Circularly polarized equal-flux radiating antenna and wireless communication system

Abstract

The invention discloses a circularly polarized equal-flux radiation antenna and a wireless communication system, the antenna comprises a feed network, a dielectric substrate, a floor, a feed source and a dielectric lens, the dielectric substrate and the floor are superposed, and the feed network is arranged at one side, far away from the floor, of the dielectric substrate; the feed source is arranged on one side, far away from the dielectric substrate, of the floor, and the feed source is connected with the feed network; the dielectric lens is arranged on the floor and covers the feed source, the side, away from the floor, of the dielectric lens is in the emergent direction of circularly polarized electromagnetic waves, the dielectric lens is used for adjusting the phase of the circularly polarized electromagnetic waves, and field distribution on the aperture field surface of the dielectric lens meets corresponding near-field distribution, so that circularly polarized equal-flux radiation beam forming is realized. According to the technical scheme, circular polarization equal-flux beam forming can be achieved, the beam forming device has the advantages of being simple in structure, good in beam forming performance, obvious in out-of-beam suppression effect and the like, and the requirement of a wireless communication system for equal or approximately equal signal intensity coverage of a coverage area can be met.
