[0016] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0018] See also Figures 1 to 3 The present application provides a gateway device 20 , which includes a housing 211 and an antenna 10 .

[0019] The shell 211 is provided with an arc-shaped mounting surface 2111, and the antenna 10 includes a radiator 11, which is arranged in an arc shape and has the same curvature as the arc-shaped mounting surface 2111. The radiator 11 includes a first end 111 and a second end 112 opposite to each other, and the first end 111 and the second end 112 are both attached to the arc-shaped mounting surface 2111. The radiator 11 is provided with a hollow portion 113, and the hollow portion 113 is located between the first end 111 and the second end 112.

[0020] The gateway device 20 provided in the embodiment of the present application, by setting the radiator 11 in an arc shape and making it consistent with the curvature of the arc-shaped mounting surface 2111, the radiator 11 and the arc-shaped mounting surface 2111 have a higher fit, and at the same time, a hollow portion 113 is set between the two ends of the radiator 11, which can reduce the stress of the radiator 11, so that the first end 111 and the second end 112 are not easy to warp when they are attached to the arc-shaped mounting surface 2111, and the installation shape of the radiator 11 when it is installed on the arc-shaped mounting surface 2111 is effectively maintained, thereby ensuring the radiation efficiency and gain of the radiator 11.

[0021] See also Figure 1 and Figure 2 In this embodiment, the housing 211 may be a plastic structure. The housing 211 includes a top housing 211 and a bottom housing 212. The top housing 211 is covered on the bottom housing 212. The top housing 211 and the bottom housing 212 define a mounting cavity 213 together. The mounting cavity 213 is used to mount circuit components such as circuit boards. In this embodiment, the top housing 211 may be a mushroom-shaped or hemispherical housing. The arc-shaped mounting surface 2111 is located inside the top housing 211. The arc-shaped mounting surface 2111 may be understood as a busbar M formed by a circle around the axis O. The axis O may be the center line of the top housing 211. The busbar M may be a circular arc, an elliptical arc, or an arc of other shapes. In addition, the arc-shaped mounting surface 2111 may also be an arc surface of other regular or irregular shapes. For example, the busbar M may include multiple segments of circular arcs connected in sequence. For example, the busbar M may be a wavy line. The arc-shaped mounting surface 2111 may be formed by a wavy line around the axis O.

[0022] In this embodiment, the gateway device 20 includes a circuit board 22, and the circuit board 22 is electrically connected to the radiator 11. The circuit board 22 can be electrically connected to the radiator 11 through a feeder structure, or can be electrically connected through a conductive structure inside the housing 211. The circuit board 22 is installed in the installation cavity 213, and can be fixed to the top shell 211 or the bottom shell 212. For example, the circuit board 22 can be installed in the top shell 211 and corresponds to the middle position of the top shell 211. It can be spaced apart from the radiator 11. In addition, in some embodiments, the circuit board 22 can be fixed on the arc-shaped mounting surface 2111 by a mounting structure, the mounting structure can be a fixing column, the circuit board 22 can be locked on the arc-shaped mounting surface 2111 by a fastener, a clamping gap is formed between the circuit board 22 and the arc-shaped mounting surface 2111, the radiator 11 is attached to the arc-shaped mounting surface 2111, and the first end 111 and the second end 122 of the radiator 11 can be respectively embedded in the clamping gap, so that the circuit board 22 can press the first end 111 and the second end 122 against the arc-shaped mounting surface 2111, further avoiding the warping of the two ends of the radiator 11. Further, the clamping gap between the circuit board 22 and the arc-shaped mounting surface 2111 can be formed by manufacturing error or installation error. In addition, part of the structure of the circuit board 22 is a non-circuit structure, that is, part of the structure of the circuit board 22 is not provided with circuits and electronic components, and a clamping gap is formed between the non-circuit structure and the arc-shaped mounting surface 2111, so that the non-circuit structure will not interfere with the signal transmission and reception of the radiator 11.

[0023] In this embodiment, the radiator 11 can be attached to a partial area or the entire area of ​​the arc-shaped mounting surface 2111, and can be specifically set according to actual needs. The radiator 11 can be a flexible structure, specifically, it can be a flexible sheet structure. When the radiator 11 is attached to the top shell 211, it can deform to bend to form an arc-shaped structure, so as to adapt to the curvature of the arc-shaped mounting surface 2111. The radiator 11 can fully fit with the installation area of ​​the arc-shaped mounting surface 2111 by its own deformation. After the radiator 11 is bonded to the arc-shaped mounting surface 2111, since the two ends of the radiator 11 are not easy to warp, the radiator 11 can maintain the shape after installation, so that the radiator 11 can maintain better radiation performance.

[0024] In other embodiments, the radiator 11 itself can also be set as an arc-shaped structure, and the curvature of the radiator 11 itself is substantially consistent with the curvature of the to-be-installed area of ​​the arc-shaped installation surface 2111. When the radiator 11 is installed on the arc-shaped installation surface 2111, it can be completely fitted with the arc-shaped installation surface 2111. By directly installing the radiator 11 on the wall surface of the top shell 211, there is no need to set a separate installation structure, and the radiator 11 only needs to be fitted on the top shell 211, which is easy to install, and the radiator 11 can be separated from the circuit components in the installation cavity 213 as much as possible, effectively ensuring the radiation efficiency of the radiator 11.

[0025] In some embodiments, Figure 2 As shown, the curvature of the arc-shaped mounting surface 2111 near the edge of the top shell 211 is smaller than the curvature of the arc-shaped mounting surface 2111 away from the edge of the top shell 211. It can be understood that the curvature of the arc-shaped mounting surface 2111 is not uniform everywhere. The curvature of the arc-shaped mounting surface 2111 can be gradually reduced from its top to its edge, and the radiator 11 is attached to the area of ​​the arc-shaped mounting surface 2111 near the edge of the top shell 211. By attaching the radiator 11 to the area with a smaller curvature of the arc-shaped mounting surface 2111, the deformation of the radiator 11 can be appropriately reduced, thereby reducing the warping force of the radiator 11 attached to the arc-shaped mounting surface 2111, which is conducive to ensuring the fit of the radiator 11 on the arc-shaped mounting surface 2111, maintaining the installation form of the radiator 11 when it is installed on the arc-shaped mounting surface 2111, thereby ensuring the radiation efficiency and gain of the radiator 11.

[0026] In some embodiments, the radiator 11 may also be disposed at the top of the arc-shaped mounting surface 2111 so that the distance between the radiator 11 and the bottom shell 212 is larger, which is beneficial for separating the radiator 11 from the circuit devices on the bottom shell 212 and avoiding interference with the circuit devices.

[0027] In this embodiment, the radiator 11 includes an upper surface 1111 and a lower surface 1112. The upper surface 1111 and the lower surface 1112 are respectively located in the thickness direction of the radiator 11. The upper surface 1111 is attached to the arc-shaped mounting surface 2111. Both the upper surface 1111 and the lower surface 1112 can be arc-shaped surfaces. The curvature of the upper surface 1111 can be consistent with the curvature of the area to be attached on the arc-shaped mounting surface 2111, so that the upper surface 1111 can be entirely attached to the arc-shaped mounting surface 2111, ensuring the fit of the radiator 11 on the arc-shaped mounting surface 2111. Specifically, the upper surface 1111 can be bonded to the arc-shaped mounting surface 2111.

[0028] In this embodiment, the radiator 11 may be roughly a strip-shaped structure, and the first end 111 and the second end 112 may be the two ends of the radiator 11 along its length direction, respectively. The first end 111 and the second end 112 may be bent toward the same side of the radiator 11, and both may be bent at a small angle, so that the radiator 11 forms a slightly arched arc structure, so that the upper surface 1111 of the radiator 11 is fitted with the arc-shaped mounting surface 2111. It should be noted that the first end 111 and the second end 112 refer to any two opposite partial structures on the radiator 11. For example, when the radiator 11 is a circular sheet structure, the first end 111 and the second end 112 may be the two ends of the radiator 11 in the radial direction; for another example, when the radiator 11 is an elliptical sheet structure, the first end 111 and the second end 112 may be the two ends of the long axis direction or the short axis direction of the radiator 11. The length of the radiator 11 may be 1 / 4 of the wavelength of the radiation signal, and the specific length of the radiator 11 may be adjusted as needed.

[0029] In some embodiments, Figure 3 He Ru Figure 4 As shown, the hollow portion 113 is provided on the lower surface 1112, and the hollow portion 113 is substantially extended along the width direction of the radiator 11. Exemplarily, the hollow portion 113 may include a slit 1131 on the lower surface 1112, the depth of the slit 1131 is less than the thickness of the radiator 11, the slit 1131 may be provided along the width direction of the radiator 11, and the length of the slit 1131 may be less than or equal to the width of the radiator 11. By providing the slit 1131 between the first end 111 and the second end 112, the stress generated when the first end 111 and the second end 112 are bent can be reduced, so that when the radiator 11 is attached to the arc-shaped mounting surface 2111, the first end 111 and the second end 112 are not easy to warp.

[0030] In some embodiments, Figure 3 and Figure 4As shown, the radiator 11 further includes a first side surface 1113 and a second side surface 1114 in the width direction, the first side surface 1113 and the second side surface 1114 are connected between the upper surface 1111 and the lower surface 1112, and the hollow portion 113 passes through the first side surface 1113 and the second side surface 1114. Specifically, the gap 1131 can pass through the first side surface 1113 and the second side surface 1114. When the radiator 11 is bonded, it is easier to bend and deform under the action of the bending force to deform to an arc that matches the arc-shaped mounting surface 2111, and the gap 1131 can reduce the stress between the two side surfaces, and further reduce the stress between the first end 111 and the second end 112. Therefore, when the first end 111 and the second end 112 are bonded to the arc-shaped mounting surface 2111, the two ends of the radiator 11 are not easy to warp, and the entire radiator 11 can be firmly bonded to the arc-shaped mounting surface 2111 and maintain its normal shape after bonding, thereby ensuring its radiation efficiency.

[0031] In some embodiments, the depth of the gap 1131 is less than the thickness of the radiator 11, and the gap 1131 can be provided on the lower surface 1112, but does not penetrate the upper surface 1111. In this way, the two ends of the radiator 11 are still connected through the partial structure located in the gap 1131, so as to ensure the connection strength of the entire radiator 11 structure. In this way, under the premise of reducing the stress of the radiator 11, the first end 111 and the second end 112 of the radiator 11 are also connected, and the two ends of the radiator 11 can be electrically connected through the connected part, so that the radiator 11 can still be used as a radiating structure to send and receive signals, thereby ensuring the radiation efficiency of the radiator 11. In addition, when the first end 111 and the second end 112 are respectively used as separate radiation units, the two can increase the isolation between each other through the gap 1131 to reduce the interference between the two. It should be noted that the gap 1131 can be curved or straight, and can be set according to actual needs.

[0032] In some embodiments, Figure 5As shown, the hollow portion 113 may include a first slit 1131a and a second slit 1131b, and the first slit 1131a and the second slit 1131b may be extended in two different directions. For example, the first slit 1131a and the second slit 1131b are intersected, and the first slit 1131a may be arranged along the width direction of the radiator 11, and the second slit 1131b may be arranged along the length direction of the radiator 11. In this way, the stress on the radiator 11 in different directions can be reduced, and the end of the radiator 11 can be effectively prevented from warping. In other embodiments, the first slit 1131a and the second slit 1131b may also be arranged along the diagonal direction of the radiator 11, respectively. In addition, when the radiator 11 is a circular sheet structure, the first slit 1131a and the second slit 1131b may be arranged along two different radial directions of the radiator 11, respectively.

[0033] In some embodiments, Figure 6 As shown, the hollow portion 113 includes a plurality of grooves 1133, and the plurality of grooves 1133 are arranged at intervals at the connection between the first end 111 and the second end 112. Exemplarily, the plurality of grooves 1133 may be blind grooves or through groove structures, and the plurality of grooves 1133 may be arranged side by side and at intervals. For example, the plurality of grooves 1133 may be through groove structures, which penetrate the upper surface 1111 and the lower surface 1112 of the radiator 11, and the plurality of grooves 1133 may be arranged side by side and at intervals substantially along the width direction of the radiator 11. By providing a plurality of grooves 1133, the stress at the connection between the first end 111 and the second end 112 may be reduced, so that not only the connection strength between the first end 111 and the second end 112 can be ensured, but also the radiator 11 attached to the arc-shaped mounting surface 2111 is not prone to warping, so that the radiator 11 is maintained in a normal shape.

[0034] In some embodiments, Figure 7 As shown, the radiator 11 is provided with a flexible connection layer 115, the flexible connection layer 115 is connected to the entire upper surface 1111, and the flexible connection layer 115 is bonded to the arc-shaped mounting surface 2111. It should be noted that the flexible connection layer 115 can be a foam layer, a rubber layer or a silicone layer. By providing the flexible connection layer 115, the connection strength between the first end 111 and the second end 112 can be increased to prevent the first end 111 and the second end 112 from breaking when the first end 111 and the second end 112 are relatively bent. At the same time, the radiator 11 can adapt to the arc-shaped mounting surface 2111 by utilizing the deformation of the flexible connection layer 115 itself, so that the curvature of the radiator 11 itself can be reduced, and the end of the radiator 11 can be further prevented from warping.

[0035] See also Figure 8In this embodiment, the first end 111 is provided with a first feeding position 1114, and the second end 112 is provided with a second feeding position 1124. The first feeding position 1114 and the second feeding position 1124 are located on opposite sides of the hollow portion 113. The antenna 10 includes a feeder 12, and the feeder 12 is connected to the first feeding position 1114 and the second feeding position 1124 to feed an excitation signal to the first end 111 and the second end 112. One end of the feeder 12 can be fixed to the first feeding position 1114 and the second feeding position 1124 by welding, and the other end is connected to the circuit board. The feeder 12 can feed an excitation signal to the first end 111 and the second end 112 at the same time. The first end 111 and the second end 112 can be used as the same radiation unit, and the two are used to send and receive the same signal. In this way, the dual transmission and dual reception of the signal of the radiator 11 can be realized. For example, the radiator 11 can be used to send and receive Wi-Fi signals, Zigbee signals, etc.

[0036] In some embodiments, Figure 8 As shown, the first side surface 1113 and the second side surface 1114 are arranged in an arc shape, and the radiator 11 can be approximately a crescent-shaped structure, and the first side surface 1113 and the second side surface 1114 are both bent toward the same side of the radiator 11. By arranging the first side surface 1113 and the second side surface 1114 in an arc shape, it is beneficial to increase the equivalent current path of the radiator 11, thereby increasing the radiation efficiency and radiation range of the radiator 11. In addition, by arranging the first side surface 1113 in an arc shape, the first side surface can be arranged along the arc edge of the arc-shaped mounting surface 2111, which is beneficial to arrange the radiator 11 close to the edge of the arc-shaped mounting surface 2111 with a smaller curvature.

[0037] In some embodiments, the number of radiators 11 may be two or more, and the two or more radiators 11 may be arranged at intervals around the center line of the top case 211. In addition, the number of radiators 11 may be single, and a single radiator 11 may be arranged around the center line of the top case 211, and may be arranged around 1 / 10 of the edge of the arc-shaped mounting surface 2111, or may be arranged around 1 / 2 or more of the edge of the arc-shaped mounting surface 2111, and the specific arrangement may be adjusted according to actual needs.

[0038] In some embodiments, Figure 8As shown, the arc length X1 of the first side 1113 and the second side 1114 can be greater than or equal to 49.0 mm and less than or equal to 49.8 mm. Further, the arc length X1 of the first side 1113 and the second side 1114 can be greater than or equal to 49.2 mm and less than or equal to 49.6 mm. For example, the arc length X1 of the first side 1113 and the second side 1114 can be 49.2 mm, 49.4 mm or 49.6 mm. In addition, there is a maximum width dimension X2 between the first side surface 1113 and the second side surface 1114, and the maximum width dimension X2 may be greater than or equal to 13.0 mm and less than or equal to 14.0 mm. Further, the maximum width dimension between the first side surface 1113 and the second side surface 1114 may be greater than or equal to 13.2 mm and less than or equal to 13.7 mm. For example, the maximum width dimension between the first side surface 1113 and the second side surface 1114 may be 13.2 mm, 13.4 mm, 13.6 mm, or 13.7 mm, wherein the maximum width dimension may be the distance between the top tangent line of the first side surface 1113 and the point on the second side surface 1114 farthest from the first side surface 1113. By controlling the arc length of the first side surface 1113 and the second side surface 1114 to be between 49.0 mm and 49.7 mm, and controlling the maximum width dimension between the first side surface 1113 and the second side surface 1114 to be between 13.0 mm and 14.0 mm, the radiation efficiency and gain of the radiator 11 may be effectively improved.

[0039] In some embodiments, the length of the feeder 12 of the gateway device 20 may be greater than or equal to 65.0 mm and less than or equal to 66.0 mm. Further, the length of the feeder 12 may be greater than or equal to 65.2 mm and less than or equal to 65.33 mm. By controlling the feeder 12 of the gateway device 20 within a reasonable length range, the return loss of the feeder 12 may be controlled within a lower range, thereby effectively reducing the influence of the feeder 12 on the radiation efficiency of the radiator 11, so as to further improve the radiation efficiency of the radiator 11.

[0040] The gateway device 20 provided in the embodiment of the present application sets the radiator 11 in an arc shape and makes it consistent with the curvature of the arc-shaped mounting surface 2111, so that the fit between the radiator 11 and the arc-shaped mounting surface 2111 is higher, and at the same time, a hollow portion 113 is set between the two ends of the radiator 11, which can reduce the stress of the radiator 11, so that the first end 111 and the second end 112 are not easy to warp when they are attached to the arc-shaped mounting surface 2111, and the installation shape of the radiator 11 when it is installed on the arc-shaped mounting surface 2111 is maintained, thereby ensuring the radiation efficiency and gain of the radiator 11, and the fit between the optimized radiator 11 and the arc-shaped mounting surface 2111 is significantly improved. After the radiator 11 is bonded to the arc-shaped mounting surface 2111 and left to stand for more than 48 hours, the radiator 11 does not show any warping phenomenon, and the overall efficiency of the optimized antenna 10 is improved by more than 15%.

[0041] Please refer to Table 1 and Table 2 below. Table 1 below shows the gain and radiation efficiency of an existing gateway device (unimproved) at different frequencies. Table 2 below shows the gain and radiation efficiency of the gateway device 20 provided in the embodiment of the present application at different frequencies. Combining Table 1 and Table 2 below, it can be clearly seen that the embodiment of the present application sets a hollow portion 113 between the two ends of the radiator 11 and controls the gateway device 20 within the above optimized size. Obviously, compared with the existing gateway device, the gain and radiation efficiency of the improved gateway device 20 within 2400Mhz~2500Mhz are significantly improved. Combined with Fig. 9 ,curve Figure 1 1 is a curve diagram of the return loss (i.e., return loss) of the gateway device 20, which is the reflection caused by the impedance mismatch of the feeder 12 or the part of the feeder 12 connected to the radiator. The smaller the reflection, the better the quality. By controlling the length of the feeder 12 within the above-mentioned length range, and connecting the feeder 12 to the first feeding position 1114 and the second feeding position 1124 of the radiator 11, it is obvious from the curve Figure 1 It can be seen from the curve that the log of the optimized gateway device at debugging position 1, 2, and 3 is less than -10, indicating that the return loss of the gateway device is low. Figure 2 The Smith chart of the gateway device 20 shows that the gateway device 20 can perform impedance matching more quickly. The center of the circle is the matching point of the gateway device 20. The upper half of the circle is the inductive reactance, and the imaginary part is positive; the lower half is the capacitive reactance, and the imaginary part is negative. It is the matching value adjusted according to the direction of the set frequency point in the circuit based on the principle of inductance and capacitance characteristics. The curve Figure 2 It can be shown that the impedance performance of the improved gateway device 20 meets the impedance matching requirements of the antenna. Figure 3This is a curve of the standing wave ratio (SWR) of the gateway device, where the standing wave ratio is the impedance mismatch between the radiator and the feeder or the impedance mismatch between the antenna and the transmitter (i.e., the radio transmitter). The high-frequency energy will be reflected and folded back, and merge with the forward interference to generate standing waves. Figure 3 It can be seen that the SWR of the gateway device 20 at the debugging positions 1, 2, and 3 is less than 3.0, and it is obvious that the standing wave of the gateway device is significantly improved.
