Polarization cancelation method to reduce the monostatic radar cross section (RCS) is investigated thoroughly. The inherent bandwidth of rotatable unit cells is determined. Also, 0-dB RCS reduction bandwidth of any arbitrary method including polarization cancelation method is investigated. A special unit cell is proposed to reduce RCS over 100% fractional bandwidth. Finally, a structure is fabricated and measured so that results in verifying the performance of the proposed unit cell.
