[SOLVED] circle slot in the middle of rectangular patch antenna (ads)

Hi,
How to create a hollow circle slot in the middle of rectangular patch antenna using ads

Re: ADS hollow slot

Use Momentum and define an "x" layered board with the depth graeter than
this hollow hole.

This is not trivial to do right, so you might want to read all the help files, they
call ADS's tech support. Good luck

2. Draw the circle on the same layer as the rectangle at the required size and in the correct position.
3. Select both the rectangle and the circle.
4. From the menus run the command Edit > Merge > Union Minus Intersection.
5. Done.
