Abstract : A microstrip hybrid ring coupler providing the same function as a conventional magic Tee in waveguide or a coaxial rat-race is described. The ring is comprised of four equal electrical length arcs between the input-output ports. The 180 degree phase shift is introduced in one of the four ring arcs by a tightly coupled parallel strip conductor which extends towards the interior of the ring and has an electrical length of gamma/4 where gamma is the wavelength at the midband operationg frequency of the coupler.
