Abstract : This paper deals with the concept and the realization of inhomogeneous (index gradient) lens antennas in millimeter waves range. Firstly, the authors present a new technological process allowing to tune the dielectric constant of one unique base material. This technology gives the opportunity to change the dielectric constant from 1 to 3 (for this study) and to design Luneburg or Fresnel Zone Plate lenses up to 100GHz presented in the second part of this paper. Measurement of real prototypes demonstrate that this simple and low cost technology is available up to millimeter waves. © 2018 IEEE.
