Comparative Study of Different Structures of Wilkinson Power Divider

This paper aims to investigate various parameters of three widely used conventional Wilkinson power divider (WPD) topologies for equal power division: rectangular, circular, and triangular. The study provides valuable insights for design engineers in selecting the most suitable topology based on bandwidth (BW), power handling capacity, fabrication ease, compactness, and design complexity. These structures are analyzed using ADS Circuit, EM, and CST MWS simulations to evaluate their performance differences. The simulated and measured results demonstrate good agreement.
