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…
Building Bridges Pt. 1 – How Would You Solve This?
Trouble with computational geometry. How would you solve it?
RADAR Pt. 2 – A Practical Explanation
A practical example of how pulses are transmitted and received. A bit about modulation, demodulation and avoiding everything that is mildly complicated
Short Excerpt About Open Subjects In De-Embedding
Just a bit about the underlying assumptions of de-embedding schemes.
Ports – From 3D to 0D
Disclaimer: This issue is boring. Not only because it has nothing to do with Cyber, AI, machine learning, etc. (nor do most of the things I do and write about). It’s boring because it has to do with only one…
DXF Import In Octave
Nothing fancy, but I programmed a tool to import DXFs into GNU octave. Should be simple enough to convert to MATLAB, if necessary. Mainly I did it in order to integrate some of the work I do in KiCAD to…
QUCS-S: Return Of The OpenSouce!
Another Linux user open wound: For ages I have been stuck without proper circuit simulation in Linux. I don’t define myself a power-user (only as a super user, but only when I run sudo) as I run Ubuntu, but that…
Obsessive, Compulsive, Yet Hardly a Disorder
So this has happened to me more times than I can remember. Somebody tosses a piece of junk or another out on the street. I pick it up, hoping that this time it will work “out of the box”. Sometimes…
The Perils of Port Extensions
This post concerns a much more simplified version of the previous one. Last time we dealt with an arbitrary length line, with an unknown characteristic impedance. For that matter, a double length line de-embedding structure was suggested. In this post,…
