Electrical and Computer Engineering Student | Antenna and FMCW Radar Research

I keep coming back to radar, from building compact antenna hardware to collecting hand gesture signals with a mmWave sensor. I also help wire up the flight controls on model aircraft.

Selected projects

Circularly Polarized Low RCS Coaxially-Fed Antenna (ISM Band)

Developed a circularly polarized antenna integrated with a custom-designed unit cell (metasurface) for radar cross section reduction. Achieved up to 15 dB RCS reduction at the target frequency while maintaining high radiation efficiency and polarization purity, using CST Studio Suite for full-wave electromagnetic simulations.

Hand Gesture Recognition via Micro-Doppler Signatures

Configured a Texas Instruments IWR1443 mmWave radar to capture micro-Doppler signatures, built a Python signal processing pipeline for time-frequency spectrograms with clutter removal and noise filtering, and trained a machine learning model with 92% prediction accuracy. Current focus is expanding the dataset and refining the neural network architecture to exceed 95% classification accuracy.

Fully Integrated FMCW Radar Frontend (2.4 GHz)

Designed a complete 2.4 GHz FMCW radar hardware frontend with a low-noise amplifier, power amplifier, branchline mixer, coupler, and antenna. Optimized the board layout to 7.5 × 4.5 mm and conducted full-wave EM co-simulations. Planned next steps include prototype measurements, raw data acquisition, and machine learning-based target classification.
