Based on bionics, we design and analyze the left-handed (LH) characteristics of meta-elements with leaf-shaped structure. The double negative (DNG) frequency band of the initial leaf-shaped LH structure is 5.77-6.17 GHz with a fractional bandwidth of 6.7%. Inspired by two overlapping leaves, and bas...
