研究目的
Investigating the performance of double-walled carbon nanotube composite materials (DWCNTs-composite) and their bundles (CB-DWCNTs) for dipole antenna applications at terahertz frequency range.
研究成果
The study demonstrates that coating DWCNTs with graphite or copper materials enhances the performance of dipole antennas at terahertz frequencies. The B-DWCNTs-copper dipole antenna is suitable for high-frequency applications, while the B-DWCNTs-graphite dipole antenna is better for lower frequency applications. The efficiency of these antennas is improved compared to non-coated DWCNT antennas.
研究不足
The study focuses on the terahertz frequency range and specific composite materials (graphite and copper coated DWCNTs). The performance might vary with other materials or frequency ranges.
1：Experimental Design and Method Selection:
The study involves mathematical modeling and analysis of DWCNTs-composite material for modeling and simulation purposes. The bundle of DWCNTs-composite material is designed based on this modeling approach.
2：Sample Selection and Data Sources:
The study uses DWCNTs coated by a thin jacket of another material (graphite or copper) to construct composite materials.
3：List of Experimental Equipment and Materials:
CST (MWS) software is used for designing and implementing dipole antennas of the composite materials.
4：Experimental Procedures and Operational Workflow:
The dipole antennas are designed with circular cross-sections for B-DWCNTs-composite and CB-DWCNT materials. Comparative studies are performed to analyze the dependency of size and frequency on the DWCNT-composite material.
5：Data Analysis Methods:
The performance of the antennas is evaluated based on S11 parameters, resonant frequency, gain, bandwidth, and efficiency.
