Abstract: In this paper, a miniaturized Wilkinson power divider using a novel technique for nth harmonic suppression is presented. In this technique, a novel low-pass filter (LPF) is inserted into each quarter-wavelength transmission line of the conventional Wilkinson power divider and open stubs are used at each port. For verification, the proposed 1 GHz power divider and the miniaturized LPF are fabricated and measured. The presented structure not only impressively suppresses the harmonics (2nd–12th) with high levels of attenuation, but also significantly reduces the size over 71% of the conventional one. The overall size of the fabricated power divider is only 14.1 mm × 18.2 mm (0.06 λg × 0.08λg).
