研究成果
The paper demonstrates the feasibility of ultra-fast millimeter wave beam steering with settling times below 50 ps, suggesting its practicality for enabling novel high bit-rate multiple access schemes. The successful symbol-by-symbol steering for data streams as fast as 10 GBd highlights the potential of this technology in next-generation wireless communication systems.
研究不足
The demonstration is limited to a phased array antenna with two elements and does not explore the scalability to larger arrays or the impact of environmental factors on beam steering performance.
1：Experimental Design and Method Selection:
The experiment employs a phased array antenna with two elements for beam steering, utilizing a recently introduced time delay line for ultra-fast tunability, broadband operation, and continuous tuning.
2：Sample Selection and Data Sources:
The demonstration involves switching the beam direction between two sequentially transmitted symbols toward two receivers placed 30° apart.
3：List of Experimental Equipment and Materials:
A phased array antenna with two elements, a time delay line for the phased array feeder, and two receivers.
4：Experimental Procedures and Operational Workflow:
The beam direction is switched between two sequentially transmitted symbols, demonstrating symbol-by-symbol steering for data streams as fast as 10 GBd.
5：Data Analysis Methods:
The success of symbol-by-symbol steering is evaluated based on the ability to switch the beam direction between two receivers placed 30° apart.
