摘　　要：将电磁带隙(EBG)结构加载在电源/地平面之间,依据理论分析对模型结构以及各项参数进行优化。设计出抑制深度为-80 dB、禁带宽度为10 GHz的超宽禁带电源/地平面,在拥有优良抑制电磁干扰能力的同时,也保证了信号的完整性。在禁带内,该平面可以有效地抑制电路之间特别是共用电源/地平面的数字电路与射频电路之间所引起的电磁干扰。仿真实验表明,该设计取得了理想的效果。In this paper,we have designed a new type of the power / ground pair planes with ultra-band gap,after the theoretical analysis,the model structure has been optimized the configuration and design parameters,guarantee signal integrity and also keep excellent depth of suppression,under-80 dB and with wide of band gap is 10 GHz.The plane can be effectively inhibit the noise,electromagnetic interference and other problems between the circuits,especially between the RF circuit and digital circuit sharing power / ground pair planes.The experimental results show that,we have achieved the desired test result.
