Dynamic RCS Reduction Performances of Antenna Array with Coding Metasurface

Table 1

Basic performance comparison of three different layout antennas and reference antenna.

	Reference antenna	Checkerboard layout	New chessboard layout	“0101” square ring nested layout
	6 dBsm RCS reduction bandwidth	—	8.7–10.5 GHz; 18.8%	9.2–10.5 GHz; 13.2%	9.0–10.2 GHz; 12.5%
Maximum reduction of RCS at the scattering resonance point	—	21.0 dBsm; 9.5 GHz	19.8 dBsm; 9.5 GHz	15.0 dBsm; 9.5 GHz
Strong scattering beam angle
