Abstract
The dielectric resonator antenna (DRA) has revolutionized the latest generation of communication systems with their obvious advantages of small size, bandwidth, and power-consuming capabilities. In this paper, an analysis of the impact of the dielectric material on the radiation characteristics of the DRA is presented with simulation reports. The proposed antenna takes the shape of a circular patch with the dielectric resonator having different shapes. This helps to analyze the impact of the tapering adjustments on the features of the antenna. The simulations are performed using the latest version of the complex electromagnetic modeling tool, and results are analyzed in terms of simulated reports like reflection coefficient (S11), voltage standing wave ratio, radiation patterns, and field distribution plots. The overall size of the proposed antenna is 18 &times; 12 mm<sup>2</sup>. The measured results are in good agreement with the simulation results. The proposed DRA is suitable for mobile wireless applications.
