Optimum Design of a Six-Port Power Divider with Selectable Power Division Ratios

An effective design procedure is devised for the optimum design of a versatile and useful six-port planar microstrip power divider. An equivalent circuit is developed for the divider; which is composed of line sections and asymmetrical T-junctions. The method of least squares is applied to the equivalent circuit of the divider for its optimum design. This power divider is capable of providing various power division ratios for different combinations of the output ports (for example 3 or 2 outputs) for the same fixed design configuration. The power divider may then be fine-tuned by the full-wave software to obtain an optimum design for the divider. The method of least squares may also be used to design power dividers with arbitrary power division ratios at their output ports.
