Abstract

This paper presents a wideband dielectric resonator antenna (DRA) in the millimeter-wave (mmW) band due to the combination of multi-mode. Traditional aperture-coupled DRAs are excited by a regular rectangular aperture, which usually creates one mode and thus contributes to a narrow bandwidth. The proposed method widens the coupling aperture under the DRA, which excites both fundamental mode and higher-order mode of the DRA simultaneously. This results in good impedance matching over a wide frequency range. In addition, it solves the bandwidth limitation of a DRA element in high frequencies. To increase the number of modes, a parasitic metallic patch is placed on the top surface of the DRA. By combining the fundamental mode and the higher-order mode of the DRA with the patch mode, the proposed antenna element achieves a wide impedance bandwidth of 41.5% from 24.7 to 37.6 GHz (for the reflection coefficient ≤ -10 dB) with a maximum gain of 7.8 dBi. Throughout the entire operating band, stable broadside radiation patterns with cross-polarization levels under -35 dB (E-plane) and -18 dB (H-plane) are observed. © 2023 IEEE.

Traditional aperture-coupled DRAs are excited by a regular rectangular aperture, which usually creates one mode and thus contributes to a narrow bandwidth. The proposed method widens the coupling aperture under the DRA, which excites both fundamental mode and higher-order mode of the DRA simultaneously. This results in good impedance matching over a wide frequency range. In addition, it solves the bandwidth limitation of a DRA element in high frequencies. To increase the number of modes, a parasitic metallic patch is placed on the top surface of the DRA.
