| contents | This work introduces a reconfigurable leaky-waveguide antenna with a simplified biasing scheme for dynamic beam steering at a fixed frequency. Unlike prior metasurface-aided leaky-waveguide antennas that employ tunable metasurfaces as radiative apertures, our approach utilizes them as a waveguide wall solely to control the guided mode. As a result, the proposed structure eliminates the need for local biasing schemes commonly required in earlier designs, significantly simplifying the biasing process. The radiation is achieved by employing passive, angle-independent metasurfaces that allow beam steering across broadside. The feasibility and effectiveness of the proposed design are validated through full-wave simulations. |
