This paper shows 3-way wilkinson power divider using artificial-transmission-lines. The conventional wilkinson power divider has problem for size reduction and harmonics, because the conventional one is using quarter-wave length that are determined by operating frequency. The quarter-wave transmission lines show harmonics at fundamental frequency and integer multiple. The proposed divider is miniaturized and show higher-order mode rejection by using LUC(Low-pass filter unit cell) of artificial-transmission-lines. The LUC of artificial-transmission-lines show low-pass characteristic so that a circuit with LUC is show higher-order mode rejection. And, also LUC is adjustable component for electrical length and characteristics, shape. The fabricated divider work well and show harmonics rejection and compact design.
