摘要

提出了一种基于双五边形单元的宽带圆极化超表面天线。该天线主要由微带耦合馈电i型槽、超表面和空气层组成。i型槽产生线极化波，超表面完成线极化波到正弦波的转换。仿真结果表明，该天线的阻抗带宽为6.9 ~ 8.9 ghz, 3dB轴比带宽为7.21 ~ 8.50 ghz。它结构简单，具有3dB宽的轴比带宽，可广泛应用于无线通信系统中。

Design of Broadband Circularly Polarized Metasurface Antenna Based on Dual-pentagonal Units

A broadband circularly polarized (CP) metasurface antenna based on double pentagonal elements is proposed. The antenna is mainly composed of a microstrip coupling feeding I-shaped slot, a metasurface and an air layer. The I-shaped slot generates linearly polarized (LP) waves, and the metasurface completes the conversion from LP waves to CP waves. The simulated results show that the impedance bandwidth of the antenna is 6.9-8.9GHz, and the 3dB axial ratio bandwidth is 7.21–8.50GHz. It can be widely used in wireless communication systems for simple structure and wide 3dB axial ratio bandwidth.
