摘要

本文研究了将半圆形阵列天线集成到人工磁导体(AMC)中，使其在9.41 GHz的期望工作频率下谐振。所提出的AMC在9.41 GHz具有高磁导率(约7.08)的高阻抗表面，具有完美的磁导体特性。因此，AMC能够堆叠在半圆形附近。仿真结果表明，与无AMC的8.44 dB和96%相比，AMC成功地将天线的增益和效率分别提高到9.55 dB和97%。此外，使用AMC可以观察到从395 MHz到398 MHz的带宽略有改善。模拟结果和实测结果在反射系数和辐射方向图上一致。

Performance Enhancement of Semicircular Shaped Array Antenna using Metasurface

This work studies the integration of a semicircular shaped array antenna into an Artificial Magnetic Conductor (AMC) which resonate at the desired operating frequency of 9.41 GHz. The proposed AMC performs as a high impedance surface with a high permeability (approximately 7.08) at 9.41 GHz, with a perfect magnetic conductor characteristic. As result, the AMC is able to be stacked adjacent to the semicircular shaped. The simulation results show that the AMC has successfully enhanced the gain and efficiency of the antenna to 9.55 dB and 97% respectively compared to 8.44 dB and 96% without AMC. Besides that, a slight bandwidth improvement, from 395 MHz to 398 MHz can be observed with the AMC. Both simulated and measured results show a good agreement in term of reflection coefficients and radiation patterns.
