A power divider using linear electric probes coupling inside conducting cylindrical cavity

This paper presents theoretical and experimental analysis of the input impedance of a power divider using linear electric probes inside a conducting cylindrical cavity. An analysis begins with the integral equations of electric field intensities that can be formulated by applying the Field Equivalence Principle together with the boundary conditions at all the probes. The dyadic Green function that is the impulse response is derived and Method of Moments is used to solve for unknown current densities in the integral equations. Numerical results of input impedance, reflection coefficient and standing wave ratio of feed probe and power dividing probes for various probe lengths are investigated. The effects of length for feed probe and power dividing probes are studied for determining the maximum power transfer condition.
