This paper presents a novel approach to reducing radar cross section (RCS) using a 2D multi-layer Van Atta array based on the phase cancellation principle. By controlling the phase of transmission lines using wideband phase shifters, the proposed array can achieve significant RCS reduction at a wide frequency range of 8 GHz to 11 GHz. Both theoretical calculations and experimental measurements were conducted to evaluate the performance of the Van Atta array with phase shifters. Results showed significant RCS reduction from various incident angles, demonstrating the effectiveness of the proposed design in achieving wideband RCS reduction at the X-band.
