Abstract
A novel design of compact dielectric resonator antenna (DRA) dedicated to ultra wideband applications such as Digital Video Broadcasting-Handheld (DVB-H) is presented in this paper. A miniaturization technique has been performed in order to reduce the antenna size. The obtained dimensions of the final design of the DRA are λ0/7 × λ0/13 × λ0/28 at 466MHz. Also, measurements are presented to validate the results obtained via simulation. The proposed antenna offers a bandwidth of 70% around 700MHz for −8dB impedance bandwidth definition and covers the Ultra High Frequency (UHF) IV, V and Global System for Mobile communications (GSM) bands. Finally a DRA using magneto-dielectric materials is presented and its performances are shown.
