Simulating 433Mhz Dipolo with ADS

[tomars]

I need help for this.

I made two simulation, using one pin and grond, and one +pin and one - pin
Result is more different.
What is the right method ?
Using one pole and Grond, i see little activity on bottom pole, on momentum Visualization, animation.

P1 P2 are +/- pole
sim2 is P1 + GND
sim2_2 is P1+ P2-

The difference between cconcrete to 0mm, and 1mm from the PCB is really a lot.
It is a really too unstable situation.
Maybe is better if i make antenna on a single layer, opposite to concrete.

On test:
PMMA + copper + fr4 + copper + fr4 + air + concrete
Changing air thickness, it seems that it is less unstable.

Yes, correct. Distance helps.
