It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements well known to those skilled in the art have not been described in detail so as not to obscure the present application.
In the present application, the "longitudinal direction" refers to the longitudinal direction of the radome (cover body), unless otherwise specified.
First, the overall technical concept of the radome according to the present application is explained. According to the radome of this application through the cross-sectional shape that changes the cover main part to further the transition of the air current that obtains according to the experiment is twisted and is set up the line of tripping with the isolated position at the specific position of cover main part, thereby realizes that the radome of this application compares with current radome and has obtained the optimization of qxcomm technology wind-load.
The structure of a radome according to an embodiment of the present application is described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, an antenna cover according to an embodiment of the present application has a long rod structure extending linearly as a whole. The radome includes a radome body 1 and a trip wire 2 fixed to an outer surface of the radome body 1.
As shown in fig. 1 and 3, a space for housing components that realize the antenna function is formed inside the cover main body 1. In the present embodiment, the cover body 1 has a cross section perpendicular to the longitudinal direction L of the radome, and the cross-sectional shape of any portion of the cover body 1 is the same. The cross-sectional shape of the cover main body 1 of the radome is optimized to achieve omnidirectional wind load optimization.
Specifically, as shown in fig. 3, the cross-sectional shape of the cover main body 1 is formed into a closed shape. The cross-sectional shape comprises one straight line segment LS and a plurality of circular ARC segments ARC1 to ARC6. The sectional shape is symmetrical with respect to a reference line passing through a midpoint of the straight line segment LS and perpendicular to the straight line segment LS. On one side of the reference line (the right side in fig. 3), the cross-sectional shape includes a first ARC segment ARC1, a second ARC segment ARC2, and a third ARC segment ARC3 connected to one side end of the straight line segment LS. One end of the first ARC line segment ARC1 is connected with one side end of the straight line segment LS, the other end of the first ARC line segment ARC1 is connected with one end of the second ARC line segment ARC2, and the other end of the second ARC line segment ARC2 is connected with one end of the third ARC line segment ARC3. As described above, the cross-sectional shape of the cross-section of the mask body 1 is symmetrical about the reference line, and on the other side (left side in fig. 3) of the reference line, the cross-sectional shape includes the fourth ARC segment ARC4, the fifth ARC segment ARC5, and the sixth ARC segment ARC6 connected to the other side end of the straight line segment LS. The fourth ARC line segment ARC4 and the first ARC line segment ARC1 are symmetrical about the reference line, the fifth ARC line segment ARC5 and the second ARC line segment ARC2 are symmetrical about the reference line, and the sixth ARC line segment ARC6 and the third ARC line segment ARC3 are symmetrical about the reference line. One end of the fourth ARC line segment ARC4 is connected with the other side end of the straight line segment LS, the other end of the fourth ARC line segment ARC4 is connected with one end of the fifth ARC line segment ARC5, the other end of the fifth ARC line segment ARC5 is connected with one end of the sixth ARC line segment ARC6, and the other end of the sixth ARC line segment ARC6 is connected with the other end of the third ARC line segment ARC3. In fact, the other ends of the sixth ARC segment ARC6 and the third ARC segment ARC3 are coincident and both located on the reference line, and the sixth ARC segment ARC6 and the third ARC segment ARC3 can be regarded as the same ARC segment.
The centers of circles corresponding to all the ARC line segments (the first ARC line segment ARC1 to the sixth ARC line segment ARC 6) are located inside the closed shape. On one side of the datum line, the curvature radiuses of the ARC line segments ARC1 to ARC3 from one side end of the straight line segment LS become larger in sequence, that is, the curvature radius of the first ARC line segment ARC1 is smaller than that of the second ARC line segment ARC2, and the curvature radius of the second ARC line segment ARC2 is smaller than that of the third ARC coil. Further, the length of the third ARC segment ARC3 is greater than the length of the first ARC segment ARC1, and the length of the first ARC segment ARC1 is greater than the length of the second ARC segment ARC 2. On the other side of the reference line, the curvature radii of the ARC segments ARC4 to ARC6 from the other side end of the straight line segment LS become larger in sequence, that is, the curvature radius of the fourth ARC segment ARC4 is smaller than that of the fifth ARC segment ARC5, and the curvature radius of the fifth ARC segment ARC5 is smaller than that of the sixth ARC coil. Further, the length of the sixth ARC segment ARC6 is greater than the length of the fourth ARC segment ARC4, and the length of the fourth ARC segment ARC4 is greater than the length of the fifth ARC segment ARC 5.
Further, except for the connecting position between the third ARC line segment ARC3 and the sixth ARC line segment ARC6, the outer surfaces of the connecting positions of the two adjacent ARC line segments form chamfers, especially fillets, so that a smooth connection mode is adopted between the two adjacent ARC line segments.
In this way, the cover body 1 having the above-described sectional shape is advantageous in optimizing the wind load applied to the radome by the radome against wind from various directions, thereby reducing wind resistance.
In the present embodiment, through experiments, the purpose of optimizing the omnidirectional wind load of the present application can be better achieved when the following relational expression is satisfied for the arc line segment in the cross section of the shroud body 1 of the present application.
When the middle point of the straight line segment LS is the origin of coordinates, the x-axis is along the straight line where the straight line segment LS is located, and the forward direction of the x-axis faces one side of the reference line, the y-axis is along the reference line, and the forward direction of the y-axis faces the third ARC line segment ARC3 and the sixth ARC line segment ARC6,
the three arc segments on one side of the reference line satisfy the following relational expression.
The first ARC segment ARC1 satisfies the following relation: (x-a) 2 +(y-0.6a) 2 ＝0.36a 2 And x belongs to (a, 1.6 a), and the coordinate of the circle center O1 corresponding to the first ARC line segment ARC1 is (a, 0.6 a).
The second ARC segment ARC2 satisfies the following relation: (x-0.6 a) 2 +(y-0.7a) 2 ＝a 2 And x belongs to (1.5a, 1.6a), and the coordinate of the circle center O2 corresponding to the second ARC line section ARC2 is (0.6a, 0.7a).
The third ARC segment ARC3 satisfies the following relation: x is the number of 2 +(y-0.4a) 2 ＝2.78a 2 And x belongs to (0, 1.5a), and the coordinate of the center O3 corresponding to the second ARC line segment ARC2 is (0, 0.4a).
As described above, since the cross-sectional shape of the cover main body 1 in the cross section is symmetrical with respect to the reference line, the three arc segments on the other side of the reference line satisfy the following relational expression.
The fourth ARC segment ARC4 satisfies the following relation: (x + a) 2 +(y-0.6a) 2 ＝0.36a 2 And x belongs to (-1.6 a, -a), and the coordinate of the center of the circle corresponding to the fourth ARC segment ARC4 is (-a, 0.6 a).
The fifth ARC line segment ARC5 satisfies the following relation: (x +0.6 a) 2 +(y-0.7a) 2 ＝a 2 And x belongs to (-1.6 a, -1.5 a), and the coordinate of the center of the circle corresponding to the fifth circular ARC segment ARC5 is (-0.6a, 0.7a).
The sixth ARC line segment ARC6 satisfies the following relation: x is the number of 2 +(y-0.4a) 2 ＝2.78a 2 And x belongs to (-1.5a, 0), the coordinate of the center of the circle corresponding to the sixth ARC line segment ARC6 is (0, 0.4a), and the center of the circle corresponding to the sixth ARC line segment ARC6 and the center of the circle corresponding to the third ARC line segment ARC3 are located at the same coordinate point.
Further, the length of the straight line segment LS is 2a.
In the above relational expression, a is a dimensionless constant and may be an arbitrary real number. By setting the dimensionless functional relationship, the application of the cross-sectional shape of the present application to antennas of different sizes is facilitated.
Further, as shown in fig. 1 and 2, the catch wire 2 extends along the longitudinal direction L of the cover main body 1, and the length of the catch wire 2 is equal to the length of the cover main body 1. The catch wire 2 is formed in a configuration protruding from the outer surface of the cover main body 1. In this embodiment, the trip line 2 is disposed at a midpoint of the third ARC segment ARC3, a midpoint of the sixth ARC segment, a connection between the first ARC segment ARC1 and the second ARC segment ARC2, and a connection between the fourth ARC segment and the fifth ARC segment. The arrangement of the trip wire 2 can separate the airflow formed by wind at a desired position on the antenna housing, so that the wind load applied to the antenna housing by the antenna housing to the wind from all directions is further optimized.
As shown in fig. 4A to 4C, the shape of the trip wire 2 in cross section may be rectangular, trapezoidal (e.g., isosceles trapezoid), or triangular (equilateral triangle). The maximum height of the trip wire 2 protruding from the outer surface of the cover main body 1 may be about 1 mm. That is, when the cross section of the trip wire 2 is rectangular and the long side of the rectangle is connected to the outer surface of the cover main body 1, the length of the short side of the rectangle is about 1 mm. When the cross section of the trip wire 2 is an isosceles trapezoid and the long bottom side of the isosceles trapezoid is connected with the outer surface of the cover main body 1, the height of the isosceles trapezoid is about 1 mm. When the cross section of the trip wire 2 is an equilateral triangle and one side of the equilateral triangle is connected with the outer surface of the cover main body 1, the height of the equilateral triangle is about 1 mm. In addition, other sizes of the cross section of the trip wire 2 may be set as required, for example, when the cross section of the trip wire 2 is an isosceles trapezoid, the size of the long base of the isosceles trapezoid may be 5mm and the size of the short base may be 4mm.
Experiments show that by using a radome with the above cross-sectional dimensions, the wind resistance can be optimized in most directions compared to existing radomes. The data in table 1 below are parameters measured by a wind tunnel test for an existing radome (the sectional shape having a flat configuration) and a radome according to the present application (the sectional shape having a shape as described above, i.e., a mushroom-like shape).
TABLE 1
In table 1 above, when the windward angle is 0 °, the radome is in the first state in the wind tunnel as follows: the wind direction in the wind tunnel is over against the convex vertex part of the radome according to the present application (that is, the wind direction is towards the part formed by the other end points of the third ARC segment ARC3 and the sixth ARC segment ARC6 of each section of the radome, and the wind direction extends along the reference line); when the windward angle is 180 degrees, the antenna housing is in the following second state in the wind tunnel: the wind direction in the wind tunnel is opposite to the flat plate part of the radome according to the application (namely, the wind direction faces to the part formed by straight line sections LS of all the sections of the radome, and the wind direction extends along a datum line); other angles of attack are angles through which the radome turns from the first state around its central axis towards the second state.
Further, the present application also provides an antenna device, which may be a wireless base station antenna device for a communication network. The antenna device may include one antenna cover or a plurality of antenna covers as described above, depending on the case of the component that performs the antenna function.
