In this letter, a compact design of electric meta‐atom has been proposed as a dual band negative permittivity metamaterial. Compared with the earlier work, the proposed dual band meta‐atom has a better coupling strength at both the resonances and it is also more compact. This dual band design utilizes the mechanism of the resonance coupling between a meander line loaded delta loop meta‐atom and a rectangular close ring meta‐atom. The proposed meta‐atom is designed and investigated by both simulation and experiment with good agreement. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1152–1156, 2015
