| Abstract: | A simple and successful method for miniaturizing a ring coupler is proposed. The size of the ring coupler is reduced by connecting multiple open stubs on the inside of the ring. There is no need of any lumped element, via hole or wire bond, but only microstrip lines. The reduced size is arbitrary and the results of the miniaturized ring coupler coincide with that of the traditional one. |
