HI：
How could I know the dimension of the microstrip-disk to compensate the inductance of the probe for microstrip antenna with electrically thick substrate?
Can somebody recommend some formulars or papers?
Thank you for your time.
Re: Can HFSS simulate multi-ports with simultaneous excitati
The type I studied is a two-element aperture-coupled microstrip antenna, two lumped ports have been set to the corresponding feeding microstrip lines. Could you tell me how to set the port conditions correctly? Thank you again.
Hi, I am simulating a two-elment microstrip antenna array using HFSS 9.0. During the simulation I have set two ports,but the status bar indicates that the two ports can not be excited simultaneously and the processing is terminated. Who can tell me how to solve this problem without modeling the...
Re: S-parameter in HFSS
Hi
From the help of HFSS, if you use a "current source",the S parameter can't be obtained. If you use a "lumped port",the power transfer in to the port is 1mw(I am not sure).Then using the charactistic impedance of the port ,you can obtain the current.
The energy is coupled to the microstrip patch througth the slot in the groud plane. A substrate and a microstirp thansmission line is below the groud.
How to establish the model and is there any good papers about that kind of antenna?
How to keep the radiation of the microstrip line from the...
Well, conceptly it can be done by near field and far field transformation.
You can see the materials form any classic FDTD books. As for E plane and H plane, you only need to define an angle of radiation pattern you want to caculate such as fai=0 and fai=90
