A Novel Substrate Integrated Dielectric Resonator Antenna (DRA) fed by Substrate Integrated Coaxial Line for Millimeter Wave Application

In this paper, we present a novel substrate integrated dielectric resonator antenna (DRA) fed by Substrate Integrated Coaxial Line. In contrast to the traditional Dielectric Resonator Antenna (DRA) configuration, which has an extra cylindrical dielectric resonator as its primary radiating element, the presented technology utilizes the identical substrate as a feasible alternative to traditional Dielectric Resonator Antennas (DRAs), offering several advantages in terms of improved effectiveness, regulated radiation pattern, and compactness. The proposed methodology involves the implementation of DRA structure, which is achieved by utilizing a circular ring encased structure composed of metallic vias. The field distribution attained in the suggested Dielectric Resonator Antenna (DRA) has similarities to the H E M12 δ mode of the standard cylindrical DRA. The proposed DRA achieves a broadside unidirectional beam with a gain of 6.3 dBi at 28 GHz. The design technique proposed in this study facilitates the decrease in size and complexity of assembling a dielectric over the feed network, as compared to standard approaches. In essence, this work introduces a straightforward and inventive methodology for designing DRA (Dielectric Resonator Antennas) that effectively addresses the obstacles associated with fabrication and design of planar and compact designs in millimeter wave frequencies.
