1. A wireless communication device comprising:
an antenna having an element rod-shaped;
a support portion supporting the antenna rotatably about a rotation axis orthogonal to an extending direction of the element;
an actuator configured to rotate the antenna about the rotation axis;
a floating body supporting the support portion and capable of floating on water;
a sensor configured to measure a physical quantity related to inclination of the support portion; and
a control device, wherein
the control device comprising one or more processors configured to perform as:
a measurement value acquisition unit configured to acquire a measurement value of the sensor; and
a rotation control unit configured to drive the actuator according to the measurement value to match a direction in which a change in the inclination is smallest with the extending direction of the antenna.
