The antenna module can be rotated into a predetermined orientation, independent of handset orientation.

This second rotation places the antenna at an angle that compensates for tilting of the handset during use about an axis parallel to the second axis, or along the first.

Abstract: A method and a device are disclosed relating to the stabilization of mechanical bodies. The method is based on supporting the body to be stabilized at its mass center, whereby no acceleration in any direction causes a torque induced by the inertial forces in the body.

Inching of the body from the desired position is compensated by a slow control system using actuators functioning on a contact-free principle. As a particularly advantageous embodiment, the invention can be applied for stabilizing bodies attached to moving objects.
