Hi all,
I am wondering if someone could take look at my CPW HFSS project and explain to/show me why it is not working. I am simply trying to simulate a high-Q, 2-lambda resonator, whose resonant frequency is 2GHz.
My results do not show any well defined resonant peak or a high quality factor...
In HFSS, you normally solve cavity resonators with a Eigenmode Solver solution type. In this solution type you do not have to specify wave ports. I am not 100% sure but I believe there is something similar in CST.
Thank you very much for your reply volker. Does Sonnet also illustrate the vector field lines? That is one of the reasons I chose HFSS, but if it makes more sense to model this in Sonnet I would be willing to learn.
To calculate the Q, I am just dividing the resonant frequency over the bandwidth from the S21 parameters. According to some papers on the subject, it is possible to get a loaded Q of well over 10,000.

Thanks...
I am using that that, but I am wondering if there is anything else. I should be getting an extremely high Q-factor for my simulations, but have not had any luck so far.
Hi,
I was wondering if anybody has resources or examples of how to simulate superconducting circuits in HFSS. Anything specifically dealing with modeling of superconducting resonators would also be much appreciated.
Thanks for the continued support!
Thanks again ferdows, I will definitely check out the paper. I am not designing an antenna, I just want my meandering CPW structure to resonate with a high Q.
Hi,
I am simulating a CPW in HFSS whose dimensions are: width = 50 um, gap = 30um, and substrate height = 430 um. Using the suggested port sizing from Ansoft ( Height = 4h, Width = 3(2g +w) ) gives me a port impedance of ~8 ohms. The only way I currently know of increasing port impedance is to...
