A Novel EBG Power Plane with Stopband Enhancement using Artificial Substrate
暂无分享,去创建一个
Based on the conventional low-period coplanar EBG (LPC-EBG) structure, a novel power plane is proposed to extend the bandwidth of the stopband for ground bounce elimination using artificial substrate EBG (AS-EBG) structure. With properly embedded high-K rods and air rods in the substrate of the LPC-EBG power plane, the resonance frequencies can be shifted and thus result in the enhancement of the first stopband. Over 60% improvement of the stopband bandwidth can be achieved in this work. This improvement is also verified by the dispersion diagram calculated using the 2-D transmission-line model.
