The proposed ring hybrid bridge contains a ring. The length of the ring is equal to the average wavelength within the operating wavelength range. The ring is divided into four branches by transmission lines. One of the branches contains three sections of the transmission line - a central section and two side sections. The end parts of the central section are shunted by short-circuited loops. The length of the central section, the lengths of the short-circuited loops, and the lengths and the characteristic impedances of the side sections correspond to the parameters of a band-pas filter.
