Dynamic metasurface antenna
Webtigate how metasurface antennas in general can expand SAR capabilities and open new research avenues. This paper begins with a review of the dynamic metasurface described in [31] and a discussion of how it can generate various radiation patterns. Conventional stripmap and spotlight SAR modalities are then demonstrated with the device. Sub- WebJul 1, 2024 · Such a dynamic metasurface-based antenna platform is an interesting alternative to transmit highly directive but also continuously steerable beams at large angles, thus showing great potential in wireless communications and smart antennas where real-time control is desired. 2.
