Abstract: The focal properties and radiation characteristics of an epsilon-near-zero metamaterial lens are investigated numerically and experimentally in the D-band. The experimental focusing enhancement of the lens is ~16 dB. The directivity of the lens antenna configuration at 144 GHz is ~18 dBi and the corresponding gain scan loss below 3 dB is achieved for angles up to ±15 deg.
