A micromachined double-dipole antenna for 122 – 140 GHz applications based on a SiGe BiCMOS technology

This paper presents an on-chip double-dipole antenna by applying micromachining techniques based on a standard SiGe BiCMOS process. It enables the fully integration of millimeter-wave transceiver and antenna into a single chip. A parametric study has been made in simulation which reveals the influence of the key design parameters over the radiation efficiency and directivity. A prototype has been fabricated and measured to verify the design. The measured peak gain is 8.4 dBi at 130 GHz with a simulated efficiency of 60 %. The 3-dB gain bandwidth is 122 – 140 GHz.
