Abstract
A novel shared aperture metasurface (SA-MS) for ultra-wideband radar cross section (RCS) reduction is designed and fabricated in this paper. The SA-MS is composed of a kind of perfect metamaterial absorber (PMA) and two kinds of artificial magnetic conductors (AMCs), where they share the same physical aperture in horizontal dimensionality with an aperiodic arrangement. Based on this design, the RCS reduction bandwidth of the SA -MS can be remarkably broadened due to the cascade connection of different working modes, which include absorption for the incident wave of PMA and phase cancellation between three kinds of MS lattices. Simulation and measurement results indicate that a 3-dB RCS reduction is achieved from 4.98 GHz to 14.14 GHz (95.8% relative bandwidth) for both x- and y- polarized incident waves and the 6-dB RCS reduction bands for the x- and y-polarizations are 5.04 GHz-13.02 GHz, 5.06 GHz-8.66 GHz and 9.22 GHz-12.12 GHz, respectively.
