[0039] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0040] like Figure 2 and Figure 3 As shown, an ultra-wide-angle antenna structure 10 of one embodiment includes a circuit board 100, a signal antenna 200, a first director 300, and a second director 400. The signal antenna 200 is electrically connected to the signal transceiver terminal of the circuit board 100. The first director 300 and the second director 400 are respectively electrically connected to two director terminals of the circuit board 100. The first director 300, the second director 400, and the signal antenna 200 are located on the same side of the circuit board 100, and the signal antenna 200 is located between the first director 300 and the second director 400.

[0043] As Figure 2 and Figure 3 shown, in one embodiment, the first preset induction gap 500 is 0.3mm-0.6mm, and the second preset induction gap 600 is 5mm-6mm.

[0044] In this embodiment, the first preset induction gap 500 is preferably 0.4mm, and the second preset induction gap 600 is preferably 5.1mm, the first preset induction gap 500 is the horizontal distance between the first director 300 and the signal antenna 200 in the vertical plane, and the second preset induction gap 600 is the horizontal distance between the second director 400 and the signal antenna 200 in the vertical plane, by reasonably setting the first preset induction gap 500 and the second preset induction gap 600, the first director 300 and the second director 400 can better guide the electromagnetic wave of the signal antenna 200, so as to enhance the directivity and gain of the signal antenna 200, improve the detectable range of the automobile, and realize the signal transmission effect of the signal antenna 200 with ultra-wide angle.

[0045] As Figure 2 and Figure 3 shown, in one embodiment, the height of the first director 300 is 8.0mm-8.5mm, the height of the signal antenna 200 is 5.0mm-5.5mm, and the height of the second director 400 is 3.0mm-3.5mm.

[0046] In this embodiment, the height of the first director 300 is preferably 8.4mm, the height of the signal antenna 200 is preferably 5.4mm, and the height of the second director 400 is preferably 3.4mm, so that the heights of the first director 300, the signal antenna 200 and the second director 400 decrease in turn, and the current between the first director 300, the signal antenna 200 and the second director 400 is adjusted through the heights of the first director 300, the signal antenna 200 and the second director 400, so that the current of the first director 300 and the second director 400 and the current of the signal antenna 200 exist a phase difference, due to the existence of the phase difference, the first director 300 and the second director 400 generate a positive induced electromotive force, the positive induced electromotive force can enhance the radiation power outputted by the antenna to the front, so that the antenna pattern is inclined to the direction of the first director 300 and the second director 400, and the directivity and gain of the signal antenna 200 are improved.

[0047] As Figure 2 and Figure 3As shown, in one of the embodiments, the first director 300 comprises a first director piece 310 and three first connecting columns 320, one end of each of the first connecting columns 320 is connected with the circuit board 100, one end of two of the first connecting columns 320 is respectively connected to the opposite sides of the first director piece 310, and one end of the other first connecting column 320 is connected to the side of the first director piece 310 away from the signal antenna 200, so that the three first connecting columns 320 are in triangular distribution. In this embodiment, the first director piece 310 is fixed by the three first connecting columns 320, the first director piece 310 guides the electromagnetic waves of the signal antenna 200, and the three first connecting columns 320 are respectively connected to the sides of the first director piece 310, so that the three first connecting columns 320 are in triangular distribution. It can be understood that the car will shake during driving, especially when encountering poor road conditions, the shaking will be more intense. By designing the three first connecting columns 320 in triangular distribution, the use of less material reduces the cost, and at the same time, the support and fixing effect of the first connecting column 320 on the first director piece 310 is better, which slows down the shaking of the first director 300 during driving, thereby ensuring the accuracy of the signal guiding and transmission of the first director 300. Further, one of the first connecting columns 320 is connected to the side of the first director piece 310 away from the signal antenna 200, that is, the side of the first director piece 310 adjacent to the signal antenna 200 is not provided with the first connecting column 320, so that the side of the first director piece 310 adjacent to the signal antenna 200 is not blocked by the first connecting column 320, so that the support is stable while the guiding and transmission effect of the first director piece 310 on the signal antenna 200 is better.

In this embodiment, the second director piece 410 is fixed by the three second connecting columns 420, the second director piece 410 guides the electromagnetic waves of the signal antenna 200, and the three second connecting columns 420 are respectively connected to the sides of the second director piece 410, so that the three second connecting columns 420 are in a triangular distribution. It can be understood that the car will shake during driving, especially when encountering poor road conditions, the shaking will be more intense. By designing the three second connecting columns 420 in a triangular distribution, the use of less material reduces the cost, and at the same time, the second connecting column 420 has a better supporting and fixing effect on the second director piece 410, thereby slowing down the shaking of the second director 400 during driving, thereby ensuring the accuracy of the signal guiding and transmission of the second director 400. Further, one of the second connecting columns 420 is connected to the side of the second director piece 410 away from the signal antenna 200, that is, the side of the second director piece 410 adjacent to the signal antenna 200 is not provided with a second connecting column 420, so that the side of the second director piece 410 adjacent to the signal antenna 200 is not blocked by the second connecting column 420, so that the supporting stability is ensured, and at the same time, the guiding and transmission effect of the second director piece 410 on the signal antenna 200 is better.

[0049] As Figure 2 and Figure 3As shown in the drawings, in one embodiment, the first guide 310 is provided with two arc-shaped guide portions 330 adjacent to both ends of one side of the signal antenna 200, the two arc-shaped guide portions 330 are symmetrically arranged relative to the signal antenna 200, and the signal antenna 200 is located between the two arc-shaped guide portions 330 in the vertical direction. In this embodiment, the second guide 410 is used to guide the signal transmission of the signal antenna 200, and the second guide 410 is provided with two arc-shaped guide portions 330 adjacent to both ends of one side of the signal antenna 200. The arc-shaped guide portions 330 make the electromagnetic wave of the signal antenna 200 more uniform. Further, the signal antenna 200 is located between the two arc-shaped guide portions 330 in the vertical direction, that is, in the top view or bottom view, the signal antenna 200 is located between the two arc-shaped guide portions 330, and the two arc-shaped guide portions 330 are symmetrically arranged relative to the signal antenna 200. The electromagnetic wave of the signal antenna 200 is guided under the two arc-shaped guide portions 330, so that the electromagnetic wave on both sides of the second guide 400 is more uniform, and the gain of the signal antenna 200 in the direction of the second guide 400 is further improved.

[0050] As shown in the drawings, Figure 2 In one embodiment, the signal antenna 200 includes a conductive member 210, a first antenna body 220, and a second antenna body 230.

In this embodiment, the conductive member 210, the first antenna body 220, and the second antenna body 230 are sequentially connected. The conductive member 210 is electrically connected to the circuit board 100. The first antenna body 220 and the second antenna body 230 generate electromagnetic waves when working. There is a preset angle between the first antenna body 220 and the second antenna body 230. The second antenna body 230 is arranged adjacent to the first guide 310, so that the electromagnetic wave signal in the direction of the first guide 310 is more intense, to adapt to the driving environment of the vehicle. Further, the first antenna body 220, the first guide 310, and the second guide 410 are arranged in parallel, so that the width between the first antenna body 220 and the first guide 310 and the second guide 410, that is, the first preset induction gap 500 and the second preset induction gap 600, remains a stable value, so that the electromagnetic wave radiation through the first preset induction gap 500 and the second preset induction gap 600 is more uniform.

[0051] As shown in the drawings, Figure 2As shown in the drawings, in one embodiment, the preset angle between the first antenna body 220 and the second antenna body 230 is 90°. In this embodiment, the preset angle between the first antenna body 220 and the second antenna body 230 is 90°, that is, the first antenna body 220 and the second antenna body 230 are perpendicular to each other, that is, the second antenna body 230 is also arranged vertically with the first director 310, so that the electromagnetic wave signal of the second antenna body 230 is guided and transmitted through the first director 310, further enhancing the directivity and gain of the signal antenna 200, improving the detectable range of the automobile, and thus realizing the super-wide-angle signal transmission effect of the signal antenna 200.

[0054] 2. The gain of the super-wide-angle antenna structure of the above embodiment is also distributed in 90°-150°, 210°-270°, that is, the gain range of the super-wide-angle antenna structure is large, which can reach 250°, so that the automobile can realize the super-wide-angle signal transmission effect and improve the detectable range of the automobile.

[0055] Further, as shown in the drawings, Figure 8 the curve shows the change of the S parameter (amplitude) of the super-wide-angle antenna structure at different frequencies. When the frequency of the antenna is 5.85 GHz, the amplitude of the S parameter is -15.2241 dB, and when the frequency of the antenna is 5.9 GHz, the amplitude of the S parameter is -17.51838 dB, that is, the amplitude of the S parameter is lower than -10 dB in this frequency interval, indicating that most of the input signals are effectively received and radiated by the antenna, rather than being reflected back, so that the automobile can realize the super-wide-angle signal transmission effect and improve the detectable range of the automobile.
