研究目的
To present an overview of different antenna technologies for space-based instruments and discuss the challenges and solutions for implementing these technologies at terahertz frequencies, especially for SmallSat and CubeSat platforms.
研究成果
The paper concludes that while certain antenna designs are suitable for both lower and higher frequencies, terahertz frequencies present unique challenges that require innovative solutions. It emphasizes the importance of considering the space platform and mission requirements in antenna design and highlights ongoing developments in low-profile terahertz antennas for SmallSat and CubeSat platforms. Future work will focus on developing low-profile high-gain antennas with electronic beam scanning capability at terahertz frequencies.
研究不足
The paper highlights the challenges of designing antennas at terahertz frequencies, including high Ohmic and dielectric losses, micron-scale tolerance requirements, and the need for reliable phase shifters with high phase resolution for electronic beam scanning. It also notes the limitations of certain antenna designs for space applications due to size constraints and the need for deployable antennas for CubeSat platforms.
