In reality, the optical-transformation media with complicated and continuous electromagnetic parameters are difficult to realize. In this work, we propose a discrete embedded optical transformation from which a layered high-gain lens antenna is designed. All layers of the lens antenna are composed of homogeneous and uniaxially anisotropic metamaterials, which are simple and realizable. When the layered lens is embedded in a horn antenna, the lens antenna provides a high-directivity radiation beam. We also use the discrete optical transformation to design a multibeam high-gain antenna.
