In this letter, wideband radar cross-section (RCS) reduction on checkerboard metasurfaces with dual resonance and surface wave suppression is proposed. In addition to dual resonance, the surface wave suppression of the unit cells is applied to extend the-10 dB RCS reduction bandwidth limit of the upper frequency band that is generated by the surface wave. As a result, the proposed structure increases the high frequency of the-10 dB RCS reduction from 14.9 to 16.32 GHz. Fabricated checkerboard metasurfaces are shown, and simulation and measurement results are presented in this letter.
