Take ownership of RF!
Radio Frequency design is often viewed as the "dark arts" of engineering. It can feel mysterious, overcomplicated, and intimidating to integrate into a new product, but it should not be that way.
​
My vision is to provide practical consultancy services that focus on delivering the specific solution you seek along with complete ownership of the results. Because I utilize my own open source simulation software, I do not just provide a final design. I provide you with the actual tools and simulation files you need to take the project forward independently.
My goal is to demystify the process and give you full control over your own technology.
About Me.
My name is Robert Fennis. I am a 33 year old Antenna Engineer from the Netherlands.
In 2019 I completed my masters degree in Telecommunication Engineering at the University of Twente. After that I worked for 5 years as an Antenna Engineer at Thales Nederland B.V. in Hengelo. Here I worked on systems such as the Smart-L, NS50, Stir 1.8 and research projects.
​
In 2024 I started working as an Antenna Engineer at the European Space Agency (ESA) in Noordwijk the Netherlands. There I helped with projects such as Rose-L, Sunrise, GENESIS and other smaller research activities.
In 2025 I started working on the free and open-source RF Finite Element solver EMerge. That and the Physical Optics solver Optycal are available on my website www.emerge-software.com.
​
I use EMerge to run my EM simulations which means that I do not need to charge additional fees for commercial solvers like CST or HFSS.
Specialties
Phased Array Antennas
Patch, waveguide, vivaldi and more.
Design and development of active and passive phased array antennas. My background includes patch arrays, open ended waveguides, and Vivaldi structures. I bring years of experience from Thales to help you build high performance array systems for any application.
Antenna Radomes
Space frame radomes, Radome panels, A/C-sandwiches
Comprehensive design and optimization of antenna enclosures. I handle material selection and analyze the impact of the radome on pattern integrity and boresight error. By optimizing the geometry and dielectric properties, I ensure your antenna maintains peak performance even in the most demanding environmental conditions.
Computational Electromagnetics
Finite Element Method and Physical Optics
Technical support for the development of electromagnetic simulation software. I focus on the practical implementation of the Finite Element Method and Physical Optics.
Passive microwave/stripline components
Microstrip/stripline filters, power combiners an impedance matching structures
Design support for passive RF and microwave components. I can help you develop and simulate stripline filters, impedance matching circuits, and other passive structures to complete your hardware design.
