Abstract

An unequal power divider with substrate integrated waveguide technology has been designed. This structure is compact in size and has the capacity to develop to the n-port unequal power divider. Its output powers ratio is also adjustable. The output powers can be easily change by varying the width of the output ports. The design procedure has been done analytically. Then a two-way unequal SIW power divider is designed. Simulation results of the proposed structure shows that return loss is below than10dB from 9GHz to 11 GHz. Transitions show that there is approximately 2 dB difference between output ports from 9.2GHz to 10.4 GHz.
