摘　　要：Anovel compact E shape High Impedance Surface(HIS) Electromagnetic Band-Gap(EBG) comprising Amended Minkowski Fractal Boundary(AMFB),Added Metal Strips(AMS),and metal plated via printed on a Rogers TMM 10i substrate is presented.The first order AMFB and ABS are introduced for equivalent capacitance enhancement and miniaturization with effective space-filling characteristics.The dimension of lattice size is only The proposed structure exhibits a most compact characteristic about 35% size reduction as compared with conven-tional mushroom-like HIS-EBG,and better surface-wave decoupling of around 9 dB at the operating frequency band.Details of design parameters which affect the whole performance of certain band-gap are intensively investigated.A constructed prototype is potential candidate for antenna system per-formance enhancement.Anovel compact E shape High Impedance Surface （HIS） Electromagnetic Band-Gap （EBG） comprising Amended Minkowski Fractal Boundary （AMFB）, Added Metal Strips （AMS）, and metal plated via printed on a Rogers TMM 10i （εr=9.8, t=2.0 mm） substrate is presented. The first order AMFB and ABS are introduced for equivalent capacitance enhancement and miniaturization with effective space-filling characteristics. The dimension of lattice size is only 0.058λ0. The proposed structure exhibits a most compact characteristic about 35% size reduction as compared with conventional mushroom-like HIS-EBG, and better surface-wave decoupling of around 9 dB at the operating frequency band. Details of design parameters which affect the whole performance of certain band-gap are intensively investigated. A constructed prototype is potential candidate for antenna system performance enhancement.
