Title:
COMPOSITE BEAM FORMING WITH MULTIPLE INSTANCES HOLOGRAPHIC METASURFACE ANTENNAS
Document Type and Number:
WIPO Patent Application WO/2019/139745
Kind Code:
A1
Abstract:
A method for beam forming includes providing multiple instances of holographic metasurface antennas (HMAs), a reference wave source coupled to the HMAs, and a hologram function for each of the HMAs; combining the object waves of the plurality of HMAs, generated in response to the reference wave, to produce a composite beam; and modifying a phase angle of the object wave from one or more of the HMAs by modifying the hologram function of the one or more HMAs in order to modify the composite beam.
