Kite.

A kite is a quadrilateral with all the given qualities. It has two pairs of congruent sides, but its opposite sides are not congruent. Now, with these two characteristic we already know it's a kite, because a rectangle and a rhombus has equal opposite sides, the trapezoid doesn't have two pairs of congruent sides.
Therefore, the quadrilateral described is a kite.
