STACKED TYPE MULTI BAND ANTENNA DEVICE

摘要

PURPOSE: A stacked multiband antenna apparatus is provided to easily implement multi band characteristics by arranging a number of radiation patches with a fractal structure on a plane arrangement radiation element. CONSTITUTION: A plane arrangement radiation element(102a,102b) faces a feeding element(101). The radiation element includes a pair of dielectric substrates(121), radiation patches(123) and a conductor(125). A pair of dielectric substrates is laminated to face each other. The radiation patches is arranged on one side of each dielectric substrate. The conductor is arranged on the other side of the dielectric substrate.
