A polarization dependent left handed metamaterial for telecommunication

[摘要] A polarization dependent, left handed metamaterial based on single layer patterned resonant structure intended for C- frequency band with 2.14 GHz wide bandwidth is proposed. The size of a single unit cell is 11 × 11 mm2 and the effective medium ratio is 5.27. CST Microwave Studio electromagnetic simulator is used to design and numerical analysis as well as Agilent N5227A VNA is for measurement. The measured results show resonance peaks at 5.17 GHz and applicable for IEEE 802.11a Wi-Fi and cordless telephone applications. The proposed metamaterial is explained by lumped circuit model and exhibits left handed characteristics at 6.43 GHz.
