[0042] The following describes in detail embodiments of the present disclosure, 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 intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0043] like Figure 1 、 Figure 2、 Figure 3 and Figure 4 As shown, an embodiment of the present disclosure proposes an antenna module, comprising: an insulating shell 1, a patch antenna 2 and a first pattern antenna 3; wherein, the patch antenna 2 is arranged in the insulating shell 1 along the plane direction of the insulating shell 1, and the patch antenna 2 radiates a first signal along the thickness direction of the insulating shell 1, the first pattern antenna 3 is arranged in the insulating shell 1 along the thickness direction of the insulating shell 1, and the first pattern antenna 3 radiates a second signal along the thickness direction of the insulating shell 1, and the patch antenna 2 and the first pattern antenna 3 are spaced apart along the first direction in the plane direction of the insulating shell 1.

[0044] It can be understood that since the patch antenna 2 is arranged in the insulating shell 1 along the planar direction of the insulating shell 1, and the patch antenna 2 radiates the first signal along the thickness direction of the insulating shell 1, the antenna module can realize the radiation of the first signal in the thickness direction of the insulating shell 1, and can use the first signal to achieve communication; since the first pattern antenna 3 is arranged in the insulating shell 1 along the thickness direction of the insulating shell 1, and the first pattern antenna 3 radiates the second signal along the thickness direction of the insulating shell 1, the antenna module can realize the radiation of the second signal in the thickness direction of the insulating shell 1, and can use the second signal to achieve communication.

[0045] Therefore, the cooperation of the patch antenna 2 and the first pattern antenna 3 meets the different communication requirements of the antenna module. At the same time, since the patch antenna 2 radiates the first signal along its thickness direction and the first pattern antenna 3 radiates the second signal along its plane direction, the patch antenna 2 is arranged along the plane direction of the insulating shell 1, and the first pattern antenna 3 is arranged along the thickness direction of the insulating shell 1. This not only realizes the common aperture of the patch antenna 2 and the first pattern antenna 3, but also makes full use of the extreme space in the insulating shell 1 while ensuring a larger distance between the patch antenna 2 and the first pattern antenna 3, thereby effectively improving the isolation between the patch antenna 2 and the first pattern antenna 3, reducing the mutual influence between the patch antenna 2 and the first pattern antenna 3, and thus ensuring the higher communication performance of the antenna module.

[0046] It should be noted that the insulating housing 1 is made of insulating material and has a cavity therein for accommodating components such as the patch antenna 2 and the first pattern antenna 3. The specific type of the insulating housing 1 can be set according to actual needs and is not limited thereto. For example, the insulating housing 1 is made of plastic, wherein the planar direction of the insulating housing 1 is the direction of its length and width, and the thickness direction of the insulating housing 1 is the direction of its height. In other words, the patch antenna 2 is located in the length-width plane of the insulating housing 1, and the first pattern antenna 3 is located in the length-height plane or the width-height plane of the insulating housing 1. Furthermore, the first direction can be the width direction of the insulating housing 1, and the first pattern antenna 3 is located in the length-height plane of the insulating housing 1. The length of the insulating housing 1 can be 90 mm, 95 mm, 96 mm, 100 mm, etc., the width of the insulating housing 1 can be 70 mm, 74 mm, 75 mm, 79 mm, etc., and the height of the insulating housing 1 can be 20 mm, 24 mm, 25 mm, 28 mm, etc.

[0047] Patch antenna 2 is a pancake-shaped directional antenna. Patch antenna 2 may also be referred to as a panel, flat panel, or microstrip antenna. Patch antenna 2 has strong side-firing circular polarization performance. In this embodiment, patch antenna 2 is used to radiate the first signal. The specific type of patch antenna 2 can be set according to actual needs and is not limited thereto. The dimensions of patch antenna 2 are smaller than those of insulating housing 1. Specifically, the length of patch antenna 2 is smaller than the length of insulating housing 1, and the width of patch antenna 2 is smaller than the width of insulating housing 1.

[0048] The first pattern antenna 3 is a pattern antenna. A pattern antenna is an antenna that uses a metal pattern as a radiator. In this embodiment, the first pattern antenna 3 is used to radiate the second signal. The specific type of the first pattern antenna 3 can be set according to actual needs and is not limited to this. For example, the first pattern antenna 3 can be an FPC (Flexible Printed Circuit) antenna, an LCP (Liquid Crystal Polyester), an LDS (Laser-Direct-structuring) antenna, etc.

[0049] The size of the first pattern antenna 3 is smaller than that of the insulating shell 1 . Specifically, the length of the first pattern antenna 3 is smaller than that of the insulating shell 1 , and the width of the first pattern antenna 3 is smaller than the height of the insulating shell 1 .

[0050] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments, the antenna module also includes: a second pattern antenna 4, the second pattern antenna 4 is arranged in the insulating shell 1 along the thickness direction of the insulating shell 1, and the second pattern antenna 4 radiates a third signal along the thickness direction of the insulating shell 1, and the patch antenna 2 and the second pattern antenna 4 are spaced apart along the second direction in the plane direction of the insulating shell 1.

[0051] It can be understood that since the second pattern antenna 4 is arranged inside the insulating shell 1 along the thickness direction of the insulating shell 1, and the second pattern antenna 4 radiates the third signal along the thickness direction of the insulating shell 1, the antenna module can realize the radiation of the third signal in the thickness direction of the insulating shell 1, and can use the third signal to realize communication.

[0052] At the same time, since the second pattern antenna 4 radiates the third signal along its planar direction, the patch antenna 2 is arranged along the planar direction of the insulating shell 1, and the second pattern antenna 4 is arranged along the thickness direction of the insulating shell 1, not only can the common aperture of the patch antenna 2 and the second pattern antenna 4 be achieved, but also while fully utilizing the extreme space in the insulating shell 1, a larger distance is provided between the patch antenna 2 and the second pattern antenna 4, thereby effectively improving the isolation between the patch antenna 2 and the second pattern antenna 4, reducing the mutual influence between the patch antenna 2 and the second pattern antenna 4, and thus ensuring the higher communication performance of the antenna module.

[0053] Moreover, since the patch antenna 2 and the first pattern antenna 3 are spaced apart along the first direction, and the patch antenna 2 and the second pattern antenna 4 are spaced apart along the second direction, the first pattern antenna 3 and the second pattern antenna 4 can be respectively arranged at different positions of the insulating shell 1, thereby effectively improving the isolation between the first pattern antenna 3 and the second pattern antenna 4, reducing the mutual influence between the first pattern antenna 3 and the second pattern antenna 4, and thus ensuring the higher communication performance of the antenna module.

[0054] It should be noted that the second pattern antenna 4 is a pattern antenna. In this embodiment, the second pattern antenna 4 is used to radiate the third signal. The specific type of the second pattern antenna 4 can be set according to actual needs and is not limited to this. For example, the second pattern antenna 4 can be an FPC antenna, an LCP antenna, etc.

[0055] The second direction may be the length direction of the insulating housing 1. Specifically, the second pattern antenna 4 is located within the width-height plane of the insulating housing 1. That is, the first pattern antenna 3 and the second pattern antenna 4 are adjacently arranged in the circumferential direction of the insulating housing 1. The size of the second pattern antenna 4 is smaller than that of the insulating housing 1. Specifically, the length of the second pattern antenna 4 is smaller than the width of the insulating housing 1, and the width of the second pattern antenna 4 is smaller than the height of the insulating housing 1.

[0056] like Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the antenna module also includes: a circuit board 5, the circuit board 5 and the patch antenna 2 are spaced apart along the thickness direction of the insulating shell 1, and the feeding end of the circuit board 5 is respectively connected to the feeding point of the patch antenna 2, the feeding point of the first pattern antenna 3 and the feeding point of the second pattern antenna 4, and the grounding end of the circuit board 5 is respectively connected to the grounding point of the first pattern antenna 3 and the grounding point of the second pattern antenna 4.

[0057] It can be understood that since the feeding end of the circuit board 5 is respectively connected to the feeding point of the patch antenna 2, the feeding point of the first pattern antenna 3 and the feeding point of the second pattern antenna 4, and the grounding end of the circuit board 5 is respectively connected to the grounding point of the first pattern antenna 3 and the grounding point of the second pattern antenna 4, the circuit board 5 can send feeding signals to the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4 respectively, and make the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4 resonate with corresponding radiation currents, thereby realizing efficient radiation of the first signal, the second signal and the third signal by the antenna module.

[0058] At the same time, since the circuit board 5 and the patch antenna 2 are spaced apart along the thickness direction of the insulating shell 1, not only can the circuit board 5 make full use of the space in the plane direction of the insulating shell 1 to achieve a reasonable layout of the ultimate space, but also the distance between the circuit board 5 and the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4 is smaller, thereby facilitating the electrical connection between the circuit board 5 and the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4, ensuring the stable operation of the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4.

[0059] It should be noted that the circuit board 5 is used for signal transmission and processing. The specific type of the circuit board 5 can be set according to actual needs and is not limited to this. For example, the circuit board 5 includes printed metal for signal transmission and a chip for signal processing. The size of the circuit board 5 can be close to that of the patch antenna 2.

[0060] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the antenna module further includes: a power supply component 6, the power supply end of the power supply component 6 is connected to the power supply end of the circuit board 5; wherein, the power supply component 6 is arranged in the insulating shell 1 along the first direction, and the power supply component 6 and the patch antenna 2 are spaced apart along the second direction, and the power supply component 6 is located at the end of the patch antenna 2 away from the second pattern antenna 4.

[0061] It can be understood that since the power supply end of the power supply component 6 is connected to the power supply end of the circuit board 5, the power supply component 6 can supply power to the circuit board 5, thereby ensuring the stable operation of the circuit board 5, and further ensuring the efficient radiation of the first signal, the second signal and the third signal by the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4 respectively.

[0062] At the same time, since the power supply component 6 is arranged in the insulating shell 1 along the first direction, and the power supply component 6 and the patch antenna 2 are spaced apart along the second direction, the power supply component 6 is located at the end of the patch antenna 2 away from the second pattern antenna 4, which not only can reduce the space occupied by the power supply component 6 in the thickness direction of the insulating shell 1 and realize a reasonable layout in the extreme space, but also can avoid the power supply component 6 and the circuit board 5, patch antenna 2, first pattern antenna 3 and second pattern antenna 4 in the thickness direction of the insulating shell 1. The overlap can be avoided, thereby reducing the influence of the heat of the power supply component 6 on the radiation performance of the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4.

[0063] It should be noted that the power supply assembly 6 is used to power the circuit board 5. The specific type of power supply assembly 6 can be set according to actual needs and is not limited to this. For example, the power supply assembly 6 includes a nearly cylindrical battery and wires connecting the battery and the circuit board 5. The circuit board 5 may also be provided with circuits and chips for managing the power supply assembly 6. Because the power supply assembly 6 needs to store and convert electrical energy, it tends to generate considerable heat during operation. Excessive temperatures can reduce the operating speed of components such as the circuit board 5, the patch antenna 2, the first pattern antenna 3, and the second pattern antenna 4, and can also damage these components. Therefore, locating the power supply assembly 6 away from these components can ensure stable operation of the antenna module.

[0064] like Figure 1 and Figure 3 As shown, in some embodiments, the antenna module further includes: an interactive component 7, the output end of the interactive component 7 is connected to the input end of the circuit board 5, and the input end of the interactive component 7 is connected to the output end of the circuit board 5; wherein, the non-metallic portion of the interactive component 7 accounts for a greater proportion than a set proportion, the interactive component 7 is connected to the patch antenna 2 along a first direction, and the interactive component 7 extends outside the insulating shell 1, and the interactive component 7 and the first pattern antenna 3 are located at the same end of the patch antenna 2.

[0065] It can be understood that since the output end of the interactive component 7 is connected to the input end of the circuit board 5, and the input end of the interactive component 7 is connected to the output end of the circuit board 5, the circuit board 5 can use the interactive component 7 to realize the input and output of instructions, thereby facilitating the human-computer interaction of the antenna module and meeting different functional requirements.

[0066] At the same time, because the interactive component 7 and the patch antenna 2 are connected along the first direction and extend outside the insulating housing 1, the interactive component 7 and the first pattern antenna 3 are located at the same end of the patch antenna 2, allowing the interactive component 7 to be arranged close to the first pattern antenna 3. Moreover, because the non-metallic portion of the interactive component 7 accounts for a larger proportion than the set ratio, the interactive component 7, which is mainly composed of non-metallic materials, has a smaller impact on the first pattern antenna 3. As a result, not only can the interactive component 7 fully utilize the space at the first pattern antenna 3 in the insulating housing 1, achieving a reasonable layout with the ultimate space, but it can also ensure that the first pattern antenna 3 radiates the second signal efficiently, thereby ensuring high performance of the antenna module.

[0067] It should be noted that the interactive component 7 is used for command input and output of the circuit board 5 to realize human-computer interaction of the antenna module. The specific type of the interactive component 7 can be set according to actual needs and is not limited to this. For example, the interactive component 7 can be a button 702, a speaker, an indicator light 701, a microphone, a display, etc.

[0068] The non-metallic portion of interactive component 7 refers to a portion made of a non-metallic material. If the non-metallic portion of interactive component 7 accounts for a greater than a set ratio, that is, the majority of interactive component 7 is made of a non-metallic material, which has a minimal impact on antenna radiation. The set ratio can be set based on actual needs and is not limited thereto.

[0069] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the patch antenna 2 includes: a radiator 201 and a dielectric plate 202; wherein the dielectric plate 202 is arranged in the insulating shell 1 along the plane direction of the insulating shell 1, and the radiator 201, the dielectric plate 202 and the circuit board 5 are stacked along the thickness direction of the insulating shell 1, the radiator 201 and the first pattern antenna 3 are spaced apart along the first direction, the radiator 201 and the second pattern antenna 4 are spaced apart along the second direction, the feeding point of the radiator 201 is connected to the feeding end of the circuit board 5, and the radiator 201 radiates the first signal along the thickness direction of the insulating shell 1, the interactive component 7 and the dielectric plate 202 are connected along the first direction, and the interactive component 7 and the first pattern antenna 3 are located at the same end of the dielectric plate 202.

[0070] It can be understood that since the dielectric plate 202 is arranged inside the insulating shell 1 along the planar direction of the insulating shell 1, and the radiator 201 and the dielectric plate 202 are stacked along the thickness direction of the insulating shell 1, the feeding point of the radiator 201 is connected to the feeding end of the circuit board 5, so that the antenna module can realize the radiation of the first signal in the thickness direction of the insulating shell 1, and can use the first signal to realize communication.

[0071] At the same time, since the radiator 201 radiates the first signal along its thickness direction, and the first pattern antenna 3 radiates the second signal along its plane direction, and the second pattern antenna 4 radiates the second signal along its plane direction, the radiator 201 is arranged along the plane direction of the insulating shell 1, and the first pattern antenna 3 is arranged along the thickness direction of the insulating shell 1, and the second pattern antenna 4 is arranged along the thickness direction of the insulating shell 1, not only can the common aperture of the radiator 201, the first pattern antenna 3 and the second pattern antenna 4 be achieved, but also while fully utilizing the extreme space in the insulating shell 1, a larger spacing is provided between the radiator 201, the first pattern antenna 3 and the second pattern antenna 4, thereby effectively improving the isolation between the radiator 201, the first pattern antenna 3 and the second pattern antenna 4, reducing the mutual influence between the radiator 201, the first pattern antenna 3 and the second pattern antenna 4, and thus ensuring the higher communication performance of the antenna module.

[0072] Since the interactive component 7 and the dielectric plate 202 are connected along the first direction, and the interactive component 7 and the first pattern antenna 3 are located at the same end of the dielectric plate 202, the interactive component 7 can reuse the dielectric plate 202 of the patch antenna 2, thereby reducing the space occupied by the interactive component 7 and achieving a reasonable layout of the ultimate space in the insulating shell 1.

[0073] It should be noted that the radiator 201 is used to generate a resonant current under the excitation of the circuit board 5 to realize the radiation of the first signal. The specific type of the radiator 201 can be set according to actual needs and is not limited to this. For example, the radiator 201 may include a plurality of metal patches arranged at intervals along the thickness direction of the insulating shell 1. At the same time, the patch antenna 2 also includes a dielectric arranged between adjacent metal patches, a feeding probe for feeding the metal patches, and other components.

[0074] The dielectric plate 202 is used to support the radiator 201 and the interactive component 7. The specific type of dielectric plate 202 can be set according to actual needs and is not limited thereto. In addition to the interactive component 7, the signal transmission lines between the interactive component 7 and the circuit board 5, at least part of the control circuit, etc. can also be arranged on the dielectric plate 202.

[0075] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the patch antenna 2 further includes: a metal plate 203, which is arranged on the dielectric plate 202, and the metal plate 203 is connected to the grounding point of the circuit board 5, and the metal plate 203 enables the radiator 201 to radiate the first signal along the direction from the dielectric plate 202 to the radiator 201.

[0076] It can be understood that since the metal plate 203 is arranged on the dielectric plate 202, and the radiator 201, the dielectric plate 202 and the circuit board 5 are stacked along the thickness direction of the insulating shell 1, the metal plate 203 can play a reflective role when the radiator 201 radiates the first signal, thereby realizing the directional radiation of the patch antenna 2, and thus ensuring the high-performance communication of the antenna module.

[0077] Since the metal plate 203 is connected to the grounding point of the circuit board 5, the circuit board 5 can reuse the metal plate 203 of the patch antenna 2 to achieve grounding, thereby reducing the space occupied by the circuit board 5 and achieving a reasonable layout of the ultimate space in the insulating shell 1.

[0078] It should be noted that the metal plate 203 is used to reflect the first signal from the radiator 201 to achieve stable pointing of the patch antenna 2. The specific type of the metal plate 203 can be set according to actual needs and is not limited to this. For example, the metal plate 203 can be a metal layer such as copper foil. The metal plate 203 can be disposed on the side of the dielectric plate 202 close to the radiator 201 and / or on the side of the dielectric plate 202 close to the circuit board 5. When the metal plate 203 is disposed on both sides of the dielectric plate 202, the two sides can be electrically connected via metal vias.

[0079] The side surface of the insulating housing 1 close to the radiator 201 may be its top surface, and the side surface of the insulating housing 1 close to the circuit board 5 may be its bottom surface.

[0080] like Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the antenna module further includes: a cable 8 and / or a grounding pin 9, the cable 8 is arranged at the third feeding end of the circuit board 5, and the end of the cable 8 away from the circuit board 5 is connected to the feeding point of the radiator 201, the grounding pin 9 is arranged on the grounding point of the circuit board 5, and the end of the grounding pin 9 away from the circuit board 5 is connected to the metal plate 203.

[0081] It can be understood that since the cable 8 is arranged at the third feeding end of the circuit board 5, and the end of the cable 8 away from the circuit board 5 is connected to the feeding point of the radiator 201, the third feeding end of the circuit board 5 can use the cable 8 to feed the excitation signal to the feeding point of the radiator 201, thereby ensuring that the radiator 201 can generate a resonant current and stably radiate the first signal.

[0082] Since the grounding pin 9 is arranged on the grounding point of the circuit board 5, and the end of the grounding pin 9 away from the circuit board 5 is connected to the metal plate 203, the grounding point of the circuit board 5 can be electrically connected to the metal plate 203 using the grounding pin 9, thereby ensuring stable grounding of the circuit board 5.

[0083] It should be noted that the cable 8 is used for electrical connection between the circuit board 5 and the radiator 201 . The specific type of the cable 8 can be set according to actual needs and is not limited to this. For example, the cable 8 can be a coaxial cable.

[0084] The third feeding terminal of the circuit board 5 can be set on the side of the circuit board 5 away from the patch antenna 2. One end of the cable 8 is set at the third feeding terminal of the circuit board 5. The end of the cable 8 away from the circuit board 5 passes around the circuit board 5 and is connected to the feeding probe in the patch antenna 2. The feeding probe is connected to the feeding point of the radiator 201 and passes through the dielectric plate 202 and the metal plate 203.

[0085] The grounding pin 9 is used for electrical connection between the circuit board 5 and the metal plate 203 . The specific type of the grounding pin 9 can be set according to actual needs and is not limited thereto.

[0086] like Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the interactive component 7 includes: at least one indicator light 701 and / or at least one button 702, the input end of the indicator light 701 is connected to the output end of the circuit board 5, and the indicator light 701 and the dielectric board 202 are connected along a first direction, the indicator light 701 and the first pattern antenna 3 are located at the same end of the dielectric board 202, the first pattern antenna 3 is provided with an avoidance hole, the indicator light 701 passes through the avoidance hole and extends to the outside of the insulating shell 1, the output end of the button 702 is connected to the input end of the circuit board 5, and the button 702 and the dielectric board 202 are connected along the first direction, the button 702 extends to the outside of the insulating shell 1, and the button 702 and the first pattern antenna 3 are located at the same end of the dielectric board 202.

[0087] It is understandable that since the input end of the indicator light 701 is connected to the output end of the circuit board 5, the circuit board 5 can use the indicator light 701 to emit light information, thereby facilitating human-computer interaction of the antenna module and meeting different functional requirements.

[0088] At the same time, since the indicator light 701 and the dielectric plate 202 are connected along the first direction, and the indicator light 701 and the first pattern antenna 3 are located at the same end of the dielectric plate 202, the first pattern antenna 3 is provided with an avoidance hole, and the indicator light 701 passes through the avoidance hole and extends outside the insulating shell 1, so that the indicator light 701 and the first pattern antenna 3 can be compactly arranged, which not only enables the indicator light 701 to make full use of the space at the first pattern antenna 3 in the insulating shell 1 to achieve a reasonable layout of the extreme space, but also ensures the efficient radiation of the second signal by the first pattern antenna 3, thereby ensuring the higher performance of the antenna module.

[0089] Since the output end of the button 702 is connected to the input end of the circuit board 5, the circuit board 5 can receive external instructions via the button 702, thereby facilitating human-computer interaction of the antenna module and meeting different functional requirements.

[0090] At the same time, the output end of the button 702 is connected to the input end of the circuit board 5, and the button 702 is connected to the dielectric plate 202 along the first direction. The button 702 extends outside the insulating shell 1, and the button 702 and the first pattern antenna 3 are located at the same end of the dielectric plate 202, so that the button 702 can be arranged close to the first pattern antenna 3. This not only enables the button 702 to make full use of the space at the first pattern antenna 3 in the insulating shell 1 to achieve a reasonable layout of the extreme space, but also ensures the efficient radiation of the second signal by the first pattern antenna 3, thereby ensuring the higher performance of the antenna module.

[0091] It should be noted that indicator light 701 is used to emit light information. The specific type of indicator light 701 can be set according to actual needs and is not limited to this. Among them, the main part of indicator light 701 is non-metallic material, that is, the non-metallic part of indicator light 701 accounts for more than a set proportion. Therefore, indicator light 701 has a minimal impact on the performance of first pattern antenna 3.

[0092] Key 702 is used to input external commands. The specific type of key 702 can be set according to actual needs and is not limited to this. The main portion of key 702 is non-metallic material, that is, the non-metallic portion of key 702 accounts for a larger than set proportion. Therefore, key 702 has minimal impact on the performance of first pattern antenna 3.

[0093] Among them, the dielectric plate 202 can be a nearly rectangular plate structure. When two buttons 702 are set, one button 702 is set on the main part of the dielectric plate 202, and the other button 702 is set on the ear plate extending from one end of the dielectric plate 202 close to the second pattern antenna 4.

[0094] Since the indicator light 701 and the button 702 both extend outside the insulating shell 1, the structure of the insulating shell 1 needs to adapt to the indicator light 701 and the button 702. Specifically, an opening can be provided on the insulating shell 1, and a transparent or translucent cover plate is provided on the opening. The indicator light 701 is located in the opening, and the cover plate is used to achieve protection and lighting; an elastic plate is provided on the insulating shell 1, and the elastic plate and the button 702 are in contact. The elastic plate can be used to protect the button 702 while ensuring the normal operation of the button 702.

[0096] It can be understood that since the first communication pin 10 is arranged on the output end of the circuit board 5, and the end of the first communication pin 10 away from the circuit board 5 is connected to the input end of the indicator light 701, the circuit board 5 can use the first communication pin 10 to send a control signal to the indicator light 701, thereby facilitating the use of the indicator light 701 to achieve human-computer interaction, thereby meeting different functional requirements.

[0097] Since the second communication pin 11 is arranged on the input end of the circuit board 5, and the end of the second communication pin 11 away from the circuit board 5 is connected to the output end of the button 702, the circuit board 5 can use the second communication pin 11 to receive the control signal of the button 702, thereby facilitating the use of the button 702 to achieve human-computer interaction, thereby meeting different functional requirements.

[0098] It should be noted that the first communication pin header 10 is used to electrically connect the circuit board 5 and the indicator light 701. The specific type of the first communication pin header 10 can be set according to actual needs and is not limited thereto. The end of the first communication pin header 10 away from the circuit board 5 is connected to the indicator light 701 via a printed circuit on the dielectric board 202.

[0099] The second communication pin header 11 is used for electrical connection between the circuit board 5 and the button 702.

The end of the second communication pin header 11 away from the circuit board 5 is connected to the button 702 via the printed circuit board 202.

[0100] The grounding pin header 9 , the first communication pin header 10 and the second communication pin header 11 are all needle-shaped metals. The grounding pin header 9 , the first communication pin header 10 and the second communication pin header 11 can be centrally arranged in a certain area of ​​the circuit board 5 .

[0101] like Figure 1 and Figure 3 As shown, in some embodiments, the antenna module also includes: an interface component 12, the output end of the interface component 12 is connected to the input end of the circuit board 5, and the input end of the interface component 12 is connected to the output end of the circuit board 5; wherein, the interface component 12 and the circuit board 5 are connected along a first direction, and the interface component 12 extends outside the insulating shell 1, and the interface component 12 is located at an end of the circuit board 5 away from the first pattern antenna 3.

[0102] It can be understood that since the output end of the interface component 12 is connected to the input end of the circuit board 5, and the input end of the interface component 12 is connected to the output end of the circuit board 5, the circuit board 5 can use the interface component 12 to achieve device connection, thereby facilitating the realization of different functions of the antenna module and thus meeting usage requirements.

[0103] At the same time, since the interface component 12 and the circuit board 5 are connected along the first direction and the interface component 12 extends outside the insulating shell 1, the interface component 12 is located at the end of the circuit board 5 away from the first pattern antenna 3, so that the interface component 12 can fully utilize the extreme space in the insulating shell 1 while having a large distance between the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4, thereby reducing the impact of the interface component 12 on the performance of the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4, and ensuring a higher radiation efficiency of the antenna module.

[0104] It should be noted that the interface component 12 is used to connect the circuit board 5 to external devices. The specific type of interface component 12 can be set according to actual needs and is not limited to this. For example, the interface component 12 can be a card slot 121, a data interface 122, etc. Compared with the interactive component 7, the interface component 12 requires more metal parts such as gold fingers, which has a greater impact on the antenna's radiation performance. Based on this, based on this, placing the interface component 12 as far as possible from the patch antenna 2, the first pattern antenna 3, and the second pattern antenna 4 can ensure that the antenna module has high communication performance while realizing the interface function.

[0105] like Figure 4 and Figure 5 As shown, in some embodiments, the interface component 12 includes: at least one card slot 121 and / or at least one data interface 122, the output end of the card slot 121 is connected to the input end of the circuit board 5, the input end of the card slot 121 is connected to the output end of the circuit board 5, the card slot 121 and the circuit board 5 are connected along a first direction, and the card slot 121 extends outside the insulating shell 1, the card slot 121 is located at the end of the circuit board 5 away from the first pattern antenna 3, the output end of the data interface 122 is connected to the input end of the circuit board 5, the input end of the data interface 122 is connected to the output end of the circuit board 5, the data interface 122 and the circuit board 5 are connected along the first direction, and the data interface 122 extends outside the insulating shell 1, and the data interface 122 is located at the end of the circuit board 5 away from the first pattern antenna 3.

[0106] It can be understood that since the output end of the card slot 121 is connected to the input end of the circuit board 5, and the input end of the card slot 121 is connected to the output end of the circuit board 5, the circuit board 5 can use the card slot 121 to realize the connection of the functional card, thereby facilitating the realization of different functions of the antenna module and thus meeting the usage requirements.

[0107] At the same time, since the card slot 121 and the circuit board 5 are connected along the first direction and the card slot 121 extends outside the insulating shell 1, the card slot 121 is located at the end of the circuit board 5 away from the first pattern antenna 3, so that the card slot 121 can fully utilize the extreme space in the insulating shell 1 while having a large distance between the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4, thereby reducing the impact of the card slot 121 on the performance of the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4, and ensuring a high radiation efficiency of the antenna module.

[0108] Since the output end of the data interface 122 is connected to the input end of the circuit board 5, and the input end of the data interface 122 is connected to the output end of the circuit board 5, the circuit board 5 can use the data interface 122 to realize the connection of functional components, thereby facilitating the realization of different functions of the antenna module and thus meeting usage requirements.

[0109] At the same time, since the data interface 122 and the circuit board 5 are connected along the first direction and the data interface 122 extends outside the insulating shell 1, the data interface 122 is located at the end of the circuit board 5 away from the first pattern antenna 3, so that the data interface 122 can fully utilize the extreme space in the insulating shell 1 while having a large distance between the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4, thereby reducing the impact of the data interface 122 on the performance of the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4, and ensuring a high radiation efficiency of the antenna module.

[0110] It should be noted that the card slot 121 is used to connect the circuit board 5 and the external function card. The specific type of the card slot 121 can be set according to actual needs and is not limited to this. For example, the card slot 121 can be used to insert a SIM (Subscriber Identity Module) card.

[0111] The data interface 122 is used to connect the circuit board 5 and external functional devices. The specific type of the data interface 122 can be set according to actual needs and is not limited to this. For example, the data interface 122 can be a USB (Universal Serial Bus) interface.

[0112] Among them, since the card slot 121 and the data interface 122 both extend outside the insulating shell 1, the structure of the insulating shell 1 needs to adapt to the card slot 121 and the data interface 122. Specifically, two bar holes can be provided on the insulating shell 1, and the card slot 121 and the data interface 122 are respectively located in the two bar holes. When the function card is inserted into the card slot 121, its outer surface can be flush with the outer surface of the insulating shell 1.

[0113] like Figure 2As shown, in some embodiments, the antenna module further includes: a first feeding spring 13 and / or a first grounding spring 14, the first feeding spring 13 is arranged at the first feeding end of the circuit board 5, and the first feeding spring 13 and the feeding point of the first pattern antenna 3 are abutted, and the first grounding spring 14 is arranged at the first grounding end of the circuit board 5, and the first grounding spring 14 and the grounding point of the first pattern antenna 3 are abutted.

[0114] It can be understood that because the first feeding spring 13 is provided at the first feeding end of the circuit board 5 and the first feeding spring 13 abuts the feeding point of the first pattern antenna 3, the first feeding end of the circuit board 5 can use the first feeding spring 13 to feed the excitation signal to the feeding point of the first pattern antenna 3; and because the first grounding spring 14 is provided at the first grounding end of the circuit board 5 and the first grounding spring 14 abuts the grounding point of the first pattern antenna 3, the first grounding end of the circuit board 5 can use the first grounding spring 14 to receive the ground return signal from the grounding point of the first pattern antenna 3. Thus, through the cooperation of the first feeding spring 13 and the first grounding spring 14, it is ensured that the first pattern antenna 3 can generate a resonant current and stably radiate the second signal.

[0115] It should be noted that the first feeding spring 13 is used for electrical connection between the first feeding end of the circuit board 5 and the feeding point of the first pattern antenna 3. The specific type of the first feeding spring 13 can be set according to actual needs and is not limited to this.

[0116] The first grounding spring 14 is used for electrical connection between the first grounding end of the circuit board 5 and the grounding point of the first pattern antenna 3 . The specific type of the first grounding spring 14 can be set according to actual needs and is not limited thereto.

[0117] Among them, the first feeding end and the first grounding end of the circuit board 5 can be set on the side of the circuit board 5 close to the patch antenna 2, so that the first feeding spring 13 and the first grounding spring 14 can be directly connected to the feeding point and grounding point of the first pattern antenna 3.

[0118] like Figure 3 As shown, in some embodiments, the antenna module further includes: a second feeding spring 15 and / or a second grounding spring 16, the second feeding spring 15 is arranged at the second feeding end of the circuit board 5, and the second feeding spring 15 and the feeding point of the second pattern antenna 4 are abutted, and the second grounding spring 16 is arranged at the second grounding end of the circuit board 5, and the second grounding spring 16 and the feeding point of the second pattern antenna 4 are abutted.

[0119] It can be understood that because the second feeding spring 15 is set at the second feeding end of the circuit board 5 and the second feeding spring 15 abuts the feeding point of the second pattern antenna 4, the second feeding end of the circuit board 5 can use the second feeding spring 15 to feed the excitation signal to the feeding point of the second pattern antenna 4; because the second grounding spring 16 is set at the second grounding end of the circuit board 5 and the second grounding spring 16 abuts the feeding point of the second pattern antenna 4, the second grounding end of the circuit board 5 can use the second grounding spring 16 to receive the ground return signal from the grounding point of the second pattern antenna 4. Therefore, through the cooperation of the second feeding spring 15 and the second grounding spring 16, it is ensured that the second pattern antenna 4 can generate a resonant current and stably radiate the third signal.

[0120] It should be noted that the second feeding spring 15 is used for electrical connection between the second feeding end of the circuit board 5 and the feeding point of the second pattern antenna 4. The specific type of the second feeding spring 15 can be set according to actual needs and is not limited to this.

[0121] The second grounding spring 16 is used for electrical connection between the second grounding end of the circuit board 5 and the grounding point of the second pattern antenna 4 . The specific type of the second grounding spring 16 can be set according to actual needs and is not limited thereto.

[0122] Among them, the second feeding end and the second grounding end of the circuit board 5 can be set on the side of the circuit board 5 close to the patch antenna 2, so that the second feeding spring 15 and the second grounding spring 16 can be directly connected to the feeding point and grounding point of the second pattern antenna 4.

[0123] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the antenna module further includes: an insulating bracket 17, the insulating bracket 17 is arranged in the insulating shell 1 along the planar direction of the insulating shell 1, and the patch antenna 2, the insulating bracket 17 and the circuit board 5 are stacked in sequence along the thickness direction of the insulating shell 1, the first pattern antenna 3 and the insulating bracket 17 are connected along the first direction, and the second pattern antenna 4 and the insulating bracket 17 are connected along the second direction.

[0124] It can be understood that through the setting of the insulating bracket 17, the patch antenna 2, the circuit board 5, the first pattern antenna 3 and the second pattern antenna 4 are stably arranged in the insulating shell 1, and the patch antenna 2, the first pattern antenna 3 and the second pattern antenna 4 are kept away from each other, thereby ensuring high-performance communication of the antenna module.

[0125] It should be noted that the insulating bracket 17 is used to support components such as the patch antenna 2, the circuit board 5, the first pattern antenna 3 and the second pattern antenna 4. The specific type of the insulating bracket 17 can be set according to actual needs and is not limited to this. For example, the insulating bracket 17 can be a plastic bracket.

[0126] Among them, in the specific arrangement, the insulating bracket 17 and the power supply component 6 are spaced apart along the second direction, and the second pattern antenna 4 is located at the end of the insulating bracket 17 away from the power supply component 6, the insulating bracket 17 and the interface component 12 are spaced apart along the first direction, and the first pattern antenna 3 and the interactive component 7 are located at the end of the insulating bracket 17 away from the interface component 12. At the same time, the dielectric plate 202 is arranged on the side of the insulating bracket 17 away from the circuit board 5. The cable 8 bypasses the circuit board 5 and passes through part of the insulating bracket 17 and is connected to the feeding probe. The ground pin 9, the first communication pin 10 and the second communication pin 11 all directly pass through the insulating bracket 17.

[0127] In some embodiments, the third signal includes a GPS (Global Positioning System) frequency band signal.

[0128] It is understandable that the antenna module can utilize the second pattern antenna 4 to realize the radiation of GPS frequency band signals in the thickness direction of the insulating shell 1 , and can realize satellite navigation using the GPS frequency band signals.

[0129] It should be noted that the frequency band of the GPS band signal is 1575MHz.

[0130] In some embodiments, the first signal includes: a Tiantong transmit frequency band signal and / or a Tiantong receive frequency band signal; and / or the second signal includes: a WiFi (Wireless Fidelity) frequency band signal and / or a BT (Bluetooth) frequency band signal.

[0131] It can be understood that the antenna module can use the patch antenna 2 to realize the radiation of Tiantong transmit frequency band signals and / or Tiantong receive frequency band signals in the thickness direction of the insulating shell 1, and can use Tiantong transmit frequency band signals and / or Tiantong receive frequency band signals to realize satellite communication.

[0132] The antenna module can utilize the first pattern antenna 3 to radiate WiFi band signals and / or BT band signals in the thickness direction of the insulating shell 1 , and can utilize WiFi band signals and / or BT band signals to achieve terminal communication.

[0133] It should be noted that the frequency band range of Tiantong's transmit band signals is 1980MHz-2010MHz, and the frequency band range of Tiantong's receive band signals is 2170MHz-2200MHz.

[0134] The frequency range of WiFi band signal is 5200MHz-5800MHz.

[0135] The frequency range of BT band signals is 2410MHz-2490MHz.

[0136] Based on the simulation of the antenna module of this embodiment, the following is obtained: Figures 6 to 8 The circularly polarized gain pattern is shown.

[0137] Figure 6 The circular polarization gain pattern of the antenna module when radiating the Tiantong transmit frequency band signal and the Tiantong receive frequency band signal, from Figure 6 It can be seen that the main radiation intensity of the antenna module is toward the zenith (the direction from the circuit board 5 to the patch antenna 2), which meets the requirements of Tiantong frequency band communication.

[0138] Figure 7 is the circular polarization gain pattern when the antenna module radiates WiFi band signals and BT band signals, from Figure 7 It can be seen that the antenna module has relatively uniform gain coverage in the entire space, which can ensure that the mobile terminal can be stably connected to the antenna module at different positions in the space.

[0139] Figure 8 is the circular polarization gain pattern when the antenna module radiates GPS frequency band signals, from Figure 8 It can be seen from the figure that the antenna module mainly covers the upper half of the space (the side of the patch antenna 2 away from the circuit board 5), which can ensure the strength of the satellite navigation signal.

[0140] The structural layout of the antenna module of this embodiment ensures that each component works effectively while also fully utilizing the radiation performance of the antenna module.

[0141] The embodiment of the present disclosure further provides a vehicle, comprising: an antenna module as in the embodiment of the present disclosure.

[0142] It can be understood that since the patch antenna 2 is arranged in the insulating shell 1 along the planar direction of the insulating shell 1, and the patch antenna 2 radiates the first signal along the thickness direction of the insulating shell 1, the antenna module can realize the radiation of the first signal in the thickness direction of the insulating shell 1, and can use the first signal to achieve communication; since the first pattern antenna 3 is arranged in the insulating shell 1 along the thickness direction of the insulating shell 1, and the first pattern antenna 3 radiates the second signal along the thickness direction of the insulating shell 1, the antenna module can realize the radiation of the second signal in the thickness direction of the insulating shell 1, and can use the second signal to achieve communication.

[0143] Therefore, the cooperation of the patch antenna 2 and the first pattern antenna 3 meets the different communication requirements of the antenna module. At the same time, since the patch antenna 2 radiates the first signal along its thickness direction and the first pattern antenna 3 radiates the second signal along its plane direction, the patch antenna 2 is arranged along the plane direction of the insulating shell 1, and the first pattern antenna 3 is arranged along the thickness direction of the insulating shell 1. This not only realizes the common aperture of the patch antenna 2 and the first pattern antenna 3, but also makes full use of the extreme space in the insulating shell 1 while ensuring a larger distance between the patch antenna 2 and the first pattern antenna 3, thereby effectively improving the isolation between the patch antenna 2 and the first pattern antenna 3, reducing the mutual influence between the patch antenna 2 and the first pattern antenna 3, and thus ensuring the higher communication performance of the antenna module.

[0144] 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, a hybrid vehicle, etc. The vehicle has a vehicle networking system, and the antenna module can be a Tbox (Telematics BOX) in the vehicle networking system.
