I have drawn a pifa antenna in hfss but i cant figure out how to set waveport and radiation boundry . . . . What we do with feed source and short circuit plate in PIFA . . . I am still newbie in hfss please help me out i have to submit my project in three to four weeks time . . I have attached the antenna design so (...)
For some reason, I am having a heck of a time with this: Its actually a little more complicated than I'll give here, but if you can help me with this, that will be enough. Ok, simplest thing in the world, two cyliindrical conductors running through a dielectric block. Ground planes on the ends of the block - one of the conductors contacts bo
am confused about the role of radiation boundary dimension on the simulation results on a patch antenna. can anyone provide me the way to calculate the dimensions of radiation box for a patch antenna in hfss. its really creating problem for me.
Hi, it is depends in the purpose of the boundry. for an example, if you are looking for radiation pattern of antenna, use the radiation boundry. They are two different boundaries.
boundry overlap may just be warnings since PEC takes precedence over radiation, etc. Mesh is a problem since it is usually not fine enough. See the graphics I posted that show the mesh size and it's effect on edge currents. You may have to manually set the mesh size. The Q is highly dependa
You may try seeding the radiation boundry yourself. There is a problem in their generated radiation info. I have found issues with phase data and lower level off axis x-pol data. The boundry seeding is what I was told to try. I havent had much time to play with it to see if its effective or not. Also if you are trying to (...)
