ROTATABLE ANTENNA SYSTEM WITH WIRELESS ROTATABLE INTERCONNECT

Abstract:

A rotatable antenna can include a wireless rotatable interconnect having a stator coil pad coupled to a power supply port for receiving power and to a data port for communication of data and a rotor coil pad that is in bi-directional communication with the stator coil pad. The rotor coil pad superposes the stator coil pad and the rotor coil pad is spaced apart from the rotor coil pad, and the rotor coil pad is rotatable about an axis. A radiating element is coupled to the rotor coil pad, and changes in a rotation of the rotor coil pad about the axis to change a pointing direction of the radiating element. A plurality of wireless channels are established between the stator coil pad and the rotor coil pad and a first channel of the plurality of wireless channels transfers power from the stator coil pad to the rotor coil pad.
