I added more pics and cst(2018) file of my design in the link below.
(Moderator action: removed link to external server. Faild to load pictures, anyway)
Results are taken from 10 mesh calculation.
Thank you.

in double-ridged waveguides there is a method which called "cavity back". That cone ending is coming from there. I also tried flat end but it's not working.
Sorry for second reply but I really need help.
For a more detailed view I want to add some screenshots;
By the way i had to decrease cells because my computer is not so good and I had to speed up the calculation but I don't think this makes results this much bad.
S11 when I used ideal...
First i want to specify I wrote wrong the part of "They are below -10 dB" it must be "They are above -10dB".
i tried many of ways to solve this problem but i couldn't. I changed the position of the feed, height of the pin, changing radius of the pin, teflon and outer cover(copper), changing...
Hello,
i'm designing a double-ridged horn antenna in CST. First, i designed it with an ideal waveguide port(i chose back surface of the waveguide and add waveguide port) and i took very good s11 and farfield radiation results in my working band(<-20 dB from 1 to 18 GHz and good directivity in...
Hi,
Let's say we're creating a project in CST and we choose E-field, H-field, and Farfield for results(They are at bottom of the screen). But then, I realize I don't need E-field and H-field results(so, 2d/3d ersults part) (also they're extending simulation time - as I know- ).
So, How can I...
Hello,
I have a frequency reconfigurable microstrip antenna project(2 to 6 GHz Multiband). There are two pin diodes in design(They change the length and provide reconfigurability according to their ON and OFF states). I drawed antenna in HFSS(i'm new to it) but as you know it's a passive...
