Abstract
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. The distance L between connection planes between pairs of dielectric strips adjacent in the direction of propagation of an electromagnetic wave is set to an odd number multiple of ¼ 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.
