Furthermore, the drawings are not necessarily drawn to scale, and some features may be enlarged to show details of specific components.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of exemplary embodiments may have different values.

[0029] This disclosure provides an antenna device including a first antenna and a second antenna. In this antenna device, by additionally providing a coupling capacitor at the interval between the first antenna and the second antenna, the leakage of the radiated signal of the antenna device to the rear side of the antenna device through the interval is suppressed, so that the antenna device can still maintain a high front-to-back ratio, thereby improving the radiation performance of the antenna device.

[0030] According to an exemplary embodiment of this disclosure, such as Figure 1 As shown, the antenna device may include a first antenna 100, a second antenna 200, and a coupling capacitor 400.

[0031] The first antenna 100 may include a first reflective element 110 configured to reflect at least a portion of the signal radiated by the antenna device. Specifically, the first reflective element 110 may reflect at least a portion of the signal radiated by the first antenna 100, and may also reflect a portion of the signal radiated by the second antenna 200 as described below. The first reflective surface 111 of the first reflective element 110 is disposed facing the front of the antenna device to reflect a rearward-pointing signal. Depending on the requirements, the first reflective surface 111 may be planar or curved. In the following description, a planar first reflective surface 111 will be used as an example, but it is understood that the embodiments of this disclosure are not limited thereto. In some embodiments, the first reflective element 110 may be formed of a conductive metallic material, or the first reflective element 110 may include other materials and a thin metal film deposited on the surface of that material.

[0032] like Figure 1 As shown, the first antenna 100 may further include one or more antenna elements 120. The antenna elements 120 protrude forward from the first reflecting surface 111. A portion of the signal radiated forward by the antenna elements 120 will be directly radiated into the forward space, while a portion of the signal radiated backward by the antenna elements 120 will be reflected forward by at least the first reflecting surface 111 (and some signals may also be reflected by the second reflecting surface 211 described below). The antenna elements 120 may include only a single type of antenna element corresponding to a single frequency band, or they may include multiple types of antenna elements corresponding to multiple frequency bands or having other different properties. Furthermore, multiple antenna elements 120 can be arranged in various ways to ensure that the signal radiated by the first antenna 100 meets specific requirements.

[0033] In one specific embodiment, such as Figure 2As shown, the first antenna 100 may include a plurality of first antenna elements 121 arranged in an array and a plurality of second antenna elements 122 arranged in an array. The first antenna elements 121 may be configured to radiate signals within a first frequency band, and the second antenna elements 122 may be configured to radiate signals within a second frequency band. In some embodiments, at least some frequencies in the second frequency band are higher than the highest frequency in the first frequency band. That is, the first antenna 100 may radiate corresponding signals in two different frequency bands through the first antenna elements 121 and the second antenna elements 122, respectively. For example, the first antenna elements 121 may be configured to radiate signals in the 617-960 MHz frequency band or a portion thereof, and the second antenna elements 122 may be configured to radiate signals in the 1695-2690 MHz frequency band or a portion thereof. In the described embodiment, two rows of first antenna elements 121 and six rows of second antenna elements 122 are provided.

[0034] Similarly, such as Figure 1 As shown, the second antenna 200 may include a second reflective element 210 configured to reflect at least a portion of the signal radiated by the antenna device. Specifically, the second reflective element 210 may reflect at least a portion of the signal radiated by the second antenna 200, and may also reflect a portion of the signal radiated by the first antenna 100. The second reflective surface 211 of the second reflective element 210 is disposed facing the front of the antenna device to radiate the signal forward. Depending on different requirements, the second reflective surface 211 may be planar or curved. In the following description, the second reflective surface 211 will be described as planar, but it is understood that the embodiments of this disclosure are not limited thereto. In some embodiments, the second reflective element 210 may be formed of a conductive metallic material, or the second reflective element 210 may include other materials and a thin metal film deposited on the surface of that material.

[0035] like Figure 1 As shown, the second antenna 200 may further include one or more antenna elements 220 that protrude forward from the second reflector 211. In this case, a portion of the signal radiated forward by the antenna elements 220 will be directly radiated into the forward space, while a portion of the signal radiated backward by the antenna elements 220 will be reflected forward by at least the second reflector 211 (some signals may also be reflected by the first reflector 111). The antenna elements 220 may include only a single type of antenna element corresponding to a single frequency band, or may include multiple types of antenna elements corresponding to multiple frequency bands or having other different properties. Furthermore, multiple antenna elements 220 can be arranged in various ways to ensure that the signal radiated by the second antenna 200 meets specific requirements.

[0036] In one specific embodiment, such as Figure 2As shown, the second antenna 200 may include a plurality of third antenna elements 223 arranged in an array and a plurality of fourth antenna elements 224 arranged in an array. The third antenna elements 223 may be configured to radiate signals within a third frequency band, and the fourth antenna elements 224 may be configured to radiate signals within a fourth frequency band. In a specific example, the third frequency band is the first frequency band. That is, in this case, the first antenna element 121 in the first antenna 100 and the third antenna element 223 in the second antenna 200 jointly participate in radiating signals within the first frequency band. In other words, for signals within the first frequency band, the first antenna 100 and the second antenna 200 can be considered as a single, complete antenna. In some embodiments, at least some frequencies in the fourth frequency band are higher than the highest frequency in the third frequency band or the first frequency band. The fourth frequency band may be the same as or different from the second frequency band. Figure 2 In the specific embodiment shown, the second antenna 200 can radiate corresponding signals in two different frequency bands through the third antenna element 223 and the fourth antenna element 224, respectively. For example, the third antenna element 223 and the fourth antenna element 224 can be configured according to... Figure 2 The arrangement is shown in the 2L4H layout, where the column formed by the third antenna element 223 is located between the two columns of fourth antenna elements 224.

[0037] like Figure 1 and Figure 2 As shown, the first antenna 100 and the second antenna 200 can be separately arranged and electrically connected via, for example, a blind-matching connector. Correspondingly, there is a gap 300 between the first reflective component 110 and the second reflective component 210. The first antenna 100 and the second antenna 200 can be arranged in a vertical direction (i.e., they can be vertically stacked). Figure 2 As shown, the second antenna 200 is positioned below the first antenna 100. However, it is understood that the first antenna 100 and the second antenna 200 can also be arranged in other ways (e.g., arranged in a left-right direction), and this is not a limitation.

[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, the first reflective surface 111 and the second reflective surface 211 can be arranged coplanarly with each other, which helps to avoid mutual interference between the first antenna 100 and the second antenna 200 and improve the radiation effect of the antenna device.

[0039] In some embodiments, both the first antenna 100 and the second antenna 200 may be passive antennas. Alternatively, in other embodiments, at least one of the first antenna 100 and the second antenna 200 may include an active device 500 (see [link to documentation]). Figure 3The active device 500 may include circuits or components such as a receiving module, an amplifying module, and a power supply module. The active device 500 may be positioned behind the first reflector 110 and / or the second reflector 210.

[0040] exist Figure 3 In the specific embodiment shown, the first antenna 100 may include an active device 500, and the active device 500 may be electrically connected to at least some of the antenna elements 120 in the first antenna 100. For example, the active device 500 may be connected to... Figure 2 The second antenna element 122 in the first antenna 100 shown is electrically connected. In other embodiments, the active device 500 may also be electrically connected to the second antenna 200, or the first active device 500 may be included in the first antenna 100, and the second active device 500 may be included in the second antenna 200.

[0041] like Figure 3 and Figure 4 As shown, the first antenna 100 may include a first radome 130, and / or the second antenna 200 may include a second radome 230. The radomes 130 and 230 protect the antennas 100 and 200 from the influence of the external environment. The radomes 130 and 230 are substantially transparent to electromagnetic radiation in the respective operating frequency bands of the antennas 100 and 200, and are mechanically capable of withstanding harsh external environments to prevent damage to the antennas 100 and 200 from rain, snow, dust, and solar radiation. Figure 3 and Figure 4 In the specific embodiment shown, the first reflector 110 and antenna element 120 of the first antenna 100 can be disposed within the first radome 130, and the second reflector 210 and antenna element 220 of the second antenna 200 can be disposed within the second radome 230. Furthermore, the active device 500 of the first antenna 100 can be disposed outside the first radome 130, located at the rear of the first radome 130.

[0042] like Figure 1As shown, the coupling capacitor 400 may include a first electrode 410 and a second electrode 420. Both the first electrode 410 and the second electrode 420 can be disposed close to the gap 300. For example, the first electrode 410 is disposed on the side of the first reflecting surface 111 of the first reflecting member 110 near the gap 300, and the second electrode 420 is disposed on the side of the second reflecting surface 211 of the second reflecting member 210 near the gap 300. The coupling capacitor 400 can suppress the leakage of signals radiated by the antenna device to the rear side of the antenna device through the gap 300. Specifically, due to the presence of the coupling capacitor 400, the influence of the gap 300 on signal transmission is significantly reduced, and when the capacitance value of the coupling capacitor 400 is sufficiently large, the signal transmission will be similar to the signal transmission in the absence of the gap 300 (i.e., the antenna device has a complete reflecting member or reflecting surface).

[0043] The capacitance value of the coupling capacitor 400 is generally determined by its structural parameters, which may specifically include the effective capacitance area and the effective capacitor spacing. The effective capacitance area may correspond to the area of ​​partial or complete overlap between the first electrode 410 and the second electrode 420, and the effective capacitor spacing may be the distance between the overlapping portions of the first electrode 410 and the second electrode 420. In many cases, the interval between the first antenna 100 and the second antenna 200 in the antenna device may be fixed, effectively fixing the effective capacitor spacing. Therefore, the capacitance value of the coupling capacitor 400 can be adjusted to a suitable value by adjusting the effective capacitance area, i.e., adjusting the overlapping area of ​​the first electrode 410 and the second electrode 420. Although a sufficient capacitance value can usually be obtained by increasing the overlapping area, increasing the size of the first electrode 410 and the second electrode 420 may place high demands on the space available for setting the coupling capacitor 400 in the antenna device. Therefore, space constraints may limit the size of the first electrode 410 and the second electrode 420, thereby limiting the effective capacitance area.

[0044] Generally speaking, a 300° spacing has a more significant impact on relatively low-frequency signals than on relatively high-frequency signals. Therefore, when determining the structural parameters of the coupling capacitor 400, it can be configured based on the lowest-frequency portion of the signal radiated by the antenna device. When the radiation effect of the lowest-frequency portion of the signal meets the requirements, the radiation effect of the higher-frequency portion of the signal will usually also meet the requirements.

[0045] In some embodiments, such as Figures 5 to 12 As shown, the first electrode plate 410 and the second electrode plate 420 are parallel to each other to make full use of the limited space and make the capacitance value of the coupling capacitor 400 sufficiently large, thereby improving the radiation effect of the antenna device.

[0046] In some embodiments, such as Figures 5 to 12 As shown, the first electrode plate 410 and the second electrode plate 420 are completely opposite to each other. Compared to a configuration where the first electrode plate 410 and the second electrode plate 420 are staggered, this configuration allows for a larger effective capacitance area, resulting in a larger capacitance value and improved radiation performance of the antenna device.

[0047] In some embodiments, such as Figures 5 to 12 As shown, the first electrode plate 410 can be arranged perpendicularly to the first reflective surface 111, and the second electrode plate 420 can be arranged perpendicularly to the second reflective surface 211, which helps to simplify the fabrication process of the coupling capacitor 400 and improve the radiation effect of the antenna device.

[0048] The direction in which the first electrode 410 extends relative to the first reflective surface 111 and the direction in which the second electrode 420 extends relative to the second reflective surface 211 can be determined based on the placement of other components and structures in the antenna device, thereby avoiding adverse effects of the first electrode 410 and the second electrode 420 on other components of the antenna device. To maximize the capacitance value of the coupling capacitor 400, the first electrode 410 and the second electrode 420 can extend in the same direction, although the embodiments of this disclosure are not limited thereto.

[0049] In some embodiments, such as Figure 5 , Figure 8 and Figure 11 As shown, the first electrode plate 410 can extend toward the front of the antenna device relative to the first reflective surface 111, and the second electrode plate 420 can extend toward the front of the antenna device relative to the second reflective surface 211.

[0050] In some embodiments, such as Figure 6 and Figure 9 As shown, the first electrode plate 410 can extend relative to the first reflective surface 111 toward the rear side of the antenna device, and the second electrode plate 420 can extend relative to the second reflective surface 211 toward the rear side of the antenna device.

[0051] In some embodiments, such as Figure 7 , Figure 10 and Figure 12 As shown, the first electrode plate 410 can extend relative to the first reflective surface 111 in both directions toward the front and rear of the antenna device, and the second electrode plate 420 can extend relative to the second reflective surface 211 in both directions toward the front and rear of the antenna device, so as to further increase the capacitance value of the coupling capacitor 400.

[0052] The first electrode plate 410 and the second electrode plate 420 can be formed in a variety of ways.

[0053] In some embodiments, such as Figures 5 to 7As shown, the first reflective component 110 may include a first conductive plate 410a disposed at an angle relative to the first reflective surface 111, the first conductive plate 410a being configured to form a first electrode plate 410; and the second reflective component 210 may include a second conductive plate 420a disposed at an angle relative to the second reflective surface 211, the second conductive plate 420a being configured to form a second electrode plate 420.

[0054] Specifically, the first electrode plate 410 can be formed by bending the first reflective component 110 relative to the first reflective plate 112 at a first angle, wherein the first reflective plate 112 is a planar plate including a first reflective surface 111; and the second electrode plate 420 can be formed by bending the second reflective component 210 relative to the second reflective plate 212 at a second angle, wherein the second reflective plate 212 is a planar plate including a second reflective surface 211. That is to say, the first reflective plate 112 can be integrally formed with the first electrode plate 410, and the second reflective plate 212 can be integrally formed with the second electrode plate 420, thereby simplifying the fabrication process of the coupling capacitor 400.

[0055] In some embodiments, the first angle can be a right angle, and the second angle can be a right angle, which helps to simplify the fabrication process of the coupling capacitor 400 and improve the radiation effect of the antenna device.

[0056] In some embodiments, the first reflective component 110 is integrally disposed within the first radome 130, and the second reflective component 210 is integrally disposed within the second radome 230. Correspondingly, the first electrode 410 and the second electrode 420 of the coupling capacitor 400 can be respectively disposed within the first radome 130 and the second radome 230. The first radome 130 and the second radome 230 will not adversely affect the coupling effect of the coupling capacitor 400, and can protect the first electrode 410 and the second electrode 420, thereby improving the radiation effect of the antenna device.

[0057] In some embodiments, such as Figures 8 to 10 As shown, the antenna device may include a first capacitor component 410b and a second capacitor component 420b. The first capacitor component 410b is a separate structure relative to the first reflector component 110, and at least a portion of the first capacitor component 410b is configured to form a first electrode 410. The second capacitor component 420b is a separate structure relative to the second reflector component 210, and at least a portion of the second capacitor component 420b is configured to form a second electrode 420.

[0058] Furthermore, the first capacitor component 410b may include a first fixing portion and a first electrode plate 410 connected to each other, wherein the first fixing portion may be configured to be mechanically connected to the first reflective component 110, and the second capacitor component 420b may include a second fixing portion and a second electrode plate 420 connected to each other, wherein the second fixing portion may be configured to be mechanically connected to the second reflective component 210.

[0059] exist Figures 8 to 10 In the specific example shown, the first fixing part may include a first fixing plate 412, wherein the first fixing plate 412 may be connected to the first reflecting component 110 parallel to the first reflecting surface 111, and the second fixing part may include a second fixing plate 422, wherein the second fixing plate 422 may be connected to the second reflecting component 210 parallel to the second reflecting surface 211.

[0060] It is understood that, in other specific examples, the first fixing part and / or the second fixing part may include screws, bolts, and other parts or components used for connection, such as clips.

[0061] Different configurations of the first plate 410 and the second plate 420 of the coupling capacitor 400 can also be combined with each other. For example... Figure 11 In the specific example shown, the first plate 410 of the coupling capacitor 400 may be a part of the first reflective member 110 formed by bending the first reflective member 110, while the second plate 420 may be formed as a part of the second capacitor member independent of the second reflective member 210.

[0062] In such Figure 12 In the specific example shown, the first electrode 410 can also be formed of two parts, wherein the first part 410c is formed by bending the first reflective member 110, and the second part 410d is formed of at least a portion of the first capacitor member independent of the first reflective member 110. Similarly, the second electrode 420 can also be formed of two parts, wherein the first part 420c is formed by bending the second reflective member 210, and the second part 420d is formed of at least a portion of the first capacitor member independent of the second reflective member 210.

[0063] It is understood that the above embodiments can also be combined in other ways, which will not be elaborated here.

[0064] According to another exemplary embodiment of this disclosure, such as Figure 13 As shown, the coupling capacitor 400 in the antenna device can be formed by the first reflective component 110 of the first antenna, the second reflective component 210 of the second antenna, and the additionally provided capacitor plate 430.

[0065] The basic structure of the first and second antennas in the antenna device can be referred to the description above, and will not be repeated here. The following will focus on the differences between this exemplary embodiment and the previously described embodiment.

[0066] The capacitor plate 430 is disposed close to the gap 300 between the first reflective component 110 and the second reflective component 210, thereby forming a coupling capacitor 400 with at least one of the first reflective component 110 and the second reflective component 210 to suppress the leakage of the signal radiated by the antenna device to the rear side of the antenna device through the gap 300.

[0067] Similarly, the capacitance value of the coupling capacitor 400 is generally determined by its structural parameters, which may specifically include the effective capacitance area and the effective capacitor spacing of the coupling capacitor 400. The effective capacitance area can be based on the plate area of ​​the capacitor plate 430, the width of the gap 300 between the first reflective component 110 and the second reflective component 210, etc., and the effective capacitor spacing can be obtained based on parameters such as the first spacing between the capacitor plate 430 and the first reflective component 110, the second spacing between the capacitor plate 430 and the second reflective component 210, etc.

[0068] In some embodiments, such as Figure 13 As shown, the capacitor plate 430 is parallel to at least one of the first reflective component 110 and the second reflective component 210, so as to maximize the capacitance value of the coupling capacitor 400 and improve the radiation effect of the antenna device.

[0069] In some embodiments, such as Figure 13 As shown, the projection of the capacitor plate 430 on the plane where the first reflector 110 and the second reflector 210 are located covers the interval 300, thereby minimizing signal leakage from the interval 300 to the rear side of the antenna device.

[0070] In some embodiments, the first reflective component 110 and a portion of the capacitor plates 430 may be disposed inside the first radome, while the second reflective component 210 and another portion of the capacitor plates 430 may be disposed inside the second radome. Furthermore, the capacitor plates 430 may be fixed to the radome by means of clips or other components.

[0071] In addition, embodiments of this disclosure may also include the following examples:

[0075] The coupling capacitor includes a first plate and a second plate, wherein the first plate is disposed on the side of the first reflective surface of the first reflective component near the gap, and the second plate is disposed on the side of the second reflective surface of the second reflective component near the gap.
