In this paper, we introduce the k-Hankel-Wigner transform on $mathbb{R}$ in some problems of time-frequency analysis. As a first point, we present some harmonic analysis results such as Plancherel's, Parseval's and an inversion formulas for this transform. Next, we prove a Heisenberg's uncertainty principle and a Calder'on's reproducing formula for this transform. We conclude this paper by studying an extremal function for this transform.
