[0033] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0034] like Figure 1 and Figure 2 As shown, an embodiment of the present disclosure proposes an antenna module, including a radiator 1 and a transparent metal film 2, the radiator 1 is used to radiate electromagnetic wave signals, the transparent metal film 2 and the radiator 1 are arranged adjacent to each other, and the transparent metal film 2 is provided with a gap 3, the gap 3 is used to couple the transparent metal film 2 and the radiator 1 so that the transparent metal film 2 radiates electromagnetic wave signals.

[0035] It can be understood that since the transparent metal film 2 and the radiator 1 are arranged adjacent to each other and the transparent metal film 2 is provided with a gap 3, when the radiator 1 radiates an electromagnetic wave signal, the gap 3 not only facilitates the passage of the electromagnetic wave signal, thereby reducing the shielding and blocking of the electromagnetic wave signal by the transparent metal film 2, but also can adjust the impedance of the transparent metal film 2, so that the transparent metal film 2 can be efficiently coupled with the radiator 1, and then the transparent metal film 2 can utilize the radiator 1 to realize the radiation of electromagnetic wave signals.

[0036] Among them, through the setting of the gap 3, not only the radiation efficiency of the radiator 1 as the first scatterer in the antenna module is improved, but also the transparent metal film 2 is converted into the second scatterer of the antenna module to radiate electromagnetic wave signals, thereby effectively improving the radiation performance and efficiency of the antenna module, meeting the high-performance communication needs, and at the same time, the removal area of ​​the transparent metal film 2 is reduced, so that the transparent metal film 2 can utilize a smaller removal rate to stably realize the functions of heat insulation, UV protection, etc., thereby meeting the needs of high comfort.

[0037] It should be noted that when the transparent metal film 2 and the radiator 1 are arranged adjacent to each other, the matching of the radiator 1 will be affected due to the metal properties of the transparent metal film 2, which will also cause mismatch in the impedance matching of the antenna module. By setting the gap 3, the impedance matching of the antenna module can be improved, so that the antenna module has better omnidirectional radiation characteristics and also has a good impedance matching effect.

[0038] The light-transmitting metal film 2 refers to a film having light-transmitting properties and metallic properties. The specific type of the light-transmitting metal film 2 can be set according to actual needs and is not limited to this. For example, the light-transmitting metal film 2 can be a metal ion coating with silver ions as the main material.

[0039] The gap 3 is used to pass electromagnetic wave signals and adjust the impedance of the light-transmitting metal film 2. The specific type of the gap 3 can be set according to actual needs and is not limited to this.

[0040] The radiator 1 is used to radiate electromagnetic wave signals. The specific type of the radiator 1 can be set according to actual needs and is not limited to this. For example, the radiator 1 can be a vehicle-mounted antenna set in a vehicle.

[0041] like Figure 3 As shown, in some embodiments, the gap 3 includes a first gap 31 and a second gap 32, the length of the first gap 31 is half of the wavelength of the electromagnetic wave signal, and the length of the second gap 32 is half of the wavelength of the electromagnetic wave signal, wherein the first gap 31 and the second gap 32 intersect and form a preset angle.

[0042] It can be understood that since the length of the first slit 31 and the length of the second slit 32 are respectively half of the wavelength of the electromagnetic wave signal, and the first slit 31 and the second slit 32 intersect and form a preset angle, the first slit 31 and the second slit 32 utilize the length of half the wavelength and the intersecting layout structure. On the one hand, they can stably adjust the impedance of the transparent metal film 2, so that the impedance of the transparent metal film 2 and the electromagnetic wave signal are efficiently matched, thereby realizing the efficient radiation of the electromagnetic wave signal by the transparent metal film 2; on the other hand, it can facilitate the passage of the electromagnetic wave signal, thereby reducing the shielding and shielding of the radiator 1 by the transparent metal film 2, thereby realizing the efficient radiation of the electromagnetic wave signal by the radiator 1. Therefore, through the cooperation of the first slit 31 and the second slit 32, the high-performance communication requirements of the antenna module are met, and at the same time, the transparent metal film 2 has a smaller removal rate.

[0043] It should be noted that the first slit 31 and the second slit 32 are used to pass electromagnetic wave signals and adjust the impedance of the transparent metal film 2. The specific types of the first slit 31 and the second slit 32 can be set according to actual needs and are not limited to this. For example, the first slit 31 and the second slit 32 are equal in length and are in the shape of an "I" slit.

[0044] The length of the first slot 31 and the length of the second slot 32 are set according to the wavelength of the electromagnetic wave signal, and there is no limitation thereto.

[0045] The width of the first slit 31 and the width of the second slit 32 can be set according to actual needs and are not limited thereto.

[0046] The preset angle of the first slit 31 and the second slit 32 can be set according to actual needs, and there is no limitation to this. For example, the preset angle of the first slit 31 and the second slit 32 can be 90 degrees or other angles close to 90 degrees.

[0047] like Figure 3 As shown, in some embodiments, the first slit 31 and the second slit 32 are orthogonal.

[0048] It can be understood that since the first slot 31 and the second slot 32 are orthogonal, the electromagnetic wave signal can stably pass through the first slot 31 and the second slot 32 with polarization completeness, thereby ensuring high-quality propagation of the electromagnetic wave signal, thereby improving the radiation performance and efficiency of the antenna module and meeting high-performance communication requirements.

[0049] It should be noted that electromagnetic waves are oscillating particle waves derived and emitted in space by electric and magnetic fields that oscillate in phase and are perpendicular to each other. They are electromagnetic fields that propagate in the form of waves. Since electromagnetic waves are transverse waves and have the arbitrariness of propagation, when the gap 3 is the first gap 31 and the second gap 32 arranged orthogonally, the electromagnetic wave signal can pass stably and ensure the integrity of polarization.

[0050] Since the first slit 31 and the second slit 32 are orthogonal, the preset angle between the first slit 31 and the second slit 32 is 90 degrees, and Figure 3 It is also shown in the figure that the preset angle between the first gap 31 and the second gap 32 is 90 degrees.

[0051] like Figure 3 As shown, in some embodiments, the intersection of the first slit 31 and the second slit 32 is at half the length of the first slit 31 .

[0052] It can be understood that since the intersection of the first slot 31 and the second slot 32 is half the length of the first slot 31, when the radiator 1 radiates an electromagnetic wave signal, the electromagnetic wave signal can easily pass through the first slot 31, thereby ensuring the polarization completeness of the electromagnetic wave signal propagation, and further ensuring the high-quality propagation of the electromagnetic wave signal, thereby improving the radiation performance and efficiency of the antenna module.

[0053] like Figure 3 As shown, in some embodiments, the intersection of the first slit 31 and the second slit 32 is at half the length of the second slit 32 .

[0054] It can be understood that since the intersection of the first slot 31 and the second slot 32 is half the length of the second slot 32, when the radiator 1 radiates an electromagnetic wave signal, the electromagnetic wave signal can easily pass through the second slot 32, thereby ensuring the polarization completeness of the electromagnetic wave signal propagation, and further ensuring the high-quality propagation of the electromagnetic wave signal, thereby improving the radiation performance and efficiency of the antenna module.

[0055] It should be noted that since the intersection of the first gap 31 and the second gap 32 is at half the length of the first gap 31 and half the length of the second gap 32, and the first gap 31 and the second gap 32 are orthogonal, the first gap 31 and the second gap 32 form a "cross"-shaped gap 3, and the gap 3 is a symmetrical structure.

[0056] Among them, from Figure 3 It can be seen that half the length of the first slit 31 and the second slit 32 are both A, that is, the intersection of the first slit 31 and the second slit 32 is half the length of the first slit 31 and half the length of the second slit 32 .

[0057] like Figure 4 As shown, in some embodiments, the gap 3 also includes a third gap 33 and a fourth gap 34, the length of the third gap 33 is half of the wavelength of the electromagnetic wave signal, and the length of the fourth gap 34 is half of the wavelength of the electromagnetic wave signal, wherein the first gap 31, the second gap 32, the third gap 33 and the fourth gap 34 intersect, and the third gap 33 and the fourth gap 34 are at a preset angle.

[0058] It can be understood that since the length of the third slit 33 and the length of the fourth slit 34 are respectively half of the wavelength of the electromagnetic wave signal, and the third slit 33 and the fourth slit 34 intersect and are at a preset angle, the third slit 33 and the fourth slit 34 utilize the length of half the wavelength and the intersecting layout structure. On the one hand, they can stably adjust the impedance of the transparent metal film 2, so that the impedance of the transparent metal film 2 and the electromagnetic wave signal are efficiently matched, thereby achieving efficient radiation of the electromagnetic wave signal by the transparent metal film 2; on the other hand, it can facilitate the passage of the electromagnetic wave signal, thereby reducing the shielding and shielding of the radiator 1 by the transparent metal film 2, thereby achieving efficient radiation of the electromagnetic wave signal by the radiator 1. Therefore, through the cooperation of the first slit 31, the second slit 32, the third slit 33 and the fourth slit 34, the communication performance of the antenna module is improved, and at the same time, the transparent metal film 2 still has a small removal rate.

[0059] It should be noted that the third slit 33 and the fourth slit 34 are used to pass electromagnetic wave signals and adjust the impedance of the transparent metal film 2. The specific types of the third slit 33 and the fourth slit 34 can be set according to actual needs and are not limited to this. For example, the third slit 33 and the fourth slit 34 are equal in length and are in the shape of an "I" slit structure.

[0060] The length of the third slot 33 and the length of the fourth slot 34 are set according to the wavelength of the electromagnetic wave signal, and there is no limitation thereto.

[0061] The width of the third slit 33 and the width of the fourth slit 34 can be set according to actual needs and are not limited thereto.

[0062] The preset angles of the third slot 33 and the fourth slot 34 can be set according to actual needs, and there is no limitation to this. For example, the preset angles of the third slot 33 and the fourth slot 34 can be 90 degrees.

[0063] Since the first slit 31 , the second slit 32 , the third slit 33 and the fourth slit 34 intersect, the slit 3 forms a star-shaped structure, which has a higher electromagnetic wave signal passing rate and a smaller removal rate of the light-transmitting metal film 2 .

[0064] In some embodiments, the slit 3 is disposed close to the radiator 1 , and the slit 3 and the radiator 1 at least partially overlap along the thickness direction of the light-transmitting metal film 2 .

[0065] It can be understood that since the gap 3 is arranged close to the radiator 1, and the gap 3 and the radiator 1 at least partially overlap along the thickness direction of the transparent metal film 2, the electromagnetic wave signal radiated by the radiator 1 can directly propagate outward along the gap 3 on the transparent metal film 2, thereby reducing the loss in reflection and ensuring higher radiation performance and efficiency of the antenna module.

[0066] It should be noted that the gap 3 and the radiator 1 may partially overlap along the thickness direction of the light-transmitting metal film 2 , or may completely overlap along the thickness direction of the light-transmitting metal film 2 , and there is no limitation to this.

[0067] like Figure 5 As shown, in some embodiments, the antenna module further includes a glass plate 4 , the glass plate 4 and the radiator 1 are arranged adjacent to each other, and the light-transmitting metal film 2 is arranged on the glass plate 4 .

[0068] It can be understood that since the transparent metal film 2 is arranged on the glass plate 4, it not only realizes the bearing of the transparent metal film 2 and ensures the efficient radiation of electromagnetic wave signals by the transparent metal film 2, but also enables the transparent metal film 2 to stably realize functions such as heat insulation and UV protection, thereby meeting the needs of high comfort.

[0069] It should be noted that the glass plate 4 is used to pass light and carry the light-transmitting metal film 2. At the same time, the glass plate 4 can also efficiently pass electromagnetic wave signals to avoid affecting the radiation performance and efficiency of the antenna module. The specific type of the glass plate 4 can be set according to actual needs and is not limited to this. For example, the glass plate 4 can be a window of a vehicle, such as a front windshield, a rear windshield, a side window, a door window, etc. Among them, the light-transmitting metal film 2 can be set on the glass plate 4 using a coating process.

[0070] In some embodiments, the electromagnetic wave signal is at least one of a low frequency signal, a medium frequency signal, and a high frequency signal.

[0071] It is understandable that the electromagnetic wave signal can be a low frequency signal, an intermediate frequency signal or a high frequency signal, or a combination of a low frequency signal and an intermediate frequency signal, or a combination of a low frequency signal and a high frequency signal, or a combination of a low frequency signal, an intermediate frequency signal and a high frequency signal. Therefore, the antenna module can be applied to different frequency bands to meet different communication needs.

[0072] Based on the simulation of the antenna module of the related embodiment and the antenna module of this embodiment, the following is obtained: Figures 6 to 11 The simulation diagram shown.

[0073] in, Figure 6is the radiation pattern of the antenna module of the relevant embodiment, and the antenna module of the relevant embodiment only has a radiator 1, and no light-transmitting metal film 2 is provided. Figure 6 The darker the color, the greater the radiation energy. Figure 6 It can be seen that the radiation direction of the antenna module diverges in all directions, especially in the positive direction of the Z axis.

[0074] Figure 7 is a VSWR curve of the antenna module of the related embodiment, and the antenna module of the related embodiment only has a radiator 1, and no light-transmitting metal film 2 is provided. Figure 7 In the figure, the horizontal axis is the frequency band and the vertical axis is the standing wave ratio. Figure 7 It can be seen that the antenna module has a small standing wave ratio (below 3) in multiple frequency bands, which can meet different communication needs.

[0075] Figure 8 is a radiation pattern of the antenna module of the relevant embodiment, and the antenna module of the relevant embodiment has a radiator 1, and a transparent metal film 2 is arranged near the radiator 1. Figure 8 The darker the color, the greater the radiation energy. Figure 8 It can be seen from the figure that the radiation direction of the antenna module is affected by the shielding of the transparent metal film 2, resulting in the radiation direction mainly toward the negative direction of the Z axis.

[0076] Fig. 9 is a standing wave ratio curve diagram of the antenna module of the relevant embodiment, and the antenna module of the relevant embodiment has a radiator 1, and a transparent metal film 2 is arranged near the radiator 1. Fig. 9 In the figure, the horizontal axis is the frequency band and the vertical axis is the standing wave ratio. Fig. 9 It can be seen that the antenna module has a large standing wave ratio in many frequency bands (especially at low frequencies), and communication cannot be achieved.

[0077] It can be seen from this that the transparent metal film 2 has a greater shielding effect on the radiator 1, which seriously affects the radiation performance and efficiency of the antenna module.

[0078] Fig.10 is the radiation pattern of the antenna module of this embodiment, Fig.10 The darker the color, the greater the radiation energy. Fig.10 It can be seen from the figure that the radiation direction of the antenna module diverges in all directions, and is not only not affected by the transparent metal film 2, but also has greater radiation energy at the transparent metal film 2.

[0079] Fig.11 is a standing wave ratio curve diagram of the antenna module of this embodiment. Fig.11In the figure, the horizontal axis is the frequency band and the vertical axis is the standing wave ratio. Fig.11 It can be seen that the antenna module has a small standing wave ratio (below 3) in multiple frequency bands (especially at low frequencies), which can meet different communication needs.

[0080] It can be seen from this that the radiation performance and efficiency of the antenna module are effectively improved by setting the slot 3.

[0081] The disclosed embodiment also provides a vehicle, comprising an antenna module as disclosed in the disclosed embodiment.

[0082] It can be understood that since the transparent metal film 2 and the radiator 1 are arranged adjacent to each other and the transparent metal film 2 is provided with a gap 3, when the radiator 1 radiates an electromagnetic wave signal, the gap 3 not only facilitates the passage of the electromagnetic wave signal, thereby reducing the shielding and blocking of the electromagnetic wave signal by the transparent metal film 2, but also can adjust the impedance of the transparent metal film 2, so that the transparent metal film 2 can be efficiently coupled with the radiator 1, and then the transparent metal film 2 can utilize the radiator 1 to realize the radiation of electromagnetic wave signals.

[0083] Among them, through the setting of the gap 3, not only the radiation efficiency of the radiator 1 as the first scatterer in the antenna module is improved, but also the transparent metal film 2 is converted into the second scatterer of the antenna module to radiate electromagnetic wave signals, thereby effectively improving the radiation performance and efficiency of the antenna module, meeting the high-performance communication needs of the vehicle, and at the same time, reducing the removal area of ​​the transparent metal film 2, so that the transparent metal film 2 can utilize a smaller removal rate to stably realize the functions of heat insulation, UV protection, etc., thereby meeting the high comfort requirements of the vehicle.

[0084] It should be noted that the specific type of vehicle can be set according to actual needs and is not limited to this. For example, the vehicle can be a fuel vehicle, an electric vehicle, etc.
