摘要
本文提出一种具有宽带低雷达散射截面特征的缝隙耦合微带天线。通过将两种具有极化选择特性的频率选择表面单元交错布阵取代传统金属接地板,利用相位相消及透波特性实现带内、带外RCS同时减缩。仿真结果表明,本文设计的天线可以在很好保持原始天线辐射性能的前提下,实现1GHz~18GHz宽带RCS减缩,证明了设计的有效性。
A novel design of aperture-coupled microstrip antenna with broadband low radar cross section(RCS) is proposed. Hybrid frequency selective surface(FSS) structures consisting of two kinds of polarization-dependent folded split ring resonators(PDFSRRs) and square patches are utilized to replace the conventional metallic ground. By orthogonally arranging the PDFSRRs in a chessboard-like configuration, the band-stop characteristic contributes to the gain enhancement, while the zero degree points of reflection phase are utilized to achieve RCS reduction both in-band and out-of-band. Furthermore, with square patches periodically etched on the bottom of FSS structure, a new zero degree reflection phase is introduced to enhance the effect of RCS reduction. Full wave simulations and measurements demonstrate that the proposed antenna achieves RCS reduction from 1GHz to 18 GHz and gain enhancement compared with traditional microstrip antenna.
