A full-duplex User Terminal Panel (UTP) including one or more User Terminal Modules (UTM) having a plurality of Tx antenna elements. Each of the Tx antenna elements spaced apart from one another by a distance dTx. The full-duplex UTP further includes a plurality of Rx antenna elements. Each of the Rx antenna elements are spaced apart from one another by a distance dRx. Furthermore, the Tx antenna elements may be spaced according to a Tx lattice dTx, such that the Tx lattice dTx spacing arrangement provides grating lobe-free scanning in an elevation plane at a Tx frequency range. The Rx antenna elements are spaced according to an Rx lattice dRx, such that the Rx lattice dRx spacing arrangement provides grating lobe-free scanning in an elevation plane at a Rx frequency range.

Antenna lattice with unequal spacing for single-panel full-duplex satellite user terminals

Antenna lattice for single-panel full-duplex satellite user terminals

Disclosed embodiments relate to communicating with satellites at any elevation. In one example, an antenna system includes two or more user terminal panels (UTPs). Each of the UTPs include multiple user terminal modules (UTMs). The UTPs may be arranged in either a fixed, an adjustable geometry or a combination thereof. A UTM has multiple user terminal elements (UTEs) that include antennas and active circuits. An antenna may either generate an incoming signal in response to incident radio waves received from a satellite and/or may transmit an outgoing signal toward the satellite. Each active circuit is configured to process the incoming and outgoing signals. Also, the antenna system may include a control circuit configured to control signal processing performed by the active circuits. The UTPs may be operably connected to a single satellite, or different UTPs may be operably connected to different satellites.

User terminals with enhanced performance at low elevation angles for LEO and GEO satellites

Disclosed embodiments relate to modular antenna systems. In one example, an antenna system includes M user terminal elements, each being application-agnostic and including an antenna either to generate an incoming signal in response to incident satellite radio waves or to transmit an outgoing signal, and an active circuit to process the incoming and outgoing signals, a control circuit to control the processing performed by the M active circuits, and N user terminal modules (UTM) each including a daisy-chain of O of the M active circuits, each UTM further including a buffer placed after every P active circuits in order to correct any degradation that has occurred in the daisy-chain, and wherein M can be adjusted so that an antenna area and a corresponding throughput and bandwidth available to an application are adjustable and scalable.

Scaling power and control signals in modular satellite user terminals

Reduced scan loss antenna systems for communicating with satellites at low elevation angles

Disclosed embodiments relate to isolation methods for full-duplex communication. In one example, a full-duplex antenna system includes a Tx (transmit) signal path including one or more elements each, means a power amplifier, one or more filters, and a Tx port of a Tx patch antenna operating at a Tx frequency band to transmit an outgoing signal to a satellite, the one or more elements each further including an Rx (receive) signal path including a low noise amplifier driven by an Rx port of an Rx patch antenna operating at an Rx frequency band to receive an incoming signal from the satellite, the Rx frequency band being separated by a guard band from the Tx frequency band, wherein the filters together with a physical separation between the Tx and Rx signal paths provide sufficient isolation to reduce coupling between the Tx signal path and the Rx signal path, allowing the full-duplex antenna system to operate in full-duplex.
