摘要

本文提出了一种高效的高增益圆极化天线。设计了一种圆极化金属镀层天线，在FR4衬底上制作了非对称无功阻抗面(RIS)，并将其置于天线上方，以增加3db的轴比带宽。该天线提供S11小于- 20db的带宽和5.699 ~ 5.912 GHz以上的3db轴比带宽。该天线提供9.9 dBi增益，90%以上的天线效率和超过20 dB的F/B瓣比。旁瓣电平< - 20db，交叉极化<;-15分贝。制作并测试了天线。实测结果与仿真结果吻合较好。天线整体尺寸为60mm × 60mm × 4.6 mm。

Efficient high gain circularly polarized microstrip antenna using asymetrical RIS surface

In this paper an efficient high gain circularly polarized antenna is proposed. A circularly polarized metal plated antenna is designed and an asymmetrical reactive impedance surface (RIS) is fabricated on a FR4 superstrate and placed above the antenna to increase the 3 dB axial ratio bandwidth. The antenna provides S11 less than -20 dB and 3 dB axial ratio bandwidth over 5.699-5.912 GHz. The antenna offers 9.9 dBi gain, more than 90 % antenna efficiency and more than 20 dB F/B lobe ratio. Side lobe level is <;-20 dB and cross polarization is <; -15 dB. The antenna is fabricated and tested. The measured results agree with simulation results. The overall antenna dimensions are 60 mm × 60 mm × 4.6 mm.
