Abstract

Properties of propagating wave in a composite right/left-handed (CRLH) leaky wave antenna rely heavily on the constituent stripe patches. In this paper, we conducted full-wave simulations of structural resonances in a CRLH leaky wave antenna by using finite difference time domain (FDTD) method. E_z field distributions for several lowest-order modes in individual stripe patch were examined, which are named as structural resonances. The Bloch modes in a transmission line were also calculated at high symmetric points in k-space. Study shows that Bloch mode properties are closely related to those in an isolated structure. The mode power densities are well confined below or around the metallic strip patches, which enables tight binding approximation to estimate band properties in the vicinity of Γ point. The calculated dispersion diagram by FDTD tells us many new features, such as accidental degeneracy, a third band arisen from slab mode and the many anti-crossing phenomena. These features are of great importance to analyze the performance of CRLH leaky wave antennae.
