<p>A multi-resonant broad band antenna is provided to obtain a wide resonant frequency band and miniaturization. A multi-resonant broad band antenna comprises a dielectric substrate(51), a first radiation element(53), a dielectric layer, a second radiation element(55), and a feeding unit(52). The first radiation element of a fractal shape is formed on an upper plane of the dielectric substrate. A first lattice pattern of the same shape is formed repeatedly. The dielectric layer is arranged on an upper plane of the first radiation. The second radiation element of a fractal shape is formed on an upper plane of the dielectric layer. A second lattice pattern of the same shape is formed repeatedly. The feeding unit feeds a power to the first radiation element. The first radiation element is a parasitic radiation element which is not connected to the feeding unit.</p> |
