| Abstract(in English) | A method for miniaturizing the branch-line hybrid-ring is presented by replacing the quarter wavelength transmission lines with a network consisting of a coupled line called microwave C- section and two single lines.In a homogeneous medium,the input matching,isolation and equal power split can be perfectly satisfied as in a conventional 3dB hybrid.However,in a inhomogeneous medium,generally speaking,those conditions will not be attained because of the unequal phase velocities of the even and odd modes.Therefore,this paper also shows the compensation method that the equal power split can be achieved by the proper selection of the coupled-line length and its coupling coefficient. And the input matching and isolation are hardly affected at a center frequency.Experimental results show good agreement with theories. |
