Abstract

In this paper we present the design of a 120 GHz 2×2 dipole array in a 130 nm SiGe technology, which employs dual mode substrate wave cancellation to improve radiation efficiency and to avoid uncontrolled radiation from the chip edges. We show a systematic analysis of the involved dielectric slab modes TM0 and TE1 and their effects on the radiation pattern and efficiency. Based on this, the position and orientation of the array elements are derived for optimal cancellation of substrate waves and different feeding techniques are compared. The dipole array shows a measured realized gain of 1 dBi (including GSG-pad, Balun and matching-capacitor, all on-chip), an S11-Bandwidth of 18 GHz and a realized gain bandwidth of 16 GHz. Very good correlation between simulations and measurements is achieved through careful modeling of the probe-effects. The presented results provide useful insights on the design of on-chip dipole arrays for future mm-wave applications in standard SiGe or CMOS technologies.
