Abstract
An antenna system comprises an antenna array having a plurality of antenna elements each having a resonator configured for emitting non-optical radiation, and a resonance tuning device for tuning a resonance frequency of the resonator. The antenna system also comprises an optical array having a plurality of light activated devices respectively aligned with the plurality of antenna elements, and a network of waveguides arranged to guide light to each light activated device. Each activated device provides electrical energy to a respective resonance tuning device upon activation by light via a respective waveguide.
