The unwanted electromagnetic(EM) radiation wave generated from the wireless module in millimeter-wave band used for the car radar influences some error and performance degradation of electronic equipments. In this paper, to reduce this unwanted EM wave, a optimal design to add the function of EM wave absorption to the lid for the module is examined. Therefore the alumina containing carbon black is used as a wave absorption material of the lid. The absorption of 20dB or more is obtained as a measured result with the cover added the EM wave absorption function in 60GHz.<br>Furthermore, we analyzed the wireless module in millimeter-wave band by using the designed material for the lid. It is clarified that the radiation and the reflection electric power are greatly suppressed by loss electric power of the lid. Therefore, the effective data for suppressing the unwanted EM radiation noise from wireless module in millimeter-wave band can be provided.
