Hi Everyone,

I have designed a horn antenna for Bluetooth application and for simulation purpose I just want to make one with curved end. I have tried to do it by intersecting with circle, but the problem is when I changed the length of the horn antenna the shape of the curve is changed too and becomes flat.
In case it may help to clarify my idea, I have attached two pictures before and after.

So would you please give me a hand, if there is any other way to design the curved part of the horn.

Thank you for your time
 

Hi Mill2ooo,

Are you specifying the number of segments per circle? If not, you may run into issue with the circle rendering improperly. This has caused me many issues in the past...
 

Hi PlanarMetamaterials,

Thank you for your reply.
No, I didn't specify.
