About
Nima Ghalichechian is a prominent researcher specializing in millimeter-wave (mmWave) antenna design, on-chip antenna arrays, and advanced measurement systems, with particular focus on addressing the efficiency and integration challenges inherent to next-generation wireless communications. His work has made substantial contributions to 5G and beyond-5G technologies, most notably through innovative solutions to the longstanding problem of low radiation efficiency in silicon-based on-chip antennas. His landmark 2021 papers — demonstrating a vertically integrated 60 GHz antenna array achieving 85% efficiency (24 citations) and an on-chip MEMS-suspended phased array surpassing 80% radiation efficiency (22 citations) — represent fundamental advances over conventional designs that typically fall below 50% efficiency. Ghalichechian has also pioneered precise robotic antenna measurement systems capable of operating from 6 to 110 GHz, enabling more accurate mmWave characterization across near- and far-field conditions. His more recent explorations into silicon carbide (SiC) substrates for on-chip dielectric resonator antennas, achieving 91.5% efficiency at temperatures up to 400°C, signal a forward-looking commitment to electronics capable of performing in extreme environments. Collectively, his body of work reflects a researcher systematically pushing the boundaries of mmWave antenna performance, fabrication, and measurement.
