Abstract

To increase efficiency of optical control of phase shifting elements, arrangements comprising optical lenses are presented. The optical lenses may be arranged in reflective arrays so as to focus light from a light source on a phase shifting element, which may be placed in a feed point of an antenna, such as for example a lithographic antenna. In some embodiments, thus both optical controlling radiation and radio frequency, RF, power are concentrated in substantially the same place.
