Summary of the Invention

[0005] However, since the directivity of a passive metasurface is determined by design, in order to change the beam direction after installation, it was necessary to mechanically move the metasurface. Further, when the metasurface is installed outdoors, a housing is required due to weather resistance and installation attachment, etc., but since the housing is fixed to the structure, it was difficult to change the beam direction after installation.

[0006] In view of the above problems, an object of the present disclosure is to provide a radio wave control device capable of easily adjusting the angle of a radio wave control board and a housing for a radio wave control board.

[0007] To solve the above-mentioned problems and achieve the objective, the radio wave control device according to this disclosure comprises a radio wave control plate that reflects or refracts radio waves, a first housing that houses the radio wave control plate, and a second housing that houses the first housing, wherein the first housing and the second housing constitute a housing for the radio wave control plate, and the first housing is rotatable in the in-plane direction relative to the second housing.

[0008] According to this disclosure, it is possible to provide a radio wave control device that allows for easy adjustment of the angle of the radio wave control plate, and a housing for the radio wave control plate. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0010] Embodiments of this disclosure will be described in detail below with reference to the drawings. However, the embodiments described below will not limit this disclosure.

[0011] (Configuration of radio wave control device) First, the configuration of the radio wave control device 100 according to this disclosure will be explained using Figure 1. Figure 1 is a diagram showing an example of the configuration of the radio wave control device according to this disclosure. As shown in Figure 1, the radio wave control device 100 according to this disclosure comprises a radio wave control board 1, a housing 10 (first housing 20, second housing 30), sheet metal 4, 5, 6, 7, 8, and a packing 9.

[0012] The radio wave control plate 1 is a plate that controls the direction of propagation of radio waves by reflection or refraction. The radio wave control plate 1 may be realized, for example, by a metasurface refraction plate that refractions radio waves at a refraction angle different from the incident angle. The radio wave control plate 1 includes a dielectric substrate and a plurality of phase modulation elements arranged on the dielectric substrate.

[0013] The enclosure 10 includes a first enclosure 20 and a second enclosure 30. In other words, the enclosure 10 has a structure in which the first enclosure 20 is housed inside the second enclosure 30.

[0014] The first housing 20 includes a first housing member 21 and a first housing member 22. The first housing 20 sandwiches the radio wave control board 1 between the first housing member 21 and the first housing member 22, and houses the radio wave control board 1 inside the first housing 20. Note that the first housing member 21 has holes for air pressure adjustment, which will be described later. Considering that the first housing 20 is to be installed outdoors, it is made of a weather-resistant material or a material with surface treatment.

[0015] The second housing 30 includes a second housing member 31 and a second housing member 32. Considering that the second housing 30 is to be installed outdoors, it is made of a weather-resistant material or a material with surface treatment. Note that the second housing member 31 is fixed by a sheet metal (second sheet metal) 6 and a sheet metal (third sheet metal) 7.

[0016] The sheet metals 4, 5, 6, 7, 8 are members that fix and support the housing 10 at the installation location. The combination of the sheet metal 4 and the sheet metal 5 is also called the first sheet metal, the sheet metal 6 is called the second sheet metal 6, and the sheet metal 7 is called the third sheet metal 7. The sheet metals 4, 5, 6, 7, 8 are made of a weather-resistant material or a material with surface treatment. The housing 10 is fixed to the structure by sandwiching the structure (such as a balcony railing or a pole of an apartment) to be installed between the sheet metals 7 and 8 and fastening them. Note that the sheet metal 4 is provided from the perspective of design.

[0017] The packing 9 is provided between the first housing member 21 and the first housing member 22 to make the inside of the first housing 20 airtight. The packing 9 may be, for example, a rubber packing.

[0018] (Housing for Radio Wave Control Board) (Regarding the In-plane Direction) Next, the configuration of the housing 10 for the radio wave control board according to the present disclosure will be described with reference to FIG. 2. FIG. 2 is a diagram showing the configuration of the housing for the radio wave control board according to the present disclosure. As shown in FIG. 2, in the housing 10 for the radio wave control board, the first housing 20 is sandwiched between the second housing member 31 and the second housing member 32, and the first housing 20 is housed inside the second housing 30.

[0019] ) Next, the dimensions of the housing 10 for the radio wave control board according to this disclosure will be explained with reference to Figure 3. Figure 3 is a diagram showing the dimensions of the housing for the radio wave control board according to this disclosure. As shown in Figure 3, the diameter Φ1 of the first housing 20 is smaller than the diameter Φ2 of the second housing member 31 that constitutes the second housing 30.

[0020] Next, the specific dimensional relationship between the first housing 20 and the second housing member 31 constituting the second housing 30 will be explained using Figure 4. Figure 4 is a diagram showing the position and the AA cross-section of the housing for the radio wave control board according to this disclosure. The diagram on the left of Figure 4 shows the position of the AA cross-section of the housing 10. The diagram on the right of Figure 4 is an AA cross-sectional view of the housing 10 for the radio wave control board according to this disclosure. As shown in the diagram on the left of Figure 4, the first housing 20 is housed inside the second housing 30, which includes the second housing member 31 and the second housing member 32. Also, as shown in the diagram on the right of Figure 4, the diameter Φ1 of the first housing 20 is formed to be smaller than the diameter Φ2 of the second housing member 31. Therefore, the second housing 30 is rotatable inside the first housing 20 in the in-plane direction (X direction) shown in Figure 4, in other words, in the direction along the plane horizontal to the radio wave control board 1. This makes it possible to adjust the refraction angle in the direction horizontal to the surface of the radio wave control board 1.

[0021] Next, the position of the markings that serve as scales for adjusting the angle in the plane of the housing 10 for the radio wave control panel according to this disclosure, as well as the position of the markings and projections that serve as markers, and the details of the markings and projections will be explained with reference to Figure 5. Figure 5 is a diagram showing the position of the markings that serve as scales for adjusting the angle in the plane of the housing for the radio wave control panel according to this disclosure, as well as the details of the markings and projections. The diagram on the left of Figure 5 shows the position of the markings that serve as scales for adjusting the angle in the plane of the housing 10 for the radio wave control panel, as well as the position of the markings and projections that serve as markers. As shown in the diagram on the left of Figure 5, the markings and projections are provided in the circled area near the base of the fixing part 33.

[0022] The diagram on the right side of Figure 5 is a detailed view a of the area circled in the left side of Figure 5. As shown in the diagram on the right side of Figure 5, a projection 31P is provided on the inner circumference of the second housing member 31. Also, as shown in the diagram on the right side of Figure 5, markings 20E are provided on the outer circumference of the first housing 20 to serve as indicators for angle adjustment in the in-plane direction. Note that the markings 20E may be arranged such that smaller markings 20Es are provided at predetermined angular intervals (e.g., 1 degree) and larger markings 20Eb are provided at angular intervals larger than that interval (e.g., 10 degrees). Therefore, by using the markings 20E as scales and the projection 31P as indicators, it becomes possible to accurately adjust the angle of the first housing 20, which houses the radio wave control board 1, in the in-plane direction (X direction).

[0023] Next, the fastening locations of the screws in the housing 10 for the radio wave control board according to this disclosure will be explained with reference to Figure 6. Figure 6 is a diagram showing the fastening locations of the screws in the housing for the radio wave control board according to this disclosure. By inserting screws into the screw holes circled in Figure 6 and turning the screws, the first housing 20 and the second housing 30 are fastened together with screws. This restricts the in-plane rotation of the first housing 20 inside the second housing 30. Therefore, the in-plane angle of the radio wave control board 1 housed inside the first housing 20 can be fixed.

[0024] (Regarding the horizontal direction) Next, the horizontal rotation of the housing 10 for the radio wave control panel will be explained using Figure 7. Figure 7 is a diagram showing the structure for fastening the housing and sheet metal for the radio wave control panel according to this disclosure. As shown in Figure 7, the housing 10 for the radio wave control panel according to this disclosure is fixed by being sandwiched between a first sheet metal (a combination of sheet metals 4 and 5) and a sheet metal (second sheet metal) 6. Before being fixed by being sandwiched between the first sheet metal (a combination of sheet metals 4 and 5) and the sheet metal (second sheet metal) 6, the housing 10 for the radio wave control panel is rotatable in the horizontal direction (Y direction) as shown in Figure 7, in other words, in a direction perpendicular to the surface of the radio wave control panel 1 and horizontal to the fixed surface on which the housing 10 is installed. Therefore, after adjusting the horizontal (Y-direction) angle of the housing 10 for the radio wave control board according to this disclosure, the housing 10 is sandwiched and fixed by the first sheet metal (combination of sheet metals 4 and 5) and the sheet metal (second sheet metal) 6, thereby making it possible to adjust the horizontal (Y-direction) angle of the radio wave control board 1 and then fix the adjusted angle.

[0025] Next, the positions of the markings that serve as scales for horizontal angle adjustment and the markings that serve as indicators on the housing 10 for the radio wave control panel according to this disclosure, as well as the details of these markings, will be explained with reference to Figure 8. Figure 8 is a diagram showing the positions of the markings that serve as scales for horizontal angle adjustment and the markings that serve as indicators on the housing 10 for the radio wave control panel according to this disclosure, as well as the details of these markings. The diagram on the left of Figure 8 shows the positions of the markings that serve as scales for horizontal angle adjustment and the markings that serve as indicators on the housing 10 for the radio wave control panel. As shown in the diagram on the left of Figure 8, these markings are provided near the fastening portion between the housing 10 for the radio wave control panel and the sheet metal 5.

[0026] The diagram on the right side of Figure 8 is a detailed view b of the area near the fastening portion between the housing 10 for the radio wave control board and the sheet metal 5. As shown in the diagram on the right side of Figure 8, a marking 31E is provided near the fastening portion of the second housing member 31 to the sheet metal 5, which serves as a guide for the horizontal rotation of the housing 10 for the radio wave control board according to this disclosure. Also, as shown in the diagram on the right side of Figure 8, a marking 5E is provided on the upper surface of the sheet metal 5, which serves as a scale for adjusting the angle of horizontal rotation of the housing 10 for the radio wave control board according to this disclosure. The marking 5E may include, for example, smaller markings 5Es provided at predetermined angular intervals (e.g., 1 degree) and larger markings 5Eb provided at angular intervals larger than said angular intervals (e.g., 10 degrees). Therefore, by using the marking 5E as a scale and the marking 31E as a guide, it is possible to accurately adjust the horizontal angle (Y direction) of the housing 10 that houses the radio wave control board 1.

[0027] Next, the method of fixing the first sheet metal (combination of sheet metals 4 and 5) and the sheet metal (second sheet metal) 6 of the housing 10 for the radio wave control board will be explained using Figure 9. Figure 9 shows the locations where the housing and sheet metal for the radio wave control board according to this disclosure are fastened with screws. Screws are inserted into the screw holes at the circled locations at the four corners of the first sheet metal (combination of sheet metals 4 and 5) and the sheet metal (second sheet metal) 6 shown in Figure 9, and by turning the screws, the first sheet metal (combination of sheet metals 4 and 5) and the sheet metal (second sheet metal) 6 are fastened together, and the housing 10 sandwiched between the first sheet metal (combination of sheet metals 4 and 5) and the sheet metal (second sheet metal) 6 is fixed. This makes it possible to restrict the horizontal rotation (Y direction) of the housing 10 for the radio wave control board according to this disclosure. Therefore, the horizontal angle of the radio wave control board 1 housed inside the housing 10 can be fixed.

[0028] (Regarding the vertical direction) Next, the vertical rotation of the housing 10 for the radio wave control board according to this disclosure will be explained using Figure 10. Figure 10 is a side view of the housing for the radio wave control board according to this disclosure. As shown in Figure 10, the housing 10 for the radio wave control board according to this disclosure is fastened with the first sheet metal (a combination of sheet metals 4 and 5) and the sheet metal (second sheet metal) 6, and then the sheet metal (third sheet metal) 7 is connected to the sheet metal (second sheet metal) 6.

[0029] Next, the method of connecting the housing 10 for the radio wave control board and the sheet metal according to this disclosure will be explained using Figure 11. Figure 11 is a front view and a side view of the housing for the radio wave control board according to this disclosure. As shown in side views a and b at both ends of Figure 11, the sheet metal (second sheet metal) 6 fastened to the housing 10 for the radio wave control board according to this disclosure is fastened and fixed to the sheet metal (third sheet metal) 7 by inserting screws into the screw holes circled in the figure and turning the screws. When the screws are loosened, the sheet metal (second sheet metal) 6 can rotate relative to the sheet metal (third sheet metal) 7 in the vertical direction (Z direction) shown in Figure 11, in other words, in a direction perpendicular to the surface of the radio wave control board 1 and perpendicular to the fixed surface on which the housing 10 is installed. Therefore, the vertical angle of the housing 10 for the radio wave control board can be adjusted.

[0030] Next, the location of the markings that serve as scales for vertical angle adjustment of the housing 10 for the radio wave control board according to this disclosure, as well as the details of these markings, will be explained using Figure 12. Figure 12 is a diagram showing the location of the markings that serve as scales for vertical angle adjustment of the housing for the radio wave control board according to this disclosure, as well as the details of these markings. The diagram on the left side of Figure 12 shows the location of the markings that serve as scales for vertical angle adjustment of the housing 10 for the radio wave control board, as well as the details of these markings. As shown in the diagram on the left side of Figure 12, these markings are provided in the circled areas of the sheet metal (second sheet metal) 6 and sheet metal (third sheet metal) 7 that are fastened to the housing 10 for the radio wave control board.

[0031] The diagram on the right side of Figure 12 is a detailed view c of the circled areas of the sheet metal (second sheet metal) 6 and sheet metal (third sheet metal) 7 fastened to the housing 10 for the radio wave control board. As shown in the diagram on the right side of Figure 12, a marking 6E is provided on the side of the sheet metal (second sheet metal) 6, which serves as a mark for the vertical rotation of the housing 10 for the radio wave control board according to this disclosure. Also, as shown in the diagram on the right side of Figure 12, a marking 7E is provided on the side of the sheet metal (third sheet metal) 7, which serves as a scale for adjusting the angle of vertical rotation of the housing 10 for the radio wave control board according to this disclosure. Note that the marking 7E may include, for example, smaller markings 7Es provided at predetermined angular intervals (e.g., 1 degree) and larger markings 7Eb provided at angular intervals larger than said angular intervals (e.g., 10 degrees). Therefore, by using the marking 7E as a scale and the marking 6E as a guide, it becomes possible to accurately adjust the vertical (Z-direction) angle of the housing 10 that houses the radio wave control board 1.

[0032] (Regarding the pressure adjustment sheet) Next, the pressure adjustment sheet S of the housing 10 for the radio wave control panel according to this disclosure will be explained using Figure 13. Figure 13 is a diagram showing the location where the pressure adjustment sheet of the housing for the radio wave control panel according to this disclosure is provided, and details of the pressure adjustment sheet. The diagram on the left of Figure 13 shows the location where the pressure adjustment sheet S of the housing 10 for the radio wave control panel according to this disclosure is provided. As shown in the diagram on the left of Figure 13, the pressure adjustment sheet S of the housing 10 for the radio wave control panel according to this disclosure is provided in the circled area on the outer periphery of the first housing member 21. The pressure adjustment sheet S is a sheet that allows air to pass through but does not allow water to pass through.

[0033] The diagram on the right side of Figure 13 is a detailed view d of the circled area on the outer periphery of the first housing member 21, where the pressure adjustment sheet S of the housing 10 for the radio wave control panel according to this disclosure is provided. As shown in the diagram on the right side of Figure 13, the pressure adjustment sheet S of the housing 10 for the radio wave control panel according to this disclosure is inserted into a hole H for the pressure adjustment sheet provided on the outer periphery of the first housing member 21.

[0034] Next, the contact state between the pressure adjustment sheet S and the first housing member 21 according to this disclosure will be explained using Figure 14. Figure 14 is a diagram showing the position and the BB cross-section of the first housing member according to this disclosure. The diagram on the left of Figure 14 shows the position of the BB cross-section of the first housing member 21 according to this disclosure. As shown in the diagram on the left of Figure 14, the BB cross-section of the first housing member 21 according to this disclosure is a cross-section cut perpendicular to the outer circumference of the first housing member 21.

[0035] The diagram on the right side of Figure 14 is a cross-sectional view BB of the first housing member 21 according to this disclosure. As shown in the diagram on the right side of Figure 14, the pressure adjustment sheet S according to this disclosure is inserted into the hole H for the pressure adjustment sheet of the first housing member 21 and is in contact with the first housing member 21. As shown in Figure 14, when the first housing 20 is airtightly sealed by the packing 9 provided between the first housing member 21 and the first housing member 22, a change in temperature will cause a change in the pressure inside the first housing 20. Therefore, by providing the pressure adjustment sheet S, when the pressure inside the first housing 20 becomes high, high-pressure air is released from inside the first housing 20 through the pressure adjustment sheet S to adjust the pressure inside the first housing 20. This makes it possible to reduce deformation of the housing 10 due to changes in the pressure inside the first housing 20, even when a temperature change occurs. When the pressure inside the first housing 20 becomes low, air flows in through the pressure adjustment sheet S to adjust the pressure inside the first housing 20.
