Meta-surface reconfigurable antenna array

Abstract

There is disclosed a reconfigurable antenna array comprising an RF feed, configured to receive RF signals from an RF source; a plurality of waveguide feed structures, each waveguide feed structure comprising a plurality of unit cells arranged end-to-end, each unit cell configured to transmit RF signals out of the unit cell; and an RF power distributor, operatively connected to said RF feed, configured to split the received RF signals into multiple channels and to allocate different channels to different respective waveguide feed structures, wherein each waveguide feed structure is configured to guide the RF signals of the channel allocated to the waveguide structure to the unit cells of the waveguide feed structure. Each unit cell comprises reconfigurable components configured to manipulate electromagnetic properties of the RF signals received by the RF feed and guided along the respective waveguide structure so as to control a radiation pattern of the antenna array.
