Abstract: The dielectric resonator antenna (DRA) in a stacked configuration with a finite ground plane is presented in this paper. The proposed DRA is axisymmetric and is excited by coaxial probe feeding technique. Here broadside radiation pattern is obtained for exciting 𝑯𝑬𝑴𝟏𝟏𝜹 mode of DRA by locating the coaxial feed at the off-axis position. This work mainly focuses on the improvement in the bandwidth of DRA. The analysis of the antenna with far-field radiation characteristics is performed. A −𝟏𝟎 𝒅𝑩 bandwidth of 44.88% is realized for the stacked DRA arrangement with suitable feed and selection of the dielectric resonator parameters. The proposed two-layer DR antenna can be appropriate for X-band applications.
