  • Abstract
    This paper presents the design of a low-profile dielectric resonator antenna (DRA) for wideband systems. The antenna consists of three dielectric segments, each with different permittivity, residing over a ground plane. The impedance bandwidth of this DRA was enhanced by introducing an air-region inside the middle segment. The volume of the proposed DRA was reduced by adding a finite planar conducting wall. A full ground plane was used to ensure that most of the power radiates to upper hemisphere. The computed results show a VSWR bandwidth of 86% from 4.0-10.2 GHz, while peak gain is in the range of 5-7 dBi.
