Abstract

Abstract

A broadband planar printed Magneto-Electric (ME) dipole antenna and a Wide-Band Metamaterial Absorber (WBMA) with polarization-insensitive and wide-angle absorption are designed for X band application. The absorber exhibits absorptivity above 90% from 7.2 GHz to 12.6 GHz under normal incidence. When the incident angle increases to 45, the absorptivity is still above 90% at X band. By applying the absorber around the antenna, the RCS of antenna is reduced significantly. Simulated and experimental results show a monostatic RCS reduction above 3 dB from 7.2 GHz to 12.6 GHz, and the peak reduction is up to 23.8 dB under different polarized waves. At the center working frequency of 10 GHz, the bistatic RCS decreases significantly from-90 to +90 under TE polarized wave and from-35 to+35 under TM polarized wave while the radiation performance remains unchanged basically, which proves that the absorber has great absorptivity.
