Design and realization of a two way microstrip Wilkinson power splitter

This paper proposes an improved approach for the design and realization of a compact microstrip Wilkinson power divider in the UHF frequency band. The circuit is simulated using dimensions obtained from the Wilkinson power divider theory but realizations based on these dimensions presented a shift in the frequency band of operation. To account for this frequency shift in the design phase, an approach based on planar (2D) electromagnetic simulation is used to take into consideration more physical factors such as the circuit geometry in the design phase. The behavior of the implemented Wilkinson power divider using this approach is as desired and the frequency shift issue is solved.
