Provided is an antenna structure that can be attached with ease and is likely to blend into environments. An antenna structureincludes: plural antenna elementsconfigured individually and arranged discretely; and a basewhich adheres to at least side surfaces of the antenna elements, in which the plural antenna elementsare embedded and fixed, and which forms a plate-like outer shape.

Antenna structure

An antenna structure as an example of a structure including a transparent conductor includes: an antenna as an example of the transparent conductor; a film transmitting a visible light; a positioning structure configured to position the film from an invisible side of a ceiling as an example of a facility; and a flange transmitting the visible light and configured to position the film from a visible side of the ceiling and including a lens part at a position facing the positioning structure.

Structure, antenna structure, and radio wave shielding structure including transparent conductor

The antenna structure as an example of a structure including a mesh-like transparent conductor includes: a film made of an electrical insulating material transmitting visible light; a surface section provided on one face of the film, made of a mesh-like conductive material, and having a predetermined shape; and a bordering section provided on the one face of the film and configured to border at least a part of edges of the surface section &#x3b1; with a conductive material.

Structure, antenna structure, radio wave shielding structure, and touch panel including mesh-like transparent conductor

An antenna structure to which the present invention is applied includes: a film that transmits visible light and has antennas formed thereon; a feeding part to which coaxial cables for feeding power to the antennas are connected; a flange that transmits visible light and is used for positioning the film from a visible side of equipment; and positioning structures for positioning the film from an invisible side of the equipment.

A film antennato which the present invention is applied includes: an antenna partin which a dual-frequency antennaand an antenna GND sectionare formed; a feeding boardto which a coaxial cablefor feeding the antenna partis connected; and a pressing memberwhich, together with the feeding board, sandwiches a contact point, coated with silver paste, of the antenna part, and electrically connects the contact pointand the feeding boardto one another.
