Add Another Log To The Pile (Log Periodic Antennas, Pt. 2)

May 12, 2025May 12, 2025 GadiAntenna, CEM, CST, Engineering, FEM, RF, SimulationLeave a Comment on Add Another Log To The Pile (Log Periodic Antennas, Pt. 2)

We left off in the previous post trying to figure out a slightly more rigorous approach, to connect together two antennas, resonating in adjacent frequencies. Let’s recall: The designer may (or may not) choose a point with higher impedance. This…

Why Think If You Can Log? (Log Periodic Antennas, Pt. 1)

May 11, 2025May 13, 2025 GadiAntenna, CAD, CEM, CST, Engineering, FEM, RF, SimulationLeave a Comment on Why Think If You Can Log? (Log Periodic Antennas, Pt. 1)

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…

FEM Failures, Finale. Featuring Dolphins And Whales!

July 25, 2024July 25, 2024 GadiAntenna, CEM, Eigenmode, Engineering, FEM, Programming, Python, RF, SimulationLeave a Comment on 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,…

No (Open) Source To Rely On – Finite Element Adventures, Chapter VI

April 9, 2024January 15, 2025 GadiAntenna, CEM, Engineering, FEM, Python, RF, SimulationLeave a Comment on 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!

How To Make A Cactus – Multi Band Antennas

June 5, 2023June 5, 2023 GadiAntenna, CAD, Electronics, Engineering, FEM, RF, SimulationLeave a Comment on 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

May 30, 2023May 30, 2023 GadiAntenna, CEM, Electronics, Engineering, RF, SimulationLeave a Comment on 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…
