Antenna device

An antenna device comprising:

• an antenna, which is mounted on a vehicle, to receive a radio wave from a positioning satellite;
• and
• a column, to an upper end of which the antenna is attached;
• and
• a plate to cover a surrounding part of the column, wherein
• a joint column is provided in a shaft rotation direction of a longitudinal direction of the column, and
• an internal wall of the plate is connected to the column via the joint column.

An antenna device comprising:

• an antenna, which is mounted on a vehicle, to receive a radio wave from a positioning satellite;
• and
• a column, to an upper end of which the antenna is attached;
• and
• a plate to cover a surrounding part of the column, wherein
• the vehicle is a carriage for measurement that includes a shooting device to take a picture or a video of a surrounding area of the vehicle and a gyroscope to output angular velocity data that indicates an inclination of the vehicle, which are placed near the antenna in an upper section of the vehicle, and
• the column has a length so that the antenna that is attached to an upper end of the column is placed at a position higher than a height of an upper surface of at least the shooting device or the gyroscope.

A vehicle comprising:

• two antenna devices mounted on a front side;
• and
• one antenna device mounted on a back side, wherein
• each of the antenna devices includes
• an antenna to receive a radio wave from a positioning satellite, a column, to an upper end of which the antenna is attached, and a plate to cover a surrounding part of the column.
