Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a reflector used for, for example, an antenna device or a radar device, and a method of manufacturing the same.
[0002]
[Prior art]
Generally, as a method of installing a reflector having a large diameter of several meters, a supporting structure is installed at a desired location, and a desired mirror surface is formed on the supporting structure. A reflector is assembled and arranged with a mirror adjusting mechanism interposed. Then, the reflection plate assembled to the support structure is finely adjusted to a desired mirror surface accuracy by using the mirror surface adjustment mechanism and is used for operations such as communication (for example, see Patent Document 1).
[0003]
By the way, such a reflecting mirror first produces a mirror-surface forming die according to a forming method such as metal forming or resin forming by press working, drawing, etc., and obtains a desired surface accuracy using the mirror-surface forming die. The reflecting plate is molded. Next, the reflection plate thus formed is mounted on a support structure installed at a desired place so as to be capable of adjusting the mirror surface via the mirror adjustment mechanism.
[0004]
However, in the case of the above-mentioned reflecting mirror, since the manufacturing process includes the manufacturing of a molding die for forming the reflecting plate, if the assembling operation is included, there is an inconvenience that much time is required for manufacturing.
[0005]
Further, in the above-described method for manufacturing a reflecting mirror, since a mold needs to be manufactured, there is also a problem that the unit price per unit becomes extremely expensive depending on the number of manufactured molds.
[0006]
On the other hand, in the field of recent communications, there is a strong demand for larger reflectors as communication capacity increases, and as a variety of reflectors as communication services diversify.
[0007]
If these requirements are satisfied, each time a different reflecting mirror is manufactured, it is necessary to manufacture a large mold that spends a lot of time in manufacturing. There is a problem that the unit price per unit becomes very expensive.
[0008]
Note that such a situation is not limited to the field of communication, and is the same in the field of radar.
