Lens Antennas – Analysis and Synthesis at mm-waves

In this paper short introduction in dielectric lens antennas at mm-waves will be given. Dielectric lens antennas become more popular as applications start to migrate to higher frequencies where lens dimensions and weight become small enough and allow easy integration. Typically used feeds and lens shapes will be discussed together with global optimization techniques and analyzing kernels employed for lens antenna optimizations and synthesis with special emphasis to methods used by the author. Finally some remarks regarding lens production
