【摘要】 本文研究了Jerusalem十字架型有源频率选择表面(Active FSS)反射系数的频率响应特性,重点考察了其双频谐振特性以及其中一个谐振频率的可调谐特性。通过在有源FSS结构中加载可调电抗,模拟不同偏压或不同电流下的有源器件(如PIN管)。利用等效模拟电路对有源FSS结构谐振特性的电调原理进行解释。应用CST软件分析了Jerusalem型有源FSS在不同感抗加载时的频响特性。本文最后针对电控可调FSS中有源器件的馈电问题,提出了一种直流偏置线的排布方法。更多还原

【Abstract】 In this paper,a novel Jerusalem Cross Active Frequency-Selective Surface(JC-AFSS) with dual band and tunable characteristics has been studied.The active element,such as PIN,under different feedings,is simulated by tunable reactance loading on active FSS.The tunable dual band characteristics of the structure have been demonstrated by means of equivalent-circuit models, and the frequency response has been analyzed by CST.In the end,a useful method for the anangement of bias feeding line for active elements has been proposed.更多还原
