研究目的
To design graphene based plasmonic printed dipole and patch antenna resonating at 1 THz and compare them with their metal versions to highlight the reduction in antenna length.
研究成果
Graphene-based antennas offer significant miniaturization potential compared to their metal counterparts, with comparable performance in terms of return loss and radiation pattern. This is attributed to the excitation of SPP waves at terahertz frequencies. The study demonstrates the feasibility of using graphene for compact antenna designs in terahertz applications.
研究不足
The study is limited to simulations and theoretical analysis without physical prototype testing. The practical implementation challenges, such as fabrication and integration with existing systems, are not addressed.
