Re: Convergence value

My experience is that when simulation reaches a plateau around 35 dB, something is not right in the setting of the simulation. I become really doubtful when spurious oscillations occur. May be you should try to block the simulation at 1.e-3 and see if things are consistent, I may be wrong.

Negative impedance for an antenna at 1 GHz (and 50 Hz)

Hello. I am running a simulation where an antenna is made of an external wire and a coaxial wire. These two wires are connected through an active and passive lumped ports. Each port has a resistance of 50 ohms. The antenna is approximately 190 mm long. The frequency that I use is is 1 GHz. The passi...
