Abstract
A novel high-gain dielectric resonator antenna (DRA) for wideband wireless applications is presented. The antenna is composed of a hollow cylindrical dielectric resonator (DR) inside which an assembly of two dielectric truncated cones having different permittivities are inserted. A suitable probe excitation system and an air gap, realized between the base of the first truncated dielectric cone and the ground plane, are used to further increase the antenna bandwidth. A full-wave commercial software based on the finite integration technique (FIT) has been used to analyze and design the antenna, while the singularity-extraction method (SEM) has been adopted to extract information about the main resonant processes taking place in the proposed radiating structure.| File | Dimensione | Formato | |
