hi evrybody!
what shud i do to remove the following WARNING. which shows like this:
"S-Parameter simulation
WARNING: S-parameter result show unphysical behaviour for certain frequencies.
CAUSE:
1. inaccurate (high frequency) calibration
2. higher order modes at the ports.
3. slot mode at coplaner ports
4. grouped strip-slot ports
5. too coarse of mesh "
thanx!

This comes when the circuit is complex and has no reference gnd plane.
how shud i make the "ref. gnd plane"?
Place a port on a layer you feel that should be your reference GND plane.
Mom--> port editor---> port type--->GND reference
