In this study, a metasurface-based antenna array that achieves wideband radiation and broadband radar cross section (RCS) reduction is constructed. The broadband radiation performance is achieved by utilizing the metasurface itself, without introducing additional radiators. The radiation mechanism of the radiator elements and the proposed antenna array is analyzed using characteristic mode theory. Both simulations and measurements are conducted to verify the performance of the antenna array. The results show a wide impedance bandwidth, gain bandwidth, and significant monostatic RCS reduction within a specific frequency range.
In this communication, a metasurface-based antenna array with wideband radiation and broadband radar cross section (RCS) reduction is constructed. Without introducing additional radiators, the broadband radiation performance of the antenna array is achieved by inspiring the metasurface itself. In addition, the characteristic mode theory is introduced to analyze the radiation mechanism of the radiator elements and the proposed antenna array. Both simulations and measurements are carried out to verify the performance of the proposed antenna array. The results show that the impedance bandwidth and 3 dB gain bandwidth of the proposed antenna array are 5.1-9.0 and 5.1-8.0 GHz, respectively, with a peak gain of 12.1 dBi. Monostatic RCS reduction more than 10 dB is achieved within the frequency band of 6.0-26.2 GHz.
