simulation of monopole antenna in ansoft designer?

hi
i want to simulate a monopole antenna in ansoft designer
but i have a problem
how to simulate a finite ground in ansoft designer?
the excitation is edge port, and the warning occure is : the S arameter greater than 1!

thanks

post your design pls.

draw monopole and ground in two different layers.

Hi All,
PLEASE HOW CAN I DRAW A MONOPOLE IN ANSOFT DESIGNER?......THE RESULT I PRESENTLY GET DO NOT SEEM TO MAKE SENSE!

Finite ground can be drawn by declaring the layer as "signal" not "metalized signal"
