Abstract :
This paper presents a novel compact dual-band electromagnetic bandgap (EBG) structure utilizing cascaded mushroom-like structures with and without chip capacitors loading. Direct transmission method is used to determine the band-gap of the EBG structure. The effects of loading capacitors between the neighboring metal patches on the EBG properties are investigated. The units loaded with and without capacitors are cascaded to form a dual-band EBG structure, with the fractional band widths of 25.5% and 38.7% respectively. The simulation and experimental results show that the overall bandgap covers the stopbands produced by the two original uniform structures.
