Some considerations on lattice network-based lossless balanced Composite Right/Left-Handed transmission lines

Lattice network-based unit cells have been recently proposed for periodically loading conventional transmission lines as an alternative way to implement Composite Right/Left-Handed artificial transmission lines. In this contribution, some aspects of this new artificial transmission line are discussed. The availability of an equivalent simple lattice unit cell is discussed, and the capability to approximate by means of this simpler network, when the equivalence does not hold, is also presented.
