Re: 900MHz Yagi simulation

I have some progress! I used cylinder primitive instead of wire and square. Probably the square (not hollow) element is very different.

The simulation with the cylinder achieves almost the same result as the real measurement.

900MHz Yagi simulation

Hello, I would like to re-simulate antenna that I've simulated in 4nec2. There I have good SWR. However in openEMS I do get different impedance. I changed the mesh several times, played with the boundary conditions (MUR, PML) and also with the elements shape (cylinder vs square). I did notice that t...

Re: Impedance of Half-Wave Dipole

Since this is pretty good example, I'm attaching a slightly modified dipole2.m (not 0.48 ratio tough...).
The commented out lines allow for rectangular shape of the antenna.
MUR changed to PML_8.
S11 is also plotted.
