A wideband monostatic and bistatic radar cross-section (RCS) reduction of microstrip antenna array is proposed and investigated. By using coding metasurface on the proposed antenna, the reflected energy is diffused scattering to more directions. A remarkable monostatic RCS reduction is achieved from 6 to 7.6 GHz and 9.5 to 26 GHz covering the working frequency band, and the bistatic RCS of proposed antenna is also effectively suppressed. The proposed antenna still maintains in a compact structure, while the antenna radiation performance is preserved. Both the reference and proposed antennas are fabricated and measured in anechoic chamber, and the results show that there is a good agreement between simulations and measurements.
