    摘要： A dielectric line switch is provided which is capable of easily controlling the propagation of an electromagnetic wave. Also provided is an antenna device employing said dielectric line switch. As an embodiment of the invention, a plurality of dielectric lines and a plurality of primary radiators are provided on a rotary unit. With the rotation of the rotary unit, the dielectric lines are switched ON and OFF by virtue of mechanical means, so that a desired change-over may be effected among the plurality of primary radiators in a time sharing manner, and the positions of the primary radiators may be shifted within a plane of the focal point of a dielectric lens, thereby enabling the transmission wave beam and/or reception wave beam to scan in a desired manner.

    摘要： A dielectric waveguide designed to avoid the influence of reflection of electromagnetic waves at connected portions of dielectric strips and to have an improved characteristic. A third dielectric strip is inserted in a part of a connection section at which a first dielectric strip and a second dielectric strip are connected to each other, and the distances between the three connection planes in said connection section are determined so that a wave reflected at the connection plane between the first and third dielectric strips, a wave reflected at the connection plane between the first and second dielectric strips, and a wave reflected at the connection plane between the second and third dielectric strips are superposed with a phase difference of 2&pgr;/3 from each other. Alternatively or in addition, the distance between the first-second dielectric strip connection plane and the first-third dielectric strip connection plane is set to ⅙ of the guide wavelength of an electromagnetic wave propagating through the dielectric strips, and the distance between the first-second dielectric strip connection plane and the second-third dielectric strip connection plane is set to ⅙ of the guide wavelength. Reflected waves are thereby superposed in phase opposition to each other to cancel out. In this manner, propagation of a reflected signal to ports is limited.

    摘要： In a directional coupler comprising two separated dielectric guides, reflection and loss in the separation position (separated faces) is reduced. Furthermore, the beam of an antenna device comprising a primary emitter and a dielectric lens can be tilted quickly even by a low-torque motor. A moving portion and a fixed portion each comprise dielectric guides, and in addition, grooves are provided in opposing end faces of conductive plates thereof, at a distance from the electrode faces of the dielectric guides of approximately an integral multiple of half the wavelength of the transmitted waves. Furthermore, the dielectric guide of the directional coupler portion is a normal NRD guide, and the dielectric guide of another portion is a hyper NRD guide.

    摘要： A dielectric waveguide has a plurality of dielectric ceramic sheets each having a high-dielectric-constant portion and a low-dielectric-constant portion. The dielectric ceramic sheets are laminated and baked and electrode films are formed on the outer surfaces thereof. Thus, a dielectric waveguide is obtained in which the high-dielectric-constant portion serves as a propagating area and the low-dielectric-constant portion serves as a non-propagating area.

    摘要： In a millimeter wave module or the like having both a normal NRD guide and a hyper NRD guide, a conversion portion structure for non, radiative dielectric waveguides of different types has excellent conversion characteristics at the connection between the two types of NRD guides. In a first conversion portion, the width of a dielectric strip is changed from the width of a dielectric strip in the hyper NRD guide portion to the width of a dielectric strip in the normal NRD guide portion, grooves of approximately the same depth as grooves in the hyper NRD guide are provided extending as far as the second conversion portion, and in a third conversion portion, the width of these grooves widens perpendicular to the propagation direction of electromagnetic waves and parallel to the face of conductive plates. According to this structure, guide conversion can be achieved with low radiation in a predetermined frequency band.
