Abstract
An antenna apparatus includes a tabular ground conductor, a radiation conductor facing the ground conductor, a short-circuit portion for short-circuiting the ground conductor and the radiation conductor, an opening disposed on the ground conductor where the location is positioned at a distance of d from the short-circuit portion in the in-plane direction of the tabular ground conductor, and a feed portion extending from the radiation conductor and passing through the opening in a noncontact manner regarding the ground conductor. The feed portion is connected to a matching circuit. The distance d between the short-circuit portion and the feed portion is the length such that the antenna is not resonant at a frequency used for communication, and the matching circuit performs adjustments such that the antenna is constrained to resonate in one or more communication frequency bands.
