Abstract: When a phase constant in a first mode of propagation in the forward direction is βp, and a phase constant in a second mode of propagation in the backward direction is βm, respective first and second electrical lengths of stub conductors are set so that a function of nonreciprocal phase shift amount βNR=(βp−βm)/2 with respect to an operating angular frequency comes close to a function βNRZ with 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 βp and the operating angular frequency and a dispersion curve representing a relation between the phase constant βm and the operating angular frequency.

Abstract: In a circularly polarized wave antenna apparatus including a non-reciprocal transmission line apparatus having forward and backward propagation constants different from each other, the non-reciprocal transmission line apparatus includes a transmission line part for a microwave, a series branch circuit equivalently including a capacitive element, and a shunt branch circuit branched from the transmission line part and equivalently includes an inductive element. The non-reciprocal transmission line apparatus is formed in a nonlinear shape and magnetized in a magnetization direction different from a propagation direction of the microwave. The non-reciprocal transmission line apparatus includes first and second reflectors provided at both ends of the non-reciprocal transmission line apparatus, respectively, and reflecting a signal; and satisfies that a phase difference between each pair of line parts located at positions opposed to each other across a substantially central part of the non-reciprocal transmission line apparatus is substantially 180 degrees.
