calculate characteristic impedance

how can i calculate characteristic impedance and electrical length.

when following things are given

impedance values of the integrated circuit and the antenna at system frequencies

Hi,

Are you asking for the calculations for an impedance transformer between the IC and the antenna?

Natnoraa

yes. i am asking about that transformer moreover that transformer has no effect in my structure can you explain the coupling technique

which output variables am i supposed to store to get resonance at two frequencies that's the main concern

Hi,

Sorry but i do not seem to understand what you're trying to ask or drive at
