The invention discloses a dual-band antenna apparatus comprising a medium substrate, a first antenna unit and a second antenna unit, wherein the first antenna unit and the second antenna unit are arranged on the medium substrate. The first antenna unit comprises a first feed input terminal, a first radiation portion and a first grounding portion, wherein the first radiation portion and the first grounding portion are connected with the first feed input terminal. The second antenna unit comprises a second feed input terminal, a second radiation portion and a second grounding portion, wherein the second radiation portion and the second grounding portion are connected with the second feed input terminal. A Balun comprises a third grounding portion and is arranged between the first antenna unit and the second antenna unit. The second antenna unit is connected with the Balun integratedly through the second grounding portion. The first radiation portion is in a similar-U-shaped metamaterial man-made microstructure
