Abstract

A novel compact left-handed transmission line (LH-TL) metamaterial without vias or virtual ground is proposed in this paper. Based on the theory of hollow waveguide left-handed metamaterial and photonic bandgap (PBG), improved double split ring resonators (SRR) with electric connections among periodic cells patterned on the microstrip line is investigated. Compared with conventional SRR bulk left-handed metamaterials, this new structure does not have extra rods besides SRR so as to simplify design and fabrication on planar circuits. The dispersion characteristics are calculated by full wave simulation, results show that a phase advance (negative phase velocity) of the planar metamaterial in a relative bandwidth of over 25%. The influence of some parameters for LH-TL to the left-hand passband is also analyzed.
