Hi all,
i need a formulation for the antenna active input impedance. Starting from the Z matrix (i know it thanks to a simulator), i have to find a formula for V1/I1 when the two ports are simultaneously feeded.
I google it, but i have not find anything useful.

Do you have any idea / link ?

Thank you.

PS: sorry for my english ^^
