Abstract

New explicit formulas for calculating the scattering parameters of a modified hybrid‐ring directional coupler are presented. It is also shown how port junction discontinuities of real couplers of this type, employed as equiphase antenna dividers, can be effectively compensated by using a pair of short open‐circuited transmission line stubs. The efficacy of the proposed approach is illustrated both by theoretical and by experimental results. © 1995 John Wiley & Sons. Inc.
