ABSTRACT:
Methods and apparatus provide vibration-free steered-beam antennas using a module to accommodate segregated de and rf signals. A phase-shifter element is disposed within an interior of the module. A radiating element is provided, and an rf interface is adapted to couple energy between the phase-shifter element and the radiating element. The rf interface is disposed entirely within the interior of the module and is adapted to provide an rf interface with the module substantially only through the radiating element. A dc interface is adapted to couple energy between the phase-shifter element and an electrical connection element disposed exterior to the module.
