Abstract:
This communication presents a 60-GHz circularly-polarized antenna-in-package in a low-temperature co-fired ceramic technology. It integrates 4 ×4 aperture-coupled corner-truncated microstrip patch antenna elements and their stripline feeding network as well as signal and ground traces for interconnection with the chip and board. The fabricated sample has a dimension of 13 ×13 ×0.9 mm 3 . Simulated and measured results confirm its sufficient gain and matching bandwidth for broadband 60-GHz applications (57-66 GHz).
