Claim Text:
1. An antenna device comprising: a planar base; a first planar conductor disposed in the planar base; a second planar conductor disposed in the planar base, such that the second planar conductor is adjacent to the first planar conductor in a plan view of the planar base; and a coil antenna that includes a coil conductor wound along a winding axis and a magnetic body disposed at least inside a winding region of the coil conductor, wherein the coil antenna includes first and second coil openings in the winding axis of the coil conductor that are disposed adjacent to respective edge portions of the first and second planar conductors, respectively, wherein each of the first and second planar conductors includes a portion that does not overlap with the winding region of the coil conductor in a direction normal to the planar base, wherein the winding axis of the coil conductor extends in a direction parallel to planar surfaces of the first and second planar conductors, and wherein at least one of the first and second planar conductors is insulated from direct contact with the coil conductor.
