1. An antenna device comprising:
- a plate-like antenna element having an electrically conductive path arranged in a two-dimensional manner;
a feed line connected to the antenna element; and
a support, while causing the antenna element to be spaced away from an electrically conductive material layer of an outer shell of a movable body, holding the plate-like antenna element in such a manner as to conform to a front surface or a back surface of the outer shell,the plate-like antenna element comprising;
(i) a first root section being a part of the antenna element which part extends from one end part of the electrically conductive path by a predetermined length;
(ii) a second root section being a part of the antenna element which part extends from the other end part of the electrically conductive path by a predetermined length; and
(iii) an intermediate section which is a junction between the first root section and the second root section,the first and second root sections having first and second feed sections respectively provided therein, the first and second feed sections being each connected to the feed line,the intermediate section having the electrically conductive path provided therein, the electrically conductive path having a meander shape with a return pattern, andthe support being made from a dielectric material.

Abstract
An antenna device includes: a plate-like antenna having an electrically conductive path arranged in a two-dimensional manner, the electrically conductive path having a meander shape which is made up of at least one return pattern; and a base member, while causing the antenna to be spaced away from an outer surface of a body containing an electrically conductive material layer of a movable body, holding the antenna in such a manner as to conform to the outer surface, the base member being made from a dielectric material.
