Micromachined On-Chip Dielectric Resonator Antenna Operating at 60 GHz

This paper presents a novel cylindrical dielectric resonator antenna (DRA) suitable for millimeter-wave (mm-wave) on-chip systems. The antenna was fabricated from a single high-resistivity silicon wafer via micromachining technology. The new antenna was characterized using HFSS and experimentally with good agreement been found between the simulations and experiment. The proposed DRA has good radiation characteristics, where its gain and radiation efficiency are 7 dBi and 79.35%, respectively. These properties are reasonably constant over the working frequency bandwidth of the antenna. The return loss bandwidth was 2.23 GHz, which corresponds to 3.78% around 60 GHz. The antenna was primarily a broadside radiator with -15dB cross-polarization level.
