Abstract: In this paper, we will presennt a new type of smooth constant breadth curves with the help of the polar tangential coordinates (Minkowski's support function) for the closed convex curves in the plane.

Key words: Minkowski's support function, convex curves in the plane, constant width curve, Minkowski's support function, convex curves in the plane
