Millimeter-wave stripline fed dielectric resonator antenna with assembly features

An approach to engineering of a high-gain spherical dielectric resonator antenna operating at around 35 GHz is discussed in this work. A stripline-based aperture-coupled feeding technique using stacked multi-layered printed circuit boards architecture has been demonstrated. Precise alignment of the spherical radiating element with respect to the feedline is ensured by an air-filled via in a supportive layer. For system assembly and packaging, a metal shielding layer is applied around the radiating structure. The final circuit design, including its packaging module, is tested to quantify its input impedance matching, radiation pattern, and efficiency. Necessary conclusions are drawn, and the shortcomings are addressed.
