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...
