A novel compact power divider with harmonic suppression for phased array antenna application

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, such as power amplifier, in the complicated phase array antenna feeding network area. The proposed power divider achieves 20% size reduction compared to the conventional Wilkinson power divider and it is beneficial to the miniaturisation of the phased array antenna. From the measured results, it can be seen that the simulated results can instruct the practical circuit very well.
