Abstract (en)
There is disclosed A directional multi-band antenna, the antenna comprising: -an optical unit comprising an optical sensor; -an RF unit comprising an RF sensor; -a substantially planar optical lens, the optical lens comprising surface relief elements for beam forming, the lens being arranged to focus optical signal beams, incident along a first optical axis, onto the optical sensor, the optical lens being substantially transparent to RF signals, -an RF beam forming device arranged to receive RF signals incident along the first optical axis and focus such RF signals onto the RF sensor.
