Newbie level 5
Hi guys,
I am working on a h plane horn antenna.
First I calculate all dimensions that it needs, then I simulate it in the CST but my results are strange.
I have a good gain about 6 dB that it is fine in this level
I do not have any loss when I am checking the E-Fields
But my s11 is awful, it is almost zero, working like a resonator.
Do you have any idea why it is like that ?
I am suspicious to feeding and boundaries, because usually these two make your s11 so bad, I used a wave guide port for feeding and I choose open add space as boundaries.
Does anybody have any idea?
I attached the picture of my antenna.
Thanks
