AB In this communication, the reconfigurability mechanisms for beam steering at a fixed frequency in a leakywave antenna based on Huygens metasurfaces are reviewed. A preliminary design for a forward-to-backward scanning antenna at 24 GHz is proposed based on the use of a commercial liquid crystal (er ranging from 2.46 to 3.54). The simulation results show that the beam steers when the permittivity of the liquid crystal (partially filling the waveguide, with a 560 um high layer) is reconfigured. It is shown that the antenna can meet the challenges of this technology (a very thin layer of liquid crystal and a not very wide range of permittivity) while obtaining scanning from -15 to 15º maintaining the directivity around 17 dBi, including broadside.
