Abstract

This letter reveals a $30 \times 18$ mm2 metamaterial unit cell using coupled rectangular split-ring resonator (SRR), fabricated on only one side of the epoxy resin fiber substrate material. The proposed design consists of two separate SRRs outside and three split array rectangles with a small rectangle inside. It gives a wide magnetic repose throughout the C-band (4-8 GHz) microwave frequency spectrum. In the lower frequency band, the inclusion shows a negative epsilon, and in the upper frequency band, it shows double-negative characteristics (bandwidths of 0.72, 0.52, 0.2, and 0.71 GHz) with low losses in the C-band frequency range. The perceptible novelty of the proposed metastructure is achieved negative permeability throughout the whole C-band maintaining an effective medium ratio of 4.5.
