About

Jiantong Li is a researcher specializing in millimeter-wave (mmWave) antenna engineering, with a particular focus on 60 GHz systems, phased array design, and on-chip antenna technology for next-generation wireless communications. His work addresses some of the most pressing challenges in 5G and beyond-5G hardware development, including radiation efficiency limitations and the complexities of high-frequency fabrication and measurement. Among his most significant contributions is the development of a low-cost vertically integrated antenna array operating at 60 GHz achieving 85% efficiency, a notable advancement given the severe path losses and miniaturization constraints of this frequency band (24 citations). Equally impactful is his pioneering work on MEMS-suspended on-chip antenna arrays, which fundamentally improved radiation efficiency beyond 80% at 60 GHz — surpassing the long-standing 50% barrier that has constrained silicon-based mmWave systems (22 citations). Li has also contributed to advancing antenna measurement methodologies, developing robotically controlled pattern measurement strategies to minimize alignment errors inherent in mmWave characterization. Collectively, his research bridges critical gaps between theoretical antenna design and practical, scalable implementation, making meaningful contributions to the engineering community working on compact, high-performance wireless systems.
