Wideband planar dipole based on dual-layer artificial magnetic conductor
The Journal of Engineering, 2019 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.
