Hi everyone,
I got a question about my coaxial feed loop antenna design in HFSS. My setup is as listed:
1 Wave port excitation, 50ohm normalization with integral line
2.one end of loop is connected to the center pin while the other end to the outer jacket of cable
3. The S11 is weird, and the...
Thank you BigBoss.
I don't know if I got it right. So you are saying if I want to know the transmission-line input resistance. I should used two ports at two ends. And only use Smith Chart to calculate input impedance?
And: one port + radiation boundary is wrong?
and there is no direct way to...
Hi,
So the images above are the result with one waveport + radiation boundary (the sheet at the far side is a non-model object)
And then I used two waveports scheme by assigning the sheet as waveport2 and also set all other surface as radiation boundary. The result I got is shown below, it...
Thank you!
The pictures of the first scheme is uploaded for clarity. I suppose the radiation boundary make small amount of reflection at boundary so it should be neither open and close end. Or the setup is not right?
Hi,
I am a starter in HFSS simulation and I am tring to use HFSS to check my CPW design is 50ohm upto 50GHz.
I used waveport (the size follows the guideline in manual, and normalized to 50Ohm) at one side, and set the radiation boundary to all outer surfaces. The simulated Z11 is fairly close...
