【摘要】 本文通过加贴片的方式,扰乱了缺陷地结构接地板上的返回电流分布,进而改变了缺陷地结构的等效电感,同时贴片的存在使得电场增加,从而增加了结构的等效电容,提出了三种新型缺陷地结构,分析了新型结构的电流分布对电感的影响,并计算了等效电感和等效电容,验证了理论的正确性,最后用所提出的三种结构中的一种设计和测试了一种带阻滤波器。更多还原

【Abstract】 The return current flows on the metallic gruound plane of the Defected Ground Structurd is perturbed by embedding conductor patch,and The effetctive inductance changed,the effective capacitance increased,Then the influence of return current on inductance is analyzed, The effective inductace and effective capacitance is computed,Finally a bandstop filter is designed by using a novel defected ground structure.更多还原
