Abstract
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.
