摘要

提出一种新型共用口径L/C双波段双极化单层开孔式结构的合成孔径雷达(synthetic aperture radar,SAR)天线，这种新型结构旨在提高L/C双波段双极化共口径SAR天线中L波段的天线带宽.对天线进行仿真、加工和测试.测试结果表明，L波段的反射系数不大于-10 dB的相对带宽达到13.7%，C波段相对带宽达到17.0%.实验结果验证了新型结构的有效性.

Abstract

A novel L/C dual-band dual-polarized shared-aperture antenna with a single-layer perforated structure is proposed for synthetic aperture radar (SAR) applications. The aim is to broaden the impedance bandwidth in the lower L-band of the L/C shared-aperture SAR antenna. The antenna element has been simulated, fabricated and measured. The measurements show that the bandwidths, defined as reflection coefficient being less than or equal to -10 dB, is increased to 13.7% in the lower L-band, while that of the higher C-band reaches 17.0%. Experimental results have verified this design.
