In city area, electromagnetic interference caused by buildings is a very important problem. For example, a well known ghost phenomenon is caused by interaction between incident and reflected waves caused due to the presence of large and tall buildings. In this study, absorption characteristics in VHF band of ferrite mortar, mixed with four different size of ferrite grain respectively, are measured by using parallel wire line method. Furthermore, absorption characteristics in VHF band of radio wave absorber, combined ferrite mortar with carbon fiber sheet, are measured, and it is considered whether thin radio wave absorber can be realized. As a result, as the size of ferrite grain is small, absorption characteristics in VHF band improve. And the improvement of absorption characteristics in VHF band is possible by combining fertile mortar with carbon fiber sheet.
