Hello everybody,
Can anybody help me through this? I've used ADS before to ascertain the characteristic impedance of a transmission line and have used waveports in CPW's.
I'm trying to coax feed (50 Ohm) a 3.6 mm wide line on air dielectric with substrate height of 27 mm. I'm using a driven terminal solution for the coax port.
I've simulated the results (0.5 to 3 GHz ) and have plotted Terminal Z, have introduced a variable with the formula for input impedance but none of the results seem stable at all.
I know what the impedance should be from Txline but I want to reaffirm that with EM simulations.
Any help is appreciated.
Ananth.
