| 摘 要： | 本文提出一种新型C/L双波段、双极化共口径天线子阵设计,其中C波段双极化、L波段单极化工作,子阵应用于一维较大角度扫描、另一维有限扫描的二维有源相控阵天线中。C波段选择了高效率的缝隙波导天线,L波段则选择了尺寸较小的腔体缝隙天线。该天线适合于双波段多极化星载合成孔径雷达系统中。

| Abstract: | A new subarray antenna consists of a C band dual polarized waveguide slot antenna and an L band cavity backed slot antenna with shared apertures is presented. A big 2-D scanning active phased antenna array should be expanded with the subarray, which scans a moderate angle in one dimension and a limited angle in another dimension. The antenna array meets the requirement of a dual band multipolarization SAR application specially. |
