Optimized etched hole size for suppressing the periodicity in the frequency response in photonic bandgap microstrip structures

摘要

Using ideal transmission line model, we find the optimized length for suppressing the periodicity in the frequency response in periodic structure. Optimized length is applied to photonic bandgap (PBG) microstrip structures and we show the existence of optimized etched hole size in ground plane for suppressing the periodicity in the frequency response in PBG microstrip structures and find them.
