Designed and simulated antenna systems (patch, dipole, multi-band) using CST and HFSS Strengthened RF measurement knowledge (VNA, S-parameters, impedance matching) Worked on SDR-based signal analysis using GNU Radio and USRP Deepened understanding of wireless communication systems (Wi-Fi, Bluetooth, RF sensing) Successfully worked with the GNU Radio and USRP B210 SDR platform to analyze RF signals and minimize phase errors in drone detection systems, improving signal reliability.

Successfully designed and validated RF components, including antennas and Wilkinson power dividers, for wireless communication systems using CST Studio Suite and Altium Designer. Conducted RF characterization using VNA measurements (S-parameters), successfully identified performance limitations, and improved system efficiency. Performed detailed link budget analysis and noise figure evaluation to optimize signal quality across Wi-Fi (2.4/5 GHz) and Bluetooth frequency bands.

Selected by supervising professor to work on an industry sponsored RF project, focusing on antenna systems and electromagnetic analysis. Designed and simulated microwave structures (resonators, absorbers, antennas) using HFSS for advanced research applications. Performed electromagnetic field analysis and system-level modeling for RF and antenna systems Successfully designed, fabricated, and tested antenna prototypes operating in the S-band, validating simulation results through measurements.

Successfully executed high-precision SMD PCB assembly, ensuring reliable RF and electronic prototypes. Conducted thorough inspection and testing, maintaining product functionality and compliance. Proactively optimized assembly processes, reducing errors, and increasing efficiency. Collaborated closely with engineering teams to troubleshoot and resolve technical issues, supporting prototype development and lab validation.
