Abstract
ABSTRACT In this paper, a novel, compact, low-profile miniaturized stacked Dielectric Resonator Antenna (DRA) for wideband applications is proposed. The design consists of two dielectric resonators of different dielectric constant stacked together. The Dielectric Resonators (DRs) are fabricated on the top side of the substrate (Taconic RF-35) with an inverted-trapezoidal patch as a feeding mechanism. The proposed configuration offers a wide impedance bandwidth of about 76.8%, covering the frequency range from 4.85 GHz to 10.88 GHz with TE21δ mode and TE23δ second higher-order mode being observed at the resonant frequencies of 6.14 GHz and 10.52 GHz, respectively. Peak gain of 8 dBi at 10.2 GHz is observed. The proposed antenna provides a wide impedance bandwidth, high radiation efficiency with smaller electrical size, and low profile of 0.19λg , where λg is the wavelength of the lower cut-off frequency.
期刊介绍：
Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance.
All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
