Two-Section Cascaded Coupled Line Wilkinson Power Divider for Dual-Band Applications

A coupled line based design method is presented for the dual-band operation of the Wilkinson power divider. It is shown that a simple two-section cascaded coupled line structure is capable of the dual-band operation in the Wilkinson power divider. The overall divider structure can be simplified with the small number of transmission line sections and the coupled line using the proposed approach.
