Abstract

A transmission-type electromagnetic surface unit disclosed by the present invention comprises a dielectric plate, a receiving electrode, an emitting electrode and a phase shifting structure; the dielectric plate comprises a first surface and a second surface far away from the first surface, the dielectric plate further comprises a first port and a second port far away from the first port, the first port is located on the first surface, and the second port is located on the second surface. the receiving electrode is arranged on the first port; the emitting electrode is arranged on the second port; and the phase shifting structure is arranged in the center of the dielectric plate and is respectively connected with the receiving electrode and the emitting electrode. A laminated array structure is characterized in that the laminated array structure comprises at least two transmission type electromagnetic surface units. Compared with the prior art, the antenna provided by the invention has the advantages of small unit loss, simple structure, wider bandwidth, larger beam scanning range and the like.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a transmissive electromagnetic surface unit and a laminated array structure. Background technique [0002] The electromagnetic surface is a new type of two-dimensional periodic or quasi-periodic artificial electromagnetic structure. The new reconfigurable electromagnetic surface constructed by introducing electric adjustment devices on the electromagnetic surface unit can realize real-time regulation of electromagnetic waves by controlling the electric adjustment devices, so that it can Realize multiple functions such as beam scanning and beam agility. The digital phased electromagnetic surface antenna based on the reconfigurable electromagnetic surface unit is one of the most typical technical points. Theory and engineering practice have shown that compared with the traditional phased array, although the phased electromagnetic surface antenna based on the electronically controlled recon...
