Four-way Chained Quasi-Planar Power Divider Using Rectangular Coaxial Waveguide

A novel quasi-planar four-way chained power divider using rectangular coaxial waveguide is presented. The rectangular coaxial waveguide consist of a rectangular outer conductor and a planar inner conductor that is a stripline suspended at the middle of the outer conductor. Moreover, the characteristic impedance of the proposed quasi-planar rectangular coaxial waveguide is analyzed. Four cross coupling units locating along the inner conductor are utilized to realize four-way power-dividing outputs. A four-way quasi-planar chained rectangular coaxial-waveguide power divider operating at C band is developed with reasonable agreement between the simulated and measured results.
