Switchable dual-band dual-polarized VICTS antenna system for satellite communication on-the-move

A switchable dual-band dual-polarized variable inclination continuous transverse stub, (VICTS) antenna system for satellite communication on-the-move, wherein the VICTS antenna system is a layered structure, that comprises:

• a dual-band VICTS antenna subsystem,
• a dual-band dual-polarized polarization subsystem,
• a dual-band/ultra-broadband layered antenna radome, and
• a mechanical subsystem configured to control the switchable dual-band dual-polarized VICTS antenna system,
• wherein the mechanical subsystem is connected to the dual-band VICTS antenna subsystem and the dual-band dual-polarized polarization subsystem through motorized connection, including motors and belts,
• the dual-band VICTS antenna subsystem is the layered structure comprising two layers,
• one layer is a dual-band feed network, comprising a dual-band slow-wave structure and two transitions from rectangular waveguides to the dual-band slow-wave structure,
• the two transitions connect the rectangular waveguides as input/output to the dual-band slow-wave structure,
• the dual-band slow-wave structure is a two-dimensional groove grid structure, formed by orthogonally interweaving two single-band slow-wave structures of two bands,
• another layer is a dual-band VICTS electromagnetic radiator, created by orthogonally integrating two single-band VICTS electromagnetic radiators, while long sides of slots of the two single-band VICTS electromagnetic radiators are perpendicular to each other, forming a two-dimensional matrix structure of metal blocks through interweaving;
• the dual-band dual-polarized polarization subsystem comprises two linear polarizers and one circular polarizers;
• when the linear polarizer is activated, an orientation of an E-vector of an electromagnetic beam is rotated;
• when the circular polarizer works, a linearly polarized wave is converted into either a left-handed or a right-handed circularly polarized wave;
• the VICTS antenna system further includes air gaps between layers within the layered structure;
• the mechanical subsystem, comprising the motors and the belts, interfaces with both the dual-band VICTS antenna subsystem and the dual-band dual-polarized polarization subsystem to facilitate their operation;
• furthermore, the layered structure further comprises a supporting structure connected to the mechanical subsystem via an adapter mechanism.
