I have desighned a PIFA antenna as shown bellow..

But the problem is that i get my radiation pattern changed as a function of my Ground Size.

I know that if the ground plane is large enough then the radition pattern is stable, but in reality its not.

So one essumption i found is ground currents . We need to cancel these ground currents with "CHOKE"

Choke is basickly an inductor, in high frequency its a open circuit.

here i have a PIFA anttena ,how can i mplement this principle here? Is there some article i could read which could help me solve this problem? Thanks
