Abstract :
The waveguide /spl pi/-junction with an inductive post is utilized as the element of a multiple-way power divider in a slotted waveguide array. Based on the port reflection coefficient method (PRCM), an efficient fullwave approach is proposed for the accurate characterization of the /spl pi/-junction. Scattering behaviors of the four-port junction are provided as a function of the geometric dimensions of the structure, and they are helpful for the design of power dividers using this /spl pi/-junction configuration. The results are compared with available data, and good agreement is found.<>
