We study a homogeneous dielectric lens typical for mm-wave and used to improve the radiation properties of printed antennas. The aim of the paper is to reveal characteristic features of numerical optimization and to demonstrate that profile shaping enables one to reduse the lens size while keeping the directivity of an antenna fed by a line sourse at the same level.

The optimization of the lens profile is carried out with a genetic algoriyhm. The lens profile is represented by cubic splines whose node coordinates are optimized to provide the best possible directivity of a line sourse located close to the lens flat bottom.
