Analysis and Design of a Power Divider Using Metamaterials

Left-handed transmission lines (LHTLs) are used in this letter to design a novel Wilkinson power divider. In our design, the lumped L-C LHTLs (-λ/4) is instead of the right-handed transmission lines which is used as branch arms of the conventional Wilkinson power divider. The simulated results show that the novel power divider has a wide bandwidth of return loss and isolation, and its size is 50% smaller than conventional Wilkinson power dividers. The novel Wilkinson power divider has many advantages over conventional power divider in e.g. the size, weight, simplicity, low insertion loss, bandwidth of isolation, and cost.
