About Company

Antenna Engineer – Helios RF Systems
• Designed, simulated, and tested wideband and narrowband antennas for aerospace and telecommunications sectors using CST, HFSS, and FEKO.
• Led the end-to-end development of airborne blade and conformal antennas, integrating electromagnetic and mechanical constraints into the design cycle.
• Modeled antennas on complex platforms and validated VSWR, gain, and isolation performance across mission bands.
• Built and tested custom antenna prototypes in anechoic chambers using VNAs and near-field measurement setups.
• Used MATLAB to develop custom post-processing tools for evaluating antenna radiation characteristics, polarization purity, and near/far-field transformation.
• Collaborated with systems engineers and clients to define performance metrics and environmental constraints based on project specifications.
• Interfaced with regulatory compliance teams to align designs with FCC and MIL-STD emission requirements.
• Created test plans and validation documents for military antenna qualification and production readiness.
• Assisted firmware engineers in integrating RF switching and control logic into embedded systems using SPI and I2C protocols.

RF Engineering Intern – SkyWave Microsystems
• Developed and optimized load-pull setups for PA design verification, enabling high-efficiency tuning under real-world mismatch conditions.
• Transferred GaAs MMIC designs from legacy nodes to a modern 0.15μm PDK, ensuring minimal parasitic drift and maintaining matching networks.
• Conducted impedance matching and bandwidth optimization of S-band LNAs and PAs using ADS and Momentum tools.
• Generated simulation testbenches and yield analysis reports to support production qualification.
