(2) The building-passing wireless transmission repeater as set forth in claim (1) of the utility model registration claim, wherein the shielding plate is partially or entirely composed of a layered metal plate. (3) The building-passing wireless transmission relay as set forth in claim (1) of the above utility model registration claim, wherein the shielding plate is made of a radio wave absorbing material board or a board whose surface is covered with a radio wave absorbing material. Machine. The brief description of the drawing has been amended as follows. In the first line of page 6 of the specification, the phrase ``plane antenna'' is corrected to ``plane antenna.''

Claims

[Claims for Utility Model Registration] (1) A planar antenna that receives radio waves from outdoors or indoors and a planar antenna that transmits radio waves indoors or outdoors are arranged with their rear surfaces facing each other, and an amplifier is installed at the center of these planar antennas, and A repeater for wireless transmission that passes through a building, characterized by having a shielding plate arranged around the periphery over a wider area than the outer periphery of the flat antenna. (2) The building-passing wireless transmission repeater as set forth in claim (1) of the utility model registration claim, wherein the shielding plate is partially or entirely composed of a layered metal plate. (3) The building-passing wireless transmission relay as set forth in claim (1) of the above utility model registration claim, wherein the shielding plate is made of a radio wave absorbing material board or a board whose surface is covered with a radio wave absorbing material. Machine.
