A new inhomogeneous lens, made up of three hemispherical shells is proposed. By approximating the Maxwell fish-eye law, this gradient index lens exhibits interesting focusing properties. A prototype of this lens fed by a waveguide has been measured in the 76-81GHz band showing an average gain of 21.7dBi.
