Integration of Yagi antenna in LTCC package for differential 60-GHz radio

Abstract

A Yagi antenna implemented in a thin cavity-down ceramic ball grid array package in low temperature cofired ceramic (LTCC) technology is reported. The antenna, intended for use in highly integrated differential 60-GHz radios, has achieved a 10-dB impedance bandwidth of 2.3 GHz from 60.6 to 62.9 GHz and a peak gain of 6 dBi at 62 GHz. © 2008 IEEE.
