Ultra-Wideband RCS Reduction of Metasurface Antenna Based on Spoof Surface Plasmon Polariton and Transmission
MetadataShow full item record
In this paper, a metasurface antenna with ultra-broadband radar cross section (RCS) reduction was systematically presented and evaluated based on the spoof surface plasmon polariton (SSPP) and transmission. A circular metasurface consisted of twelve gradually increasing two-sided metallic grooves and an ultra-thin dielectric film. The evolutions of dispersion characteristic and near electric-field distributions were adequately demonstrated based on SSPP in simulation. Furthermore, the SSPP metasurface had been loaded on a common waveguide slot antenna. The simulation and laboratory measurements were performed to characterize RCS reduction, radiation patterns and scattering performance. A prototype of metasurface antenna had been fabrication and measurement to demonstrate the characteristics. Experiment data were carried out to verify the simulation results and measured results showed that the metasurface antenna exhibited ultra-wideband RCS reduction from 1 GHz to 10 GHz.
