摘要

In this paper, L-type impedance matching networks (IMN) for lossless metamaterial transmission lines (MTLs) are designed effectively using an equivalent conjugately characteristic-impedance transmission line (CCITL) model and Meta-Smith charts. These MTLs can be implemented using lossless periodic transmission lines appropriately loaded with lossless lumped elements in each unit cell. Only passbands associated with the conjugate characteristic impedances of CCITLs with nonnegative characteristic resistances (NNCRs) are considered in this paper. It is found that the L-type matching networks are simple and practical for MTLs, and they are conveniently designed using Meta-Smith charts.
