A tale of wearables and things I’ve had a love-hate relationship with flexible printed circuits (FPCs). On the one hand, terrible to manufacture, solder and maintain. On the other? They are so cool. Extremely tough for RF designs, due to…

How To Make A Bad Network Analyzer
Introduction Avast ye lab lubbers and radio farers! For reasons that will remain disclosed now, I have been getting into designing some measurement instruments. And what better one to talk about than the most coveted item for every radio engineer.…
FEM Failures, Finale. Featuring Dolphins And Whales!
The final chapter is upon us. But will a solution be found? Stay tuned, to find out more. We left off with a seemingly singular solution. Who knew, that the coaxial cable, of all… It should be the simplest one,…
Order, Please. (FEM Adventures Pt. 3)
One step closer to insanity, one step further in finite element computation.
Time, Harmonics And Everything In Between
Chapter two of this test of will. This time, with singularities!
No (Open) Source To Rely On – Finite Element Adventures, Chapter VI
The first part of my open-source FEM Eigenmode solver adventure. No happy ends, promise!
Ancient, Overweight, Yet Alive And Kicking
Benchmarking my new(is) P920!
(S)tay True, (S)tay Humble
Every once in a while, I learn that even if I think I knew a subjet to it’s fullest, there is something I missed. In this occasion, it’s scattering parameters, commonly known as S-Params. It’s not a “subject”, per-seh, barely…
How To Make A Cactus – Multi Band Antennas
In the previous post, I discussed the fact that an Antenna should be designed from its stem, namely, its feeding point. I wouldn’t go as far as to say it’s easier to design this way, but it’s definitely better. I…
Grounded, Again
There are a lot of weird articles out there. Out of respect, I’m not going to reference anything now, but if you’ve been around a bit, you know what I’m talking about. Specifically, in the field of Antennas, some person…
