3D Modeler -> Surface -> Cover Lines is the one, i think. Remember to select all lines closing an area when clicking this command, otherwise it might be grayed out...

one of the arm is suppose to be gnd while one of the arm is the conducting arm right?
from your picture, did you draw the line from the ground to the conducting arm?

i have did it but it cant work
rfmw said:I see a spiral feed as a "differential" port, therefore there is no gnd, as would be normally for i.e. microstrip (that is trace and groundplane). Lumped port does the job very well. The integration line is from one spiral to the other, simple as that. Isn't this obvious from the pictures?
