Abstract

The invention discloses a separated lens antenna and communication equipment. One side of a dielectric lens is arranged to be a plane, the other side of the dielectric lens is arranged to be a convex face with the height changing in the single-dimension direction, and the dielectric lens is arranged at the position where the distance between the dielectric lens and a micro-strip radiation unit equals the focal length of the dielectric lens through a lens support, so that electromagnetic waves can be fully diffused when propagating between the micro-strip radiation unit and the lens, and when propagating to the dielectric lens, the electromagnetic waves can be radiated to the outer side of the dielectric lens only after passing through the convex surface of which the height changes along the single-dimensional direction; therefore, the phase change of the electromagnetic wave is changed only in a single-dimensional direction, and the phase change of the electromagnetic wave in other dimensional directions is not changed, so that the radiation gain of the antenna is enhanced, and the beam direction of the electromagnetic wave radiated by the microstrip radiation unit is ensured to be consistent with the beam direction of the electromagnetic wave emitted after passing through the dielectric lens. Therefore, continuous scanning of the antenna in the one-dimensional direction is realized.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an isolated lens antenna and communication equipment. Background technique [0002] With the development of 5G technology, the applicable field of lens antenna technology is also expanding. Such as increasing the gain of the antenna and the area for receiving electromagnetic waves by increasing the dielectric lens. However, the phase distribution mode of the conventional lens antenna structure is a concentric circle structure. Although this structure can maximize the use of the lens surface, the area of ​​the antenna aperture is increased to increase the antenna gain. However, this lens antenna has a narrow beam width and does not have the capability of one-dimensional continuous beam scanning, so it cannot be widely used in the millimeter wave field. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an off-body lens antenna ...
