A 60-GHz on-chip slot-array antenna in integrated-passive-device technology for antenna-in-package applications

摘要

A new millimeter-wave antenna structure on a low-cost, production platform integrated passive device technology is presented. The antenna consists of a 2-by-1 array of slot antennas at 60 GHz. An in-house developed on-chip antenna measurement setup was used to characterize the fabricated antenna. The measurement results show an antenna gain of more than 5 dBi with a return loss of 18 dB at 60 GHz. The better-than-10-dB impedance bandwidth of the antenna covers the 60-GHz unlicensed band from 57 to 64 GHz. The 3-dB beamwidths of the antenna are 105° and 76° at E-plane and H-plane at 60 GHz, respectively. The size of the die of the antenna is 2 mm × 4.5 mm. © 2013 Wiley Periodicals, Inc.
