Monopole antennna design

Can anybody tell me how to design a monopole antenna with coaxial feed in HFSS

1) Make a ground plane with a small hole in the center.
2) Place your monopole perpendicular to the ground plane, starting in the center of the hole (the g-plane and the ant don't touch).
3) Place an air circle, the diameter of the small hole, at the top edge of the ground plane.
4) Place another air circle, the diameter of the monopole and in the same plane as #3 at the center of #3.
5) Subtract the small air circle from the bigger air circle to create a flat donut.
6) Place your energizing vector across one side of your new flat donut.
7) Simulate.

It helped me Thank u:) but we shd draw a cylinder na for coax feed ? can u tell me about the calculation for radius and the length of coax and about how to give excitation.

,,this works too..

I am not getting the design only can u help me how to design in HFSS i am confused abt hw to connect coax to wire monopole and how to assign port



SLK001 can u plz tell me how to assign a port for that antenna

If this helped you, click on this in the helping post.

You don't need to draw/create a coaxial line for the feed. For the rest of your questions, please consult the HFSS manual.
