Role Overview and Responsibilities:
Dhruva Space is seeking an experienced Antenna Engineer to design, analyze,
develop and characterize high-performance antenna systems for satellite and ground-segment applications. As part of our advanced RF and space systems team, the engineer will work on space borne, user-terminal, and ground-station antennas operating across L, S, C, X, Ku, Ka, and mm-Wave bands. This role supports mission-critical communication, navigation, and payload systems and requires strong expertise in electromagnetics, antenna theory, and space-qualified design practices.
Key responsibilities include, but are not limited to:
- Design, develop & characterize antennas for satellite payloads, user terminals, and ground stations.
- Work on diverse antenna types including patch, horn, reflector, array, helical, waveguide, and phased-array antennas.
- Perform full-wave electromagnetic simulations using tools such as COMSOL, CST, HFSS & FEKO.
- Optimize antenna performance parameters including gain, efficiency, axial ratio, polarization purity, sidelobe levels, and beam coverage.
- Support phased-array and beam-steering antenna architectures for satellite communication systems.
- Conduct antenna prototyping, testing, and validation in anechoic chambers and near-field/far-field test ranges.
- Analyze antenna performance under space environment constraints including thermal, vacuum, vibration, and radiation.
- Collaborate closely with mechanical, thermal, RF, payload, and systems engineering teams for antenna integration.
- Support link budget analysis and system-level RF performance evaluations.
- Prepare detailed technical documentation, simulation reports, and test results.
Candidate Requirements:
- Bachelor’s or Master’s degree in Electronics & Communication Engineering, or Electrical engineering (or) equivalent.
- Strong foundation in electromagnetics, antenna theory, and microwave engineering.
- Proficiency with electromagnetic simulation tools such as COMSOL / CST / HFSS / FEKO / GRASP.
- Experience using RF measurement equipment including VNA, spectrum analyzers, and power meters.
- Ability to take antenna designs from concept through testing independently and validation.
- Strong analytical, troubleshooting, and problem-solving skills.
- Proficiency in feed network design.
- Experience using MATLAB or Python for antenna analysis, optimization, and post-processing.
