Broadband circularly polarized dielectric rod antenna excited by a cavity backed spiral
Abstract This paper introduces a new broadband dielectric rod antenna with circular polarization that can be utilized in microwave imaging applications. The antenna utilizes a sine wave modulated Archimedean spiral to launch hybrid mode within the dielectric rod, resulting in a wide circular polariz...
