Abstract

According to one embodiment, a planar antenna device includes a support portion, a first plate-shaped movable portion, a second plate-shaped movable portion, a third plate-shaped movable portion, and a pair of plate-shaped antenna units. The support portion is formed to have a plate shape. The first plate-shaped movable portion is supported by the support portion and is rotatable around a first axial line. The second plate-shaped movable portion is supported by the first plate-shaped movable portion and is rotatable around a second axial line. The third plate-shaped movable portion is supported by the second plate-shaped movable portion and is rotatable around a third axial line. The pair of plate-shaped antenna units is turnably supported by the third plate-shaped movable portion and is switchable between a closed state and an open state.

Claims7

Dependent claims

A planar antenna device comprising:

a support portion that is formed to have a plate shape;
a first plate-shaped movable portion that is supported by the support portion and is rotatable around a first axial line extending in a thickness direction of the support portion;
a second plate-shaped movable portion that is supported by the first plate-shaped movable portion and is rotatable around a second axial line extending along a main surface of the support portion;
a third plate-shaped movable portion that is supported by the second plate-shaped movable portion and is rotatable around a third axial line extending in a thickness direction of the second plate-shaped movable portion;
and
a pair of plate-shaped antenna units that is turnably supported by the third plate-shaped movable portion and is switchable between a closed state in which main surfaces of the antenna units are disposed so as to face each other and an open state in which the main surfaces are disposed on the same plane as each other.
