A 60-GHz Circularly-Polarized Array Antenna-in-Package in LTCC Technology

摘要

This communication presents a 60-GHz circularly-polarized antenna-in-package in a low-temperature co-fired ceramic technology. It integrates 4$times$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 $times$13 $times$0.9 mm $^{3}.$ Simulated and measured results confirm its sufficient gain and matching bandwidth for broadband 60-GHz applications (57–66 GHz).
