This Project aims to create dielectric antennas for high-frequency terahertz sources, i.e., resonant tunnelling diodes. Motivated by their end-use, the Project expects to deliver high-efficiency, high-gain low-profile cavity antennas for free-space operation and Yagi-Uda couplers for guided-mode operation. Silicon will be a key material for both types of terahertz structures to achieve highest efficiency. Effective medium theory will enable performance, functionality, and integrability, while maintaining structural simplicity for cost benefits. The expected outcomes will replace decades-old costly hyper-hemispherical lenses for future terahertz systems in fixed wireless backbone beyond 5G and short-range see-through radar and imaging.

本项目旨在为高频太赫兹源（即谐振隧穿二极管）创建介电天线。受其最终用途的推动，该项目预计将提供用于自由空间操作的高效率、高增益、低轮廓腔天线和用于导模操作的Yagi-Uda耦合器。硅将是这两种太赫兹结构实现最高效率的关键材料。有效介质理论将实现性能、功能和可集成性，同时保持结构的简单性以获得成本效益。预期的结果将取代几十年前昂贵的超半球形透镜，用于5G以外的固定无线主干网和短距离透明雷达和成像的未来太赫兹系统。
