In the discussions which I have read on the hfss forum many people discuss exporting solution data to a grid from the field calculator. However I?m not sure how they define this grid.
Hi, jrk2 !
The easy way is to define your own grid file "mypoint.pts " in a format of three columns: X Y Z (in meters!).

For an antenna problem, such as aperture coupled microstrip patch antenna, we set the source at one edge of the substrate, I think now the reference plane is at this position. If I want

by definition, S11 is the reflection coefficient seen into port 1 when port 2 is matched. if you use wave port in hfss, port 2 is terminated with the characteristic impedance of the corresponding "eigen"-mode of a transmission line having the same cross section as the plane in which port 2 lies in. This is achieved by doing some sort of calibration

In your design, box 25 is faulty. I mirrored box 2 and united all.
I guess your design is symmetric.

PS:you have to zip or rar file you want to upload, otherwise, forum does not accept .hfss files.

You can find the hfss manual on this forum
The largest dimensions in your design are much smaller than the wavelength (2.4m in air ~ 30 cm in water) thus you should not use a high frequency simulator but a low frequency one, hfss might not work. This answers to questions related to ports, rad

I want to stress that hfss stands for High Frequency structure simulator. Therefore 13 MHz would not seem like a high frequency. And yes, a quarter-wavelength distance from the nearest radiating edge is required for the radiation boundary. PML would reduce your simulation time as the distance can reduce down to lamda/6 to lamda/10. In

You can have a waveport defined inside the airbox; you just need to place a solid PEC geometry (say a cube) on the other end of the waveport to let hfss know which direction to solve for. I tried this and got good results.
