PROBLEM TO BE SOLVED: To provide an antenna device with reduced deterioration in characteristics caused by surrounding metal bodies, and that is low in cost and size, and to provide a method of manufacturing the same.SOLUTION: An antenna device comprises: a dielectric substrate 21; a ground conductor 101 formed on a surface or an inner layer of the dielectric substrate 21; and at least one antenna conductor 1 formed on the surface or the inner layer of the dielectric substrate 21, and that includes an element of an inverted L-shaped antenna connected with an outer periphery of the ground conductor 101. The dielectric substrate 21 comprises at least one deletion part 31 where the dielectric substrate 21 is penetrated and removed, at least at a part of a region sandwiched between the ground conductor 101 and the antenna conductor 1.SELECTED DRAWING: Figure 1 |
