Abstract
The present invention relates to an antenna using a complex structure in which dielectric substances having a low dielectric constant and magnetic substances having a high magnetic permeability are arranged vertically and periodically in order to improve the gain, efficiency, and bandwidth of the antenna while maintaining a small size which is an advantage of a conventional antenna using dielectric substances having a high dielectric constant. The present invention provides the antenna using a complex structure having a vertical and periodic structure of dielectric substances and magnetic substances, comprising a substrate and a radiation patch formed on the substrate. The substrate includes a plurality of layers. Each of the layers has the dielectric substances and the magnetic substances of a bar shape alternately arranged therein and has the dielectric substances and the magnetic substances alternately laminated thereon even in a height direction.
