Abstract
A holographic antenna comprises an optically transparent substrate; a hologram arranged on a first surface of the substrate, the hologram comprising two or more hologram stripes, each having a plurality of linearly arranged hologram pixels, each comprising a switching component; a ground plane arranged on a second surface, opposite the first surface, of the substrate; one or more surface wave launchers arranged on or in a surface of the substrate, the one or more surface wave launchers being configured to feed a feeding signal in a frequency range above 50 GHz into the hologram; and control lines connected to the switching components of the hologram pixels for controlling the hologram pixels individually or in groups.
