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…
