This paper presents a novel compact power divider with third harmonic suppression and also can provide a direct current(dc) path which could simplify the other active circuits in the complicated phased array antenna system. The proposed power divider achieves 20% size reduction compared to the conventional Wilkinson power divider. From the measured results, it can be seen that the simulated results can instruct the practical circuit very well.
