TL;DR: In this article, the coupling properties of uniformly coupled dielectric image lines of rectangular cross section are calculated employing an exact method for the determination of the phase constants of the even and the odd modes.
Abstract: In this paper the coupling properties of uniformly coupled dielectric image lines of rectangular cross section are calculated employing an exact method for the determination of the phase constants of the even and the odd mode. The theoretical results are verified experimentally. The results are also applied to the calculation of the coupling characteristics of practical dielectric image line directional couplers.

TL;DR: In this paper, the insertion loss due to radiation curved dielectric image lines of rectangular cross section was measured for the frequency range from 26 to 90 GHz and a minimum acceptable curvature radius as a function of the frequency was calculated employing the field distributions of straight dielectrics image lines and is compared with measurements.
