Abstract

A novel four-way multilayer substrate integrated waveguide (SIW) power divider with slot coupling structure is proposed in this letter. Two rectangular slots located in the right and left arms of SIW T-junction are employed to achieve efficient transition with two microstrip lines. Good impedance matching and signal transmission between SIW and microstrip lines are achieved. Two isolation resistors are used to improve the isolation between output ports. The even- and odd-mode analysis method is used in the proposed circuit. A prototype of the presented power divider is designed, fabricated, and measured. The measured results show a reasonable agreement with the simulated ones.
