Additively Manufactured Embedded Dielectric Resonator Antennas for 6G Applications

We present a new approach for designing embedded multi-band dielectric resonator antennas (DRAs) by exploiting the capability of modern additive manufacturing to create heterogeneous dielectric materials. To demonstrate the feasibility of our proposed approach, we present a dual-band DRA operating at 6G mid-band frequencies, and we show that the proposed embedded DRA achieves dual-band coverage with desirable boresight beam at both frequency bands. Moreover, while in this design we only used one small DRA embedded in a larger DRA, our proposed approach can be easily expanded to create multi-band or broadband DRAs by utilizing multiple embedded DRAs.
