Abstract

With the rapid development of modern wireless communication technology, antennas, as a core component of the wireless communication system, have become a research focus. The axial ratio (AR) of an antenna is particularly critical to its overall performance. Increasing AR bandwidth can ensure circular polarization performance, enhance system compatibility, and improve anti-interference capabilities. This paper presents a design of a circularly polarized patch antenna based on metasurface technology. By incorporating a transmission-type polarization conversion metasurface, copper plates embedded vertically in the ground plane, and n-shaped parasitic patches, significant improvements in antenna performance are achieved. The tests show that the antenna achieves a 43.4% S₁₁ bandwidth within the frequency range of 4.94–7.68 GHz, and a 31.4% 3 dB AR bandwidth within the range of 4.83–6.43 GHz, demonstrating excellent performance. This study provides new technical support and design ideas for the field of wireless communication.

一种基于透射极化转换超表面的宽带圆极化天线

随着现代无线通信技术的飞速发展，天线作为无线通信系统的核心部件成为研究热点。天线的轴向比（AR）对其整体性能尤为重要。增加AR带宽可以保证圆极化性能，增强系统兼容性，提高抗干扰能力。本文提出了一种基于超表面技术的圆极化贴片天线的设计。通过结合透射型极化转换超表面、垂直嵌入地平面的铜板和n形寄生贴片，天线性能得到了显著改善。测试表明，该天线在4.94 ~ 7.68 GHz频率范围内实现了43.4%的S11带宽，在4.83 ~ 6.43 GHz频率范围内实现了31.4%的3 dB AR带宽，表现出优异的性能。本研究为无线通信领域提供了新的技术支持和设计思路。
