No.10（2015）14.Proposal of GHz band EMI measurement without electromagnetic wave absorber

Hidekatsu Sasaki, Fumio Takahashi

  First, a validation was conducted on the use of a narrow beam antenna and the elevation control method for EMI measurement. And an elevation control program based on beam width and measuring distance was developed. Applying all of these, a proposal was made on the measuring method for GHz band. The evaluation was made on the applied SVSWR method in our procedure, and a comparison was made with current methods. The results of proposed method were not location dependent. As a result, the correlation of the measurements between the measured sites was obtained.
