Captain America: the First Avenger and Avengers: Age of Ultron already featured minor Easter Eggs for the Black Panther with the inclusion of Vibranium. The "world's strongest metal", Vibarnium is the material used to create both Captain America's shield and the Vision's body. Long-time readers of the comics will know that Vibranium is the main export of Wakanda, the fictional African country ruled over by T'Challa. Largely kept a secret to the outside world, Wakanda became one of the most technologically advanced countries by selling off minute quantities of the metal to foreign buyers. As Ant-Man seems likely to be more localised than the galaxy-spanning adventures in the Thor films, or even the world-trotting Avengers, it's unlikely that Black Panther will play any major role in the film. However, with Black Panther scheduled to appear in the upcoming Civil War, and a Black Panther movie set for 2018, it's likely that the character or his country of origin will get a look in of some sort in the film.
