    • 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.
    • 一种介质波导,设计用于避免电介质条连接部分电磁波反射的影响,并具有改进的特性。 将第三介质条插入连接部分的第一介质条和第二介质条彼此连接的部分中,并且确定所述连接部中的三个连接平面之间的距离,使得在 在第一和第三介质条之间的连接平面,在第一和第二介质条之间的连接平面处反射的波和在第二和第三介质条之间的连接平面反射的波被叠加,相位差为2pi / 3彼此。 或者或另外,第一介质条连接平面与第一至第三介质条连接面之间的距离设定为通过介质条传播的电磁波的引导波长的⅙, 第二介质条连接平面和第二 - 第三介质条连接平面被设置为导向波长的。。 因此,反射波彼此相对叠置以抵消。 以这种方式,将反射信号传播到端口是有限的。

    • A dielectric line converter which includes a dielectric stripline; an upper conductor surface and a lower conductor surface sandwiching the dielectric stripline; the upper and lower conductor surfaces having a first spacing in a first region along the dielectric stripline so as to form a first-kind dielectric line, a second spacing which is substantially zero in a second region so as to form a second-kind dielectric line, and a third spacing which is less than the first spacing in a line conversion region between the first and second regions. Grooves may be formed in the opposing surfaces of the upper and lower conductor surfaces, and the dielectric stripline may be arranged in the grooves. Impedance matching between the first-kind and second-kind dielectric lines is arranged n the line conversion region. The length of the line conversion portion may be set to be an odd multiple of &lgr;/4.
