Abstract :In this paper a Wilkinson power divider WPD is presented with ultrawide-band operation and harmonic suppression. This WPD is designed using coupling lines and meandered open stubs at main branches. The center frequency of the presented WPD is 4.25 GHz, which is fabricated and measured on RT/Duroid substrate with dielectric constant of 2.2. The proposed WPD provides good filtering band with high attenuation level. The 15 dB return loss operational bandwidth BW of the WPD is obtained between 3.2 GHz and 5.3 GHz, which shows 50% operational bandwidth
