Hi everyone

i have made simulation on HFSS for a patch antenna (with 9.5GHz) but everytime i try to validate it, it keeps saying "substrate and stripline intersect", im not really sure how there are intersecting....so can someone please help me :cry:
 

Patch Antenna help

Your feeding microstrip line is embeded in the substrate.

Just move the feeding MS line a littler upward the z-axis, problems will be sloved.
