Abstract
Description
technical field
[0001] The invention relates to an antenna, in particular to a one-dimensional circularly polarized antenna which realizes beam scanning in an electronically controlled manner and a control method thereof. Background technique
[0002] Electronically controlled beam scanning antennas can meet various application scenarios that require beamforming, such as satellite communications (including mobile communication), drones, driverless cars, 5G mobile communications, smart logistics and other fields. At present, most beam scanning antennas are in the form of active phased array antennas. Although they are very powerful, they use a large number of T / R components, resulting in complex systems and high costs, which limit their large-scale applications. In recent years, the methods to achieve electronically controlled beam scanning mainly include various reconfigurable methods based on loading active electronic switches or tunable materials, such as PIN diodes, varac...
