  The notion of retro Banach frame with the help of b-linear functional in
n-Banach spaces is being presented. Some properties related to the construction
of new retro Banach frame in n-Banach space have been studied. In n-Banach
spaces, some perturbation results of retro Banach frame have been discussed.
Finally, we give a condition in which finite sum of retro Banach frames is a
retro Banach frame in n-Banach space.
