Could you please help me to design a pyramidal horn antenna and obtain his radiation pattern with HFSS?
Thanks

Not sure about HFSS, but how about in FEKO? The model can be downloaded if you're a user.

What do u mean? I guess u need how to know how to draw it and simulate it, don't you? The easiest way to do it is to create the pyramidal structure by using polylines. I designed some horns in the past. If u are interested on it I can upload a sample file.
Should you need equations to design ur horn u can find them in 'Antenna Theory' book by C. Balanis (I seem it is chapter 11, but I'm not sure). Let me know if this is enough or u need the sample file.

i want to design it in the range of 1Ghz to 3Ghz, here are parameters with 15dB gain and cutoff frequency of 0.95Ghz,
a = 15.789cm (one dimension of waveguide)
b = 7.8945cm (2nd dimension of waveguide)
a1 = 39cm (dimension of horn surface)
b1 = 28.371cm (dimension of horn surface)
length of horn surface = 16.44cm
length of waveguide = 8.494cm
i calculate all these with the help of design procedure given in Balanis's book, and calculation of waveguide from David A.Pozar. i will wait for your reply, i need any modal of wide band horn antenna in HFSS working over any range. so that i may get help regarding design.
i am attaching a file kindly check it too. although it seems very good, but problem with it is, that it does not start from zero , kindly comment over it too.

Sorry, but you need login in to view this attachment

Hi Kamran, could you please post your email address. I'm also trying to design a horn antenna. I could use you guidance on the matter.

Kind regards,
Don

Hi Kamran,
The Broadband antenna you want to design is not simple horn.
You need to add ridges in the waveguide & horn section to increase your bandwidth.

Search for Double or quadridged horn design in search engines.

You will get many papers or references.

If you stuck at any point then you can send me personal messege.
