摘要

本研究將導電材料和環氧樹脂做混合，覆蓋在FR4基板上，並且藉由改變各種覆蓋的結構與面積來探討S參數與雜訊抑制的特性。本研究利用HFSS模擬軟體探討各種覆蓋結構與覆蓋方式下1~10GHz的抑制特性，再用實驗結果驗證模擬的正確性，研究結果發現可以藉由改變覆蓋的面積、結構與位置，來達到最理想的雜訊抑制效果。導電薄膜必須與微帶線接觸，抑制效果才會良好，真正影響抑制效果的是寬度W，也就是導電薄膜和微帶線接觸的部分越多，抑制的效果也就越佳。覆蓋雙邊的抑制效果會比覆蓋單邊的效果來的較佳。

Conductive materials mixing with epoxy resin are coated on the FR4 substrates. 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.
