発明の名称 (英語) NONRECIPROCAL TRANSMISSION LINE DEVICE AND ANTENNA APPARATUS NEW
発明の概要(英語) A nonreciprocal transmission line device (10) having mutually different propagation characteristics in forward and backward directions is provided with a plurality of unit cells (20) which are formed on a substrate having first and second surfaces facing each other, and are cascade-connected. Each of the unit cells (20) is provided with a grounded conductor (1) formed on the first surface of the substrate, an electromagnetic wave transmission line portion (11) formed on the second surface of the substrate, and a first parallel branch circuit (12) formed on the second surface of the substrate and equivalently including a capacitive element connected to the transmission line portion (11). Each of the unit cells (20) is magnetized in a magnetization direction different from a direction along the first and second surfaces of the substrate and different from the propagation direction of the transmission line portion (11) and has gyro anisotropy. Each of the first parallel branch circuits (12) is formed on one side of a plane passing through the transmission line portion (11) and formed by the propagation direction and the magnetization direction. The substrate comprises a magnetic substance (15) between each of the first parallel branch circuits (12) and the grounded conductor (1).
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, research related to non-reciprocal transmission line device is performed. The non-reciprocal transmission line device, in its forward and reverse direction, the non-reciprocal electromagnetic wave propagation to the (non-reversible). That is, in the forward direction, the electromagnetic wave is, the direction of the flow direction of power transfer phase is the same as each other (the right-handed mode) and the forward propagated as a wave, on the other hand, in the reverse direction, electromagnetic waves, the direction of the flow direction of power transfer and the reverse phase different from each other (left-handed mode) propagates as a wave. The present inventors have found, for example in Non-Patent Document 1 and Patent Document 1-3 and the like, some of the non-reciprocal transmission line device is proposed.
For example, Patent Document 1 is, at least one of the first non-reciprocal transmission line 1 1 and 2 connected in cascade between the first port of the microwave transmission line constituted by a transmission line microwave apparatus is disclosed. Is a non-reciprocal transmission line, the capacitive element of the series branch circuit equivalently including, which is equivalent to an inductive element and a circuit including the parallel branch. Is a non-reciprocal transmission line, relative to the direction of propagation of the microwaves is magnetized in the direction of magnetization different from the gyro that has anisotropy, the magnetization direction and the direction of propagation with respect to the plane formed by the asymmetrical structure. Lossy transmission line is, in the reverse direction propagation constant in the forward direction propagation constant different from that of the non-reciprocal phase so as to have properties, and an operating frequency and the propagation constant in a predetermined dispersion curve showing the relationship between the propagation constant and operating frequency becomes set.
