Abstract
Examples disclosed herein relate to a phased array antenna system for use with a Low Earth Orbit (“LEO”) satellite constellation. The phased array antenna system has a plurality of antenna panels positioned in a dome and an antenna controller to control the plurality of antenna panels, the controller directing a first antenna panel to transmit a first signal and a second antenna panel to transmit a second signal to a LEO satellite, the first signal having a first phase and the second signal having a second phase different from the first phase.
Claims12
A phased array antenna system, comprising:
- a plurality of antenna panels each comprising:
- an array of meta-structure cells;
- a feed network;
- and
- an RFIC (radio frequency integrated circuit) coupled to the feed network and adapted to generate a plurality of phase shifts for a plurality of signals, wherein a meta-structure cell from the array of meta-structure cells radiates signals with each phase shift;
- and
- an antenna controller configured to control the plurality of antenna panels by directing a first antenna panel to transmit a first signal to a Low Earth Orbit (“LEO”) satellite and a second antenna panel to transmit a second signal to the LEO satellite.
A satellite ground terminal for use with a satellite, comprising:
- a plurality of metamaterial antenna panels each comprising an array of metamaterial cells, a feed network and an RFIC (radio-frequency integrated circuit) coupled to the feed network, wherein the RFIC generates a plurality of phase shifts for a plurality of signals, each signal radiated from a subarray with each phase shift;
- and
- an antenna controller that controls the plurality of metamaterial antenna panels to transmit and receive a plurality of beamforming signals at a plurality of phases to and from the satellite, wherein the plurality of beamforming signals received at the plurality of phases are combined in phase.
A phased array antenna system for use with a Low Earth Orbit (“LEO”) satellite constellation, comprising:
- a plurality of antenna panels, wherein each of the plurality of antenna panels comprises;
- an array of meta-structure cells;
- a feed network;
- and
- an RFIC (radio frequency integrated circuit) coupled to the feed network, wherein the RFIC generates a plurality of phase shifts for a plurality of signals, each signal radiated from a subarray with each phase shift;
- and
- an antenna controller that controls the plurality of antenna panels, the antenna controller configured to direct a first antenna panel to receive a first signal from a LEO satellite of the LEO constellation and a second antenna panel to receive a second signal from the LEO satellite of the LEO constellation.
