What I Work On
Antenna & RF Design
- Custom antenna designs from 400 MHz to 8 GHz in high-volume production
- RF front-end chains with triplexer/diplexer integration for multi-radio coexistence
- Design-for-integration strategies in space-constrained, near-metal environments
Testing & Validation
- CST simulation, VNA characterization, anechoic chamber pattern measurements
- S-parameter and isolation analysis for regulatory compliance
- Power meter measurements and spectrum analyzer debugging
AI & Automation
- AI tool integration for measurement parsing and test automation
- Python tooling for antenna data visualization (RFlect)
- Engineering workflow optimization with LLM-assisted productivity
Wireless Protocols
- WiFi (2.4/5/7 GHz), BLE, UWB, 900 MHz ISM
- LTE, LoRa, GNSS
- Wireless power: Qi, AirFuel, NFC
