Abstract : In the recent era, Wearable
Technology is one of the promising and
challenging technologies.
Wearable Antennas are those antennas which
we can wear & that are designed to function while
being worn. It used for communication purposes,
which includes tracking and navigation, mobile
computing and public safety. It also has various
applications in the field of medical, mobile
communication, navigation and military.
Textile is used as a patch in such antennas.
Textile patch antenna uses fabric material for
substrate, patch and ground and it becomes part
of wearable clothing.
Ultra-wideband (UWB) is a range
of frequency (3 GHz to 12 GHz) used for
communication purposes, for the transmission
of data from transmitting antenna to receiving
antenna. It is an emerging technology that
promises high-speed data transmission at low
cost for wireless communications.UWB is the
best technology to be used for the purpose of
wearable applications.

I. INTRODUCTION :
To meet the requirement of wearable
applications, antenna should be small in size i.e.
.low profile, conformability, easy association
with other circuit components and very important
easy to bend & easy to withstand with moisture,
wet conditions.
