Abstract

The invention provides a dual-polarization plane reflective array antenna. The antenna comprises a dual-polarization feed source used for emitting dual-polarization electromagnetic waves and a plane reflective plate used for focusing and modulating the incident dual-polarization electromagnetic waves, wherein the reflective plate comprises two or more than two reflective arrays; the reflective arrays form one or more phase-shifting units for performing phase shifting; and the plane reflective plate has convergence capability for the dual-polarization incident electromagnetic waves within a preset angle range in the normal direction of the reflective plate.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-polarized planar reflectarray antenna. Background technique [0002] Due to the flexible and mobile requirements of large-capacity communication systems in modern society, the disadvantages of traditional parabolic reflector antennas, which are bulky and bulky, have become increasingly apparent. For this reason, foreign scholars have proposed the concept of array reflective antenna. This array reflective antenna has the common advantages of reflective antennas and array antennas. Its basic structure is a single-layer or multi-layer periodic array composed of a large number of passive resonant or non-resonant elements, and then a feed source illuminates the array. By adjusting the scattering phase of each unit on the dielectric plate for the incident wave, the equal phase plane in a specific direction can emit a highly directional beam. In addition, for modern communicat...
