Antenna device

An antenna device, comprising:

• an antenna portion;
• a hinge portion formed on the antenna portion;
• a base portion attached to the hinge portion so as to be pivotable thereabout, wherein:
• the hinge portion includes:
• a hinge base having a first shaft formed on one end thereof, a second shaft formed on the other end thereof, and a first protrusion formed on an outer periphery of the second shaft;
• and
• a hinge bush rotatably mounted on the first shaft and engaged with the base potion;
• the base portion is formed with a hole surrounding the outer periphery of the second shaft;
• a projection is formed on an inner periphery of the hole;
• and
• the first protrusion is brought into contact with the projection when the base portion is pivoted so as to define a predetermined angle with respect to the antenna portion.

An antenna device, comprising:

• a ground plate adapted to be electrically grounded;
• an antenna plate;
• an antenna probe feeding to the antenna plate;
• a probe holder which is comprised of resin, interposed between the ground plate and the antenna plate, and holding the antenna probe, wherein:
• an area of the probe holder is equal to or larger than at least one of an area of the ground plate and an area of the antenna plate.

An antenna device, comprising:

• a first cover;
• a second cover coupled to the first cover and defining a space therebetween;
• an antenna module accommodated in the space;
• a signal line electrically connected to the antenna module and led out from the space;
• a packing member interposed between the first cover and the second cover so as to close the space in a waterproofing manner, wherein:
• the packing member includes a frame portion formed with a groove and a bush portion into which the signal line fitted;
• and
• the second cover includes a rib fitted into the groove.
