All projects
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…
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…
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…
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…
In this short post I will show you a very useful accessory – Rigol DL3021A 4mm Banana Jack Adapter. The stock configuration of the Rigol DL3021A uses screw terminals which are quite painful to use and are not compatible with 4mm banana plugs of course.…
Recently I have built a Bambu Lab X1C Fume Filtering System which is based on Xiaomi air purifier (link) . It came out that this air purifier works perfectly – there’s zero smell & PM2.5 sensor shows the value of 0 (when printing with ABS…
