An eight-port X-band power splitter based on binary Wilkinson power splitter topology is presented in this paper. The proposed power splitter consists of three stages, with one, two, and four equal power splitters in the first, second, and third stages, respectively. The input power is divided equally between the eight outputs to provide an equal-split power splitter. Evaluation of the structure is carried out using even-and odd-mode techniques. An epoxy laminate FR4 substrate with thickness of 0.5 mm is chosen, while the designed power splitter is simulated using Keysight Advanced Design System 2019 and ANSYS High Frequency Structure Simulation. As the results indicate, excellent performance is obtained for the power splitter, with a reflection coefficient of-36.5 dB and an insertion loss of-9.32 dB at the 9.65 GHz center frequency. The proposed power splitter has the potential to be employed in radar and microwave systems, specifically in phased-array structures.

In this paper, a Wilkinson 8-port unequal power splitter with symmetric power division among corresponding ports is investigated. Simulation and fabrication results show desirable power transmission at central frequency of 9.68GHz. This power splitter has transmission power of -13.25dB at corresponding ports 2 and 9, -11.4dB at ports 3 and 8, -10.36dB at ports 4 and 7, -9.7dB at ports 5 and 6. In addition, the proposed power splitter is suitable for feeding the array antenna due to its -16dB return loss and it minimizes return loss.
