Hi,
I am trying to design an interdigital bandpass filter with round rods and tried two synthesis sofwares
1- An excel software in rfshop.com
2- intfil.exe
both of them are free on the internet
However, when i used the results of these sofwares in CST, the simulation results are very very bad. Is there a limit for the frequency range of these synthesis tools (can I design at 50GHz) or how shall i synthesize at high frequencies ? How can input coax model and tap point be modeled in CST? Also is there limitations for rod diameter, ground plane spacing and first rod to wall spacing ?
Can anyone suggest me any free synthesis software for this kind of filter and CST examples?
Thank you...
