该文采用分形互补型FSS(Frequency Selective Surfaces)结构作为微带天线的贴片与接地板,设计并制作了一种超宽带低RCS(Radar Cross Section)印刷天线。仿真结果表明,比之初始天线,天线相对带宽从2.9%扩展到140%,在整个天线频带内(3.9~22.1 GHz)RCS都得到了有效的减缩,减缩最大达到25.15 dB,同时保持较高的增益。测试结果与仿真具有较好的一致性,证实了该方法的有效性。

An ultra-wideband and low RCS (Radar Cross Section) printed antenna is designed and fabricated using the periodically loaded fractal complementary Frequency Selective Surfaces (FSS) on the upper patch and bottom ground plane, respectively. Simulated results show that the relative bandwidth of this novel antenna is significantly broadened from about 2.9%to about 140%, the RCS is reduced effectively to 25.15 dB, and the gain is maitained a high value within the entire band (3.9~22.1 GHz) compared to the original antenna. Experimental data show a reasonably good agreement between the simulation and measured results, and illustrate the validity of the method.
