About Urja Dart

Urja Dart is building
far-field microwave wireless power transfer (WPT)
systems: transmitting energy through directed microwave beams and receiving it through high-efficiency antenna /
rectenna
systems.

We are developing a microwave-to-rectenna prototype toward a long-range terrestrial demonstration. Power-electronics capability is already in the team; we are seeking a co-founder to own the
microwave, RF, antenna, phased-array, and end-to-end WPT link
.

The current founder is a repeat SpaceTech entrepreneur who previously received a $2.5 million pre-seed funding commitment, bringing prior fundraising experience, investor access, and execution perspective to Urja Dart.

What You’ll Build

You will lead the complete microwave WPT journey:





Microwave source → RF power amplification → RF distribution / phase control → transmitting antenna or phased array → directed beam → free-space propagation → receiving antenna / rectenna → usable DC power

Key responsibilities:
- Define WPT architecture, frequency, link budget, aperture sizing, beam width, power-density and end-to-end efficiency targets
- Develop microwave transmitter systems: RF sources, PLLs, PAs/SSPAs, RF power combining, filters, couplers, feed networks, thermal and protection systems
- Design transmitting antennas, high-gain arrays, phased arrays, beamforming and electronic beam-steering systems
- Lead beam pointing, phase calibration, polarization, sidelobe control, radiation-pattern testing, and transmitter-array optimization
- Design receiving antenna and rectenna arrays: antenna elements, impedance matching, RF combining, harmonic control, receiver capture, array coupling, and misalignment tolerance
- Model propagation, beam spread, path loss, pointing error, multipath, safety, RF exposure, a
