Antenna phase control method and device

An antenna phase control device and an antenna disposed on a moving carrier, and the antenna phase control device comprising:

• a positioning unit configured to obtain a location information of the moving carrier;
• a navigation unit electrically connected to the positioning unit and configured to obtain a destination information of the moving carrier and generating a navigation information according to the location information and the destination information;
• wherein the navigation information comprises a path from the location information of the moving carrier to the destination information;
• a calculation unit electrically connected to the navigation unit and configured to calculate at least one preset location point in the path and a phase information of the antenna corresponding to the at least one preset location point;
• and
• a control unit electrically connected to the positioning unit, the calculation unit and the antenna, and the control unit configured to obtain the location information, the phase information and the at least one preset location point and configured to control a phase of the antenna according to the phase information of the antenna corresponding to the at least one preset location point when the moving carrier reaches the at least one preset location point;
• wherein the calculation unit is further configured to extract a first location point and a second location point in the path and obtain a first direction information of the first location point, a second direction information of the second location point, a first slope information of the first location point and a second slope information of the second location point,
• the calculation unit is further configured to apply the first location point or the second location point as a preset location if a first variation amount of the first slope information of the first location point compared with the second slope information of the second location point is greater than a first threshold value or a second variation amount of the first slope information of the first location point compared with the second slope information of the second location point is greater than a second threshold value, wherein the first location point is adjacent to the second location point in the path.
