Abstract: A light-transmissive antenna includes: a transparent base made of a transparent insulating material; and an antenna pattern formed on the transparent base. The antenna pattern is made of a transparent electrically conductive film that is a film-like member having a predetermined transmittance and a predetermined electrical conductivity. The light-transmissive antenna includes a plurality of highly electrically conductive patterns arranged on the antenna pattern, each of the highly electrically conductive patterns being made of an electrically conducive member having a higher electrical conductivity than the transparent electrically conductive film and formed in a linear shape. Each of the plurality of highly electrically conductive patterns has a predetermined width set equal to or smaller than a value assumed as a resolution of human eyes.

Abstract: An antenna device includes a ground part, a patch part disposed parallel to the ground part to oppose the ground part, a short-circuit part electrically connecting the patch part and the ground part, a patch area expansion part and a ground area expansion part. The patch area expansion part is provided on a patch-side opposing surface that is a surface of the patch part opposing the ground part to expand an effective surface area that is an apparent area of the patch-side opposing surface with respect to the ground part. The ground area expansion part is provided in a region opposing the patch area expansion part on a ground-side opposing surface that is a surface of the ground part opposing the patch part to expand an effective surface area of the ground-side opposing surface with respect to the patch part.
