Research Summary:

 In the past history of Prof. Chou’s research activities, significant efforts have been cored on the realization of high-gain, smart antennas and the required technologies including fundamental electromagnetic (EM) theories, antenna components, passive RF components, numerical electromagnetic techniques and the optimization algorithms. The objective considers the application potentials as the core to develop the antenna related technologies and enable the industrial applications. Current efforts focus on the reflector antennas, phased array antennas, reflectarray antennas and transmitarray antennas with major works to drive its potential and advanced applications. The major activities in recent years focused on the following subjects:
(1) The required advanced techniques to realize the extremely large array antennas, which include the fast analysis/numerical EM techniques, antenna design/realization algorithms, scope extension of application scenarios, and the cloud-based optimization of antenna networking and smart operations.  
(2) The buildup of electromagnetic foundations for the high-gain antennas, which includes time- and frequency- domains EM theory. The goal is to build up the foundation based on the architecture of Uniform Geometrical Theory of Diffraction (UTD) to provide the diffraction mechanisms that allow one to design the antennas by considering the local diffraction phenomena.
(3) The technologies of high-gain antennas for the next generations of mobile communications, satellite communications and special applications. The major efforts are to develop the technologies for the smart operations of high-gain antennas to fulfill the needs of dynamic applications. The development trends tend to utilize the millimeter wave frequency bands and their technologies.
(4) The measurement, signal decomposition and multipath suppression/decomposition techniques to characterize the extremely large antenna systems. The objective is to overcome the limitation of measurement system in a limited space. The final goal attempts to integrate the measurement system into the numerical software so that the overall characterization of antenna systems simulating the application scenarios can be performed to provide the reference in the design stages.

(5) Antenna system, Massive MIMO system, smart antenna system for 5G/B5G/6G applications of next generation mobile communications (at both sub-6 GHz, millimeter wave frequencies and Sub-THz). Modularization technology to integrate antenna and RF IC to form an antenna system in package (Antenna-in-Package, AiP and Antenna-in-Module, AiM).

(6) Tracking antenna system and radar system for the applications of UAV and unmanned vehicles in the communications and target detection.
