Abstract
An antenna element including a feeding part and a mesh part including at least a part of an area formed in a mesh state. The 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.
Claims11
An antenna element comprising:
- a feeding part;
- and
- a mesh part including at least a part of an area formed in a mesh state, wherein
- the 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, and
- the 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.

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