Hi jonny1 I dont have access to hfss right now but I can recommend you one thing. Check the hfss tutorial for waveguide simulation. May be you will find what is going wrong. Example shows how to excite waveguide,& do port setttings. You will findwave guide tutorials in this forum or google it.
Hi all, I'm a new guide in the LTCC design and need to desing a filter using this material recently. I don't know how to de-embed these values using the hfss. I have try to model the capacitor and de-embed its value, but the value is big different when compare to the general formula i.e. E0Er*A/d. Help Any input or example to de-embed L a

Hello. Perhaps someone could help me, at least guide me into which tutorial to look at.. :/ I have designed a small patch antenna, with a resonance frequency of approximately 6.5Ghz. I cannot change its dimensions, since this is the largest antenna i am allowed to use in my application . However, the antenna ne

Hi everybody! i'm new to hfss. I need to simulate a parallel plate capacitor with air as dielectric. I've designed it according to the hfss guide i've found on the web, but i would like to calculate the S and Y parameters for this structure (i think i'm gonna post the hfss file as soon as i'm home). How do i have to excite (...)

Hi everyone, I am trying to design a spiral inductor on hfss v11. the manual i have is v10. I have probs in assigning lump ports and also excitation. Does anyone has the v11 manual (adv notes) for this or could someone pls guide me. I dont have points yet. Pls send via email to lina_7572(at)yahoo.com Thanks
hi, for IE3D u should download manual (evaluation version) from zeland website. For hfss lot of tutorials are available in this site.
Hi, I am trying to simulatte ungrounded-CPW in hfss. Center conductor width is 94um and the gap 62um. Based on the recommendation of hfss CPW tutorial guide, the size of the port has been decided to be width of 654um and length more than 2000um. And I choose the option, solve ports only in the setup expecting the port impedance, Zpi, Zvi (...)
a simple question about the radiation calculation in hfss. If the antenna we designed has 2 or more ports, with various feeding amplitude and phase combinations, how can we guide the hfss to calculate the radiation pattern. I am using the driven terminal solution types. Thanks.
Hello everyone, I am trying to design spiral inductor by following the silicon spiral inductor example from the hfss guide. But I am getting the following error while analyzing the design: ? Port refinement, process abc3d: there are no boundaries to define ?p1? correctly. This may be due to incorrect material definitions for those objects tha
Hello everybody, I'm looking to find the equation of the impedance of a port in a Rectangular Wave guide in hfss. Fo example, when i simulate a RWG i use two WavePorts non normalised at 50 Ohms, and then, hfss gives me the impedance Zo (depended of the frequency). I'm wondering what is the exact formula the software use ?? Thanks a lot :)
Thanks! Menuitems of hfss\mesh operations\.. are not what I want to discuss here.. I have tried below actions: 1. Adding a point object on the surface of the object I want to mesh. The point can't be a model object. It doen't works. 2. Draw a sheet (e.g. rectangle) on the surface. If it is assigned non-model object property, th
man u shoulg have a look inside the forum.u will find a lot but i m sorry that u have no enuf points to download a single file. it is my advise that got through the guide book inside the toolbar HELP within the software hfss. if u have the software Lauch it and click HELP.U will find each and every thing about hfss. Hope that answers (...)
hey what kinda waveguide are you talking about exactly? the tutorial for hfss gives a guide for T-waveguides... though not at your frequency.. but it'll give you a start.. regards wiztronix

Hi everybody, I wanna co-planor wave guide in hfss but I don't have any ideas about this .(This wave guide connected the micro-strip antenna it is used for feeding ).Thanks
Hi, I am looking to configure a computer that can run hfss projects with meshs greater than 250,000. Currently, I have a Pentium Dual Core with 3 Gigs of Ram and 160 Gigs of free HD space. However, once my mesh goes over 250,000 the simulation stops and tells me not enough I think my best bet is to get a 64-bit processor and 8
I'm afraid you can't because hfss cannot simulate active components
hi guys, I'm doin this project based on the article A.Sevinc and Levent Sevgi " Millimetre Waveband Semisymmetrical Groove guide Resonator" IEEE microwave magazine 2004. At the moment i'm tryin to simulate it using Ansoft hfss but i couldn't seem to find a way to excite the dominant TE10 mode in the groove region. The resonator should be coupled t
Hello, can you help with design of this antenna. Which solution I must use - modal or terminal? I see that in hfss 10 guide there was a terminal solution! Why it gives to me s11= 0 db? I calculate with big accuracy and big box. Must I do the coaxial with 3 tubes how in hfss 10 guide or can I do how in file (...)
question on the example:Ultra-High Frequency (UHF) Probe;(from hfss example pp5.1-1 Ansoft High Frequency Structure Simulator v10 User?s guide) one is the simulation time is very long,much long than the microstip filter; and the other is information: Warning - Boundary 'Rad1', Boundary 'gnd_plane' : Boundaries overlap.
