Design of Dual-band Substrate Integrated Waveguide Dielectric Resonator Antenna in D-band

This work proposes a dual-band dielectric resonator antenna (DRA) for D-band millimeter wave frequency applications. The proposed design is fed from a planar substrate integrated waveguide (SIW). The antenna is designed to operate between 126.95 GHz – 136.5 GHz and 139.67 GHz – 149.48 GHz frequency bands. The proposed antenna achieves a bandwidth performance of 7.2% and 6.78% in the lower and upper-frequency bands respectively. The proposed antenna achieves a simulated gain performance of 10.69 dBi and a peak efficiency of 87% with stable broadside radiation patterns in both bands.
