摘要

介绍了一种基于新型极化转换超表面(PCM)的低轮廓宽带圆极化(CP)缝隙天线。该CP天线由馈电槽天线和具有两个轴对称贴片的新型PCM组成。PCM实现了5.8 GHz至7.2 GHz入射波的90度偏振转换反射。实测结果表明，CP天线在-10 dB带宽为2.5 GHz (4.5-7 GHz)、AR带宽为1 GHz (5.3-6.3 GHz)时具有良好的性能。此外，该天线具有良好的圆极化特性、简单的结构和低轮廓，使其成为c波段(4-8 GHz)应用的可行候选。

Novel Polarization Conversion Metasurface Based Circular Polarized Slot Antenna with Low Profile

A low-profile, wideband circular polarized (CP) slot antenna based on a novel polarization conversion metasurface (PCM) is illuminated in this paper. The CP antenna is composed of a feeding slot antenna and a novel PCM with two axisymmetric patches. PCM realizes the 90 degrees polarization conversion reflection for the incident wave from 5.8 GHz to 7.2 GHz. The measured results showed that the CP antenna achieves good performance with a -10 dB bandwidth of 2.5 GHz (4.5–7 GHz) and an AR bandwidth of 1 GHz (5.3–6.3 GHz). In addition, the proposed antenna has good circular polarization characteristics, simple structure and low profile, which make it a viable candidate for C-band (4–8 GHz) application.
