About Florian

Radio-frequency / antenna engineer and PhD, specialist in the design of high-performance antennas for constrained environments and critical applications (IoT, embedded systems, defense).

I design, simulate, prototype, and validate antenna systems from 30 MHz to 10 GHz, including miniature, multiband, super-directive, CRPA/ESPAR antennas, and integrated solutions. I favor PCB printed antennas (€0). I can also integrate and adapt your antennas or off-the-shelf antennas. I can follow and advise on electronic design to ensure proper RF operation (antenna placement, RF front-end choice, ground plane and via placement, RF line sizing, ...).

My approach combines scientific rigor, field experience, and system vision for measurable real-world performance, from concept to industrialization.

🔹 Antenna Design & Optimization
– Antennas from 30 MHz to 10 GHz
– Miniature and multiband antennas
– Controlled radiation pattern antennas (CRPA, ESPAR)
– Antenna matching

🔹 Electromagnetic Simulation & RF Studies
– 2D & 3D Simulation
– Coupling studies, context, and mechanical integration
– Optimization

🔹 Prototyping & Validation
– Antenna and RF board prototyping
– VNA measurements
– Simulation / measurement correlation
– Documentation

🔹 RF Architecture & System Integration
– Definition of RF architectures
– RF board design
– Industrialization support and field testing
