摘　　要：提出了一种适用于星载SAR的新型双极化微带贴片天线。在孔径耦合馈电基础上,采用同轴线到微带线垂直过渡的方式,设计了一种新型双极化天线单元,在保持孔径耦合贴片天线固有优点的同时,使得交叉极化、隔离度得到很好改善,同时节约了阵中空间。该天线适合作为星载SAR阵列天线单元。In this paper, a new method of dual-polarization microstrip antenna for space-borne SAR application is presented. On the basis of aperture-coupling, adoping the vertical transition from coaxial line to microstrip line, this new type of dual-polarization antenna, retaining the inherent merit of the slot-coupled patch antenna is designed, which not only improve the cross-polarization and isolation, but also save great space in the array, it is very suitable to be the antenna cell.
