The simple-loop hybrid ring is the simplest structure among the various kinds of hybrid circuits for microwave operation. It has four ports and is divided into four parts, each of length l, l being equal to a quarter wavelength at the operating center frequency f_<0->. By varying the characteristic admittance of each side, the authors have already proposed a generalized simple-loop hybrid ring in which the length of each side is not restricted to l at f_<0->. In this study we have experimentally designed and made several configurations of the generalized simple-loop hybrid ring of two sections in cascade according to the proposed design theory and measured the four basic frequency characteristics i.e., reflection coefficient at each port, isolation between input (output) ports, voltage ratio and phase difference between output voltages. They agree fairly well with the theoretical values.
