Abstract
An antenna device according to the present disclosure includes: a metal housing which includes an opening part on one surface, and in which a liquid crystal display including a transparent conductive film facing the opening part is disposed; an antenna conductor that includes an end surface forming a gap being a slot line between the end surface and an edge surrounding the opening part of the metal housing, constitutes a composite right handed/left handed transmission line on at least part of the slot line, causes the composite right handed/left handed transmission line on the slot line to function as a leaky wave antenna, and allows visible light to transmit through the antenna conductor; and a power feeding point disposed in the gap.
Claims9
An antenna device comprising:
- a metal housing which includes an opening part on one surface, and in which a liquid crystal display including a transparent conductive film facing the opening part is disposed;
- an antenna conductor that includes an end surface forming a gap being a slot line between the end surface and an edge surrounding the opening part of the metal housing, constitutes a composite right handed/left handed transmission line on at least part of the slot line, causes the composite right handed/left handed transmission line on the slot line to function as a leaky wave antenna, and allows visible light to transmit through the antenna conductor;
- and
- a power feeding point disposed in the gap, wherein
- the antenna conductor includes a slit group including a plurality of slits which have end surfaces opened in contact with the slot line, and are arranged in parallel,
- the plurality of slits, and a plurality of inductors electrically connected between one side surface sides of the respective plurality of slits and the metal housing constitute a left handed transmission line in the composite right handed/left handed transmission line, and
- a right handed transmission line of the composite right handed/left handed transmission line is present in the slot line in a region of the antenna conductor in which the slit group is formed.
An antenna device comprising:
- a metal housing which includes an opening part on one surface, and in which a liquid crystal display including a transparent conductive film facing the opening part is disposed;
- an antenna conductor of which an end surface is disposed in such a way as to have a gap between the end surface and an edge surrounding the opening part of the metal housing, and which includes a plurality of slits having end surfaces in contact with the gap and arranged in parallel, and allows visible light to transmit through the antenna conductor;
- a plurality of inductors electrically connected between one side surface sides of the respective plurality of slits of the antenna conductor and the metal housing;
- and
- a power feeding point disposed in the gap.
