform matching unit 42 is used to match the initial intermediate frequency S11 waveform. The high frequency waveform matching unit 43 is used to match the initial high frequency S11 waveform.

[0064] In one embodiment, see Figure 4 The DC signal isolation unit 41 includes a second capacitor C2. A first end of the second capacitor C2 is electrically connected to the second upper frame point B, and a second end of the second capacitor C2 is electrically connected to a first end of the intermediate frequency waveform matching unit 42.

[0065] Continue to see Figure 4The intermediate frequency waveform matching unit 42 includes a second inductor L2 and a third capacitor C3. The first end of the second inductor L2 is electrically connected to the second end of the DC signal isolation unit 41, and the second end of the second inductor L2 is grounded GND. The first end of the third capacitor C3 is electrically connected to the first end of the second inductor L2, and the second end of the third capacitor C3 is electrically connected to the first end of the high frequency waveform matching unit 43.

The fourth capacitor C4 and the fourth inductor L4 can form an LC resonant circuit to improve the isolation of the N78 frequency band in the first antenna A1 and the second antenna A2; and the LC resonant circuit is equivalent to a capacitor in the high-frequency equivalent circuit and can play a role in high-frequency impedance matching.

[0068] based on Figure 2 to Figure 4 It can be seen from the first antenna shown that the first antenna A1 body branch is not set with switch tuning. It uses the switching switch in the second antenna A2 to switch the capacitor to change the low-frequency antenna isolation strip to the quarter mode of the frame point on the feeding point, thereby improving the radiation efficiency of the first antenna and the waveform ultra-wideband coverage.

[0069] In one embodiment, see Figure 2 The second antenna includes a return point P_GND and a third upper frame point C.

In one example, the distance between the return point P_GND and the gap 10 is 40 mm.

[0071] It is understandable that the return point P_GND and the third upper frame point C can construct a quarter mode of the antenna from the gap 10 to the second feeding point FB2, that is, the distance between the return point P_GND and the third upper frame point C is one quarter of the N78 frequency band signal, thereby ensuring the radiation efficiency of the second antenna A2 in the N78 frequency band.

The preset waveform matching unit is used to match the signal of the N78 frequency band.

[0075] Continue to see Figure 5 The impedance matching unit 51 includes a sixth capacitor C6, a seventh capacitor C7, an eighth capacitor C8 and a switch SW1. The first end of the sixth capacitor C6 is electrically connected to the third upper frame point C, and the second end of the sixth capacitor C6 is electrically connected to the second input end IN2 of the switch SW1; the first end of the seventh capacitor C7 is electrically connected to the third upper frame point C, and the second end of the seventh capacitor C7 is electrically connected to the third input end IN3 of the switch SW1; the first end of the eighth capacitor C8 is electrically connected to the third upper frame point, and the second end of the eighth capacitor is electrically connected to the fourth input end IN4 of the switch; the first input end IN1 of the switch SW1 is electrically connected to the second end of the fifth inductor L5, and the output end Out1 of the switch SW1 is grounded GND.
