Broadside radiating dielectric rod antennas with dielectric radiating elements

Abstract

A novel antenna which is comprised of collars made of high dielectric material slipped onto a cylindrical dielectric rod is presented. This antenna can be made to radiate broadside (unlike traditional rod antennas which radiate towards endfire). An accurate computer model based on a complex conjugate Galerkin method is also described. Measured and predicted antenna patterns are presented to verify the accuracy of the model and to demonstrate that the antenna under study is simple, feasible and effective.
