Abstract

Asymmetric two-dimensional (2D) electromagnetic band gap (EBG) waveguide with hexagonal lattice is theoretical investigated. The EBG cavity is made of metal rods with hexagonal lattice, which has an air hole in the center formed by remove a metal rod and two rods with different diameter. Changing the defect rod diameter, the eigenfrequency and S parameter can be simulated. The EBG cavity with large ratio of diameter and period is simulated and high transmisstivity between rectangle waveguide and EBG waveguide can be attained by the asymmetric coupling cavity.
