PROBLEM TO BE SOLVED: To provide a three-dimensional antenna that is built in the inside of an information terminal apparatus or the like such as a personal computer or a PDA, is excellent in communication sensitivity in a wireless LAN band in addition to a WiMax band, and has achieved both miniaturization and strength of the antenna.SOLUTION: A three-dimensional antenna has adopted a structure in which a dielectric substrate and a dielectric cover hold an antenna element and part of a ground plate between them. Part of a radiation element included in the antenna element is held by and between the dielectric substrate and the dielectric cover on a plane different from a plane formed by another radiation element. |
