The waveguide structure 100 comprises a first waveguide 1 and a second waveguide 2; the first waveguide 1 intersects with the second waveguide 2; the first waveguide 1 comprises an inlet end 3, and the second waveguide 2 comprises an outlet end 4, wherein a signal passes through the inlet end 3 and is outlet from the outlet end 4; at least one step 11 is provided at one end of the first waveguide 1 corresponding to the outlet end 4; at least one groove is also provided on the first waveguide 1, at least a portion of the at least one groove is located on the step 11, and the groove is used to improve the transmission efficiency of the signal.

[0036] The embodiment of the utility model provides a waveguide structure 100, which includes a first waveguide 1 and a second waveguide 2. By arranging a step portion 11 on the first waveguide 1 and opening a groove in the step portion 11, the signal transmission efficiency of the waveguide structure 100 is improved.

[0037] In the embodiment of the present application, intersection refers to the connection between the first waveguide 1 and the second waveguide 2, and the connection between the first waveguide 1 and the second waveguide 2 is at a certain angle, and does not include overlap or straight line connection. The signal may refer to an electromagnetic wave signal, an optical wave signal or a microwave signal transmitted through the waveguide structure 100.

[0038] In the embodiment of the present application, the waveguide structure 100 is provided with the step portion 11 and the groove so that when the signal is transmitted in the waveguide structure 100, it is reflected and / or refracted by the inner wall of the groove, thereby improving the coupling efficiency of the waveguide structure 100 and thus improving the transmission efficiency of the signal.

[0039] In some embodiments, see Figure 1 and Figure 2, the first waveguide 1 is perpendicular to the second waveguide 2. When the first waveguide 1 is perpendicular to the second waveguide 2, the coupling degree of the waveguide structure 100 is very good, and the signal transmission efficiency is higher.

[0040] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 , at least one groove is provided at the middle position of one end of the first waveguide 1 corresponding to the introduction end 3. Providing the groove at the middle position of the other end of the first waveguide 1 corresponding to the introduction end 3 can make the signal better reflected and refracted when transmitted in the waveguide structure 100, further improving the coupling degree of the waveguide structure 100 and the transmission efficiency of the signal.

[0041] In the embodiment of the present application, the middle position may refer to the position in the middle of the end corresponding to the introduction end 3 on the first waveguide 1. For example, the distances between the two ends of the groove in the length direction and the two sides of the end are the same, that is, when the groove is a rectangular groove, the distances between the center point of the groove and the two sides of the end are the same, wherein the end is the end corresponding to the introduction end 3 on the first waveguide 1.

[0042] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The first waveguide 1 includes a step portion 11 and a groove; the groove is located on the step portion 11. The reflection and refraction effects of the signal when transmitted in the waveguide structure 100 can be further improved, and the coupling degree of the waveguide structure 100 and the transmission efficiency of the signal can be further improved.

[0043] In the embodiment of the present application, the length of the step portion 11 on the first waveguide 1 is the same as the length of the introduction end 3 of the first waveguide 1, that is, the same as the length of the end corresponding to the introduction end 3. The groove can be set to a regular or irregular shape. For example, the groove can be set to a rectangular, circular, triangular or polygonal shape, or it can be set to a shape of a whole stacked with several cuboids of different sizes.

[0044] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The first waveguide 1 includes a first step portion 111 and a second step portion 112; at least one groove is located on the second step portion 112. The second step portion 112 is closer to the middle position than the first step portion 111, which can better ensure the refraction and reflection effects during signal transmission, thereby further improving the coupling effect of the waveguide structure 100 and the transmission efficiency of the signal.

[0045] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The waveguide structure 100 also includes a third step portion 113, and a first groove 12, a second groove 13 and a third groove 14; wherein the first groove 12 is opened on the second step portion 112, and the third groove 14 is opened on the third step portion 113; a part of the second groove 13 is located on the second step portion 112, and the other part is located on the third step portion 113; the third groove 14 is connected to the first groove 12 through the second groove 13.

[0046] In the embodiment of the present application, the third step portion 113 is closest to the signal output terminal 4, the first step portion 111 is farthest from the output terminal 4, and the second step portion 112 is located between the first step portion 111 and the second step portion 112; that is, the third groove 14 is closer to the output terminal 4, and the first groove 12 is farther from the output terminal 4. Through the structural arrangement of the first step portion 111, the second step portion 112 and the third step portion 113 of the waveguide structure 100, and the distribution positions of the first groove 12, the second groove 13 and the third groove 14 on the second step portion 112 and the third step portion 113, the signal enters the waveguide structure 100 from the introduction end 3, passes through the first step portion 111, the second step portion 112 and the first groove 12, the second groove 13 and the third step portion 113 and the third groove 14 in sequence, and is reflected or refracted when passing through the above structures, and finally output from the output end 4, so that the coupling efficiency of the waveguide structure 100 is better, thereby greatly improving the transmission efficiency of the signal when it is transmitted in the waveguide structure 100. It is conducive to the realization of the index of waveguide conversion of the waveguide structure 100, that is, it is easy to simulate the index to meet the high performance requirements, and can be applied to the high-performance realization of the waveguide structure 100 with high requirements.

[0047] In some embodiments, the import end 3 may be a standard waveguide port, the export end 4 may be a non-standard waveguide port, and the interior of the first waveguide 1 and the second waveguide 2 may be a cavity for transmitting signals.

[0048] In some embodiments, see Figure 1 and Figure 2, the length of the first groove 12 along the first direction X is greater than the length of the second groove 13 and the third groove 14, and the lengths of the second groove 13 and the third groove 14 are the same; the width of the first groove 12 along the second direction Y is the same as the width of the second groove 13; the height of the second groove 13 along the third direction Z is greater than the height of the third groove 14; wherein the first direction X and the third direction Z are respectively perpendicular to the second direction Y, and the first direction X is perpendicular to the third direction Z. The opening positions and volumes of the first groove 12, the second groove 13 and the third groove 14 are different, and the first groove 12, the second groove 13 and the third groove 14 are connected, so that in the process of signal transmission, the direction and angle of reflection and refraction can have more choices, thereby making the coupling efficiency of the waveguide structure 100 better, and the transmission efficiency of the signal when transmitted in the waveguide structure 100 is greatly improved.

[0049] In some embodiments, the first direction X is the length direction, the second direction Y is the width direction, and the third direction Z is the height direction. The width of the first step portion 111 is 5.00mm-6.00mm; the width of the second step portion 112 is 2.50mm-3.00mm; the width of the third step portion 113 is 3.00mm-4.50mm. The length of the first groove 12 is 7.00mm-7.20mm, the width is 1.9mm-2.09mm, and the height is 2.10mm-2.21mm. The length of the second groove 13 is 3.5mm-3.7mm, the width is 1.9mm-2.09mm, and the height is 2.50mm-2.70mm. The length of the third groove 14 is 3.5mm-3.7mm, the width is 2.00mm-2.30mm, and the height is 2.20mm-2.49mm.

[0050] In some embodiments, the width of the first waveguide 1 along the second direction Y (ie, the width direction) is 12 mm, wherein the width of the first step portion 111 is 5.17 mm; the width of the second step portion 112 is 2.71 mm; and the width of the third step portion 113 is 4.12 mm.

[0051] In some embodiments, the first groove 12 has a length of 7.12 mm, a width of 2.00 mm, and a height of 2.20 mm. The second groove 13 has a length of 3.64 mm, a width of 2.00 mm, and a height of 2.65 mm. The third groove 14 has a length of 3.64 mm, a width of 2.10 mm, and a height of 2.23 mm.

[0052] In some embodiments, through the design of the waveguide structure 100, the waveguide structure 100 is designed to be a matching form of opening three rectangular grooves (i.e., the first groove 12, the second groove 13, and the third groove 14) on the step portion 11. When the model is established, only the length, width, and height of the three rectangular grooves need to be adjusted to perform effective simulation. The simulation design can be applied to the realization of high-performance requirements of the waveguide structure 100.

[0053] In some embodiments, see Figure 1 and Figure 2 , the second groove 13 is perpendicular to the first groove 12 and parallel to the third groove 14. Therefore, in the process of signal transmission, there are more options for the direction and angle of reflection and refraction, thereby further improving the coupling efficiency of the waveguide structure 100 and the transmission efficiency of the signal when it is transmitted in the waveguide structure 100.

[0054] In some embodiments, see Figure 6 , Figure 6 The simulation performance curve of the waveguide structure in the embodiment of the utility model is shown. Figure 6 The horizontal axis is the frequency in gigahertz (GHz); the vertical axis is the echo index in dB. Figure 6 It can be concluded that in the frequency range of 6.5GHz-9.0GHz, the echo index is between -30dB and -40dB, and the loss is only about -0.002dB. Figure 5 , Figure 5 The simulation performance curve of the waveguide structure in the related art is shown. When the frequency range is 6.5GHz-9.0GHz, the echo index is only between -20dB and -25dB, while the loss is around -0.01dB. When the frequency of the waveguide structure in the related art is 7.9GHz, the simulation index reaches the maximum value, close to -20dB; while in the embodiment of the present application, when the frequency of the waveguide structure 100 is 7.9GHz, the value of the simulation index is close to -30dB. The waveguide structure 100 in the embodiment of the present application is not only easy to simulate the high performance requirements, but also the loss is significantly reduced. It can be seen that the simulation performance of the waveguide structure 100 in the embodiment of the present application is greatly improved relative to the waveguide structure in the related art.

It is conducive to the realization of the index of waveguide conversion, that is, it is easy to simulate the index to achieve high performance requirements, and can be applied to the high-performance realization of the waveguide device 200 with high requirements. That is, the coupling efficiency of the waveguide device 200 can be improved, and then the transmission efficiency of the signal when it is transmitted in the waveguide device 200 can also be improved. Exemplarily, the waveguide device 200 in the embodiment of the present application can achieve an echo index of about -30dB, and the loss is only about -0.002dB; compared with the echo index of about -21dB in the related art, and the loss is about -0.01dB, the performance of the waveguide device 200 in the embodiment of the present application is greatly improved.
