Currently, mobile phones use a planar inverted-F antenna (PIFA) to communicate with other devices. However, the traditional PIFA antenna needs to design a relatively complex current path when constructing a dual-band, and the paths are not independent of each other, which causes the problem that the resonant frequency points are not easy to control independently.

[0008] a part between the feeding point and the first short-circuit point on the first radiator is a component part of a first radiation path;

[0009] a part between the feeding point and the second short-circuit point on the first radiator is a component part of a second radiation path;

[0010] wherein the frequency of the wireless signal radiated by the first radiation path is different from the frequency of the wireless signal radiated by the second radiation path.

[0013] In some embodiments, the second radiator has a first end arranged close to the feeding point and a second end arranged away from the feeding point.

[0014] The antenna module further comprises:

[0015] a third short-circuit point located at the second end of the second radiator.

[0016] In some embodiments, the first radiation path accounts for a ratio between a length of the first radiator and a length of the second radiator, and the ratio is within a threshold range.

[0017] In some embodiments, the first radiator and the second radiator are located on the same plane.

[0018] In some embodiments, the first radiator has a rectangular shape, and the second radiator has an inverted L shape.

[0019] In some embodiments, a spacing distance between the second radiator and the first radiator is within a range of 0.4 mm to 0.6 mm.

[0020] In some embodiments, the first radiation path accounts for a length of the first radiator, and the length of the first radiation path is less than a length of the second radiation path.

[0021] The first radiation path radiates a center frequency of a wireless signal, and the center frequency of the wireless signal radiated by the first radiation path is greater than a center frequency of a wireless signal radiated by the second radiation path.

[0022] In some embodiments, a distance between the feed point and the shorting point is used to adjust a bandwidth of the antenna module.

[0023] A second aspect of the embodiments of the present disclosure provides a terminal device, comprising:

[0024] a frame body;

[0025] a printed circuit board located in a receiving space formed by the frame body, and having a ground layer and a feed link layer arranged to be spaced apart from the ground layer;

[0026] the antenna module as in the first aspect above is located on a surface of the frame body facing the printed circuit board, and is arranged to be spaced apart from the printed circuit board;

[0027] a first connecting sheet connecting the feed point of the antenna module and the feed link layer;

[0028] a second connecting sheet connecting the shorting point of the antenna module and the ground layer.

[0030] The technical solutions provided by the embodiments of the present disclosure can include the following beneficial effects:

[0031] The antenna module according to an example embodiment includes a feed point, a first short-circuit point and a second short-circuit point. The first short-circuit point and the second short-circuit point are located at different sides of the feed point. That is, the first short-circuit point and the second short-circuit point are different short-circuit points distributed at different sides of the feed point. Thus, a first radiation path formed by the first short-circuit point and the feed point and a second radiation path formed by the second short-circuit point and the feed point are independent of each other, and do not cross or overlap. When the antenna module radiates wireless signals, different radiation paths can radiate wireless signals of different frequencies independently, and the flexibility of the antenna module control is improved.

[0041] The exemplary embodiments will be described in detail below with reference to the drawings. In the following description, the same numbers are used to denote the same elements throughout the several views. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0042] Figure 1 Fig. 1 is a structural diagram of an antenna module according to an exemplary embodiment. Figure 1 As shown in Fig. 1, the antenna module includes: Figure 2

[0043] a first radiator 101;

[0044] a feed point 102 on the first radiator 101;

[0045] short-circuit points including a first short-circuit point 103 and a second short-circuit point 104; the first short-circuit point 103 and the second short-circuit point 104 are respectively located on different sides of the feed point 102;

[0046] a portion between the feed point 102 and the first short-circuit point 103 on the first radiator 101 is a component of a first radiation path;

[0047] a portion between the feed point 102 and the second short-circuit point 104 on the first radiator 101 is a component of a second radiation path;

[0048] wherein the first radiation path radiates wireless signals at a different frequency from the second radiation path.

[0049] The antenna module described above is applied in a mobile communication scenario. A terminal device having the antenna module can establish communication with a base station through the antenna module to transmit and receive wireless signals, and thus can realize communication between the terminal device and an external device other than the terminal device. For example, the terminal device can be a smartphone, and the external device can be a tablet computer. For another example, the terminal device can be a tablet computer, and the external device can be a notebook computer, without limitation of the present disclosure.

[0050] The first radiator described above is composed of a conductive material and can convert electrical signals into wireless signals. The first radiator can be used to transmit and receive wireless signals in a frequency range of 300 MHz to 6 GHz. For example, the first radiator can transmit and receive wireless signals in B1, B3 and B39 frequency bands, and can also transmit and receive wireless signals in Wi-Fi 2.4 GHz or 5 GHz frequency bands.

[0051] ​In the embodiments of the present disclosure, the terminal device comprises a shell, and the first radiator is arranged on the shell. The shell comprises a middle frame for carrying various functional modules in the terminal device and a bezel surrounding the outside of the middle frame. The first radiator can be arranged on the middle frame of the terminal device, and can also be arranged on the bezel of the terminal device, which is not limited in the embodiments of the present disclosure.

[0052] The first radiator described above can be a radiator formed by a laser direct structuring process (Laser-Direct-structuring), and can also be a radiator formed by a flexible circuit board process.

[0053] The feeding point described above is used for transmitting electrical signals. The feeding point is connected with the first radiator. The feeding point can transmit the received first electrical signals to the first radiator, so that the first radiator radiates wireless signals under the excitation of the first electrical signals. The feeding point can also receive second electrical signals obtained by the first radiator converting wireless signals, and transmit the second electrical signals to a radio frequency front-end component of the antenna module, to complete the reception of wireless signals in the antenna module.

[0054] In the embodiments of the present disclosure, the short circuit point described above is a grounding point of the first radiator, and can be connected to a grounding layer of a printed circuit board. The feeding point described above can be connected to a feeding point link layer on the printed circuit board, that is, connected with a radio frequency front-end component located on the printed circuit board.

[0055] The short circuit point described above comprises a first short circuit point and a second short circuit point. The first short circuit point and the second short circuit point are located on different sides of the feeding point, and comprise that the first short circuit point and the second short circuit point are respectively located on opposite sides of the feeding point. In the embodiment, the first short circuit point and the second short circuit point are respectively arranged on opposite sides of the feeding point, so that the part between the feeding point and the first short circuit point and the part between the feeding point and the second circuit point are mutually non-overlapping parts, and further so that the first radiation path and the second radiation path are mutually independent.

[0056] It should be noted that the first radiator has a first radiation path and a second radiation path. The frequency of the radiation wireless signal of the first radiation path is different from the frequency of the radiation wireless signal of the second radiation path, which can enable the first radiator to radiate wireless signals of different frequencies at the same time, and realize dual-frequency operation of the antenna module.

[0057] Exemplarily, the feeding point can be arranged at 1 / 2 position of the first radiator, the first short circuit point can be arranged at 1 / 4 position of the first radiator, and the second short circuit point can be arranged at 3 / 4 position of the first radiator.

[0058] In the embodiment, as shown in FIG. 1, the first short circuit point 102 and the second short circuit point 103 are respectively arranged on opposite sides of the feeding point 101. Figure 2As shown, the first radiator includes a first end 101a and a second end 101b disposed opposite the first end 101a, the first short-circuit point 103 can be located between the first end 101a and the feed point 102, and the second short-circuit point 104 can be located between the second end 101b and the feed point 102.

[0059] The component of the first radiation path described above, in addition to including the portion between the feed point and the first short-circuit point, can also include a portion of the first radiator between the first short-circuit point and the first end. As shown, Figure 2 As shown, in the first radiation path, the feed point 102 to the first end 101a can form a current mode 3; the first short-circuit point 103 to the first end 101a can form a current mode 4. The first radiator can radiate wireless signals of the first frequency band under the current mode 3 and the current mode 4.

[0060] It should be noted that the first impedance formed by the portion of the first radiator between the feed point and the first end and the portion between the first short-circuit point and the first end can be matched to a first preset impedance threshold. The first preset impedance threshold can be determined according to the impedance of the feed line connected to the feed point. For example, when the impedance on the feed line is 50 ohms, the first preset impedance threshold can also be set to 50 ohms. In this embodiment, by matching the first impedance to the first preset impedance threshold, the first radiation path can radiate the wireless signals of the first frequency band to the maximum extent, thereby improving the radiation efficiency of the first radiator under the current mode 3 and the current mode 4.

[0061] The component of the second radiation path described above, in addition to including the portion between the feed point and the second short-circuit point, can also include a portion of the first radiator between the second short-circuit point and the second end. As shown, Figure 3 As shown, in the second radiation path, the feed point 102 to the second end 101b can form a current mode 1; the second short-circuit point 104 to the second end 101b can form a current mode 2. The first radiator can radiate wireless signals of a second frequency band under the current mode 1 and the current mode 2. The frequency of the second frequency band is different from that of the first frequency band.

[0062] It should be noted that the second impedance formed by the portion of the first radiator between the feed point and the second end and the portion between the second short-circuit point and the second end can be matched to a second preset impedance threshold. The second preset impedance threshold can be determined according to the impedance of the feed line connected to the feed point. For example, when the impedance of the feed line is 50 ohms, the second preset impedance threshold can also be set to 50 ohms. In this embodiment, by matching the second impedance to the second preset impedance threshold, the second radiation path can radiate the wireless signals of the second frequency band to the maximum extent, thereby improving the radiation efficiency of the first radiator under the current mode 1 and the current mode 2.

[0063] Exemplarily, asFigure 4 As shown, the antenna module generally includes a third feeding point 201 and a grounding point 202, when the antenna module works in two frequency bands, the radiation paths in the antenna module are complex, and different radiation paths are not independent of each other, and thus the antenna module cannot be independently controlled to work in different frequency bands.

[0064] Based on this, the embodiment of the present disclosure proposes that the antenna module includes a feeding point, a first short-circuit point and a second short-circuit point; the first short-circuit point and the second short-circuit point are located on different sides of the feeding point. That is, the first short-circuit point and the second short-circuit point are different short-circuit points distributed on different sides of the feeding point, and the first radiation path formed by the first short-circuit point and the feeding point and the second radiation path formed by the second short-circuit point and the feeding point are independent paths, and there is no path intersection or overlap, and when the antenna module radiates wireless signals, different radiation paths can be independently controlled to radiate wireless signals of different frequencies, and the flexibility of the antenna module control is improved.

[0065] In some embodiments, as shown in the drawings, Figure 5 The antenna module further includes:

[0066] A second radiator 105 is arranged in a spaced manner with the first radiator 101 and is used to jointly radiate wireless signals with the first radiator 101 after coupling with the first radiator 101.

[0067] The above-mentioned second radiator can be coupled with the first radiator. When the first radiator radiates wireless signals, the second radiator can jointly transmit and receive wireless signals with the first radiator.

[0068] The above-mentioned first radiator includes a first radiation path and a second radiation path, the second radiator can be coupled with the first radiator corresponding to the first radiation path to jointly transmit and receive wireless signals, and can also be coupled with the first radiator corresponding to the second radiation path to jointly transmit and receive wireless signals, and the embodiment of the present disclosure does not make any limitation.

[0069] The coupling process of the above-mentioned second radiator and the first radiator includes: when the first radiator generates an alternating magnetic field under the excitation of the first electric signal output by the feeding point, the second radiator can generate an alternating current under the action of the alternating magnetic field, and can generate an alternating magnetic field based on the alternating current, and thus the second radiator can jointly transmit and receive wireless signals with the first radiator.

[0070] Compared with only using the first radiator to transmit and receive wireless signals, the embodiment of the present disclosure can not only increase the bandwidth of the antenna module for radiating wireless signals, but also increase the radiation area of the wireless signals, and thus the efficiency of transmitting and receiving wireless signals can be improved.

[0071] In some embodiments, as shown in the drawings, Figure 5As shown, the second radiator 105 has a first end 105a disposed close to the feed point and a second end 105b disposed away from the feed point;

[0072] The antenna module further comprises:

[0073] a third short-circuit point 106 at the second end 105b of the second radiator 105.

[0074] In the embodiments of the present disclosure, the second radiator can be disposed at the feed point, the first end of the second radiator is close to the feed point, and the second end of the second radiator is away from the feed point. That is, the distance between the first end of the second radiator and the feed point is less than the distance between the second end of the second radiator and the feed point.

[0075] The third short-circuit point is at the second end of the second radiator. The third short-circuit point is the ground point of the second radiator. As shown in the figure, Figure 6 As shown, when the second radiator 105 is coupled with the first radiator 101, the current coupled to the second radiator flows back to the second end 105b of the second radiator, and then flows back to the ground.

[0076] In the embodiments of the present disclosure, by disposing the third short-circuit point on the second radiator, the second radiator can form a coupling loop, and thus the second radiator can co-radiate wireless signals with the first radiator after coupling.

[0077] In some embodiments, the first radiation path occupies a ratio between the length of the first radiator and the length of the second radiator, and the ratio is within a ratio threshold range.

[0078] In the embodiments of the present disclosure, the ratio threshold can be set according to actual needs, for example, the ratio threshold can be set between 0.8 and 1.2, and the embodiments of the present disclosure are not limited.

[0079] When the second radiator is coupled with the first radiator corresponding to the first radiation path, since the frequency of the wireless signal radiated by the second radiator can be determined according to the length of the second radiator, by setting the ratio between the length of the second radiator and the length of the first radiator corresponding to the first radiation path within a ratio threshold range, the frequency radiated by the second radiator can be close to the frequency radiated by the first radiation path, and thus the frequency band of the wireless signal radiated by the first radiation path and the frequency band of the wireless signal radiated by the second radiator can be fused, and thus the frequency range can be expanded and the bandwidth of the wireless signal radiated by the first radiation path can be improved.

[0080] The second radiation path occupies a ratio between the length of the first radiator and the length of the second radiator when the second radiator is coupled with the first radiator corresponding to the second radiation path. The ratio can also be set within a threshold range. Thus, when the first radiator and the second radiator are coupled, the second radiator can radiate a frequency close to the frequency radiated by the second radiation path, and the frequency band of the wireless signal radiated by the first radiation path and the frequency band of the wireless signal radiated by the second radiator can be fused, thereby expanding the frequency range and improving the bandwidth of the wireless signal radiated by the second radiation path.

[0081] In some embodiments, the first radiator and the second radiator are located on the same plane.

[0082] In the embodiments of the present disclosure, the first radiator and the second radiator can be arranged on a middle frame of a terminal device having the antenna module, can also be arranged on a bezel of the terminal device, and can also be arranged on a back shell of the terminal device, which is not limited in the embodiments of the present disclosure.

[0083] In some embodiments, the first radiator is in a rectangular shape, and the second radiator is in an inverted L shape.

[0084] In some embodiments, the interval distance between the second radiator and the first radiator is within a range of 0.4 mm to 0.6 mm.

[0085] In the embodiments of the present disclosure, the interval distance between the second radiator and the first radiator is set within a range of 0.4 mm to 0.6 mm, which can achieve better coupling between the second radiator and the first radiator and improve the coupling efficiency of the coupling between the first radiator and the second radiator.

[0086] In some embodiments, the first radiation path occupies a length of the first radiator, and the length of the first radiation path is less than a length of the second radiation path occupying the first radiator.

[0087] The center frequency of the wireless signal radiated by the first radiation path is greater than the center frequency of the wireless signal radiated by the second radiation path.

[0088] In the embodiments of the present disclosure, the length of the first radiation path occupying the first radiator is less than the length of the second radiation path occupying the first radiator. Since the radiation frequency of the antenna module is determined according to the length of the radiator, and the radiation length is negatively related to the radiation frequency. Therefore, the center frequency of the wireless signal radiated by the first radiation path is greater than the center frequency of the wireless signal radiated by the second radiation path.

[0089] The center frequency of the wireless signal radiated by the first radiation path can be in the range of 5.1 GHz to 5.8 GHz; the center frequency of the wireless signal radiated by the second radiation path can be in the range of 2.4 GHz to 2.5 GHz, and this disclosure does not impose any limitations.

[0090] It should be noted that when the second radiator is coupled to the first radiator corresponding to the first radiation path, the bandwidth of the wireless signal radiated by the first radiation path of the antenna module is greater than the bandwidth of the wireless signal radiated by the second radiation path of the antenna module.

[0091] In some embodiments, the distance between the feed point and the short-circuit point is used to adjust the bandwidth of the antenna module.

[0092] In this embodiment, the distance between the feed point and the short-circuit point can be used to adjust the resonance depth of the antenna module. The resonance depth of the antenna module is negatively correlated with its bandwidth; therefore, the bandwidth of the antenna module can be adjusted by changing the distance between the feed point and the short-circuit point. For example, the bandwidth of the antenna module can be expanded or narrowed.

[0093] This disclosure also proposes a terminal device, such as... Figure 6 As shown, the terminal device includes:

[0094] Frame;

[0095] A printed circuit board is located within the accommodating space formed by the frame, and has a ground layer and a power supply link layer disposed at intervals from the ground layer;

[0096] The antenna module, as described in the first aspect above, is located on the surface of the frame facing the printed circuit board and is spaced apart from the printed circuit board.

[0097] The first connecting piece 303 connects the feed point 301 of the antenna module and the feed link layer;

[0098] The second connecting piece 304 connects the short-circuit point 302 of the antenna module to the ground layer.

[0099] like Figure 7 As shown, the antenna module also includes a second radiator, the third short-circuit point of which is connected to the ground plane through a third connecting piece 305.

The mobile terminals include mobile phones, laptops, or tablets, and the wearable electronic devices include smartwatches or smart bracelets.

[0101] In the embodiments of the present disclosure, based on the interval between the antenna module and the printed circuit board, the first connecting sheet can better realize the connection of the feed point and the feed link layer, and the second connecting sheet can better realize the connection of the short circuit point and the ground layer. In addition, the embodiments of the present disclosure propose that the antenna module includes a feed point, a first short circuit point and a second short circuit point; the first short circuit point and the second short circuit point are located on different sides of the feed point. That is, the first short circuit point and the second short circuit point are different short circuit points distributed on different sides of the feed point, and the first radiation path formed by the first short circuit point and the feed point and the second radiation path formed by the second short circuit point and the feed point are independent paths, and there is no path intersection or overlap, and when the antenna module radiates wireless signals, different radiation paths can be independently controlled to radiate wireless signals of different frequencies, thereby improving the flexibility of the antenna module control.

[0102] In some embodiments, the first connecting sheet and the second connecting sheet are both connecting elastic sheets.

[0103] In the embodiments of the present disclosure, the connecting elastic sheet can be elastically deformed, and when the terminal device collides due to falling of the terminal device, the connection between the antenna module and the printed circuit board is no longer a hard connection, but an elastic connection through the elastic deformation performance of the connecting elastic sheet, so that the connection between the antenna module and the printed circuit board is more reliable.

[0104] It should be noted that the "first" and "second" in the embodiments of the present disclosure are only for convenience of description and distinction, and have no other specific meaning.
