Novel 1-D Photonic Bandgap Structure and Resonator for Microstrip Circuits

摘要

This paper presents new kind of microstrip transmission line incorporating 1-D helix photonic bandgap (HPBG) unit cell. Finite difference time domain (FDTD) simulation shows that the structure exhibits remarkable bandstop effects. Several cells connected in series form an excellent band-stop filter. Using 1-D HPBG unit cells, we also demonstrate a novel high-Q defect resonator.
