摘　　要：提出了一种与太阳能电池板集成的反射阵天线。用太阳能片底部金属层作为反射阵单元的辐射贴片,使得照射在太阳能电池上的光照不受天线遮挡,实现了最大化的光电转化效率。反射阵单元尺寸为0.4λ_(0)×0.4λ_(0)。单元相移范围达到543°。用该单元组成了单元数为15×15的反射阵列天线,阵面口径大小为690 mm×690 mm(6λ_(0)×6λ_(0))。采用标准增益喇叭天线作为反射阵馈源。仿真结果表明,在2.6 GHz反射阵的增益达到22.5 dBi,口径效率为39.5%。A reflectarray antenna integrated with solar cells is proposed.Metallic layer on the bottom of the solar cell is used as the radiation patch of the reflectarray element,which allows 100%insolation of the solar cells when directly facing a light source without blocking by the antenna.The maximum photoelectric conversion efficiency is achieved.The dimension of the element of the reflectarray is 0.4λ_(0)×0.4λ_(0) and the range of a phase shift can achieve 543°.A 15×15 reflectarray antenna with an overall size of 690 mm×690 mm(6λ_(0)×6λ_(0))is designed with the element.The reflectarray antenna is fed by a standard gain horn.The simulation results show that the gain of the reflectarray antenna reaches 22.5 dBi at 2.6 GHz,and the aperture efficiency reaches 39.5%.
