Hi,
Attached you will find the modified file. Three lowest resonances are 1.224, 1.950 and 1952 GHz. By selecting the dimensions and the location of the input/output probes you can select the mode you want to couple into. I added the second wave guide port to show the resonator response. You...
Let's have a five section filter with an unloaded Q of 1000. Passband 980-1000 MHz. Coupling matrix :
MS,1=0.021862
M1,2=0.01939
M2,3=0.014682
M3,4=0.01939
ML,4=0.021862
External quality faxtor of input and output 42.27
CBW12=19.2 MHz
CB23=14.53 MHz
CB34=19.2 MHz
So how do I derive the loaded...
Hi,
I would need a twisted wire pair in HFSS. Two round insulated wires diam 0.6mm twisted 1 turn per 10 mm and length for example 50 mm. This is like old twisted telephone wire pair. Has anyone drawn something like this?

Hi,
I tried to download the Mathcad routine for Chebyshev filters from circuitsage web page but it seems that the code is corrupted. Does anyone happen to have that routine? link: http://circuitsage.com/filter/cheby.mcd

Hi,
I have transferred many designs from ADS and with no problem. I have only imported the copper as dxf. Substrate, ports etc. have to added of course. Copper thickness in imported file dxf has been 0.1mm (set value) and it needs to be corrected. Have you checked that your substrate is...
Hi Odyseus,
I had a look at your design and made some corrections/changes to model:
1) Resonators coupled still capacitively but from the side, not from the top.
2) Tuning screws added to design.
3) Capacitive coupling between resonators changed to inductive (to lower end).
4) Tuning between...
Hi,
I installed the latest ViaWizard 3.1 and it did not work too. I received information that you have to have Visual Basic in your machine but I do not know what version. Then I installed Visual Basic 2008 but it was the same result - not working. The only one that is working is the old...
Via Wizard 3.0 in HFSS?
Has anyone been working with Via Wizard 3.0 in HFSS? I met a problem after loading the wizard, I cannot generate the project and menu buttons at the top are not active. Has anyone faced the same? My OS is XP home. I also tried it in XP64 and it is claiming of a missing...
Hi,
Has anyone faced this with Ansoft Designer 5.0 beta and HFSS 12: When trying to tune the model (made in HFSS) by using dynamic link, there is no tuning menu available for that HFSS component. Only Value and Statistics are possible to select. This similar thing is working in Ansoft Designer...

Hi,
I just downloaded the FEKO lite version 5.4 (4.0.104014) and when I import a file from AntennaMagus it gives me an error message ...was written by a newer CADFEKO (4.0.117480) and is not compatible with this CADFEKO (4.0.104014).
So where do you get that version, not from...
Hi,
Has anyone succeeded in exporting Yagi-Uda design from AntennaMagus to CST? The very same design export to FEKO is OK but to CST the exported file size is zero. Has anyone faced the same problem?

Hi,
You must connect your LC-circuit with a very small capacitor 10-20 fF from i nput and output ports in order not to load the circuit. You can change the capacitor value to shift the peak level to about -30 dB or so, then the 50 ohm port loading does not load your circuit. You...
Hi,
You can also made the Bandpass filter by using highpass and lowpass filters in cascade. Sometimes it is easier to design wideband LC-type filter with good performance by cascading filters.
