UNWANTED RADIO WAVE SUPPRESSING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an unwanted radio wave suppressing structure which can alleviate a wind load on the foundation and can be easily installed within the limited space. SOLUTION: Since vacant holes 11 are bored to the 20 to 80 % in the entire part of front surface of a plane type radio wave absorbing material 1, the wind blows through such vacant holes 11 and the wind load of the plane type radio wave absorbing material 1. Accordingly, the load applied on the foundation can be alleviated and the foundation can also be reduced in size. Therefore, the structure for suppressing the unwanted radio wave can be provided easily within the limited space. COPYRIGHT: (C)2004,JPO&NCIPI
