1. An antenna element comprising:
- a feeding part; and
a mesh part including at least a part of an area formed in a mesh state, whereinthe feeding part and an area of the antenna element in close proximity to the mesh part are formed of a finer mesh than the mesh part or formed of a solid,a portion of the antenna element is configured to be bent, and the bent portion is formed of a finer mesh than the mesh part or formed of a solid,a relationship between a line width W and a line interval D of the mesh part substantially satisfies D≧
22W, andthe line width W is equal to or greater than double a skin depth of a conductive material of the mesh part with respect to a target frequency of the antenna element.
