Slot Bow-Tie Antenna Integration in an Enhanced Flip-Chip QFN Package for WR8 and WR5 Band Applications

Antenna-in-package integration is one of the vital research elements enabling the realization of future mm-wave front-end modules. This paper discusses the design, modeling and simulation of a slot bow-tie antenna integrated in an innovative flip-chip enhanced QFN package for WR8 (90GHz-140GHz) and WR5 (140GHz-220GHz) frequency application bands. Additionally, this work addresses the designs, models, and simulated data of chip-to-package transitions, transmission line feeds for the antenna. The integrated antennas have a -10dB bandwidth of 46GHz and 80GHz and a peak gain of approximately 7.1dBi and 8.45dBi in WR8 and WR5 bands. Finally, a brief description of the test vehicle for measurement is also presented.
