Design of a Reconfigurable Metasurface Antenna for Dynamic Near-Field Focusing


Conference Paper

© 2018 IEEE. We show the design of a dynamically reconfigurable holographic metasurface antenna for near-field beam-focusing applications. A metasurface layer is used to modulate the guided-mode reference to an aperture field of interest producing the desired radiated wavefront. Exciting the dynamically reconfigurable metasurface layer with the guided-mode reference produces a reconfigurable focus in the near-field of the antenna aperture. The reconfigurable operation is achieved in an-all electronic manner, without the need for any mechanical moving apparatus or phase shifting circuits.
