Abstract
An antenna element includes a first opening including an annular outer boundary in an antenna conductor layer. A first insulative substrate non-forming region is provided between an insulative substrate and the antenna conductor layer in an up-down direction. The insulative substrate does not exist in the first insulative substrate non-forming region. The outer boundary of the first opening overlaps one or more first insulative substrate non-forming regions and is not in contact with the insulative substrate. The first insulative substrate non-forming region is a first void, and a low dielectric constant material having a lower dielectric constant than that of a material of the insulative substrate or a high dielectric constant material having a higher dielectric constant than that of the material of the insulative substrate is provided in the first insulative substrate non-forming region.
