PROBLEM TO BE SOLVED: To provide a compact and light-weight antenna supporting mechanism capable of transmission/reception to and from artificial satellites existing in a wide range in a mobile object tracking device for artificial satellite communication. SOLUTION: Antennas 1, 11 are supported by an oscillation mechanism having the degree of freedom of rotation on an X-Y plane from a fixed supporting part, oscillation center axes 101, 105 are allowed to intersect with each other on the same plane and a driving mechanism such as a driving motor is arranged on the oscillation center axes, so that the antenna mechanism can control the elevation angles and azimuth angles of the antennas 1, 11. Thereby the device weight and height of the antenna mechanism can be reduced and there is an effect for reducing the size and weight of the mechanism. |
