Abstract

The invention discloses a transmissive electromagnetic surface unit, comprising: a medium plate, the medium plate includes a first surface and a second surface far away from the first surface, the medium plate further includes a first port and a distance away from the first surface the second port of the first port, the first port is located on the first surface, the second port is located on the second surface; a receiver electrode, the receiver electrode is arranged on the first port; an emitter electrode , the emitter is arranged on the second port; the phase-shift structure is arranged in the center of the dielectric plate, and is respectively connected with the receiver and the emitter. A layered array structure, characterized in that, the layered array structure includes at least two of the transmissive electromagnetic surface units. Compared with the existing solution, the present invention has the advantages of small unit loss, simple structure, wider bandwidth and wider beam scanning range.

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...
