| 總結: | The Reconfigurable Reflectarray Antenna, widely known as the RRAs, has been a substantial topic pertaining to radar applications and communication applications. When compared with traditional phased arrays, the RRAs have been proven to have the edge due to high efficiency, cost-effectiveness, portability, and lower system complexity, which resolves the many concerns in advanced high-gain antennas. To do so, the implementation of metasurfaces to achieve reconfigurability in terms of transmission, reflection, and polarisation conversion. This metasurface will contain 2 metallic layers and a dielectric substrate at the center. The key will be the lumped element, a PIN diode of different transmission and reflection functions when switched on and off respectively. The middle layer comprises of Taconic TLT6 that shape optical wavefronts as a dielectric substrate (refractive index and Electric & Magnetic resonance). The top metallic layer is composed of a metallic strip, designed to convert the polarization. Both numerical simulations and experimental results expect to show reconfigurable performance of the proposed active metasurface. |
