Chao Gu

I am based at Centre for Wireless Innovation, School of EEECS, Queen's University Belfast.

I specialize in wireless communication systems, with a strong focus on antenna design, smart RF technologies, and additive manufacturing for high-frequency applications. My research interests include:

Low-cost smart antennas with capabilities such as beam-switching, polarization reconfigurability, and compact design for wireless networks.

High-frequency and sub-terahertz (100 - 300 GHz) antennas for emerging 5G/6G and industrial radar applications.

3D printing and additive manufacturing for low-cost, high-performance RF components and meta-surface structures.

Reconfigurable and frequency-agile systems to improve coverage, performance, and flexibility in communication systems.

Applied electromagnetics across domains including satellite communications, mobile networks, and sensing systems.

I have led and contributed to several international research collaborations across Europe, North America, and Asia, and UK EPSRC/EU ERC funded projects. My goal is to bridge the gap between theoretical innovation and practical, scalable engineering solutions in the next generation of wireless technologies.
