Abstract

With the advent of planar photonic bandgap (PBG) materials, different topologies of PBG structures have been proposed to improve the bandgap performances of microwave signals. Conventional circular-patterned PBGs have constraints in the broadband stopband performance due to the high ripple heights in S-parameters. In this paper, we suggest a novel annular-ring-patterned PBG to improve the stopband bandwidth and the ripples. The aspect ratio of the annular-ring-patterned PBG plays an important role in controlling the bandwidth of the rejection band, as well as the ripple heights in the S-parameters of the PBG-engineered transmission lines.
