Abstract :
The radiation performance of a planar meta-surface based on dipoles and wires are experimentally investigated. A dipole antenna closely placed to the meta-surface is used as a feeding source of the meta-surface obtaining a gain value of 6.8 dBi; the thickness of the whole system is 0.135 lambda0 and the aperture efficiency 82 %. A study of the mutual coupling between dipole antenna array elements is also presented. On average, between 3 and 14 dB reduction of the mutual coupling is achieved when the meta-surface is used.
