Abstract
The wide unlicensed frequency band around 60-GHz for wireless short-
range communications are receiving a lot of attention in recent years. As one of the
key components in wireless communication systems, the antenna technology affects
radio propagation channels, transceiver designs, and choice of digital modulation
schemes in establishing a reliable 60-GHz link. In this connection, the 60-GHz
antennas for wireless communications, especially antenna-in-package (AiP), have
received considerable attention and become a hot research topic. In this chapter,
wideband antenna arrays based on the multilayer low temperature co-fired ceramic
(LTCC) technology are presented and discussed for 60-GHz wireless short-range
communications applications.

Introduction
The wide unlicensed frequency band around 60 GHz with high data rate characteristic
for wireless short-range communications are receiving a lot of attention. For this
wireless communication, the data rate of short distance between electronic devices
can be realized in multiGbps which is 40-100 times faster than the current WLAN
technologies. Communications at the 60-GHz band have lots of advantages such as
the possibility of frequency reuse over small distances because of the high attenuation
by walls, and the possible miniaturization of the analog components and antennas
as the corresponding wavelength in free space is only 5 mm. 60-GHz band wireless
short-range communications have a number of applications such as uncompressed
high definition video streaming, mobile distributed computing, wireless gaming, fast
bulky file transfer, sensing and radar applications, virtually instantaneous access to
massive libraries of information, etc. [
