Patent Images
1. A portable telephone unit, comprising:
- a portable telephone handset;
an antenna module pivotally secured to the handset with a pivot joint for rotation relative to the handset about a predefined pivot axis;
magnetic driving means for urging the antenna module to rotate relative to the handset into a predetermined vertical orientation independent of handset orientation, said magnetic driving means being responsive to gravitational forces to select said vertical orientation; and
an antenna projecting along a direction from the module oriented vertically when said module is in said predetermined orientation.

Abstract
A wireless portable phone handset for use in satellite communication systems having a vertically correcting antenna module pivotally secured to the handset for free rotation about a pivot axis. The antenna module contains a magnetic actuator mechanism for urging the module to pivot into a predetermined vertical orientation regardless of the handset orientation. An antenna projects from the module in a direction which is vertically upright when the module is in its predetermined vertical orientation. As the handset is moved into an angular orientation, the module pivots under influence of gravity, and a magnetic field from a magnetic driver, until the antenna is oriented vertically.
