How to plot Magnetic Current, specially for slotted structure, in HFSS and ADS?
I have read the post https://www.edaboard.com/showthread.php?185160-plot-magnetic-current-in-hfss&p=1116095&viewfull=1#post1116095 but unable to execute it. What are the steps for simulating it in HFSS and ADS?
I generally use ADS momentum for circuit design, not used it for Antenna, I usually use HFSS for antenna.
I was comparing the results of a microstrip resonant patch antenna designed in HFSS with ADS and EMPro (FEM only). But the resonant frequency and return loss value are completely different...
Rad. of Patch integrated with Diode switch and other lumped components in ADS & EMPro
In HFSS, we can visualise the radiation pattern of the whole structure containing patch with lumped elements, and how the values of the lumped element affects the radiation pattern.
Is it possible to simulate...
"The size of the plus pin for S-parameter port 1 is electrically large above 15.8126 GHz, S-parameters may become unphysical." - To mitigate this issue, I added 0.05 mm x 0.05 mm stub in each of the port and did 0Hz to 32GHz simulation without this warning. This problem is solved now.
But I...
I did a basic common source negative resistance oscillator using source inductive feedback and achieved |Tin|>1.3. In the nyquist plot, (I checked s2p of CE3512K2 and the NE3210S01 nonlinear model, they are giving similar traces) I am getting two clockwise encirclement @6 and @9.68 GHz (as shown...
I have simulated from 0 to 13 GHz covering DC and 2 harmonics (i.e 6 and 12GHz) in momentum, and got the following warning messages in Momentum.
(If I keep the upper frequency more than 16GHz, I am getting warning, so I kept only 2 harmonics in momentum)
"The size of the plus pin for...
Strange thing is that after setting the frequency range from DC in momentum simulation, I am still getting the warning in co-simulation

Thanks for explaining it beautifully.
Does that mean whenever I use harmonic balance simulator, I have to start from 0 GHz to maximum frequency that will be generated by HB simulator in the momentum analysis?
For this case, I am only interested to see if the oscillator is working on its...
I am designing a FET based oscillator (fo = 6 GHZ) in ADS2014. I simulated the Bias Tee sections and output matching in momentum in 5 - 8 GHz frequency range. In momentum analysis, I am not getting warnings/errors other than internal port being changed from TML to NONE calibration.
After...
