Research Summary:

Professor Chou's research has consistently driven the advancement of high-gain and intelligent antenna technologies. This encompasses foundational work in electromagnetic (EM) theories, novel antenna components, passive RF components, advanced numerical EM techniques, and sophisticated optimization algorithms. His core objective has always been to prioritize application potential, ensuring that antenna and RF system technologies directly enable industrial uses and the development of robust RF systems.

Currently, his efforts are concentrated on cutting-edge antenna types, including reflector antennas, active phased array antennas, reflectarray antennas, and transmit array antennas. The aim is to fully unlock their potential and facilitate advanced applications.

Over recent years, Professor Chou's primary research activities have centered on the following key areas:

 

Key Research Trajectories:

  • Next-Generation Antenna System Enablement: Developing advanced techniques for realizing vast antenna systems, including rapid analysis and numerical EM methods, sophisticated antenna design and realization algorithms, expanding application scenarios, and pioneering cloud-based optimization for antenna networking and intelligent operations.

  • Fundamental EM for High-Gain Antennas: Building robust electromagnetic foundations for high-gain antennas through both time- and frequency-domain EM theories. A key goal is to develop theories based on the Uniform Geometrical Theory of Diffraction (UTD) architecture, which precisely describes diffraction mechanisms for localized antenna design.

  • High-Gain Antennas for Future Communications: Focusing on high-gain antenna technologies vital for next-generation mobile communications, satellite communications, and specialized applications. Significant emphasis is placed on developing intelligent operation mechanisms to meet dynamic application needs, with a clear trend towards millimeter-wave and sub-terahertz (Sub-THz) frequency bands.

  • Advanced Antenna Measurement and Characterization: Enhancing techniques for measuring, signal decomposition, and suppressing/decomposing multipath interference in extensive antenna systems. The objective is to overcome spatial limitations in measurement environments, ultimately integrating measurement systems with numerical software to enable comprehensive characterization and optimal design of antenna systems in simulated application scenarios.

  • Integrated Antenna Systems for 5G/B5G/6G: Developing antenna systems, Massive MIMO systems, and innovative antenna solutions for 5G, Beyond 5G (B5G), and 6G applications in next-generation mobile communications (covering sub-6 GHz, millimeter-wave, and Sub-THz frequencies). A major focus is on modularization technologies like Antenna-in-Package (AiP) and Antenna-in-Module (AiM), integrating antennas directly with RF ICs, with active antenna array systems being a primary long-term goal.

  • Tracking and Radar Systems: Advancing tracking antenna systems and radar systems for critical applications in communications and target detection for Low Earth Orbit (LEO) satellites, Unmanned Aerial Vehicles (UAVs), and autonomous vehicles.
