• A radial power splitter is used to distribute signal power to the following stages locating radially around all directions. A well-known disadvantage of a radial power splitter implemented on a planar circuit board is the poor performance in output matching and output port isolation. An eight-way radial power splitter including the proposed ring-shape isolation network is presented. The ring-shape isolation network, comprising several series high-impedance lines and capacitors, plays the crucial role of significantly improving output matching and isolation of the eight-way power splitter. The background principle and design of the ring-shape isolation network are described. An eight-way radial power splitter is designed, simulated and fabricated on a printed circuit board. The measurement results, decently matching the simulations, show the input and output reflection coefficients as low as –20 dB at 1 GHz. The measured output isolation coefficients are below –20 dB at 0.7–1.14 GHz between any two output ports, exhibiting the widest isolation bandwidth among the reported radial power splitters.
