Senior Antenna / Array Design Engineer
Location: Chennai, India (IN)
Description
- Own antenna/array designs from topology selection and modeling to prototyping, tuning, chamber validation, and release to production.
- Translate system-level targets (coverage, link budget, EIRP/ERP limits, form-factor/cost) into antenna specifications.
- Build parametric EM models and correlate simulation to measurement; maintain analysis scripts and golden test procedures.
- Partner with ME/EE/NPI to drive manufacturability, yield, and root-cause investigations.
Requirements
- B.Sc. in Electrical Engineering (EM/RF focus); MSc/PhD preferred.
- 5+ years end-to-end antenna design (concept → EM simulation → prototype → validation → manufacturing handoff).
- Hands-on experience with two or more: patch arrays, horn arrays, parabolic reflectors, dipole/monopole arrays.
- Proficiency with full-wave EM solvers (CST preferred; HFSS/FEKO or similar acceptable).
- Strong MATLAB and/or Python for array synthesis, optimization, and data reduction.
- Lab proficiency: VNA (SOLT/TRL), OTA/anechoic measurements (gain/efficiency/patterns/ECC), fixture de-embedding.
- Solid grasp of array fundamentals: mutual coupling, scan loss, grating-lobe control, polarization/isolation.
- Practical RF PCB layout literacy (stack-up, feeds/matching, grounding/shielding) and DFM/tolerance awareness.
- Clear documentation and effective cross-functional communication.
Nice to have-
- Phased-array design (active/passive networks, phase shifters, codebooks; Butler/Blass feeds).
- Wideband and dual-polarized elements; radome & mechanical co-design.
- RF test automation (Python/PyVISA/LabVIEW/C#) and data/report pipelines.
- Regulatory/OTA familiarity (FCC/CE, CTIA-style OTA), basic EMC considerations.
- Familiarity with wireless communication standards, especially Wi-Fi 6/7 (802.11ax/be) and implications on antenna design
- Understanding of MIMO systems, beamforming principles and implications on antenna design
