A novel dual‐band Wilkinson power divider (WPD) is designed for the purpose of operating at two arbitrary frequencies. The theory and design procedure of the novel component are presented in detail. For demonstration, a dual‐band WPD with operating frequencies of 1.0 and 2.6 GHz is proposed, fabricated and tested. The good agreement between the measured and simulated results confirmed the design concept. Measurements show that insert losses both at the two central frequencies are less than 3.3 dB. Both return loss and port isolation have good performances, which are more than 21 and 28 dB separately. [ABSTRACT FROM AUTHOR]

A novel compact structure for dual-band Wilkinson power divider has been proposed. The power divider consists of a single line, two coupled lines and four lumped elements. Using even- and odd-mode analysis, the design equations have been obtained through rigorous derivation. The odd-mode impedance Z o is a free variable here, it can be used to control the coupling between the coupled lines, as well as the values of the inductor and capacitor. This provides much flexibility and convenience to our design. Moreover, it significantly widens the frequency ratio to be 10 or even more. [ABSTRACT FROM PUBLISHER]
