【摘要】 本文设计了一种X波段集成太阳电池的波导裂缝天线阵列,它由8根波导裂缝太阳电池天线单元组成。每根脊波导上部宽边包含8个位于中心线的纵向辐射缝,位于辐射缝下方的8个不同高度的调谐钉实现了天线低旁瓣设计。太阳电池位于天线的顶部和底部,可实现100%的阳光照射。该天线工作频率为9.6-9.8 GHz,H面副瓣电平小于-22.74 dB。含与不含太阳电池的天线辐射效率分别为69.5%-74%和83.4%-97.3%。太阳电池在天线上下表面的覆盖率分别为82.2%和91.4%。这种金属太阳电池天线可用于卫星合成孔径雷达应用。更多还原

【Abstract】 This paper presents a X-band waveguide slot solar cell antenna array,which consists of 8 waveguide slot antenna units.Each ridge waveguide on the upper wide side contains 8 longitudinal radiation slots located on the centerline.Eight tuning pins at different heights below the radiation slots are used for low sidelobe antenna design.The solar cells are located at the top and bottom of the antenna array,enabling 100% sunlight exposure.The operating frequency of the antenna is 9.6-9.8 GHz,with a sidelobe level below-22.74 dB in the H-plane.The radiation efficiency of the antenna with and without solar cells is 69.5%-74% and83.4%-97.3%,respectively.The coverage ratio of the solar cells on the upper and lower surfaces of the antenna is 82.2% and 91.4%,respectively.This metal solar cell antenna can be used for Synthetic Aperture Radar applications.更多还原
