Document Type and Number:
WIPO Patent Application WO/2023/273200
Kind Code:
A1
Abstract:
The present application provides a multi-mode phase shifting device and a large-scale array antenna. The multi-mode phase shifting device comprises: a bus and at least two branch lines. The at least two branch lines are connected to the bus; the bus is connected to an input end; the branch lines are connected to an antenna array; the bus is provided with a phase shifter; and at least one branch line is provided with a circuit breaking switch. Mode switching can be performed by providing the phase shifter and the circuit breaking switch, such that wave beam reconfiguration can be realized and switching between a wide wave beam and a narrow wave beam can be performed in a vertical plane, and wave beam pointing can be adjusted, thereby meeting different scene requirements.
