題である。SUMMARY OF THE INVENTION Normal BS antenna 1
Since is a parabolic antenna having a parabolic surface, a normal flat solar cell 6 cannot be accurately attached. It is convenient to have a solar cell having a paraboloid, but such a solar cell is difficult to manufacture. Further, if the solar cell 6 is simply attached to the surface of the antenna 1, radio waves enter the solar cell 6 and are reflected, causing a loss in the solar cell 6. These are the problems to be solved by the present invention.
