Dynamic metasurface antenna
WebWe present an approach for SAR imaging using an X-band ( 10 – 13.7 GHz) dynamic metasurface antenna (MSA). This newly developed antenna has over 6000 liquid-crystal-switched radiating elements that cover a circular area with an approximate diameter of 0.45 m. The MSA’s main beam can be steered electronically to spherical angles of up to ± ...
