摘要：
This paper presents the analysis of 2-dimensional guided mode propagation in a finite 3-dimensional dielectric rod antenna. An approximated model based on the summation of the guided modes multiplied by the coefficients obtained by projecting the 3D fields on the 2D fields is derived and the accuracy of that is investigated. The factors playing role in the error of the approximation are studied and concluded that the main cause of error in the approximation is the reflection from the truncation at the end of the rod rather than the radiating field along the rod.
