Description

  The present invention relates to a radio wave lens antenna apparatus using a Luneberg lens that is used to receive broadcast / communication radio waves from geostationary satellites or ground fixed antennas or to transmit radio waves toward those satellites or antennas.

  Parabolic antennas are generally used for communication with geostationary satellites, but parabolic antennas can basically only deal with radio waves from one direction. In addition, it is necessary to match the three axes of the vertical direction (elevation angle), the horizontal direction (azimuth angle), and the in-plane direction of the antenna for installation, and the setting is very difficult, and the wind pressure load on the dish surface is supported by the mast. Therefore, the wind resistance is also inferior, and reception failure may occur due to mast bending during strong winds. In addition, if a strong mast is installed, problems in terms of cost and landscape arise, and it becomes easy to be subject to installation regulations not only in Japan but also in Europe and America.

  In order to solve these problems, a reflecting plate having a diameter larger than the lens diameter is provided on a bisected section of a hemispherical Luneberg lens formed of a dielectric, and the reflecting plate is attached to a wall or the like so that the reflecting plate is substantially vertical. A wall-mounted radio wave lens antenna device is disclosed in Patent Document 1 and Patent Document 2 below.

  The radio wave lens antenna devices of Patent Document 1 and Patent Document 2 have been devised to simplify the position adjustment of the primary radiator at the time of installation. However, when used for communication with geostationary satellites, particularly a plurality of geostationary satellites. Regarding installation adjustment, there were still some points to be devised.

In other words, a radio wave lens antenna device that is used in a vertical installation by combining a hemispherical Luneberg lens and a reflector requires information on the direction of the wall, veranda, fence, etc. to be installed. It is not easy to determine which direction is right for you. It is convenient if the wall or the like to be installed faces the communication partner, but if not, it is necessary to adjust the position of the primary radiator according to the deviation of the direction from the communication partner. Since the antenna devices of Patent Documents 1 and 2 are adjusted at the focal point of the lens by separately adjusting the longitude, latitude, and orientation of the primary radiator, it takes time to adjust the antenna device. In particular, when dealing with a plurality of geostationary satellites, the orientation of the wall is unknown, so it is necessary to find the focal position of each satellite locally, making installation adjustment difficult.

  Hereinafter, the configuration of 1) is referred to as the first invention, the configuration of 2) is the second invention, the configuration of 3) is the third invention, the configuration of 4) is the fourth invention, and the configuration of 5) is the fifth invention. 1-1), 1-2) is a modification of the first invention, 4-1) is a modification of the fourth invention, 5-1), 5-2) is a modification of the fifth invention. it can. All antenna devices have the same pattern as the installation surface on the surface of the lens and the reflector, or use a reflector made of transparent plastic with a reinforcing material such as a metal mesh inside. A method of assimilating the whole with a wall surface or the like can be adopted.

  The antenna devices 4) and 4-1) can be changed to those in which the reflector is inclined by θ degrees from the vertical state with respect to the ground. In this case, a line inclined by 2θ degrees passing through the center of the lens is used as the axis. And make it rotate.

  In the radio wave lens antenna device according to the first aspect of the invention, the arm is rotatable about a perpendicular passing through the center of the lens, and the primary radiator held by the arm maintains the posture pointing to the center of the lens by rotating the arm. It moves on a plane perpendicular to the axis and on a semicircle centered on the axis. Therefore, movement adjustment can be done only in one axis direction. Parabolic antennas that need to be aligned in three axes, or because the orientation of the installation wall is unknown, measure the direction each time, and select the data that matches the direction. As compared with the conventional lens antenna that performs the position adjustment, the adjustment at the time of installation becomes much easier. In particular, in the embodiment of the present invention, it is only necessary to adjust a small primary radiator without moving a large reflector like a parabolic antenna, so that the position can be easily and accurately adjusted.

  In the radio wave lens antenna device according to the second aspect of the invention, the reflector is rotated with the mast as a fulcrum, and the rotation is stopped at a position where the reception level of the receiver is maximized, and the reflector is fixed with an appropriate detent. Therefore, this antenna apparatus can also position the primary radiator at the optimum point only by adjustment in one axial direction.

  The radio wave lens antenna device according to the third aspect of the invention displaces the primary radiator by sliding it on the arm in the longitudinal direction of the arm, and moves the both ends of the arm in the same direction along the circular orbit. In combination, the primary radiator is positioned at the optimum point. Adjustment is easy by displaying a latitude line in advance on a cover or the like that covers the lens, and moving the primary radiator on the arm toward the target position while rotating the arm along the latitude line.

  The radio wave lens antenna device of the fourth invention is a combination of the arms used in the antenna devices of the first invention and the third invention, and the functions and effects of the antenna devices of the first invention and the third invention are combined. Demonstrated. The radio wave lens antenna device according to the fourth aspect of the invention is particularly effective when aligning the primary radiators to the focal positions of a plurality of satellites, and the position adjustment of the plurality of primary radiators can be easily performed collectively. it can.

  In the radio wave lens antenna device according to the fifth aspect of the invention, when the satellite is one or a plurality of satellites in the vicinity, the position of the reflecting surface is adjusted by moving the reflecting plate instead of adjusting the position of the primary radiator. If a large reflector that can absorb the deviation in the direction of the communication partner is used, troublesome adjustment is not necessary, but if this is done, the apparatus becomes large. In the antenna device according to the fifth aspect of the present invention, the reflecting plate can be moved to the optimum reflection region of the radio wave, so that the reflecting plate can be made as small as necessary. Further, in the first, third, and fourth inventions, the reflection plate can be reduced to the minimum necessary by combining with the fifth invention.

  In addition, any radio wave lens antenna device can be installed in close contact with the wall, and the reflector becomes assimilated with the wall and only the hemispherical lens bulges, so there is little discomfort in the landscape. When the lens and the reflection plate have the same pattern as the installation surface or the reflection plate is made transparent, the degree of assimilation of the antenna with respect to the wall surface or the like is increased, and the discomfort in the landscape can be further reduced.

  In addition to the fact that the antenna is directly supported by the wall surface or the like, the hemispherical lens is less susceptible to wind pressure, so that reception disturbance due to wind or the like is less likely to occur. Further, it is not necessary to install a robust mast, which is advantageous in terms of cost.

  FIG. 1 shows an embodiment of the antenna device of the first invention. This radio wave lens antenna device 1A includes a hemispherical Luneberg lens 2 formed of a dielectric, a hemispherical cover 3 that covers and protects the surface of the lens, and a reflection provided on a bisected section of the lens sphere. The plate 4, the arm 6 supported by the fixed shaft 5 combined with the reflecting plate 4, and the primary radiator 7 held by the arm 6 are integrally combined.

  The reflector 4 is larger than the diameter of the lens 2 in order to reliably capture radio waves from the communication partner (in the figure, the geostationary satellite S). The fixed shaft 5 is an axis that becomes the rotation center of the arm 6, and is positioned on a perpendicular line L that passes through the center of the lens 2 when the reflector 4 is attached to the installation portion so as to be substantially perpendicular to the ground. The posture becomes perpendicular to.

  The arm 6 is bent along the surface of the lens 2. The holding portion of the arm 6 is configured to rotate on the outer periphery of the fixed shaft 5 and is not movable in the axial direction to form a rotating portion 8. The arm 6 having the rotating portion 8 is attached to the arm 6. A primary radiator 7 arranged at the focal point is attached.

  Since the primary radiator 7 knows the position of the stationary satellite S of the communication partner, the latitude and elevation angle can be adjusted in advance, and the adjustment at the installation site is only the longitude adjustment according to the direction of the wall surface B. It's okay.

  When the arm 6 is slowly rotated in one direction with the fixed shaft 5 as a fulcrum, the primary radiator 7 is displaced along the spherical surface of the lens 2 while maintaining the posture pointing to the center of the lens, and accordingly, by the receiver. The reception level of radio waves changes gradually. Therefore, the rotation of the arm 6 is stopped at a position where the radio wave reception level is maximized, and the rotating portion 8 is fixed to the fixed shaft 5 with a set screw (not shown).

  Note that the antenna device 1A shown in the drawing is provided with a pattern for assimilating with the wall surface B as necessary on the surfaces of the cover 3 and the reflection plate 4 or by changing the reflection plate to a transparent reflection plate. A sense of incongruity can be eased.

  FIG. 2 shows another embodiment of the antenna device of the first invention. Depending on the direction of the wall surface B where the antenna device is installed, the installation location, etc., the reflector 4 is installed with a tilt of θ degrees forward or backward from the vertical state with respect to the ground as shown in FIGS. It may be effective from the viewpoint of blocking radio waves, reducing the size of the reflector, and preventing snow accumulation. The inclination of θ degrees of the reflecting plate 4 can be easily given by interposing the attachment 9 between the reflecting plate 4 and the wall surface B. When such attachment is performed, the influence of the inclination of the reflecting plate 4 is eliminated. Therefore, the holding portion of the arm 6 can be rotated about a line inclined by 2θ degrees in the inclination direction of the reflection plate 4.

  Here, the angle θ is ± 45 degrees or less when a line perpendicular to the ground is 0 degrees, and preferably within a range of ± 15 degrees. If the angle is forward, the snowfall resistance is excellent, and if the angle is on the back, the reflector can be miniaturized when receiving from a satellite with a high inclination.

FIG. 3 is a modification of the antenna device of FIG. This radio wave lens antenna device 1B is provided with a plurality of arms 6 in which the holding parts constituting the rotating parts 8 of the respective arms are arranged on the same axis while changing the height position. A circular reflector having a wide corresponding area is employed. The radio wave lens antenna device 1B of FIG. 3 calculates the installation position of the primary radiator in the arm longitudinal direction with respect to each arm 6 from the installation position and the position information of the communication partner, and fixes the primary radiator 7 to the position. The arm 6 is rotated, and the primary radiator 7 on the arm 6 is moved to the target point along the surface of the lens by the rotation.

  FIG. 4 shows an embodiment of the antenna device of the second invention. The radio wave lens antenna device 1C includes a mast 10 that is fixed to a wall surface B or the like, and a sleeve 12 at the tip of a connector 11 provided on the back surface of the reflector 4 is rotatably fitted to a vertical shaft portion of the mast 10. I am letting. In addition, the arm 6 that holds the primary radiator 7 has a base fixed on the reflector 4. Other configurations are the same as those of the antenna device of FIG. In the radio wave lens antenna apparatus 1C of FIG. 4 as well, the position of the primary radiator 7 is adjusted in advance so as to match the geostationary satellite of the communication partner. It is only necessary to perform the adjustment to rotate the position to the maximum. After the adjustment, the sleeve 12 is fixed to the mast 10 with a set screw or the like to prevent the antenna from rotating.

  FIG. 5 is an embodiment of the antenna device of the third invention. This radio wave lens antenna device 1D uses a circular reflecting plate 4 and a circular orbit 13 concentric with the lens 2 is provided on the reflecting plate 4. Further, the arm 6 holding the primary radiator 7 is formed in an arch shape so as to straddle the lens 2, and both ends of the arm 6 are movably attached to the circular orbit 13. In the radio wave lens antenna apparatus 1D of FIG. 5, both ends of the arm 6 are moved in the same direction along the circular orbit 13, and further, the primary radiator 7 is displaced on the arm 6 by sliding in the arm longitudinal direction. The primary radiator 7 is positioned at the optimum point by combining these two operations. A line on the lens surface parallel to a surface perpendicular to the lens axis is displayed in advance on the cover 3 or the like that covers the lens 2, and the arm 6 is rotated on the arm 6 along the line. When the primary radiator 7 is moved toward the target point (focal point), adjustment is easy.

  FIG. 6 is an embodiment of the antenna device of the fourth invention. This radio wave lens antenna device 1E has a structure in which an arm 6 of the antenna device of FIG. 1 is further added to the antenna device of FIG. Here, in order to distinguish between the two arms and the primary radiators attached to the respective arms, reference numerals 6 indicating the arms and reference numerals 7 indicating the primary radiators are given additional symbols a and b. The primary radiator 7a attached to the arm 6a is provided with a holder portion (not shown) that allows the arm 6b to rotate relative to each other in two axial directions. In the radio wave lens antenna apparatus 1E shown in FIG. 6, first, the arm 6a is rotated as shown in FIG. 8A, and the position where the reception sensitivity of the primary radiator 7a positioned and attached to the arm 6a is maximized. I will find it. Next, the arm 6a is fixed, and the elevation angle is changed so that the position of the arm 6b coincides with the holder portion of the holder portion of the primary radiator 7a attached to the arm 6a (FIG. 8B). . Then, the arm 6b is rotated along the circular orbit 13 while changing the elevation angle again, and the position where the reception sensitivity of the primary radiator 7b preliminarily positioned and attached to the arm 6b is maximized (for example, FIG. 8 ( c)).

  The radio wave lens antenna apparatus 1E of FIG. 6 can be adjusted and set by rotating the arms 6a and 6b, and does not require the most difficult measurement of the wall orientation. Therefore, it is suitable for use as a multi-beam antenna in which a plurality of primary radiators are attached to the arm 6b. The arm 6a can be removed after the adjustment is completed.

FIG. 7 shows a derivative type of the antenna apparatus of FIG. In the radio wave lens antenna apparatus 1E- ₁ of 7, when the arm 6a is rotated, the primary radiator 7a held by the arm 6a moves on a line on the lens surface parallel to a plane perpendicular to the lens axis. The arc-shaped arm 6b along the spherical surface of the lens 2 can rotate around the primary radiator 7a, and the primary radiator 7b held by the arm 6b moves in the direction of the dotted arrow by the rotation. The primary radiator 7b may be movable in the longitudinal direction of the arm 6b (the direction of the solid line arrow) or may be fixed.

The radio wave lens antenna device 1E- ₁ of FIG. 7 thus configured first rotates the arm 6a to first align the primary radiator 7a. Next, the arm 6b is rotated around the positioned primary radiator 7a to find a position where the reception sensitivity of the primary radiator 7b is maximized, and the primary radiator 7b is positioned there. Since the distance between the primary radiators 7a and 7b is not related to the direction of the antenna installation surface (wall), it can be obtained in advance from the latitude and longitude of the antenna installation point and the satellite position. In order to correspond to another satellite, the primary radiator corresponding to the previously calculated distance from the primary radiator may be positioned on the arm 6b and additionally set.

  In any of the exemplary antenna apparatuses, the polarization angle of the primary radiator can be adjusted by rotating the primary radiator in a holder (not shown) that holds each primary radiator. In addition, the antenna device of FIGS. 1 to 7 may have a large reflector depending on the direction of the wall or the latitude of the installation location, or the radio wave may be blocked by the primary radiator. As stated, the reflector can be made smaller or the blocking effect of the primary radiator can be minimized by providing the reflector with a vertical or lateral angle.

  FIG. 9 shows an embodiment of the antenna device of the fifth invention. This radio wave lens antenna device 1F straddles the lens 2 with a hemispherical Luneberg lens 2 whose surface is covered and protected by a hemispherical cover 3, a reflector 4 provided on a bisected section of the sphere of the lens 2 and the lens 2. The arch-shaped arm 6 capable of adjusting the elevation angle and the primary radiator 7 held at the focal position by the arm 6 are integrally combined.

  As shown in FIGS. 9A and 9B, the reflecting plate 4 is elongated in one direction (illustration is elliptical), and the lens 2 is arranged on the reflecting plate 4, and this is shown in FIG. 9C. As shown in FIG. 3, the lens is held together with a turntable on a mounting plate 15 fixed to the wall surface B and rotated together with the lens 2.

The radio wave lens antenna device 1F- ₁ of FIG. 10 includes a second reflecting plate 4 that is added to the first reflecting plate 4a having a diameter slightly larger than the lens diameter and the outer periphery (upper edge) of the first reflecting plate 4a. The second reflecting plate 4b is coupled to the first reflecting plate 4a at the central portion of the lens 2 so as to be relatively rotatable by the pivot shaft 14, and the second reflecting plate is used with the pivot shaft 14 as a fulcrum. 4b can be rotated. Although the first reflecting plate 4a is circular in FIG. 10, only the portion that comes into contact with the second reflecting plate 4b by relative rotation may be circular.

  In the case of the structure of FIG. 9 or FIG. 10, the arm 6 may be fixed to the reflecting plate to be rotated and rotated together with the reflecting plate, or supported by a wall, a mounting jig, a mast, etc. You may enable it to adjust the position of the primary radiator 7 in the form separated from rotation of the reflecting plate.

As shown in FIG. 11, the second reflecting plate 4b is detachable from the first reflecting plate 4a, the second reflecting plate 4b is removed from the first reflecting plate 4a and rotated, and the two reflecting plates are combined after rotation. Thus, the relative position after rotation may be fixed. As described above, in order to rotate the reflector in the direction of the target geostationary satellite S, the radio wave lens antenna devices 1F, 1F- ₁ , and 1F- ₂ are made more compact by providing the necessary reflectors in the necessary direction. Can be

  In the radio wave lens antenna device of the present invention exemplified above, the alignment of the primary radiator with respect to the communication partner can be adjusted in one axial direction, that is, only by rotating the arm or the antenna with respect to the mast. Even if it is not known, adjustment at the time of installation can be performed easily and quickly. In particular, even when dealing with multiple satellites, each primary radiator can be positioned at the focal position of the lens by adjusting only one axis, such as arm rotation, greatly reducing the adjustment time and reducing the work load. The

  Moreover, what adjusts by rotation of an arm can make a reflecting plate closely_contact | adhere to a wall surface, can relieve a sense of incongruity in a landscape surface, and can fully improve wind resistance. Further, since a robust mast is not required, it is advantageous in terms of cost.

  An adjustment that rotates the entire antenna with respect to the mast only needs to be adjusted in one axial direction, and the adjustment at the time of installation becomes much easier than the conventional antenna.

  In addition, the reflector can be rotated in the same plane around the center of the lens, and the reflector can be composed of a plurality of reflectors so that the position of the outer reflector can be changed. The antenna device can be further miniaturized by reducing the size of the reflector to the minimum necessary.
