Dual-band Wilkinson power divider using cross-paired coupled lines

A novel Wilkinson power divider for dual-band operation is proposed. It is shown that the power divider consisting of cross-paired coupled-line structure is capable of operating at dual frequencies. The closed-form design equations for this proposed power divider are obtained by using even- and odd-mode analysis. For verification, the simulation and measured results of a microstrip power divider operating at 900 MHz and 2.45 GHz are shown and are consistent with each other.
