Hi everyone, and welcome to ByTechLab!
I’m an electronics engineer and multidisciplinary maker based in Poland. I built this site to document and share the technical projects I work on in my free time — from RF, through analog/digital circuits and embedded software, to mechanical creations and 3D-printed prototypes. Here you’ll find in-depth write-ups, design files, measurements, and lessons learned from real builds.
Feel free to explore the projects, leave comments, or drop me a message if you have questions or feedback!
PCB Coaxial-Fed Horn Antenna (3-7 GHz)
I have designed this antenna mainly because I need a lot of good antennas for my radar projects / experiments – I have quickly realized that my 3D Printed Double Ridged Horn Antenna that I have designed and built previously is not quick / easy…
PCB Log Periodic Antenna (0.8-6 GHz)
This post together with previous antenna related posts is a introduction to a open-source library of wide-band general purpose antennas that I’m planning to create. I will share all information’s about the design process together with detailed electromagnetic simulations results, measurements and assembly instructions so…
Balun PCB (50Ω SE to 100Ω DIFF, 30 to 6000 MHz, TCM2-63WX+)
In this post I will show you a very simple Balun PCB (TCM2-63WX+) with a transformer that converts single ended signals to differential signals. Baluns are very useful for many measurements and RF projects. RF engineering can quickly get very expensive (especially when you go…
3D Printed Double Ridged Horn Antenna (2-6 GHz)
Recently I have started a phased array FMCW radar project. I needed good antennas for this purpose but I haven’t decided which frequency to use yet. That’s why I have decided to choose a wideband antenna – I will be able to switch between different…
