HFSS material setting
I assume the number you are talking about is 10+j*0.1. Therefore,
Relative dielectic constant =10;
Loss tangent=0.01;
which are correct.
But the conductivity not only depends on the imaginary part of complex permittivity, but also realted with the operating frequency...
Hi wlcsp,
Lumped ports excite a simplified single-mode field excitation assuming a user-supplied Z0 for S-para Referencing. There is and only is one terminal line per port. You cannot define two or more.
2. Since only single-mode is excited in lumped port, it is not appropiate for excitations...
At present, I have been trying to simulate single/coupled open-loop resonators in HFSS. But I encounter several problems on how to set ports on the coupled open-loop resonators and input/output tapped single open-loop resonator in HFSS for EM simulation.
For coupled resonators, when I try to...
Hi all
I am not studying microstrip circuit design. By using HFSS, I set a micrpstrip line and want to obtain its impedance as well as its effective dielectric constant. However, I have been using HFSS for only 4 days, and do not know how to do it. I think I have to use wave port. Should I use...
I could obtain the physical dimensions directly by ansoft deisgner now. Besides, by using parameter sweep in sonnet, I also can calculate them step by step now.
But I still don't quite undetstand without software's assitance how I could analytically calculate Spacing for an interdigital filter...
Hi all
I am a freshman in interdigital designing. and now I need to design a microstrip interdigital bandpass filter. I chose symmetric structure with tapped-line input.
I have got even- and odd- mode impedance, but am in trouble obtaining the physical dimensions- width, spacing, length. I...

Hi rautio
Thank you so much! Your advice and attached file enormously helped me.
I got one question for the Eeff. Though there is only one dielectric for stripline, there is air above lines. So should I consider there are two dielectrics-air and substrate...
coupled stripline hfss
Hi,
I am a newbie of HFSS. I wish to simulate a pair of coupled stripline, and extract its even- and odd- mode character impedances and relative dielectric constants. how can i set up the simulation in HFSS?
Thanks!
Hi all,
I have been recently trying to simulate a pair of coupled striplines in HFSS. I tried but failed to obtain the coupled lines' characteristic impedance and relative dielectric constant for even-mode (Zoe, Epsilon-re)and odd-mode (Zoo, Epsilon-ro) excitations.
I set two wave ports on...

Hi all,
I have been recently trying to simulate a pair of coupled striplines in HFSS. I tried but failed to obtain the coupled lines' characteristic impedance and relative dielectric constant for even-mode (Zoe, Epsilon-re)and odd-mode (Zoo, Epsilon-ro) excitations...
