A new stripline measuring setup for the characterisation of conductive gaskets up to 18 GHz

摘要

Due to the impact of higher and higher frequencies, the Shielding Effectiveness (SE) characterisation of shielding gaskets at frequencies above 1 GHz is needed for on board shielding applications. Although the standard IEEE Std 1302™ - 2008 is covering the characterisation of shielding gaskets up to 18 GHz, the methods proposed in this standard are not applicable for these thin and small ‘on board’ gaskets. A method overcoming this problem is proposed in this paper.
