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.
