The effect of the area of the coated films on high frequency signal suppression is investigated in this work. The HFSS simulator is employed to study the frequency response of the signal suppression during the frequency range between 1 and 10 GHz. The simulated results are compared with the experimental ones. To have a better high frequency signal suppression, the coated films must be in contact with the signal lines. The width and length of the coated films play an important role in the high frequency signal suppression. Besides, the suppression effect for double side coated films is better than that of single side.
