Abstract:
In this paper, a novel modified Wilkinson power divider without transmission line stubs (such as short-circuit stubs and open-circuit stubs) and reactive components (such as isolation inductor L and capacitor C) is developed for dual-band applications. This symmetric power divider consists of six sections of transmission lines and an isolation resistor, and the corresponding nonlinear design equations are derived by using the even- and odd-mode analysis. Moreover, by solving the final nonlinear design equations, accurate numerical design data along with different frequency ratios are obtained, and the effective normalized parameters are given simultaneously in the figure and table formats for specific applications. To theoretically verify the design parameters, an ideal equal power divider operating at both 900 MHz and 5.85 GHz is simulated. Finally, the proposed structure and design method are validated by simulated and experimental results of a typical microstrip planar power divider operating at both 1 GHz and 3.5 GHz.
