A technique for a dielectric lens and an antenna assembly. The dielectric lens that includes a for a reference surface and a pattern of varying thicknesses made from a first dielectric. The pattern of varying thicknesses is situated on the reference surface. The thickness differences between adjacent formations of the pattern of varying thicknesses is less than an incident wavelength of electromagnetic energy. The antenna includes mounting fixture, the dielectric lens connected to the mounting fixture, and a transceiver operatively coupled to the mounting fixture. The transceiver is configured to transmit an electromagnetic signal directed to the dielectric lens.
