hi there,

I am simulating dual band antenna with very small ground size (20x13)mm using open region setup, I am exciting lumped port.

I get little higher antenna radiation efficiency which can rich greater than 1 in the higher band (5.6 GHz), could you please help me to find the reason for such error ..!!!

Have you taken into account of the associated parasitics?
Also can you increase the ground size and see if this is happening?
All the very best Praneeth.
