论文摘要
我们对碳纳米管（CNT）膜微带天线进行系统的数值模拟，以各种设备设计参数来制造灵活和耐用的应用。选择适当的材料用于导电膜和一致性且稳健的微带天线的底物对于提高辐射效率和降低损失至关重要，同时保持机械性能。 CNT已被视为一种有前途的纳米材料，表现出出色的电气和机械性能，作为微波可穿戴设备的理想功能。考虑到导体和底物的材料特性，我们检查了CNT膜电导率的可能范围，导电膜的厚度以及底物的介电常数和厚度。此外，我们对CNT膜中电导率的不均匀空间分布进行建模，以评估其对天线性能的影响。我们对材料常数和电导率空间模式的广泛研究提出了设计指南，该指南针对以微波频率运行的CNT导电膜制成的最佳微带天线。
We perform systematic numerical simulations for carbon nanotube (CNT) film microstrip antennas to fabricate flexible and durable applications in terms of various device design parameters. The selection of appropriate materials for conductive films and a substrate of the conformable and robust microstrip antennas are crucial to increase the radiation efficiency and to reduce the losses while maintaining the mechanical properties. CNTs have been spotlighted as a promising nano-material, exhibiting excellent electrical and mechanical performances as desirable features for microwave wearable devices. Considering the material properties of the conductor and the substrate, we examine the possible ranges of the CNT film conductivities, conductive film thickness, and a dielectric constant and thickness of a substrate. Furthermore, we model non-uniform spatial distributions of conductivity in the CNT film to assess their impact on the antenna performance. Our extensive studies of material constants and conductivity spatial patterns propose design guidelines for optimal microstrip antennas made of CNT conductive films operating in microwave frequencies.
