Mohan Ram

RF Engineer specialising in passive microwave components, antenna systems, ferrite devices, and EM simulation with a full-stack track record from simulation through microfabrication, VNA characterisation, and documented design reports. Proficient in ANSYS HFSS, CST Studio Suite, COMSOL Multiphysics, and AWR Microwave Office; hands-on with photolithography, wet etching, sputtering, gold plating, and probe-station measurements. Experienced in Smith Chart analysis, impedance matching, S-parameter characterisation, and correlating fabricated hardware against simulation.

Keen to grow into RF front-end and defence microwave systems.

Junior Research Fellow at BITS Pilani, Hyderabad Campus – Lambda (2026-07 – Present)

• Simulating waveguide and microstrip circulators in COMSOL Multiphysics; resolved meshing and convergence challenges for ferrite-loaded structures to achieve accurate eigenmode and S-parameter results.
• Managing end-to-end microfabrication of microstrip circulators: photolithography (laser writing on photoresist), wet chemical etching, sputtering, thermal and e-beam deposition, and gold plating.
• Characterising fabricated passive microwave components on a probe station; correlating measured S-parameters with simulation and preparing design verification reports.
• Collaborating with research team on design reviews and technical documentation; contributed to iterative design cycles driven by measurement–simulation correlation.

Project Intern at BITS Pilani, Hyderabad Campus – Lambda (2026-02 – 2026-06)

• Designed and simulated array antennas and couplers in CST Studio Suite and AWR Microwave Office; performed impedance matching using Smith Chart analysis and validated port S-parameters and radiation patterns.
• Executed microwave measurements on RF DUTs – antennas, couplers, and circulators – using VNAs, spectrum analysers, and signal generators; applied calibration, embedding, and de-embedding techniques.
• Documented test procedures and measurement results; communicated findings in team design reviews.

RF Antenna Designer Intern at Wilma Communication Groups (2024-11 – 2025-02)

• Engineered MIMO antenna systems and FSS structures in ANSYS HFSS; optimised gain, port isolation, and ECC prior to fabrication.
• Executed full simulate–fabricate–measure cycle: photolithography, wet etching, and VNA characterisation; prepared measurement reports correlating hardware results against simulation.
