The principle of electric resonance metamaterial design is analyzed in detail, and the designed metamaterial (H-shaped metamaterial) is significantly miniaturized due to the lowering in the operating frequency from 12.21 to 5.46 GHz while keeping the dimensions unchanged, which was achieved by means of equivalent inductance and capacitance loading and grounding based on the equivalent circuit model. Our work not only provides a reference for miniaturizing different metamaterial configurations, but also points out specific research directions and effective ways in the design of metameterials with different characteristics and different operating frequencies.
