Abstract
Disclosed herein is an antenna system including a radiating component for transmitting and/or receiving a radio frequency signal, the radiating component longitudinally aligned along a first axis, and a reflector assembly coupled to the radiating component through a gimbal, wherein the gimbal is configured to rotate the reflector assembly about the first axis to steer the antenna system, such that when the reflector assembly is rotated, the location of a focal point of the reflector in space remains unchanged.
Claims21
An antenna system, the system comprising:
- a radiating component for transmitting and/or receiving a radio frequency signal, the radiating component longitudinally aligned along a first axis;
- and
- a reflector assembly coupled to the radiating component through a gimbal;
- wherein the gimbal is configured to rotate the reflector assembly about the first axis to steer the antenna system, such that when the reflector assembly is rotated, a focal point of the reflector in space remains unchanged.
A method of steering an antenna system, the method comprising:
- actuating a gimbal coupling a reflector assembly of the antenna system to a radiating component of the antenna system about an axis aligned with a longitudinal axis of the radiating component;
- wherein when the gimbal is actuated, the location of a focal point of the reflector in space remains unchanged.
(canceled)
A method of transmitting or receiving RF signals, the method comprising:
- reflecting a first RF signal with an antenna reflector to or from a radiating component while the antenna reflector is in a first position;
- steering the antenna reflector from a focal point of the reflector from the first position to a second position, such the focal point remains fixed in space as the antenna reflector is steered;
- and
- reflecting a second RF signal with the antenna reflector to or from the radiating component while the antenna reflector is in the second position.
An antenna system comprising:
- a radiating component for transmitting or receiving an RF signal;
- a reflector for reflecting the RF signal to or from the radiating component, the reflector having a focal point;
- and
- a gimbal configured to steer the reflector from the focal point of the reflector such that the focal point remains fixed in space as the reflector is steered.
