Web2 mei 2024 · Measured scattering patterns of the proposed spatiotemporal metasurface with different modulation mechanisms at 4–7 GHz. (a) Scattering-field distribution based on space-modulated signals. (b) Scattering-field distribution based on time-modulated signals. Unequal time steps are encoded into the metasurface with a modulation period of 0.1 ms. WebThe designed wideband antenna is realized by employing a low‐cost phase shifting mechanism that uses a Metasurface (MTS) superstrate which is placed above the radiating surface of the antenna. A design chart is developed for the determination of the required phase variation based on the distance between MTS and the antenna radiator. lauterbach spedition gmbh
