研究目的
Designing a transparent dual-band antenna resonating at both 750 GHz and 1.1 THz for satellite systems, evaluating material losses, and demonstrating its ability to work in THz bands through low-frequency scaling.
研究成果
The designed dual-band ITO optically transparent rectangular patch antenna shows better results than conventional antennas with copper and gold conductors at 0.75 and 1.1 THz. Low-frequency scaled versions demonstrate the antenna's ability to work in THz bands, with improved bandwidth and radiation characteristics when using ITO.
研究不足
The study focuses on specific frequencies and materials, and the performance may vary with different materials or frequencies. The fabrication process may introduce slight frequency shifts.
