In this paper, an ultra-wideband (UWB) Wilkinson power divider with ultra-narrow dual-notched bands is proposed. The multi-mode UWB characteristic is achieved using stepped-impedance open-circuited stub (SIOS) and broadside-coupled microstrip/CPW (BCMC) transition. Then, to cancel the interferences from existed wireless local-area network (WLAN) signals (i.e., 5.2 and 5.8 GHz), two pairs of embedded CPW resonators are employed. To verify the mechanisms mentioned above, an UWB power divider with dual-notched bands is implemented and fabricated. The measurement exhibits dual-notched bands with center frequencies of 5.28 and 5.86 GHz, which has merits of 10-dB notched FBW of 1.5% and 0.68%, respectively.
