| Summary: | 碩士 === 國立臺灣大學 === 電信工程學研究所 === 95 === For the first time to characterize the physical mechanism of Coplanar Electromagnetic Band-Gap (Coplanar-EBG) structures, the viewpoint of the parallel-plate resonance cavity is proposed in this thesis. Besides, the overall arrangement of effective stackup layout and mechanism decision of the upper-side and lower-side of stop-band are also presented.
In the realistic high-speed digital circuit, the complicate trace layout and multilayer connection by via transitions are inevitable. Thus the position effect of arbitrary noise excitation to Coplanar-EBG becomes very important and will be taken into account in this thesis. In addition, to consider the efficiency, cost, and feasibility, the effective area of Coplanar-EBG layout is analyzed to meet the economic benefits.
Finally, based on the low coupling effect between two patches at the separate resonant frequencies, a novel Coplanar-EBG structure inducing a wideband band-stop filter is proposed, designed, examined, and validated.
