Abstract
When a phase constant in a first mode of propagation in the forward direction is β, and a phase constant in a second mode of propagation in the backward direction is β, respective first and second electrical lengths of stub conductors are set so that a function of nonreciprocal phase shift amount β=(β−β)/2 with respect to an operating angular frequency comes close to a function βwith respect to an operating angular frequency, when beam squint of such a phenomenon that a radiation direction of electromagnetic waves radiated from a nonreciprocal transmission line apparatus changes in accordance with frequency does not occur in the vicinity of an intersection of a dispersion curve representing a relation between the phase constant βand the operating angular frequency and a dispersion curve representing a relation between the phase constant βand the operating angular frequency.
