中文摘要：
针对一般谐振型电磁带隙结构相对带宽比较窄的特点,依据电磁带隙结构带隙形成机理和等效电路分析模型,该文提出了一种基于低介电常数低成本基底的紧凑宽带平面电磁带隙结构。实验结果表明,新结构具有54.1%的相对带宽,相比文献结构有超过100%的相对带宽改善,并且中心频率降低了25.2%,达到了实现紧凑宽带UC-EBG结构的目的。
英文摘要：
Aiming at the characteristic of relative narrower bandwidth of present Electromagnetic Band-Gap （EBG） structure, according to the physical mechanism of EBG structures and equivalent circuit model, a novel compact wideband planar EBG structure is proposed constructed on low permittivity low-cost substrate in this paper. The measured results show that relative bandwidth of the novel structure reaches 54.1% and obtain more than 100% bandwidth improvement, and simultaneously the center frequency is reduced by 25.2%. The objective of realizing compact wideband UC-EBG structure is attained.
