  • Abstract
    The phase difference between the coupled outputs is calculated in a 2nd-order approximation for asymmetric nonuniform line couplers. This result permits one to propose an even-mode characteristic-impedance variation for the design of a 0° coupler, which is more easily computable than the Klopfenstein taper previously used.
