Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a high pointing precision design method of a circularly polarized mesh antenna based on electromechanical integration optimization in the field of radar antennas. Background technique [0002] Circularly polarized antennas are often used in spaceborne antenna designs. Due to the unique structural characteristics of the spaceborne offset reflector antenna, the far-field pattern of the offset reflector antenna will produce a beam tilt phenomenon under circular polarization excitation. As the mesh antenna is gradually applied to the spaceborne antenna due to its light weight and small volume, the beam tilt phenomenon will also appear in the mesh antenna excited by circular polarization. This will seriously affect the pointing accuracy of circularly polarized mesh antennas, which in turn will affect the applications of mesh antennas in satellite communications, deep space ...
