Developing antennas into textile material is a potential way for
facilitating many wireless applications, such as health monitoring of patients,
fire-fighting, rescue work, and space and military personal communications. The
increasing interest in wearable product such as medical devices, health
monitoring, sport wear and military domains promises to replace wired-
communication networks in the near future in which antennas play a paramount character.
They can play a vital role in monitoring heart, blood
rate or sending emergency signal for heart rhythm disorder and health
irregularities. Moreover, wireless communication system can be used to determine a soldier’s
physiological status including heartbeat, blood pressure, respiration and body
temperature. Body area networks have special features and advantages that make them different in comparison to other wireless
systems. The
devices
deployed within BAN have limited sources of energy due to their compact
and small size. Inspired by the idea of user centric propose to future communication technology, many research topics have been initiated, under the concept
of wearable devices,
to integrate antennas into the clothes with
regards to size reduction and
cost effectiveness. This paper
presents the possible investigation for the super wide band (SWB) MIMO antenna
made from 100% textile material. In this paper, SWB MIMO antenna presented for
wireless communication with three different substrate materials are presented
and implemented with textile material. This antenna resonates at frequencies
from 1.5GHz to 38.18GHz. In addition, the antenna provides with compact, low
mass, flexible, washable and robust material. Here, the performance of this
antenna in terms of return loss and radiation pattern deformation at different
frequencies is observed as well. Lastly, the antenna is verified by simulated
and measured result. Wireless body area networks (WBAN) are a natural
progression from the personal area network (PAN). Having such novel uses in
pervasive system for soldier, BAN is regarded as a promising interdisciplinary
technology that could have a huge impact on advancing Health-IT and
telemedicine with its widespread commercialization. In addition, the wearable
nodes can also communicate to a controller device that is located in the
vicinity of the human body. The effect of the human body on the operation of antennas located in close proximity has been investigated
widely and thoroughly
in open literature including the absorption of energy within the body and on specific
absorption rate (SAR) for proximate
antennas and of the propagation on and off the body.
