Yes! Exactly!
I simulated the antenna at the HFSS and I would like to incorporate its electrical characteristics (s11) in ADS to simulate the entire system. The problem is that I do not know how to create a two port block in ADS based on the s11 parameter from HFSS.
Perhaps you could send me...
Hello all,
I am trying to simulate the frequency response of a simple rectifier using HB in ADS (Vdc x Freq). I have set the sweep variable to be the frequency of the power source of the circuit. When I perform the simulation, however, I get a constant dc output voltage which does not depend on...
Hello! Thanks for answering!
I thought about this, but from HFSS I can get only the s11 parameters. How I can make a two port block out of only s11 parameter data?
Thanks again!
Hey!
Did you manage to solve this issue? I am having the same problem now: I designed an antenna at HFSS, but I do not know how to build a two port block at ADS based on the s11 parameters from HFSS....
Thanks!
Dear all,
Anyone here knows how to sweep a variable of a model in ADS? I would like to simulate the impact of the saturation current of a diode in a rectifier at the output voltage. In this way, I would need two variables (RFPower and SaturationCurrent) and have a plot of VoutxRFPower for...
Another way to see this problem is how to implement an ac source with a frequency dependent impedance. This impedance of the ac source would be, of course, the same impedance of the antenna obtained from HFSS.
Any idea there??!
Thanks!
Hello,
I have simulated a dipole antenna at HFSS. Now, I would like to use it in a design at ADS. In this way, I would like to have a two-port block that would mimic the impedance frequency dependency of the antenna. Probably at port 1, the impedance should be always equal to 50ohms, while the...
Perhaps I did not explain well my problem...
I have a UHF dipole antenna with an impedance of 46 -j0.8 ohms for energy harvesting objectives at 868MHz. Before connecting it to the rectifier, I have to use a balun, which s-parameters I can get from the supplier (3 port measurements from Mini...
Dear all,
I would like to make a full simulation of a double rectifier in ADS. The problem that I am facing now is to connect a dipole antenna model (1 port - s11 parameter) to a ballun (3 port device). How should I connect this two components? Should I excite both input balanced ports of the...
Dear all,
I have been trying to extract the input impedance (from s11 parameters) of a simple single stage rectifier as a function of input power (-20dbm to 10dbm). Does anyone here knows how to couple these two measurements?
I tried to use Harmonic Balance with the small-signal option...
Hello ! Thank you for your replies!
I send in attachment the HFSS file. After waiting 22min the simulation was over, but with an error:
"[error] Mesh leak is found for (2) of bodies: (Au_Feed) (Au_Feed_1) (5:02:52 PM Apr 20, 2013)"
This can be due to the thickness of the top Gold layer...
Hello all,
I am trying to simulate a simple UHF printed dipole antenna. Due its size (lambda/2=17cm), after some minutes of simulation the number of tets go to more than 4 million!
Even if after adding a mesh operation to limit the number of elements, the simulation still uses million of...
