A novel technique for harmonic suppression and size reduction in planar Wilkinson power divider is presented. The proposed technique served by a microstrip electromagnetic bandgap element (MEBE) is used to reject the unwanted harmonics by employing its stopband effect and to reduce the length of microstrip by utilising its slow-wave effect. The whole size of the proposed divider has been reduced by 39% compared to the conventional power divider. Higher harmonics are effectively suppressed.
