WALL STRUCTURE CAPABLE OF REDUCING RADIO WAVE INTERFERENCE

摘要

PROBLEM TO BE SOLVED: To enable the main beam of reflected radio waves of broadcast radio waves arriving from a transmission antenna provided higher than a building to be directed downwards so as to reach easily to the surface of an area in the vicinity of the building by a method wherein a radio wave reflector buried in the outer wall of the building is mounted in a vertical position. SOLUTION: A radio wave interfere reduction wall 10 has such a structure that a sheathing material 14 through which radio waves penetrate easily is arranged outside a concrete wall 18, and a radio wave reflector 16 is disposed between the sheathing material 14 and the concrete wall 18. The reflecting surface of the radio wave reflector 16 is composed of a large number of unit, bodies 16a which are possessed of sloping surfaces that are orientated so as to face obliquely upwards (angle of inclinationα=10 deg. to 12 deg.) and combined like saw-teeth. Radio waves reflected from the unit bodies 16a are made to travel obliquely upwards.
