| Abstract: |
| Metasurface is a plane structure composed of sub-wavelength size units densely arranged,which has strong electromagnetic wave regulation capability.The new satellite antenna based on metasurface has great potential in alleviating the diversification of businesses and the surge of users.The authors introduce the current development trend of satellite antenna,divide metasurfaces into two categories,namely traditional antennas loaded with metasurface and pure metasurfaces,summarize the advantages of the antenna loaded with metasurfaces such as low profile,multi-polarization,beam control,and describe the antenna design of the metasurface acting as the main radiation element.They analyze the working principle,efficiency,advantages and disadvantages of metasurfaces in different antenna design schemes,and finally discuss the development direction of metasurface satellite antennas and point out that metasurface has practical value in the design of satellite antennas. |
