urgent kindly tell me how to convert closed polyline surface to patch shape in hfss

hi all
i want to draw a coplanar microstrip patch antenna
can u tell how to convert polylines to a closed patch shape
then how this closed polyline will be considered as patch
of a defined height which will radiate
actually physically if we see then a cosed polyline structure without any height
will it radiate
can someone solve my problem
regards
kartik

for patch antenna, download the antenna design toolkit from the ANSYS site. It is free and will create the whole patch model (several different types) for you including parameterization!

Have Fun!
