ELECTROMAGNETIC WAVE EMISSION NETWORK ANTENNA CARRIER OF AN ORBITAL ANGULAR MOMENT AND TRANSMISSION METHOD THEREOF

摘要

This array antenna (20) comprises a network (34) beam forming a plurality of transmission channels (v1,.., v4) connected to the network (34), a base comprising a plurality of radiating elements (e1,.., e4) connected to a transmission channel and able to emit elementary waves forming a carrier wave resulting from an orbital angular moment, and a unit (38) encoding. The antenna is characterized in that it further comprises a modulation unit (m2,.., m4) associated with a transmission channel (v1,.., v4) and being capable of shifting of a variable phase shift value of each elementary wavefrom to modify the topological charge of the carrier wave resulting, and in that the encoding unit (38) is connected to said modulation unit (m2,.., m4) in order to control its operation and adapted to form the signal encoded in the carrier wave resulting in determining the value of the phase shift switchable.
