[Istvan Novak <istvan.novak@xxxxxxx>]

Boopathy,

Not knowing the RF system parameters you have 
to achieve, just based on the stated frequency, 
you probably want to create a tuned loop antenna.  
In this case the trace impedance matters less, 
in fact you may want to increase it as much 
as possible. More will matter the size 
(and orientation) of loop and the number of turns.
