Achieving a wideband, efficient, scalable and low-cost interface between IC and antennas is critical for mm-wave transceivers in silicon. This paper presents an antenna-IC co-integration approach to achieve dual-polarization transmission and reception using on-chip dual-pol feeds that aperture-couple through a slot in the on-chip ground to a patch antenna on the back side of the IC. The proposed wafer-scale...
Advances in CMOS and SiGe technologies have made millimeter (mm)-wave multielement arrays with complex architectures, high yields, and good interelement matching feasible. However, the antenna-in-package approach is challenging with a larger number of array elements due to the increase in mm-wave I/O, the need for impedance-controlled via/routing symmetry. In this work, we describe an antenna-IC cointegration...
