Abstract
This paper presents the design and simulated performance analysis of a novel 8-way power combiner. The study focused on the analysis of the combiners’ suitability for working operation at millimeter wave frequencies. The design of a waveguide to microstrip transition 4-way PC is first introduced. Then, a novel 8-way combining architecture is presented. This configuration covers a bandwidth of approximately 4.5 GHz, within the 28 to 32.5 GHz frequency range. Simulation results validate the effectiveness of the proposed design, demonstrating a high efficiency of approximately 90% and low insertion loss within the target frequency range of 28–32 GHz.
