    microstrip filter simulation in hfss

    one more thing, to make the vias, I first put a cylinder in my structure, with height of dielectric layer plus copper, and then subtract these two from the cylinder. and put a copper cylinder instead. is that right? thanks.

    microstrip filter simulation in hfss

    Do u know how I could estimate the working frequency?

    microstrip filter simulation in hfss

    Hi, I need to simulate the attached structure in HFSS software. could any one tell me what the whole structure is? is it a filter? i can only recognize the comb-line filter at the right. if it is, what is the frequency? and to simulate the vias, I made a hole and put a copper cylinder to...

    port inhomogeniously filled error

    I am not sure, but have you tried increasing mesh cells or mesh line limit ratio!

    doing small projects together

    I don't know what IE3D is, I thought it would be good to simulate it in CST and HFSS. - - - Updated - - - I just joined the group, O.K. Rest of the work will be continued in:

    doing small projects together

    Thank you. let's simulate this antenna. and compare our results. we can ask each other our problems here!

    doing small projects together

    our next project, if any one is interested, could be an aperture antenna as can be seen in the picture, we can simulate in in CST and HFSS.

    inserting s parameters to ADS

    One more question, I want to use this transistor to design a low noise amplifier. How can I import the noise information?

    inserting s parameters to ADS

    I haven't found anything. I don't know how to look for it!

    inserting s parameters to ADS

    Right now I am looking for a transistor FHX76LP. It's a FET I guess!

    inserting s parameters to ADS

    Thanks a million RealAEL, I finally could find the transistors in ADS :grin: But I'm still not able to insert a model from a site into ADS, could you please help me with that? I am really sorry.

    inserting s parameters to ADS

    Hi, I want to find a transistor and insert it to ADS, But I don't know how. Could anyone please help me! The transistor I am looking for right now is: sp_hp_AT-41435_1_19921201. I don't even know how to look in ADS library for a transistor. Any help would be totally appreciated.
