Abstract

A metamaterial-based antenna is presented that consists of periodic electromagnetic bandgap (EBG) cells on the top plane and triangular slots on the bottom ground plane. This proposed microstrip patch antenna can yield left-handed, zeroth-order and right-handed metamaterial resonances owing to the asymmetrical periodic structure of honeycomb-like EBG. Experimentally, the efficiency of this antenna is improved by about 14.7 at the zeroth-order resonant mode as the triangular slot length on the ground plane is increased from 0 to 5.5mm.
