In high-speed mobile communication systems such as 5G, so-called coverage holes occur where high-quality communication cannot be provided due to shielding by buildings. As a countermeasure, the use of a metasurface reflector that reflects radio waves in directions other than regular reflection is being studied. In the metasurface reflector consisting of multiple unit cells, the wider the reflection angle, the stronger the coupling between the elements and the worse the reflection characteristics. In this report, we propose a method of designing multiple unit cells as a super-cell and improving the reflection characteristics using the steepest gradient method. Specifically, a method to improve the reflection intensity of the metasurface and a method to reduce the sidelobe level of the reflection pattern have been proposed. Numerical simulation results show that the proposed method is particularly effective in reducing side lobes. |
