Abstract
An antenna device includes; a metal housing in which at least one surface thereof is open; a display unit provided inside the metal housing and configured to perform a display from the one surface of the metal housing toward outside; a first transparent conductor plate present in the display unit; a second transparent conductor plate provided to be spaced apart from the first transparent conductor plate in an outside or inside direction, the second transparent conductor plate to define a gap between the second transparent conductor plate and the metal housing; and a feed unit provided between the metal housing and the second transparent conductor plate.
Claims13
An antenna device comprising:
- a metal housing in which at least one surface thereof is open;
- a display circuit provided inside the metal housing and configured to perform a display from the one surface of the metal housing toward outside;
- a first transparent conductor plate present in the display circuit, the first transparent conductor plate to define a first gap between the first transparent conductor plate and the metal housing;
- a second transparent conductor plate provided to be spaced apart from the first transparent conductor plate in an outside or inside direction, the second transparent conductor plate to define a second gap between the second transparent conductor plate and the metal housing;
- and
- a feeder provided between the metal housing and the second transparent conductor plate,
- wherein when a length of the first gap is different from a length of the second gap, a ratio of an area of the second transparent conductor plate with respect to an area of the first transparent conductor plate is 0.6 or more and 1.1 or less.
