This paper presents a compact power divider using microstrip-slotline transition technology. By using the microstrip-slotline transition, the ${\lambda}/4$ transmission lines of the divider can be changed to two ${\lambda}/8$ transmission lines in the multilayer structure. In the microstrip-slotline transition, we have used via holes to make a short circuit at the microstrip line and embedded spiral configuration stubs to reduce the electrical length of an open circuit at the slotline end point. For validating the microstrip-slotline technique, we have simulated and implemented the power divider with embedded spiral and via hole configuration circuits at a frequency of 2 GHz. Good agreement between the simulation and the measurement results is obtained at the operating frequency.
