A multi-band antenna using internal/external air-cap technology is provided to reduce the total thickness of an antenna by attaching an adhesive material and emitters on an upper part of an antenna's cap. A master dielectric(200) is formed by a main connection pin(205). A supporting plate(207) represents a substrate which supports an antenna. A ground air-layer complementary material(209) is formed on the supporting plate in constant thickness. A main ground surface(202) is formed on the ground air-layer complementary material in constant thickness. A main emitter(201) is formed on the main ground surface in order to emit and absorb electromagnetic wave. An emission air-layer complementary material(210) surrounds the main emitter in constant thickness.
