【摘要】 本文提出了一种反射相位可重构的双极化超表面。在超表面中加载PIN二极管,利用PIN二极管的导通和断开实现超表面上的表面散射电流相位的控制。将超表面结构加载在所设计的传统双极化的天线单元中,以实现对天线单元反射特性的调控。最终所设计的双极化散射可重构Vivaldi天线阵列的单站RCS可以在9.8 GHz达到14 dB的减缩。更多还原

【Abstract】 In this paper,a dual polarized metasurface with reconfigurable reflection phase is proposed.The PIN diode lied in the metasurface,which loaded into the dual-polarized antenna unit,controlles the phase of the surface scattering current aimed to realize the regulation of the reflection characteristics of the antenna unit.Finally,the dual-polarized scattering reconfigurable Vivaldi antenna array has four scattering states arrayed by designed unit.The monostatic RCS at 9.8 GHz can be reduced by 14 dB compared to reference array.更多还原
