Wideband planar dipole based on dual-layer artificial magnetic conductor

Abstract

A wideband planar dipole based on dual-layer artificial magnetic conductor (AMC) is designed. First, the size of dual-layer AMC is reduced by more than half, and the in-phase band is wider than the single-layer AMC. Then, the improvement of large scan angle can be obtained by the offset between two layers of AMC in two directions. At last, a wideband planar dipole with 24.5% bandwidth is achieved.
