Title: Antenna apparatus
Inventor: DU MINGDE
IPC: H01Q3/24
Filed: 2021-02-09
Abstract: Disclosed in embodiments of the present application is an antenna apparatus, which is applied in the field of communication. Embodiments of the present application comprise: a feed converts guided waves into beams and subsequently sends said beams to a defocus apparatus. The defocus apparatus may further alter the transmission direction of the beams. As such, the defocus apparatus, after altering the transmission direction of the beams, sends the beams to a form-shaping antenna face, the form-shaping antenna face alters an emission direction of the beams and an emission shape of the beams, and subsequently the beams are transmitted to an opposite end antenna, thereby achieving information transmission. The defocus apparatus, by means of altering the transmission direction of the beams, is able to realize an increase in spatial distance between a feed and another feed, which can reduce feed distribution density, avoid the occurrence of overlap in the physical locations of feeds, implement a sensible arrangement of feeds, and guarantee a communication effect.
