Abstract: The design and analysis of a dual-band equal-split Wilkinson power divider are presented in this paper. It is proved that a coupled line with a pair of stubs structure is capable of the dual-band operation in the Wilkinson power divider. Moreover, the overall structure of power divider can be simplified with small number of transmission line sections using the proposed method, and the proposed divider can achieve dual-band operation over a wide range of band-ratios. For verification, a microwave power divider operating at 1 and 2.5 GHz is fabricated, and the experimental results show that the designed power divider fulfills all the features of a conventional Wilkinson power divider, such as an equal power split and impedance matching at ports.
