Metamaterial Lensing Surface for a Weight-Reduced Metal Waveguide Antenna on Satellites

In this paper, a new method is suggested to relieve satellite payloads of rapid growth in weight attributed to metal waveguide antennas. A metasurface lens does away with the waveguide array antenna as a heavy structure but employs a short waveguide which is combined with the metasurface. Antenna directivity and gain become high though the system gets lighter than the conventional development methods. A metasurface lens is designed to increase the antenna gain of an X-band metal waveguide antenna and is observed to jump by over 7 dB. The far-field patterns of the primary antenna and the final structure are given to show benefits of this method and the compact size will be mentioned
