摘要

碳纳米管(CNT)在许多应用中显示出巨大的意义。并将其应用于贴片天线中，以评估CNTs作为射频辐射体的性能。本文首先对相同尺寸的传统铜贴片天线与环氧树脂-碳纳米管复合天线进行了比较。然后提出了条纹环氧碳纳米管天线来研究其辐射方向图选择性能。结果表明，在贴片天线上添加环氧树脂-碳纳米管复合层，使谐振频率发生150 MHz的偏移。碳纳米管的取向对贴片天线的辐射方向有独特的极化敏感性。当条带与贴片天线的e面平行时，其无线电性能最佳。当碳纳米管与贴片天线的e面垂直放置时，观察到内视镜的总增益降低了8dB。这一发现将被进一步研究，它可能有潜在的应用于极化选择性射频系统，如GNSS-R系统。

A carbon nanotube patch antenna for polarization selective radiation performance

Carbon nanotube (CNT) has shown its huge significance in many applications. It was also applied to the patch antenna to evaluate the performance of the CNTs as a radio frequency radiator, This paper first presented a comparison between a conventional copper patch antenna and an epoxy-CNT composite antenna with the same dimension. Then the striped epoxy-CNT antenna was proposed to investigate the radiation pattern selective performance. The results showed that the epoxy-CNT composite layer added on the patch antenna shifted the resonant frequency with 150 MHz. The orientation of the CNT strip was found to have a unique polarization sensitivity behavior effects on the radiation pattern of the patch antenna. Optimal radio performance was observed when the strips were located in parallel with the E-plane of the patch antenna. When the CNT was located orthogonally to the E-plane of the patch antenna, a reduction of total gain of 8dB was observed in the boresight. This finding will be studied further, and it may have potential applications to the polarization-selective radio frequency system, such as the GNSS-R system.
