[0047] The following description is intended to illustrate the general principles of the invention and is not to be taken in a limiting sense. The scope of the invention is best determined with reference to the appended claims.

[0048] Figure 1A It is a perspective view of a part of the wireless communication device according to the first embodiment of the present invention. Figure 1B yes Figure 1A 1B is an enlarged view of part 1B. Figure 1A and 1B, the wireless communication device C includes a circuit board 1, an antenna module 2, a housing 3 and a metal pattern unit 4 (or a pattern layer 4). The antenna module 2 is coupled to the circuit board 1. The wireless communication device C may also include a screen 50. In some embodiments, the housing 3 (or most of the housing 3) and the screen 50 may be roughly arranged on opposite sides of the circuit board 1. A metal sheet 5 is also provided between the screen 50 and the circuit board 1. In some embodiments, the antenna module 2 and the screen 50 may be roughly arranged on opposite sides of the circuit board 1. The metal pattern unit 4 may be arranged on the inner side wall of the housing 3 or on some parts of the inner side of the housing 3. In some embodiments, the antenna module 2 may be arranged face to face with the metal pattern unit 4. For example, the antenna module 2 and the metal pattern unit 4 are arranged in a manner of directly facing each other from the front, or the metal pattern unit 4 is arranged at a certain angle relative to the antenna module 2, etc., which can be freely arranged as needed. For example, in some embodiments, the inner side wall of the housing 3 may be curved, so that the metal pattern unit 4 may not be arranged directly facing the antenna module 2 from the front. In some embodiments, the metal pattern unit 4 may be composed of a plurality of patterns, for example, a plurality of patterns forming a regular array, or a plurality of patterns arranged randomly; wherein the plurality of patterns may be arranged in one row or in multiple rows. Of course, the distribution of the metal pattern unit 4 (or a plurality of patterns) corresponds to the radiation area of ​​the antenna module 2.

[0049] In one embodiment, the antenna module 2 can be directly mounted on the circuit board 1. However, the disclosed content is not intended to limit the present invention. For example, in another embodiment, the antenna module 2 can be coupled to the circuit board 1 through a flexible circuit board, etc. Therefore, the antenna module 2 can be directly or indirectly mounted on the circuit board 1. In some embodiments, the antenna module 2 (or the antenna unit on the antenna module 2) faces the outside of the wireless communication device so as to transmit antenna signals (or wireless signals) outward. In some embodiments, the direction of the antenna module 2 (or the antenna unit on the antenna module 2) can be defined as the X direction, and the X direction is roughly aligned with the entire plane of the circuit board 1 (or Figure 1A The direction perpendicular to the entire plane of the circuit board 1 can be defined as the Z direction. Figure 1A The Z direction may be perpendicular to the X direction and upward. Figure 1AAs shown, the side above the circuit board 1 can be called the back cover side, and the side below the circuit board 1 can be called the screen side. The housing 3 (or most of the housing 3) can be on the back cover side, and the antenna module 2 (or at least a part of the antenna module 2) can be on the back cover side. The screen 50 (or most of the screen 50) can be on the screen side, and the metal sheet 5 can also be on the screen side. For the convenience of description, other components of the wireless communication device, such as a battery, a middle frame, etc. are not shown in the figure, but it can be understood that the wireless communication device can add other components as needed, or change the position and setting of some of the components.

[0050] Figure 2A FIG. 4 is a side view of an antenna module according to a second embodiment of the present invention. Figure 2B is a perspective view of an antenna module according to a second embodiment of the present invention. Figure 1B , 2A In one embodiment, the antenna module 2 transmits wireless signals. In some embodiments, along the X direction, the antenna module 2 (the outer surface) can be set to be flush with the side 13 of the circuit board 1 (or the screen 50), or the antenna module 2 (the outer surface) can be lower or higher than the side 13 of the circuit board 1 (or the screen 50). These can be freely set according to requirements. For ease of description and understanding, Figure 2A In the example shown, along the X direction, the (outer surface of) antenna module 2 is higher than the side surface 13 of circuit board 1 (or screen 50), and the portion of housing 3 provided with metal pattern unit 4 and the metal pattern unit 4 are both arranged facing antenna module 2. Figure 2A In the embodiment, the antenna module 2 can be mounted on the circuit board 1 by a bracket or a fixing device. Figure 2AThe examples shown are for illustration only and are not intended to limit the present invention. The antenna module 2 defines a first FOV (Field of View) area F1 and a second FOV area F2. The first FOV area F1 is different from the second FOV area F2. The first FOV area F1 and the second FOV area F2 together can constitute a complete FOV area (e.g., called a total FOV area) of the antenna module 2, and the first FOV area F1 and the second FOV area F2 can be divided by the center line of the antenna module 2. In some embodiments, for example, the size of the area covered by the first FOV area F1 and the second FOV area F2 can be the same, or different, which can be divided as needed. In this embodiment, it can be described that the size of the area covered by the first FOV area F1 and the second FOV area F2 is the same. The housing 3 covers the antenna module 2. The housing 3 may include a first cover portion 33 corresponding to the first FOV area F1, and a second cover portion 34 corresponding to the second FOV area F2. The first cover portion 33 and the second cover portion 34 are both within the complete FOV area (range). In one example, the first cover portion 33 and the second cover portion 34 may be symmetrically arranged about the center line of the antenna module 2. The first cover portion 33 and the second cover portion 34 may be made of the same material, for example, the first cover portion 33 and the second cover portion 34 may be an integral structure. Either the first cover portion 33 or the second cover portion 34 may be referred to as a cover portion. The first cover portion 33 has a first equivalent dielectric constant. The metal pattern unit 4 corresponds to the second FOV area F2. Figure 2AIn the illustrated embodiment, the metal pattern unit 4 is only disposed on the second cover 34 (no metal pattern unit or pattern is disposed on or within the first cover 33), and the metal pattern unit 4 is disposed on the inner surface 32 of the housing 3. In some embodiments, the second cover 34 also has a first equivalent dielectric constant, and since the metal pattern unit 4 is disposed on the inner surface of the second cover 34, the combined structure of the second cover 34 and the metal pattern unit 4 has a second equivalent dielectric constant, that is, the metal pattern unit 4 causes or causes the equivalent dielectric constant of the combined structure to change, and the combined structure may have a second equivalent dielectric constant. Therefore, in some embodiments of the present invention, the metal pattern unit 4 causes the second equivalent dielectric constant, that is, the metal pattern unit 4 causes the combined structure of the metal pattern unit 4 and the second cover 34 to have a second equivalent dielectric constant. The first equivalent dielectric constant is different from the second equivalent dielectric constant. For example, the second equivalent dielectric constant is greater than the first equivalent dielectric constant, or the second equivalent dielectric constant is less than the first equivalent dielectric constant. In some embodiments, for example, each pattern in the metal pattern unit 4 is a closed frame structure, that is, each pattern includes a closed ring with a hollow in the middle, and the shape of the closed ring can be rectangular, circular, triangular, pentagonal, hexagonal, etc. In some embodiments, for example, the metal pattern unit 4 is only used to reduce the equivalent dielectric constant of the corresponding part of the shell; for example, to reduce the equivalent dielectric constant of the second cover 34.

[0051] In one embodiment, the first FOV region F1 and the second FOV region F2 are defined according to the geometric center of the antenna module 2. This summary is not intended to limit the present invention.

[0052] refer to Figure 2B In one embodiment, the metal pattern unit 4 includes a plurality of metal strip patterns 41 (or simply referred to as patterns 41). In some embodiments, each metal strip pattern 41 may be a hollow rectangular frame or rectangular ring, a hollow circular frame or circular ring, a hollow triangular frame or triangular ring, a hollow pentagonal frame or pentagonal ring, a hollow hexagonal frame or hexagonal ring, and the like. Thus, different pattern shapes are used to achieve the effect of changing the equivalent dielectric constant of the corresponding structure. Each pattern 41 (or metal strip pattern 41) of the metal pattern unit 4 may be a hollow ring or frame structure.

[0053] refer to Figure 2BIn one embodiment, the metal pattern unit 4 includes a plurality of metal strip rectangles (metal strip patterns) 41, the wavelength of the wireless signal is λ, and the side length d1 of each metal strip rectangle 41 is less than λ / 2. The side length d1 of the metal strip rectangle 41 can be the side length of any side of the rectangle. In some embodiments, the perimeter of the metal strip rectangle 41 can be greater than λ / 2 and less than 2λ. Thereby achieving the effect of changing the equivalent dielectric constant of the corresponding structure.

[0054] Figure 3 FIG. 1 is a perspective view of an antenna module according to a third embodiment of the present invention. Figure 3 In this embodiment, the metal pattern unit 4' includes a plurality of metal strip circles 42, the wavelength of the wireless signal is λ, and the diameter d2 of each metal strip circle 42 is less than λ / 2. In some embodiments, each metal strip circle 42 can be a hollow circular frame or a circular ring.

[0055] refer to Figure 2B In one embodiment, the metal strip patterns 41 are arranged in a matrix and are located within the radiation region of the antenna module 2. Thus, different pattern distributions are used to achieve the effect of changing the equivalent dielectric constant of the corresponding structure.

[0056] See also Figure 2A and Figure 2B In one embodiment, the metal pattern unit 4 is disposed on the inner surface 32 of the shell 3, but this disclosure is not intended to limit the present invention. For example, in another embodiment, the metal pattern unit 4 may be embedded in the shell 3, and the second equivalent dielectric constant is the equivalent dielectric constant of the combination (structure) of the metal pattern unit 4 and the shell 3 on which the metal pattern unit 4 is disposed.

[0057] See also Figure 1A and Figure 1B In one embodiment, the wireless communication device C further includes an electromagnetic shielding portion, which may be a metal sheet, a screen, an adapter card, a flexible circuit board or other components. In this embodiment, the electromagnetic shielding portion may be a metal sheet 5 and / or a screen 50. The antenna module 2 is disposed on the first surface 11 of the circuit board 1 (or the antenna module 2 is located on one side of the first surface 11 of the circuit board 1), the metal sheet 5 is opposite to the second surface 12 of the circuit board 1, the first surface 11 is opposite to the second surface 12, and the antenna module 2 faces the lateral direction X of the wireless communication device C. In one embodiment, the lateral direction X is parallel to the circuit board 1.

[0058] refer to Figure 2AIn one embodiment, the first cover portion 33 is relatively close to the metal sheet 5 and the screen 50 in the vertical direction Z, the second cover portion 34 is relatively far away from the metal sheet 5 and the screen 50 in the vertical direction Z, and the metal pattern unit 4 is relatively far away from the metal sheet 5 and the screen 50 in the vertical direction Z. The first equivalent dielectric constant of the first cover portion 33 is greater than the second equivalent dielectric constant of the combined structure of the second cover portion 34 and the metal pattern unit 4. In this embodiment, the vertical direction Z is perpendicular to the entire horizontal plane of the circuit board 1.

[0059] The millimeter wave signal of the antenna module may be blocked by the electromagnetic shielding part such as the screen of the wireless communication device, thereby affecting the signal transmission on the screen side of the wireless communication device. In the embodiment of the present invention, the spherical coverage of the wireless signal of the antenna module 2 will be biased towards the area with a larger equivalent dielectric constant. Therefore, after the metal pattern unit 4 is set on the second cover part 34, the second equivalent dielectric constant of the combined structure of the second cover part 34 and the metal pattern unit 4 is smaller than the first equivalent dielectric constant of the first cover part 33. Thus, the spherical coverage of the wireless signal of the antenna module 2 will be deflected toward the position where the first cover part 33 and the metal sheet 5 or the screen 50 are located (or the energy intensity distribution of the antenna signal is changed), so that the energy intensity of the antenna signal on the side of the metal sheet 5 or the screen 50 can be improved (or increased), thereby improving the distribution of the energy intensity of the antenna signal and improving the speed and success rate of signal transmission. The metal pattern unit 4 of this embodiment can compensate for the influence of the electromagnetic shielding part (metal sheet 5 or screen 50) and improve the signal transmission of the wireless communication device. In one embodiment, the spherical coverage rate of the wireless signal on the screen side of the wireless communication device of the embodiment of the present invention can be increased from 36.7% to 42.5%, but the disclosed content is not intended to limit the present invention. In some embodiments, reference Fig.16 As shown, in the wireless communication device C, the circuit board 1 can be used as a boundary. In the Z direction (the direction perpendicular to the horizontal plane of the circuit board 1), the side located above the circuit board 1 can be called the back cover side, and the side located below the circuit board 1 can be called the screen side. Most of the housing 3, at least a portion of the antenna module 2, at least a portion of the metal pattern unit 4, and at least a portion of the lining portion 39 (optional) can be located on the back cover side. The screen 50 and most of the metal sheet 5 can be located on the screen side. Fig.17 As shown, Fig.17 It is a schematic diagram of antenna radiation, wherein the dotted line 171 represents the coverage range of the signal strength (or energy strength) of the antenna signal without deflection in the prior art, and the solid line 172 represents the coverage range of the signal strength (or energy strength) of the antenna signal after deflection using an embodiment of the present invention. It can be seen that by using an embodiment of the present invention, the coverage range of the signal strength (or energy strength) of the antenna signal on the screen side is significantly improved.

[0060] Furthermore, in some embodiments, for example Fig.16 As shown, the lining portion 39 may be a structure that is integrated with the shell 3, or the lining portion 39 may be a structure that is separate from the shell 3. In some embodiments, by setting the lining portion 39, the inner surface where the metal pattern unit 4 is located (for example, the inner surface of the shell 3) may be parallel to the surface of the antenna module 2 facing outward, thereby facilitating the adjustment of the equivalent dielectric constant to adjust the deflection. In some embodiments, the lining portion 39 may be omitted, and the metal pattern unit 4 may be arranged on the inner surface of the curved surface of the shell 3; therefore, the inner surface where the metal pattern unit 4 is located (for example, the inner surface of the shell 3) may not be parallel to the surface of the antenna module 2 facing outward, thereby providing different designs and improving the flexibility of the design. Therefore, either or both of the first cover portion 33 and the second cover portion 34 may be a curved structure (for example, in the cross-sectional view); or either or both of the first cover portion 33 and the second cover portion 34 may be a flat structure (for example, in the cross-sectional view). In some embodiments, for example Fig.16 As shown, the antenna module 2 can be mounted on the circuit board 1 by means of a fixing member or a fixing device, or the antenna module 2 can be directly mounted on the circuit board 1 to flexibly adjust the position, orientation, direction, etc. of the antenna module 2.

[0061] In the above embodiment, the metal pattern unit 4 of this embodiment can be used to compensate for the influence of the electromagnetic shielding part, but the present invention is not limited thereto. For example, in another embodiment, the metal pattern unit 4 can be used to deflect the spherical coverage of the wireless signal of the antenna module 2 away from the user to reduce the electromagnetic waves absorbed by the user. In practical applications, the equivalent dielectric constant can be set according to requirements to adjust the deflection of the antenna signal to achieve the desired effect.

[0062] Figure 4 FIG. 4 is a side view of an antenna module according to a fourth embodiment of the present invention. Figure 4 , in this embodiment, with Figure 2A Unlike the embodiment shown, the metal pattern unit 4 is relatively close to the metal sheet 5 and the screen 50 in the vertical direction Z; the metal pattern unit 4 is arranged on the first cover portion 33, rather than on the second cover portion 34. The metal pattern unit 4 is arranged on the inner surface 32 of the housing 3. The second equivalent dielectric constant of the second cover portion 34 is greater than the first equivalent dielectric constant of the combined structure of the first cover portion 33 and the metal pattern unit 4. Therefore, the coverage range of the antenna signal will be deflected toward the position where the second cover portion 34 is located, thereby improving the energy intensity of the antenna signal on the side of the first surface 11 of the circuit board 1, thereby improving the speed and success rate of signal transmission. Figure 4 The embodiments can provide different designs to meet different application requirements.

[0063] Please refer to Figure 4 In one embodiment, the metal sheet 5 is a part of the screen 50. The present invention is not limited thereto.

[0064] Figure 5 FIG. 5 is a side view of an antenna module according to a fifth embodiment of the present invention. Figure 5 In one embodiment, the shell 3 covers the antenna module 2. The first cover portion 33 of the shell 3 corresponds to the first FOV area F1. The second cover portion 34 of the shell 3 corresponds to the second FOV area F2. In some embodiments, the equivalent dielectric constants of the first cover portion 33 and the second cover portion 34 can be different without setting the metal pattern unit 4. For example, the first cover portion 33 is made of a first material, and the second cover portion 34 is made of a second material. The first material is different from the second material, and the equivalent dielectric constant of the first material is different from the equivalent dielectric constant of the second material. As a result, the first equivalent dielectric constant of the first cover portion 33 is different from the second equivalent dielectric constant of the second cover portion 34. As a result, the embodiment of the present invention can deflect the coverage range of the antenna signal (or change the energy intensity distribution of the antenna signal) without setting the metal pattern unit 4. In some embodiments, when the first cover portion 33 is made of a first material and the second cover portion 34 is made of a second material, a metal pattern unit 4 may be further provided on (or in) the first cover portion 33 or the second cover portion 34, so that the first equivalent dielectric constant of the first cover portion 33 and the second equivalent dielectric constant of the second cover portion 34 and the metal pattern unit 4 are different, or the first equivalent dielectric constant of the first cover portion 33 and the metal pattern unit 4 and the second equivalent dielectric constant of the second cover portion 34 are different. Figure 5 In the example shown, the metal pattern unit 4 is arranged on the second cover portion 34 (not arranged on or in the first cover portion 33), so that the first equivalent dielectric constant of the first cover portion 33 and the second equivalent dielectric constant of the second cover portion 34 and the metal pattern unit 4 are different, for example, the first equivalent dielectric constant is greater than the second equivalent dielectric constant, but the present invention is not limited to this.

[0065] In an embodiment of the present invention, the size of the first FOV area F1 may be equal to the size of the second FOV area F2. However, the present invention is not limited thereto.

In this embodiment, the second cover portion 34 is provided with a metal pattern unit 4, and the first cover portion 33 does not have a metal pattern unit. The first equivalent dielectric constant of the first cover portion 33 is greater than the second equivalent dielectric constant of the combined structure of the second cover portion 34 and the metal pattern unit 4. Figure 5 The embodiments can provide different designs to meet different application requirements.

[0067] Figure 6 FIG. 6 is a side view of an antenna module according to a sixth embodiment of the present invention. Figure 6 In this embodiment, the first cover portion 33 is provided with a metal pattern unit 4, and the second cover portion 34 does not have a metal pattern unit. In the embodiment of the present invention, the metal pattern unit 4 can be used to increase or decrease the equivalent dielectric constant. For example, the equivalent dielectric constant of the combined structure of the first cover portion 33 and the metal pattern unit 4 can be increased or decreased by changing the arrangement of the metal pattern unit 4; or, the equivalent dielectric constant of the combined structure of the first cover portion 33 and the metal pattern unit 4 can be increased or decreased by changing the outer shape of the pattern in the metal pattern unit 4; or, the equivalent dielectric constant of the combined structure of the first cover portion 33 and the metal pattern unit 4 can be increased or decreased by changing the material of the pattern in the metal pattern unit 4; and so on.

Figure 7In this embodiment, the first cover portion 33 includes a first metal pattern unit 43, and the second cover portion 34 includes a second metal pattern unit 44. In this embodiment, the size of each pattern in the first metal pattern unit 43 is different from the size of each pattern in the second metal pattern unit 44. For example, the size of each pattern in the first metal pattern unit 43 is smaller than the size of each pattern in the second metal pattern unit 44. For example, the first metal pattern unit 43 includes a plurality of first metal strip rectangles 431. The second metal pattern unit 44 includes a plurality of second metal strip rectangles 441. The side length d3 of each first metal strip rectangle 431 is different from the side length d4 of each second metal strip rectangle 441. In some embodiments, for example, the side length d3 of each first metal strip rectangle 431 may be smaller than the side length d4 of each second metal strip rectangle 441; thus, the first equivalent dielectric constant of the combined structure of the first cover portion 33 and the first metal pattern unit 43 is greater than the second equivalent dielectric constant of the combined structure of the second cover portion 34 and the second metal pattern unit 44. In some embodiments, the equivalent dielectric constant can be adjusted by using different pattern sizes, thereby affecting the coverage of the antenna signal (or changing the energy intensity distribution of the antenna signal). Figure 7 The embodiments can provide different designs to meet different application requirements.

[0069] Please refer to Figure 5 , 6 In one embodiment, any one or both of the first cover portion 33 and the second cover portion 34 may be a plane (or flat) portion or a curved (or bent) portion. The present invention is not limited thereto.

[0070] In the above embodiment, the metal pattern unit 4 is disposed on the housing, but the present invention is not limited thereto.

[0071] Figure 8 FIG. 8 is a side view of an antenna module according to an eighth embodiment of the present invention. Figure 8 In one embodiment, the wireless communication device further includes a substrate 6. The substrate 6 is disposed between the antenna module 2 and the housing 3. The metal pattern unit 4 is disposed on the substrate 6. Thus, the metal pattern unit 4 may not be disposed on or within the housing 3, wherein the substrate 6 may be located between the antenna module 2 and the housing 3. The substrate 6 may be mounted on the housing 3 or on the circuit board 1 using a support frame, a bracket, or a fixing device. For example, in Figure 8 In the example shown, the substrate 6 is located between the second cover portion 34 and the antenna module 2, so that the first equivalent dielectric constant of the first cover portion 33 is different from the second equivalent dielectric constant of the combined structure of the second cover portion 34, the substrate 6 and the metal pattern unit 4; for example, the first equivalent dielectric constant is greater than the second equivalent dielectric constant. Figure 8The embodiments can provide different designs to meet different application requirements.

[0072] In the above embodiment, the antenna module 2 is perpendicular to the circuit board 1. However, the present invention is not limited to the present invention. For example, in one embodiment, the antenna module 2 can be parallel to the circuit board 1.

[0073] Fig. 9 FIG. 1 is a side view of a portion of a wireless communication device according to a ninth embodiment of the present invention. Fig. 9 In this embodiment, a wireless communication device C9 is provided. The wireless communication device C9 includes a circuit board 1, an antenna module 2, a shell 3 and a metal pattern unit 4. The antenna module 2 is coupled to the circuit board 1. The antenna module 2 transmits a wireless signal. The antenna module 2 defines a FOV area F. The shell 3 covers the antenna module 2. The metal pattern unit 4 is disposed on the shell 3. The metal pattern unit 4 corresponds to the FOV area. The setting of the metal pattern unit 4 can reduce the equivalent dielectric constant of the part of the shell 3 having the metal pattern unit 4 (relative to the original case where the metal pattern unit 4 is not provided), thereby reducing the reflection of electromagnetic waves and improving the radiation intensity and communication capability of the antenna signal.

[0075] Figures 10 to 15 Schematic diagrams of antenna devices according to various embodiments of the present invention are shown. In some embodiments of the present invention, the antenna device herein can be used in wireless communication devices, such as mobile phones, tablets, routing devices, laptops and other devices. For example, the antenna device can be installed on a circuit board of a wireless communication device or other device, or installed at other locations of the wireless communication device or other device (such as various fixing devices, etc.) to meet the requirements of the antenna function. The antenna device in the embodiment of the present invention can also be installed in other devices or devices that need to use the antenna function, such as Internet of Things devices, vehicle-mounted devices, etc.

[0076] refer to Fig.10 , Fig.10A schematic diagram of an antenna device according to some embodiments of the present invention is shown. In some embodiments, the antenna device 100 includes an antenna module 2 and a housing (or cover) 3 above the antenna module 2. There is a distance between the antenna module 2 and the housing 3, and the space may be a medium such as air. The antenna module 2 is used to transmit wireless signals, and the housing 3 is arranged in the direction of transmitting wireless signals toward the antenna module 2. The antenna device 100 also includes a pattern layer 4, which can be arranged between the antenna module 2 and the housing 3, or on or inside the housing 3. There will also be a spacing distance between the pattern layer 4 and the antenna module 2, and the pattern layer 4 and the antenna module 2 may not be in direct contact, and the pattern layer 4 and the antenna module 2 are separated by air or other dielectrics. The pattern layer 4 can be arranged within the FOV area (range) of the antenna module 2. The antenna module 2 can transmit antenna signals in the direction toward the housing 3. The housing 3 and the antenna module 2 can be connected and fixed to each other by a support frame, a bracket, a support column, or a fixing device thereof to control the spacing distance between the two (or more components) to remain fixed at least for a period of time. In some embodiments, the antenna module 2 has a center line CL perpendicular to the signal transmission surface of the antenna module 2. The housing 3 has a first cover 33 and a second cover 34. The first cover 33 and the second cover 34 are both within the FOV area (range) of the antenna module 2. The first cover 33 and the second cover 34 are symmetrically arranged about the center line CL. The first cover 33 and the second cover 34 can use the same material, for example, the two are an integral structure; or the first cover 33 and the second cover 34 are split structures using the same material and then fixed to each other; or the first cover 33 and the second cover 34 are split structures using different materials and then fixed to each other. In some embodiments, the pattern layer 4 is set at a position corresponding to at least one of the first cover portion 33 and the second cover portion 34; for example, the pattern layer 4 can be set only on the first cover portion 33, or only on the second cover portion 34, or on the first cover portion 33 and the second cover portion 34; for another example, the pattern layer 4 can be set only at a position corresponding to the first cover portion 33 without contacting the first cover portion 33 (or not directly located on the first cover portion 33), or only at a position corresponding to the second cover portion 34 without contacting the second cover portion 34 (or not directly located on the second cover portion 34), or at a position corresponding to the first cover portion 33 and a position corresponding to the second cover portion 34 without contacting the first cover portion 33 and the second cover portion 34 (or not directly located on the first cover portion 33 and the second cover portion 34).

[0077] exist Fig.10In the example shown, a pattern layer 4 is provided on or inside the first cover 33 and on or inside the second cover 34, and the pattern layer 4 can be a metal material or a non-metal material. For example, the pattern layer 4 includes a first pattern portion corresponding to the first cover 33 and a second pattern portion corresponding to the second cover 34. The first pattern portion and the second pattern portion of the pattern layer 4 can respectively include one or more patterns 45, each of which is a closed frame structure, that is, each pattern includes a closed ring with a hollow in the middle, and the shape of the closed ring can be a rectangle, a circle, a triangle, a pentagon, a hexagon, etc. In some embodiments, the wavelength of the wireless signal emitted by the antenna module 2 is λ, and the side length or diameter or inner diameter d5 of each pattern 45 is less than λ / 2. Through the above-mentioned setting of the present embodiment, the setting of the pattern layer 4 can reduce the equivalent dielectric constant of the combined structure of the housing 3 and the pattern layer 4 (relative to the original absence of the pattern layer 4), thereby reducing the reflection of electromagnetic waves and improving the radiation intensity and communication capability of the antenna signal.

[0078] In some embodiments, Fig.10 As shown, the pattern layer 4 (e.g., the first pattern portion and the second pattern portion) disposed on both sides of the center line CL may be symmetrical; for example, the patterns 45 (i.e., the patterns in the first pattern portion and the patterns in the second pattern portion) disposed on both sides of the center line CL may be equal in number, equal in size, or symmetrical in distribution position about the center line CL. In other words, Fig.10 In the example of , the size and number of the patterns in the first pattern portion are the same as the size and number of the patterns in the second pattern portion. This achieves the desired effect of reducing the reflection of electromagnetic waves and improving the radiation intensity and communication capability of the antenna signal. Fig.10 In the example shown, the direction p in which the signal strength (or energy strength) in the antenna radiation pattern of the antenna device 100 is the largest may coincide with the center line CL, that is, Fig.10 The combined structure of the shell 3 and the pattern layer 4 in the example does not deflect the coverage of the antenna signal (or does not change the distribution of the energy intensity (or signal intensity) of the antenna signal). The direction p with the maximum signal intensity (or energy intensity) in the antenna radiation pattern can also be called the beam peak direction p or the main beam direction p.

[0079] In some other embodiments, the pattern layer 4 (e.g., the first pattern portion and the second pattern portion) disposed on both sides of the center line CL may be asymmetric; for example, the number of patterns 45 (i.e., the pattern in the first pattern portion and the pattern in the second pattern portion) disposed on both sides of the center line CL is not equal, the size is not equal, and / or the distribution position is asymmetric about the center line CL. To achieve effects such as deflecting the coverage of the antenna signal (or changing the energy intensity distribution of the antenna signal). Therefore, in an embodiment of the present invention, the number and / or size of the patterns in the first pattern portion may be the same or different from the number and / or size of the patterns in the second pattern portion to achieve different deflection effects. For example, the number of patterns in the first pattern portion may be the same or different from the number of patterns in the second pattern portion; or, the size of the patterns in the first pattern portion may be the same or different from the size of the patterns in the second pattern portion; or, the number and size of the patterns in the first pattern portion may be the same or different from the number and size of the patterns in the second pattern portion. Thus, the flexibility of design is achieved to meet different needs.

[0080] In some embodiments, the housing 3 includes a portion corresponding to the FOV area of ​​the antenna module 2, for example, the first cover portion 33 and the second cover portion 34 are both located within the portion corresponding to the FOV area of ​​the antenna module 2, and the pattern layer 4 can be arranged on or within the corresponding portion. In some embodiments, the pattern layer 4 can be arranged at any position of the spacing distance between the antenna module 2 and the housing 3, for example, the pattern layer 4 is not arranged on or within the housing 3, but is arranged on a component such as a substrate between the antenna module 2 and the housing 3. The substrate and other components can be fixedly connected to the antenna module 2 and / or the housing 3 by a fixing device such as a bracket. Of course, no matter whether the pattern layer 4 is arranged on other components such as the housing or the substrate, the pattern layer 4 is located at a position corresponding to the FOV area of ​​the antenna module 2, or is within the FOV area.

[0081] refer to Fig.11 , Fig.11 Schematic diagrams of antenna devices according to some embodiments of the present invention are shown. Fig.11 The example shown is similar to Fig.10 The difference between the examples shown is that Fig.11 In the antenna device 110 shown, the pattern layer 4 is only provided on the second cover portion 34, and the pattern layer 4 is not provided on the first cover portion 33. The pattern layer 4 can be made of metal or non-metal. Of course, it is understandable that the pattern layer 4 can be provided on other components such as a substrate instead of on the housing 3. Thus, the pattern layer 4 can only have the second pattern portion but not the first pattern portion, and the second pattern portion corresponds to the second cover portion 34. Fig.11In an exemplary manner, the second equivalent dielectric constant of the combined structure of the second cover 34 and the pattern layer 4 can be made smaller than the first equivalent dielectric constant of the first cover 33 (without the pattern layer). This can deflect the coverage of the antenna signal (or change the energy intensity distribution of the antenna signal) so that the peak direction of the energy intensity of the antenna signal is deflected toward the first cover 33 with a higher equivalent dielectric constant. Fig.11 The main beam direction p shown has an angle β with the center line CL, for example, the angle β may be 30° or 40°, etc. (these values ​​are only examples, and the angle β may be any value in the range of greater than 0° to less than or equal to 90° (0°<β≤90°)). Therefore, Fig.11 The example shown can be applied to designs that require deflection of the main beam direction p to meet different design requirements.

[0082] refer to Fig.12 , Fig.12 Schematic diagrams of antenna devices according to some embodiments of the present invention are shown. Fig.12 The example shown is similar to Fig.10 The difference between the examples shown is that Fig.12 In the antenna device 120 shown, the pattern layer 4 is only provided on the first cover portion 33, and the pattern layer 4 is not provided on the second cover portion 34. The pattern layer 4 may be, for example, a non-metallic material or a metal material. Of course, it is understandable that the pattern layer 4 may be provided on other components such as a substrate instead of on the housing 3. Thus, the pattern layer 4 may only have a first pattern portion but not a second pattern portion, and the first pattern portion corresponds to the first cover portion 33. Fig.12 In the example of FIG. 4 , each pattern 45 in the pattern layer 4 may have a shape different from Fig.11 The pattern in the example has a shape, or / and Fig.12 In the example of Fig.11 The pattern material in the example. Fig.12 In an exemplary manner, the first equivalent dielectric constant of the combined structure of the first cover 33 and the pattern layer 4 can be made greater than the second equivalent dielectric constant of the second cover 34 (without the pattern layer). This can deflect the coverage of the antenna signal (or change the energy intensity distribution of the antenna signal) so that the energy intensity peak direction of the antenna signal is deflected toward the combined structure of the first cover 33 and the pattern layer 4 with a higher equivalent dielectric constant. For example Fig.12 The main beam direction p shown has an angle β with the center line CL, for example, the angle β may be 30° or 40°, etc. (these values ​​are only examples, and the angle β may be any value in the range of greater than 0° to less than or equal to 90° (0°<β≤90°)). Therefore, Fig.12The example shown can be applied to designs that require deflection of the main beam direction p to meet different design requirements.

[0083] refer to Fig.13 , Fig.13 Schematic diagrams of antenna devices according to some embodiments of the present invention are shown. Fig.13 The example shown is similar to Fig.11 The difference between the examples shown is that Fig.13 In the antenna device 130 shown, the number of patterns 45 on the pattern layer 4 on the second cover portion 34 is less than Fig.11 The pattern layer on the second cover portion shown in FIG. 4 may be made of metal or non-metal. Thus, the pattern layer 4 may only have the second pattern portion without the first pattern portion, and the second pattern portion corresponds to the second cover portion 34. Fig.13 In an exemplary manner, the second equivalent dielectric constant of the combined structure of the second cover portion 34 and the pattern layer 4 can be made smaller than the first equivalent dielectric constant of the first cover portion 33 (without the pattern layer). Fig.13 In the example, the second equivalent dielectric constant of the combined structure of the second cover portion 34 and the pattern layer 4 is greater than Fig.11 The equivalent dielectric constant of the combined structure of the second cover and the pattern layer is 0.0447 W / m. This can deflect the coverage of the antenna signal (or change the energy intensity distribution of the antenna signal) so that the energy intensity peak direction of the antenna signal is deflected toward the first cover 33 with a higher equivalent dielectric constant, and the deflection angle is smaller than that of the first cover 33. Fig.11 The example is smaller. Fig.13 The main beam direction p shown has an angle β with the center line CL (the angle β is less than Fig.11 The angle β in the figure is 15° or 20° (these values ​​are for example only, and the angle β can be any value in the range of greater than 0° to less than or equal to 90° (0°<β≤90°)). Therefore, Fig.13 The example shown can be applied to designs that require deflection of the main beam direction p. At the same time, the deflection angle can be adjusted by changing the number of patterns, thereby providing different angle deflections to meet different design requirements.

[0084] In some embodiments, the equivalent dielectric constant of the combined structure of the cover (the first cover and / or the second cover) and the pattern layer can be adjusted in other ways. For example, the size, distribution position, etc. of the pattern in the pattern layer can be adjusted. Therefore, any one or more of the number, size, and distribution position of the pattern can be adjusted to achieve different equivalent dielectric constants, thereby adjusting the direction and angle of the deflection of the main beam direction p. For example, in Fig.13In the example shown, in addition to reducing the number of patterns in the pattern layer 4, the size (side length, diameter or inner diameter, etc.) of the pattern 45 in the pattern layer 4 on the second cover portion 34 can also be reduced so that the size of the pattern 45 is smaller than d5 to achieve different design requirements.

[0085] refer to Fig.14 , Fig.14 Schematic diagrams of antenna devices according to some embodiments of the present invention are shown. Fig.14 The example shown is similar to Fig.12 The difference between the examples shown is that Fig.14 In the antenna device 140 shown, the number of patterns 45 on the pattern layer 4 on the first cover portion 33 is less than Fig.12 The pattern layer on the first cover portion shown in FIG. 4 may be made of metal or non-metal. Thus, the pattern layer 4 may only have the first pattern portion but not the second pattern portion, and the first pattern portion corresponds to the first cover portion 33. Fig.14 In an exemplary manner, the first equivalent dielectric constant of the combined structure of the first cover portion 33 and the pattern layer 4 can be made greater than the second equivalent dielectric constant of the second cover portion 34 (without the pattern layer). Fig.14 In the example, the second equivalent dielectric constant of the combined structure of the first cover portion 33 and the pattern layer 4 is greater than Fig.12 In this way, the coverage of the antenna signal can be deflected (or the energy intensity distribution of the antenna signal can be changed), so that the energy intensity peak direction of the antenna signal is deflected toward the direction of the combination structure of the first cover part 33 and the pattern layer 4 with a higher equivalent dielectric constant, and the deflection angle is smaller than that of the first cover part 33 and the pattern layer 4. Fig.12 The example will be smaller (because Fig.14 The difference between the first equivalent dielectric constant of the combined structure of the first cover portion 33 and the pattern layer 4 and the second equivalent dielectric constant of the second cover portion 34 is small). Fig.14 The main beam direction p shown has an angle β with the center line CL (the angle β is less than Fig.12 The angle β in the figure is 15° or 20° (these values ​​are for example only, and the angle β can be any value in the range of greater than 0° to less than or equal to 90° (0°<β≤90°)). Therefore, Fig.14 The example shown can be applied to designs that require deflection of the main beam direction p. At the same time, the deflection angle can be adjusted by changing the number of patterns, thereby providing different angle deflections to meet different design requirements.

[0086] In some embodiments, the equivalent dielectric constant of the combined structure of the cover (the first cover and / or the second cover) and the pattern layer may be adjusted in other ways. For example, the size, distribution position, etc. of the pattern in the pattern layer may be adjusted. Therefore, any one or more of the number, size, and distribution position of the pattern may be adjusted to achieve different equivalent dielectric constants, thereby adjusting the direction and angle of the deflection of the main beam direction p.

[0087] refer to Fig.15 , Fig.15 Schematic diagrams of antenna devices according to some embodiments of the present invention are shown. Fig.15 The example shown is similar to Fig.11 The difference of the example shown is that a pattern layer 4 is also provided on the first cover part 33, and the size of the pattern 46 of the pattern layer 4 on the first cover part 33 is different from the pattern 45 of the pattern layer 4 on the second cover part 34. Thus, the pattern layer 4 can have a first pattern portion and a second pattern portion, the first pattern portion corresponds to the first cover part 33, and the second pattern portion corresponds to the second cover part 34. For example, in Fig.15 In the example of FIG. 1 , the size d6 of the pattern 46 in the first pattern portion is smaller than the size of the pattern 45 in the second pattern portion. Of course, in other embodiments, the size d6 of the pattern 46 may be larger than the size of the pattern 45. This provides different design solutions and meets different requirements. Fig.15 In the example of , the size d6 of pattern 46 is smaller than the size of pattern 45, so that the first equivalent dielectric constant of the combined structure of the first cover portion 33 and the pattern layer 4 having pattern 46 is greater than the second equivalent dielectric constant of the combined structure of the second cover portion 34 and the pattern layer 4 having pattern 45, and the energy intensity peak direction of the antenna signal is deflected toward the first cover portion 33 with a higher equivalent dielectric constant. Fig.15 The main beam direction p shown has an angle β with the center line CL, for example, the angle β may be 40° or 45°, etc. (these values ​​are only examples, and the angle β may be any value in the range of greater than 0° to less than or equal to 90° (0°<β≤90°)). Therefore, Fig.15 The example shown can be applied to designs that require deflection of the main beam direction p, while providing different angles of deflection to meet different design requirements.

[0088] In some embodiments, it can be set that only the size of the pattern in the first pattern portion is different from the size of the pattern in the second pattern portion, and the number of patterns in the first pattern portion and the number of patterns in the second pattern portion can be different or the same. Alternatively, it can be set that only the number of patterns in the first pattern portion is different from the number of patterns in the second pattern portion, and the size of the pattern in the first pattern portion and the size of the pattern in the second pattern portion can be different or the same. Alternatively, it can be set that the size and number of the pattern in the first pattern portion are different from the size and number of the pattern in the second pattern portion. All of these methods can achieve the need to deflect the main beam direction p to meet different design requirements.
